FFC cable is translated into Chinese, that is, flexible printed circuit board, generally speaking, soft material connector is used to connect LCD display screen to drive circuit. Currently, 0.5mm pitch products are mainly used, and 0.3mm pitch products have been widely used.
Basic structure of FFC cable arrangement
Copper foil substrate
Copper foil: basically divided into electrolytic copper and calendered copper. The common thickness is 1oz 1 / 2oz and 1 / 3oz.
Substrate film: common thickness is 1mil and 1 / 2mil.
Glue (adhesive): the thickness depends on the customer's requirements.
Cover film protection film
Covering film protective film: for surface insulation. The common thickness is 1mil and 1 / 2mil.
Glue (adhesive): the thickness depends on the customer's requirements.
Release paper: avoid adhering foreign matters before pressing; easy to operate.
Reinforcing plate: it is used to strengthen the mechanical strength of FFC cable arrangement, which is convenient for surface real installation. The common thickness is 3mil to 9MIL.
Glue (adhesive): the thickness depends on the customer's requirements.
Release paper: avoid adhering foreign matters before pressing.
EMI: electromagnetic shielding film to protect the circuit in the circuit board from external interference (strong electromagnetic area or vulnerable area).
