GESP TECH -TRUSTWORTHY ONE-STOP PCB SERVICES HYBRID PRINTED CIRCUIT BOARD
A hybrid PCB is a composite-structure PCB that utilizes more than one base material type to provide desired electrical properties such as heat sinking, high-speed signal transmission, reception, and so on. The reliability of hybrid PCBs increases many folds with the right combination of substrates. Indeed, different substrate materials with differing dielectric quotients and coefficients of thermal expansion increase PCB electrical performance.

BENEFITS OF HYBRID PCB
Hybrid PCB Materials Features Such As :
- The high heat conductivity of ceramics, copper, and aluminum.
- The high-speed characteristics of PTFE.
- Flexibility of PI and PET,
- The transparency of transparent PET and glass.
- Excellent solderability of FR4, etc. In addition, the hybrid PCB’s composite structure is tailored to your application specifications.
THOUGHTS ON LAMINATE CONSTRUCTION FOR HYBRID RF PCBs
When making a PCB out of different materials, it’s very important to know both the physical properties of the laminate and what your equipment can do. Depending on the CTE values of each layer of material (such as FR4, PTFE, and copper), each material grows at a different rate when exposed to high temperatures (i.e. lamination). This can cause big problems with alignment when one material shrinks and another one grows, and it can also cause the copper-to-substrate interfaces to come apart. So, not all materials should be used in hybrid applications because they can’t be made, no matter how well they work.
APPLICATION OF HYBRID PCB
The trend of high-density, compactness, and shrinking of electronics is met by hybrid PCBs. Nearly all middle- and high-end industries, including aerospace, wireless, high-power, automotive, industrial, medical, defense, and commercial electronics, can benefit from the use of hybrid PCBs. For instance, the copper/FR4 PCB is utilized for the central air conditioning system in the images above, the ceramic/copper PCB is used for stage lights, and the hybrid RF PCB combining 4 types of base materials is used for defense.
