Introduction

Connecting flexible printed circuits (FPCs) in electronic devices often requires using specialized connectors designed for soft and pliable conductors rather than rigid boards. The two main categories of flexible connectors are FFC (flat flexible cable) and FPC (flexible printed circuit) connectors.

While related, FFC and FPC connectors have distinct characteristics and applications. Understanding the key differences allows selecting the optimal solution for integrating flex circuits into designs.

This guide will examine all aspects of FFC and FPC connectors from materials, design, interfacing, pros and cons, and recommended use cases. By the end, the distinction between connector types and appropriate selection for flex circuit applications will be clear.

FFC Connector Overview

FFC or flat flexible cable connectors are designed to interface with flexible flat cabling. Typical FFC connectors consist of a plastic housing containing a clamping mechanism and set of conductive pads or pins.

Typical FFC Construction

• Flat flexible cable terminated with thin PCB ends
• Insulation carrier material with exposed copper conductors
• Laminated polyester, polyimide, or polyether ether ketone (PEEK)
• ZIF (zero insertion force) style connector mating
• Pitch options from 0.3mm to 1.27mm

FFC cables excel at interconnections over dynamic bending locations between PCBs where a standard wire harness would fail prematurely. The smooth flat shape avoids issues with tangled conductors.

Common applications include disk drive flex cable interconnects, printer carriages, LCD displays, and device hinge connections. The ability to accommodate continuous motion over thousands of cycles with high reliability makes FFCs ideal for these applications.

FFC Connector Styles

While designs vary between manufacturers, FFC connectors come in two primary styles:

Clasp/Latch Type

• Plastic connector housing with metal spring latch
• Latch presses FFC cable into contact pads
• Locking clasp prevents disconnects
• Unlatching enables FFC cable insertion/removal
• Low profile above PCB

Slide-Lock Type

• Housing with movable side locks
• Locks slide forward to press cable into connection
• Reverse sliding releases pressure on cable
• Locks prevent disconnect under vibration
• Provide audible click when engaged

Both styles offer reliable connection for FFC cables under dynamic bending. The latch type focuses on slim form factor while the slide-lock aims for robustness.

FPC Connector Overview

In contrast to FFC connectors, FPC connectors are designed specifically to interface with flexible printed circuit boards rather than raw cable.

Typical FPC Construction:

• Flexible PCB material with conductors on one or both sides
• Polyimide is the most common base material
• Adhesive layer bonds to additional stiffener layers
• Components often attached directly to flex PCB
• Connectors mounted to tail sections

FPCs allow complex flexible circuit boards to be designed with fine features, tight tolerances, and components while still supporting dynamic contours.

Applications such as folding device hinges, concealed / slide-out device interconnects, and wearable or skin-contact electronics benefit from FPC technology. The tailored flexible PCB provides reliability and robustness beyond basic flexible cabling.

FPC Connector Styles

Common connector styles used with FPCs include:

Pressure Actuated Contacts

• Gold plated copper alloy contacts
• Contacts wipe FPC conductive pads
• PCB pivot / lever actuation
• Spring or screw force enables reliable contact
• Wiping action penetrates oxidation

ZIF (Zero Insertion Force)

• Movable side pins align FPC tail
• Cam, hinge, or latch mechanism actuates pins
• Pins pressed into plated through holes
• Enables fingertip mating connection
• Lock prevents vibration disconnect

Well-designed FPC connectors tolerate millions of matings despite presence of vibrations, contaminants, and other challenges.

Key Differences Between FFC and FPC Connectors

What are FPC and FFC?

The first thing you need to know about the two different types of flexible circuits is what they are. FPC stands for Flexible printed circuit. The other type of flexible circuit is the flexible flat cable. These two types of flexible circuits have a similar structure but differ in cost and manufacturing process. In this article, we’ll discuss both types and how they work. After learning their differences, you can choose the best type for your project.

