WebWhile they are more expensive, polyimide PCBs offer impressive flexibility and functional benefits over traditional FR4 boards. Lightweight, flexible and durable, polyimide PCB boards have the potential to solve many PCB integration and design problems, making them cost-effective in the long run. WebWhen it comes to PCBs, the most important variable to account for is CTE (Co-efficient of Thermal Expansion) of each of material. It is critical to match materials with correct Z-Axis CTE values so that you can minimize the expansion of the material in operation, which can cause de-lamination or hole-wall separation in the metal core PCB.
