Cte of pcb
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. WebToday, ICs, semiconductor devices, solar cells, and PCBs are the main electronic applications where silicon is used. The Importance of Matching the CTE Silicon can bond …