Flexible printed circuits

Flex circuits are flexible and can bend into the desired shape. They are ideal for small interior spaces, but the production quality is much less stable than for rigid circuits. Flexible circuits consist of thin, film-like materials, including copper foil. Different materials have different shrinkage, and warpage characteristics, so careful design is essential. The following tips will help ensure the highest quality flex circuits.

Flexibility is one of the essential advantages of flexible circuits. Unlike rigid circuit boards, we can manipulate flexible circuits often during assembly, installation, and service. These advantages allow for a high-density device population, lighter conductors, and improved airflow. Flexible circuits will work for you whether your application is small or complex. They are also extremely versatile and can connect various components. An innovative PCB manufacturer designed flexible printed circuits ideal for various applications.

Flexible flat cable

What is a flexible flat cable? A flexible flat cable is an electrical cable made with flat solid conductors. The flexible flat cable is essential for various applications in the electronics industry. Flexible electronics refer to the technology that enables a device to be more flexible. Its unique properties allow it to fit in different places and can be used to power various electronics. Read on to learn more. Here are some examples of a flexible flat cable.

A flat cable’s pitch refers to the spacing between the wire conductors. This distance indicates the pitch. Different cables have different pitches, but common values are 0.5 mm and 1 inch. The pitch of a cable will indicate its ability to accommodate a variety of applications. In addition, the pitch of a cable will affect its flexibility and strength. For example, high-speed ATA interface cables are made with 0.025-inch pitches and have a 0.1-mm pitch.

Pinouts

If you’re trying to connect two computers or other electronic devices, you may wonder which connector to use. FPCs are ideal for straight-through connections, while FFCs are often layered and impedance controlled.

FPC wiring is a flexible circuit board made from a flexible polymer base coated with a protective polymer coating. Because it’s flexible, you can customize the number and spacing of wires. FFC is especially useful for electronics that require a high degree of flexibility. Flexible solar cells, for example, can be made to fit within the spacecraft’s shell. This circuit board is also lightweight compared to the rigid PCB board.

Applications

The similarities between FPCs and FFCs extend to their various applications. For example, both types have copper wires and a thin film of chemically etched copper on one side. They are essential in LCD televisions, printers, cameras, and laptops. In addition, they are ideal in the aerospace industry. However, FPCs are more sophisticated than FFCs. They consist of polyethylene terephthalate (PET), copper wires, and other flexible materials.

Unlike other types of connectors, FPCs have a flat, flexible body with a barrier framework that we can organize after installation. This framework also provides a specific stabilization force. In addition, these connectors are strong and rigid enough to resist shock and vibration. Moreover, they have locking components to lock the connectors. For example, Amphenol makes a vibration-proof FFC and FPC with a 2.49mm pitch.

The Difference Between FPC and FFC?

You may have heard about the terms Flexible flat cable and Flexible circuit. But do you know the difference between these two? How do you know which is better? We’ll explain the differences between these two cables and help you make the right choice for your projects. So, what is the difference between FPC and FFC?

Flexible flat cable

If you’ve ever wondered whether the differences between a flexible flat cable and a traditional round electrical wire are worth the hassle, read on to learn more about the two. Unlike traditional round cables, flexible flat cables are thin and lightweight, making them a popular choice among designers. In addition to helping designers save space, they can add an innovative touch to their designs.

Pitch is the primary difference between a flexible flat and a standard flat cable. Pitch is a measurement of the distance between the centers of two adjacent wire conductors. These cables are often helpful in medical products, industrial automation, pulp and paper, festoon systems, packaging, and semiconductor products. They are also widely used in stereos and scanners, with many other applications. You can find them just about everywhere in modern electronics.

Flexible circuit

In contrast to rigid circuits, flexible circuits can be flexed and maintain their form. They consist of a thin insulating polymer film with a pattern of conductive traces. They have been in use since the Second World War, but their popularity is growing today. There are two main types of flexible circuits: single-sided and double-sided. Single-sided flex circuits have only one metal layer. They add Polyimide or FR4 overlays for added insulation and protection against environmental degradation.

