The ideal storage temperature of FFC flexible cable is 12~28 ℃, and the storage humidity is 30~60RH%. The shelf life of tinned conductor FFC flexible flat wire is 12 months, and that of gold-plated conductor FFC flexible flat wire is 6 months.

2、 FFC flexible cable is widely used

FFC is widely used in automobile airbag, security monitoring camera, scanner, notebook, LCD TV, display, fax machine, printer, digital camera, POS machine, video recorder, attendance machine, etc. Because of its small size, high precision, good flexibility, flexible use, easier welding and other characteristics.

3、 Applicable scope of FFC flexible cable

It is applicable to all kinds of horizontal connector with spacing of 0.5mm, 0.8mm, 1.0mm, 1.25mm, 1.27mm, 2.54mm, flip down connector, vertical connector, straight connector, bent connector, single-sided connector, double-sided connector, etc.

4、 Electrical performance of FFC flexible flat cable

1. Insulation resistance: measure the insulation resistance between adjacent conductors of FFC flexible cable or between conductors and ground under DC 500V, which is greater than 1000M Ω.

2. Withstand voltage: the FFC flexible cable is applied with AC 500V, 5mA voltage between adjacent conductors or between conductors and the ground for 1 minute without breakdown.

3. Current withstand: 0.5pitch FFC flexible flat cable, general current withstand ≥ 0.5A; 1.0pitch FFC flexible flat cable, general current resistance ≥ 1A.

5、 Mechanical properties

1. 180 ° zigzag resistance: zigzag once every time, conductor thickness 0.035mm, more than 30 cycles; The conductor thickness is 0.05mm, more than 20 cycles, and then measured and observed, without damage, meeting the electrical performance requirements.
