 Also, it is intended to ameliorate system accuracy aimed at colossal periodicity RF applications. The huge confrontation one expresses when producing this ilk of PCB is controlling the diverse quantity of caloric enlargement (CTE) tract of the divergent orbit materials. This is not only through PCB fabrication but also component throng.

It is highly important to note something when generating a PCB alongside disparate gear. You must have enough training in the phenomenal components of the foil and the potentiality of one’s apparatus. As a result in the CTE worth of the loop of these substances, something happens. Each substance develops at a varying degree during aerial heated uncovering or lamination. This can be the reason for weighty registration challenges as a material diminishes while another substance amplifies.

 Also, this can result to the peeling of the copper to coating linking. However, not every material can be a component of hybrid applications. This is because not all are manufacturable despite the preferred or wanted execution. Using one’s PCB fibber speedily during one’s design technique may result in achieving unprecedented after-effects as one is informed of the kinds of materials that can be best put together.

  • The thermal reading disparity between the elements of a circuit is minute.

Hybrid PCB

A hybrid printed circuit board utilizes different materials to build the substrate core layers and also the dielectric layers. Rather than using one material, the fabrication of hybrid PCB involves the use of different materials. Different materials are used to combine all positives into the manufacturing process of the PCB and reduce the negatives that a particular material may feature.

The positives may include exceptional strength, better signal performance, and a more stable dielectric constant. These negatives of these materials may include poor heat transfer, poor coefficient of thermal expansion, etc.  The major goal of utilizing dissimilar materials in the production of Hybrid PCB is to increase system reliability and improve electrical performance.

Due to this manufacturing process, this type of PCB is used in high-frequency Radio frequency applications. One of the greatest challenges that come with producing this type of board is handling the various CTE properties of the different circuit materials during the component assembly and PCB production. `

The fabrication of Hybrid PCB involves the use of PTFE laminates and FR-4 material. When designing a hybrid PCB, it is very important to know the appropriate materials used for it. The Polytetrafluoroetyhlene laminates and FR-4 material help to condense RF functionality on the PCB and as such, reducing the costs of the device.

Materials Utilized in the Fabrication of Hybrid PCBs

The fabrication of hybrid PCBs involves two major materials which are PTFE and FR-4. The layers of these PCBs can also feature several laminates in the same material like PTFE laminate filled with ceramic. The designer will have to change some of the material’s formula in order to develop different dissipation factors and dielectric constant rates to make the materials useful in certain applications.


PTFE material is a ceramic-filled plastics used for fabricating high-frequency PCBs. Due to the dielectric constant of this material, it is suitable for applications that require improved impedance control and low signal loss. Polytetrafluoroetyhlene is a type of material that is also utilized for applications that will be subjected to higher temperatures since it offers great mechanical stability.

However, PTFE has its own disadvantages since it is a more expensive option. It will also experience dimensional changes being the fact that it is a softer material.


FR-4 is a type of material commonly used in the fabrication of a printed circuit board. This material which is also known as Flame Retardant 4 maintains a good standard in the PCB industry. It is mostly preferred because of its low costs. This material features exceptional electrical insulation and high dielectric strength.

Due to the features of this material, it is useful in a variety of applications. Although there are some downsides of this material, it is still a suitable option. This material features properties that don’t make them suitable for higher frequencies that are recently developed.


Polyimide is another type of material that can be used for the fabrication of a hybrid circuit. This material features high chemical resistance which enables them to withstand some chemicals. Asides this feature, polyimide have great electrical properties and can be used in various applications.

Polyimide is a lightweight and flexible material that is ideal for portable applications. However, polyimide is a less considered option since they are more expensive than PTFE and FR-4.

Why are Different Materials Used for Designing Hybrid PCB?

One of the unique features of Hybrid printed circuit boards is the dissimilar materials used in their manufacturing process. Dissimilar materials are utilized for some reasons. The primary purpose of utilizing different materials to fabricate multilayer boards is to reduce poor structural and mechanical characteristics of some of the laminates.

When these laminates are combined, they complement each other by reducing the negative properties of some materials and increasing the strength of some properties. For instance, PTFE offers great electrical properties but it can have issues with its structural properties when exposed to certain temperatures.

Combining different materials also help to reduce the costs of fabrication; hence it is a budget-friendly option. Most times PTFE and FR-4 are utilized in designing hybrid PCBs. PTFE laminates are utilized for high-speed functions while FR-4 offers enough advantages for low speed applications. Furthermore, FR-4 materials can be utilized to balance the thickness issues for the layers of these laminates.

Issues to Consider when Designing Hybrid PCBs

There are certain things that should be put into consideration when designing a circuit board that features different materials. It is important to understand that each material has different CTE values. The values represent the level of dimensional changes each material will undergo when exposed to varying temperatures.

This can result in registration issues as one laminate expands while another shrinks. Therefore, it is important to note that some materials shouldn’t be utilized in hybrid applications. Layer separation is an important problem that must be solved when fabricating multilayered hybrid PCBs. Delamination is another issue that can also happen. In this case, the laminate layers begin to peel off.

To tackle the issue of delamination, knowing the period of delamination for materials is very important. The stack-up process is another major issue experienced when designing hybrid PCBs. Fabricators must have the appropriate thickness for the circuit board for every piece and panel in order to meet the required thickness without affecting the needed frequencies. Depending on the type of materials utilized, the adhesive system utilized for hybrid circuit board varies. The printed circuit board will have the appropriate thickness if the right amount of insulation is provided.

Not all companies have the experience or skill required to design hybrid PCBs. PCB fabricators may work with certain materials. Furthermore, the fabricator will have to understand certain issues that happen while etching multilayer boards. Having a discussion with the fabricator will help them understand what you want. They can also give suggestions about the type of material that can be utilized.

When Should Hybrid PCB Stackup be used?

There are different factors that determine when to use hybrid PCBs. The costs, the temperatures, the applications’ functions, and the frequencies are some of these factors. One of the benefits of hybrid PCB stackups is that it enables you to increase your creativity when fabricating the circuit board that will have the mechanical and electrical properties needed.

Cost considerations are also very important when it comes to hybrid designs. Since hybrid PCBs involve the use of dissimilar materials, you can benefit from using a cheaper material in places that don’t need higher frequencies. You can then use smaller amount of the expensive materials for sections of the PCB that need greater electrical, thermal, and mechanical properties.

Mechanical Features of a Hybrid PCB

During the fabrication of Hybrid PCB, some PCB designers desire some unique mechanical features that may be complex to include. Some of the features are

Odd shape board outlines

Most times, these laminates must fit into other space and there are times when the printed circuit board features different turns and twists. For a hybrid design, routing the outline of the PCB is a sensitive procedure. The speeds and feeds must be reduced to ensure that the edges remain crisp.

It is also important to monitor your drill bits since the material is more complex on drill bits. You should also be aware that most RF materials can fray easily if they are not properly cut.

Plated through hole consistency

A fabricator must understand that hole preparation before plating for FR4 is different. The way these processes affect the quality of the hole wall must be understood. For PTFE, you must use plasma etch process to desmear the holes. This is not the ideal method for FR4 as it can result in an uneven surface which will then lead to uneven copper in the holes.

Controlled depth rout process

Some of the mechanical features of hybrid PCBs result from utilizing several lamination cycles while others are as a result of utilizing a controlled depth routing patterns. However, these processes have their own problems which can add complexity and cost to the PCB design.

A manufacturer must rout out the pattern in the prepreg and the production pattern when utilizing several lamination cycles to build these cavities.