Polymer thick film flex circuits are a subtype of the flexible circuit. We manufacture them by printing the circuit elements onto a thin polymer film. The result is a thin, flexible layer of electrical components. Polymer thick film flex circuits are typically single conductor layer structures, though two or more layers can be printed in a sequence separated by insulating layers. While they are generally less flexible, we can make polymer flex circuits with varying amounts of metal.

Flexible circuit cable

There are many advantages of FFC over FPC for electronic enthusiasts. These cables feature a wide range of capabilities and components. As a result, users often feel confused when choosing which type of cable to use. FFC cables are commonly helpful for high-density electronic applications.

The construction material is the main difference between an FPC and an affixed FFC cable. FPCs are thinner and have thinner conductor layers. FFCs are helpful in LCDs and motherboards. FPCs are made of copper, coverlay, and PI and are customizable in shape and pattern. We can bundle these types of cables together to fit a variety of applications.

Cost

In general, FFC and FCCL cables are similar to each other, but they differ in their cost and applications. We can make these cables with single or double-sided copper wires. They require a chemical etching process and have various layers of coating. The FCCL process produces thicker FFCs. However, some companies use both types of cables for specific projects. When choosing the type of cable to use, consider each material’s application and cost.

Molex offers a line of FFC/FPC connectors. The line of connectors offers a wide variety of profiles, including those with push-style and flip-style actuators. These connectors also come in higher-density versions. A common application for FFC/FPC connectors is in medical equipment. Its versatility allows it to work with different types of cable styles and different circuit sizes.

Connectors

Amphenol offers reliable, flexible, and high-performance connectors for connecting FFC/FPC circuits. The company’s micro flex connectors are available in various sizes and pitches, making them ideal for various industrial applications. Other FFC/FPC connectors available from Amphenol include ClincherTM and DuflexTM, which are excellent for industrial and modulation applications and shock and vibration-prone environments.

In general, FPC cables and connectors cost less than FFC connectors. Companies concerned with costs often choose FFC designs, but they are more practical. The differences between the two are not so noticeable, but they are essential to know. If you’re looking for a high-quality connector, look for one with an internal FPC connector with a 0.3mm pitch.

Summary

You may have heard of Flexible Printed Circuits (FFC), but you might wonder what the difference between them is. These circuits are made from copper and polyimide material and are flexible enough to handle harsh conditions. These circuits are often helpful in LCD televisions, laptops, printers, and other applications where space concerns. There are two types of FPCs: single-sided and double-sided.

One of the main differences between FFC and FPC is how they construct. FFCs have straight-through conductors, while FPCs have multiple traces that can be bent, angled, or tied to a shield. As a result, FPCs are more flexible and are ideal for data cables. FPCs can also have varying pinouts and impedance levels. Depending on the application, you may need to choose an FFC or FPC that works well for your application.

FFCs are thicker than FFCs. They consist of two layers of wire, one insulating foil, and one flat copper conductor. FPCs are helpful in tight spaces and for high-speed applications and are often essential in vehicles. However, they are also more difficult to bend, making them less flexible. So if you’re trying to figure out which connector to use for a particular application, consider FPCs.

Flat Flexible Cables can be helpful in several applications. For example, LCDs and other electronic devices may connect using FFCs. A standard FFC will have one contact on each end, while FFCs with opposite contacts require a connector.

Did you know that IOT sensors are crucial to human development? It is very important to note that you can find sensors everywhere. Also, it could be said that these sensors are as old as man. This is because for every technological advancement, sensors are part of it.

The IOT sensors are in schools, machines, homes, malls, cars, hospitals, airplanes, and other places or facilities you didn’t know they could be present.

In this article, we shall discuss elaborately on 17 different types of Internet of Things referred to as IOT sensors. Also, we shall consider their unique features and frequently asked questions about this subject matter.

What Do IOT Sensors Really Mean?

As earlier mentioned, Internet of Things makes our lives easier and these sensors are in use for our daily activities. Our smart phones are functional because of the sensors present in them.

