What Role Does Underfill Play in Rigid Flex Circuits?
Underfill Play in Rigid Flex Circuits Rigid flex circuits are combinations of rigid PCB sections with a flexible printed circuit board attached. They are often used in applications where a small footprint is required, space optimization, or unique form factors are needed. Rigid-flex boards also offer EMI protection and shielding, and signal integrity. To make a rigid-flex board, first the
