Electronic Gear Shifter FPC

Hongyi Precision R&D validated extensive assembly motions and determined that connector pads, soldering pins, and external mounting areas require stiffeners—stainless steel or rigid PI—with thickness ≥0.1 mm to enhance plug-in and assembly strength; stiffeners must not be applied in dynamic bending zones to avoid restricting flexibility and causing stress-concentration fractures.