Sensors are tools that easily identify changes around us. Thus, they don’t only identify these changes, they react to them. Across the globe, many industries use different types of sensors. To simply put, sensors are integral parts of all organizations in the human space.

With the availability of sensors, we can collect data. At the same time, we share this data with wide range of connected appliances. Therefore, it is safer to say that our world “runs” on sensors. Also, the IOT space is becoming broader everyday. Furthermore, there are more data that we process and transmit new facts, figures, information, and statistics to huge archive or data bank.

Additionally, the IOT sensors have wide range of devices which provide network via software that can collect and send data through the Internet.

Interestingly, every IOT tool can gather massive data from their surroundings. This data may include several things such as human behavior. Also, it can gather data about weather conditions, climate change, and detect human response to the environment.

Also, IOT tools can transfer data collected from our environment for processing through digital devices without interference from us. We don’t have to analyze data ourselves from time to time. Also, devices format data in ways that both humans and different tools can understand.

The Major Types of IOT Sensors in the IOT World

In this part of the article, we shall consider 17 types of Internet of Things sensors that have shaped the human existence. They are all applicable to various industries you can think of.

Temperature Sensors

The temperature sensors have become so useful in various industries. Thus, this type of IOT sensors has great influence in our ecosystem. Also, you can observe how refrigerators work. The temperature sensors can easily expose the temperature of such object. It can transmit the degrees at which there is hotness or coldness of an atmospheric condition.

Also, the temperature sensors can calculate volume of heat intensity from any source. Similarly, it can reveal the degrees of temperature modification in an object. Therefore, it alters such modification, converting it to data for future purpose. So, this type of sensor works for agriculture because one needs to control temperature around the farmland.

This type of sensor has at least four groupings. They include the following.

 RTD: This is simply the Resistance Temperature Detectors. Also, this tool can calculate temperature based on modification in resistance. Also, one can observe the film and coil of this device.

Semiconductor: This device reads temperature and is regarded as minute chip. It works as amplifier and oscillator. Interestingly, this tool saves computer memory.

Thermocouple: This tool calculates temperature thereby storing up alterations in voltage. One thing is, its output voltage is influenced by degrees of temperature at such particular time.

Thermistor: This device easily reacts to alterations in temperature. This implies that, it can modify its resistance physically as a result of detection of temperature modification.

Proximity Sensors

Sometimes, proximity sensors are taken as motion sensors. However, they serve varying purposes. So, one can’t conclude they are similar. Furthermore, proximity sensors can calculate and detect any distance from a device. Thus, it doesn’t necessarily have to physically come in contact with any object before proximity sensors can detect distance. They are available in IOT applications.

Proximity sensors can quickly sense mobility and that is why proximity sensor is widely common in any retail sector. Also, proximity sensors are great at detecting close contacts on connected devices. Again, you find proximity sensors common in places such as airports, shopping centers, mortar stores, convenience stores, and stadiums.

Furthermore, proximity sensor is grouped into ultrasonic sensor, capacitive sensors, and inductive sensors. Also, proximity sensors use some photoelectric technicalities to detect nearby contacts. The use of light is important in this case.

Pressure Sensors

As the name implies, pressure sensors deal with calculating the pressure applicable to any form of sensor. Thereby, pressure sensors can work on atmospheric force. Pressure sensors calculate the volume of pressure that a fluid needs so as not to dilate. Also,  pressure sensors work for industrial apps.

Interestingly, this sensor can calculate weight of an animal because it measures volume of pressure used per unit. Also, pressure sensor is a type of the IOT sensors can detect alterations in fluids which could be gaseous or liquid. As long as the force modifies, this sensor senses such changes. Therefore, it transmits the data to connected devices.

Optical Sensors

This class of sensor works with light conversion. This implies that optical sensors change light to electronic indicator. Today, we have countless use cases where optical sensors are functional. Commonly, optical sensors work for vehicles. This is because optical sensors respond to signals. So, a driver can detect alterations while driving because optical sensors can process any obstacles.

