Copper Film

Copper foil: Basically divided into electrolytic copper and rolled copper The common thicknesses are 1oz, 1/2oz, and 1/3 oz

Substrate film: There are two common thicknesses: 1mil and 1/2mil

Adhesive (adhesive): The thickness is determined according to customer requirements

Cover Film

Cover film protective film: used for surface insulation The common thicknesses are 1 mil and 1/2 mil

Adhesive (adhesive): The thickness is determined according to customer requirements

Release paper: To avoid adhesive adhering to foreign objects before pressing; Convenient for homework

PI Stiffener Film

Reinforcement plate: It enhances the mechanical strength of FPC and facilitates surface installation operations. Common thicknesses range from 3mil to 9mil

Adhesive (adhesive): The thickness is determined according to customer requirements

Release paper: Avoid the adhesive from adhering to foreign objects before pressing

EMI: Electromagnetic shielding film, which protects the circuits inside the circuit board from external interference (strong electromagnetic areas or easily disturbed areas).
