In terms of their manufacturing, their lines are formed in different ways:

FPC is a kind of flexible circuit board with different single-sided, double-sided and multilayer structure, which is processed by FCCL (flexible copper-clad foil) by chemical etching
2 FFC uses two layers of insulating foil film with flat copper foil between them. The finished product is simple and thick
Naturally, FFC is much cheaper in terms of price. Considering the production cost, more enterprises prefer to use the relevant design of FFC
General specifications of FFC flexible cable industry:
P  ×  N  ×  TL  ×  TYPE  ×  (S1/S2 / S3/S4) (CT  ×  CW)

For example: 0.5 ×  forty-five ×  three hundred ×  A(4/4/8/8)(0.035  ×  0.30), which means 0.5mm spacing, 45 bits, total length of 300mm, in the same direction, 4mm at both ends, 8mm length of reinforcing plate. FFC flexible flat wire with copper wire specification of 0.035*0.30 is used, and this specification is mainly applicable to LCD.
Figure of FFC flexible flat cable model (type):
Common models are as follows:
Type A: both ends are connected and the reinforcing plate is pasted on the insulating tape;
Type B: the reinforcing plates are pasted on the insulating adhesive paper cross directly;
Type C: the reinforcing plates at both ends are directly pasted on the conductor;
Type D: the reinforcing plates at both ends are cross pasted directly on the conductor;
Type E: one end of the reinforcing plate is pasted on the insulating tape, and the other end is directly soldered;
Type F: the reinforcing plates at both ends are directly pasted on the insulating tape, and the inner half is peeled off;

Type G: solder directly at both ends.