Electrical coils can be described as an electrical conductor. This is usually wound to form a coil, a spiral, or a helix shape. They have a major function, which is the transmission of electricity, heat, or sound.

Furthermore, the electrical coils are also called electromagnetic or magnetic coils. This terminology could cause some form of confusion. This is because the word electromagnet could specifically have to do with electric coils. These coils directly affect any external object via a magnetic field.

How Do Electrical Coils Work?

Although electrical coils serve in many different applications, the majority of electric coils usually share similar electromechanical principles and basic construction.

Furthermore, the electrical coils come to be whenever a specific conductive metal wire is wired around a specific insulator. The whole wire is called the winding, then each of the individual loops present in that winding is called a turn. Also, there is a hole in the coil’s center. We refer to this region as the magnetic axis or core area. Same way, both ends of this wrapped wire are usually changed into different terminals for electrical connection referred to as “taps.”

Furthermore, the creation of power happens whenever there is a link of the taps to a specific electric current that moves via coiled wires and then magnetizes the coil.

This can happen due to the fact that the electric currents flowing creates a form of circular magnetic field. This is present along the entire conductor’s length. Also, the coiled electric conductors help in creating a stronger magnetic force compared to the straight conductors.

This is because they manufacture similar or the same magnetic fields that merge at the loop’s center. Also, the electrical coils that are made up of many electric loops which are wound round that same axis, could yield magnetic fields that are very strong.

What are the Electrical Coil Materials?

Although lots of conductive metals exist, Copper and aluminum are most frequently used in making electrical coils. Also, these Electrical coils mainly for heating purposes are usually made up of an iron or nickel alloy. Regarding the insulator, you can manufacture it from some non-conductive and diverse materials, which includes air, cardboard, enamel, or plastic.

Furthermore, the insulation of coils are usually done specially; this is majorly to help in preventing the flow of current between the coil turns as well as shielding the coil from long exposure to any corrosion as well as damage-causing conditions such as vibration, oil, moisture, or salt. You can protect your coils in different ways:

First is encapsulation, and this applies just to the coils’ wire. The encapsulated coils are also made up of wire, which is already covered in a specific polymer epoxy. Also, the molded coils have plastic coverings, which seals both the wires and the whole winding.

There are several PCB companies across the world. However, not all of these companies are incorporated. Some PCB users are very careful when selecting the type of companies they work with.

As a PCB manufacturer, you should register your business with a state to make it a separate legal entity. Here, we will be discussing PCB incorporations.

What Does Incorporation Mean?

Incorporation which is popularly referred to as inc. indicates that a company is registered with a state so as to become a separate legal entity. Incorporation involves the legal process required to create a corporate company or entity. Therefore, a corporation separates the assets and income of a company from its investors and owners.

Inc. is simply an abbreviation of incorporated. Any company that has this abbreviation is a legal corporation. Some PCB companies are a legal incorporation. One can simply say incorporation is the process in which a business is a corporation. Therefore, the business earns the right to have an inc after its name.

However, the rules of incorporation may vary by state and the particular corporation type you want your business to be. Also, you need to first choose the type of corporation you want and then select the state to incorporate in. The best option is your home state. However, some corporation owners select states having favorable corporation laws.

Also, incorporation makes it much easier for businesses to raise capital. An incorporated business becomes a separate entity from the owner of the business. This means the company is a legal entity in its right.

The constant development of electronic devices has increased miniaturization. Also, PCB size keeps shrinking. Therefore, there is a great need to improve the soldering process. Using soldering flux to solder the hole to the motherboard usually leads to cold solder. Therefore, there is an increasing demand for castellated pads.

What is a Castellated Pad?

A pad is crucial for PCB design. In a circuit board, a pad is the exposed area of metal in which the component lead is carefully soldered to. when we talk about castellated pads, we mean vias or PTH located in the PCB edge. Castellations create several half holes. These holes function as pads that create a connection between the PCB and the module board.

