FFC technical knowledge
FFC technical parameters:
Conductor number n: the number of copper conductors in the row wire;Distance P: the distance between the center lines of two adjacent conductors;
Edge distance M: the distance between the center line of the outermost conductor and the edge of the row line:
Full spacing TP: the distance between the centerlines of the two outermost conductors, TP = P * (n-1);
Total width W: the distance between the two edges of the cable, w = P * (n + 1);
Total length TL: the distance between the two ends of the cable;
Insertion thickness TT: the thickness of two connecting ends of the flat wire;
The 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 plate is cross pasted on the insulating tape 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 on the conductor directly;
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 adhesive paper, and the internal half is peeled off;
Type G: solder both ends directly.
FFC characteristics:
1. Miniaturization, small size and space saving;
2. Simplify wiring mode, simple connection and save material cost;
3. Flexible, flexible and foldable.
FFC specifications:
1. Spacing: 0.5mm 1.0mm 1.25mm 2.0mm 2.54mm
2. Length: 15mm ~ any
3. Type: A, B, C, D, e, F, G, h, I, J, K
FFC special processing:
1. According to the customer's needs, it can be folded, divided, terminal and other special production;
2. EMI countermeasures: cutting ground wire, silver paste, aluminum foil, copper foil, silver foil, conductive cloth, acetic acid cloth, Myra, etc.
3. It can be used in TFT-LCD to replace the traditional wire harness
