What are the Functions and Features of FPC Battery Connector?

Flexible printed circuits (FPC) were created to satisfy market demands. Some mobile or wearable gadgets demand high current features, such as brighter displays. For sure, t his pattern will persist. Therefore, this requirement is at odds with the trend toward thinner and lighter electronics that we see every year. Batteries must also be smaller and lighter.

In order to conduct higher currents, the connector found between this battery and the circuit board must be tiny. FPC Battery connector is the main topic of this article.

What Does an FPC Battery Connector Mean?

The lithium ultrathin ceramic battery with flexible printed circuit (FPC) is created in a method that bypasses the processes used by conventional lithium batteries.

Flexible circuit boards are included into FPC battery connector as base and packaging materials. The  size of the ultrathin battery is small. It is therefore simple to carry. Additionally, because the battery comes safe, it cannot explode or catch fire or burn.

Additionally, this battery will tolerate low temperatures, high temperatures, and physical impacts. FPC Battery connectors may be linked to the circuit board and is relatively simple to assemble. The flexibility radius of this battery is also between 15 and 17 mm. Even after being subjected to overload tests using extremely high external voltage, this battery cannot explode or catch fire.

The battery pack is protected by the FPC battery connector. FPC, or flexible printed circuits, is another term for a protective circuit module.

The FPC battery connector is also perfect for usage in different flexible devices. They are present in wearables like smartwatches and healthcare monitoring devices. Lithium polymer is included into these gadgets.

A base film as well as several wires formed on the base film makes up the flexible printed circuits. Carrying the FPC battery connector is quite simple. This battery cannot cause explosion, leakage, or fire when put through various temperatures, physical impacts, as well as electrical damage tests.

It functions as an FPC battery connector for smartphones, tablets, as well as some wearable technology. To be used in NFC devices, FPCs are perfect. Additionally, this battery is frequently included with this NFC chip because it makes sense to connect from there.

FPCs are made by grafting on the flexible copper clads as well as cutting it into various layer sizes.

What Characteristics Does FPC Battery Connector have?

FPC battery connectors

Exceptional retention power

The battery is compact and has a very thin profile, yet it has a greater retention force. As a result, when these batteries are utilized in devices, this improves their performance. In addition, the FPC battery connector can also hold onto stored energy to serve a longer time.

Highly reliable connections

This FPC battery connector delivers great connection reliability despite having a slim appearance. Because of this, it excels as an FPC battery connector to serve portable electronics.

Really effective assembly

When attaching a socket onto the header, this battery achieves excellent assembly efficiency alongside easy of positioning.

What Distinguishes the FFC from the FPC?

Most of the time, FPC and FFC are confused. In the Circuit board industry, these terms are interchangeably used. FPC as well as FFC are completely different even though they both offer extensive functionality. So how can you tell an FPC battery connector from an FFC connector?

The first distinction is actually in what they signify. While FFC stands for flexible flat cables, FPC stands for flexible printed circuits. Additionally, flexible printed circuits are the FPCs, whereas a flat, flexible cable is an FFC. Films with a metallic termination which is perpendicular to the base make up FFC connectors. On the cable board of the FPC battery connector, there is an inserted or a printed circuitry known as FPC.

FPC and FFC have distinct duties. In-depth integration of FFC cables is used in high-flex applications. Additionally, FPC can be found in LCDs, printers, antennas, etc.

FPCs have evolved over time. FPCs and FFCs are distinct from one another in terms of how they are made. FPCs are made by grafting on flexible copper clads and then cutting it into various layer sizes.

FFC, however, involves laminating flat PET with copper wires. Its increased thickness results from this. FFCs are also designed specifically with many wire layers. These connectors differ among themselves with respect to thickness as well.

FFC can be used in thicknesses between 0.5mm to 2.54mm. FPC cables, meanwhile, come in a variety of thicknesses between 0.15mm to 0.2mm. Furthermore, there are several different FFC manufacturing techniques. FFCs, in comparison, are somewhat weak. High conductivity components are found in FFCs.

As a result of their differences, both connectors cannot be interchanged.

FPC Battery Connector components


Circuit boards as well as the flexible printed circuit are connected using the FPC battery connector. The FPC battery connector consists of three essential components. These consist of:


A constant contact performance is guaranteed by the terminal. To accomplish this, it incorporates a limited contact strategy. Additionally, it chooses materials with excellent mechanical qualities.

Plastic Body

After installation, you can arrange this barrier framework, which resembles a sheet. Additionally, this acts as a sort of stabilizing force. In accordance with the requirements of your application, this plastic body must be hard and strong. Additionally, there must be no wrap deflection while handling SMT soldering.

Card Lock

During the implanting of the FPC/FFC, the fastening components assist in locking the FFC/FPC to maintain a specific contact force. As a result, the components must be stiff and rigid.