Castellated parts are usually applied to the edges of a PCB. Also, they help to solder a circuit board on top of another. Castellations are like indentations created on PCB edges. These castellations make it easy to mount a circuit board on top of another.

Attaching a circuit on top of another creates opportunities for various design options. Castellated pads make the PCB assembly process much easier. However, these castellations may be half holes or a part of a broken circle. Also, these castellations offer good alignment between two circuit boards. Therefore, castellated pads aid the soldering of boards.

Furthermore, castellated pads help the board-to-board soldering. Castellations serve several functions. You can use them in various PCB modules.  The process of creating castellated pads is quite straightforward. Also, this process involves drilling and plating the full holes in the castellated PCB. Furthermore, castellation involves cutting the top region into halves. Therefore, this creates partial or half holes on the circuit board’s edge.

Why is Castellated Pad Crucial in PCB Design?

Castellated pads can help to replicate some PCB parts. For instance, if a circuit features feedback loops, an inverter, or a filter, you can produce these sub-circuits and then solder them on the main circuit.

• Castellated pads can change the pin layout of the component based on user requirements.
• Castellation makes it easy to mount circuit boards to another PCB
• Also, a castellated PCB can serve as a breakout board for a certain part of your larger circuit board.
• They help in combining two circuit boards to validate the quality of solder joint.
• Castellated pads can help you design integrated modules on a PCB.
• Also, they are suitable for use in small modules like breakout boards and Wi-Fi modules.
• Castellated pads enable complicated components to be integrated with a breadboard.
• They enable electrical connection to another board via the edges of the board without the need for additional components.

Recommended Specifications for Castellated Holes

There are some recommended design specifications for castellated holes.

Size

Use the biggest size available, this will help you mount PCB correctly

Pad design

It is much better to use the biggest pad. Integrating the largest pad for every castellation enables the PCB to fit well

Distance and diameter

Half holes are ideal for use in both advanced and standard circuit boards. The minimum hole diameter for a standard circuit board should be 0.6mm. Also, the castellated holes diameter for advanced circuit boards should be smaller. Note that the minimum distance between two castellations should not be lower than 0.55mm.

Surface finish

The surface of a circuit board is crucial for mounting PCB correctly. Also, ENIG finish is one the best surface finishes for circuit boards. However, the intended application of the PCB will determine the type of surface finish you opt for.

How to Design a Castellated Board

You have to ensure high yield and quality when designing a castellated board. The process of designing a castellated circuit involves designing castellated pads. Also, this process is a complex one. However, any costly mistake will affect the performance of your circuit board. You need to understand some things when designing a castellated pad.

Half hole PCB

Half hole board features a part of a broken circle. When designing this castellation, the PCB designer must be aware of some crucial things. Below are factors to consider when designing half hole.

• Holes with smaller lead-in holes

These holes are ideal for use in any connector application. Also, they require a cutting tool which helps in creating other smaller castellations where needed.

• Use the bottom and top edge as the location of the hole

Avoid utilizing the vertical edges. This is because these edges usually function as bridges. Therefore, this ensures the circuit board bridges in place.

There are various designs for half holes. However, they vary based on their software.

How to Fabricate a Circuit Board Castellated Pads

When fabricating a circuit board with castellated pads, you need to ensure high yield and quality in the process. However, castellated circuit boards don’t appear to fit in the PCB fabrication process. Therefore, you can ensure the design passes through fabrication. You can achieve this by simply modifying the Gerbers to specify drill hits. This usually needs the following drill files (TXT/DRL) and copper layers (GBL and GTL).

Some fabricators believe that the best alternative to castellated boards is integrating solder pads to mount the module. However, the main challenge here is the possibility for contamination. Too much of solder paste along the pad array can lift the module.

The manufacturing process for castellation pads involves the following steps:

• Drilling of holes
• Ensuring plated hole
• Creating panel plating
• Performing image transfer
• Performing pattern plating
