Speaking ofFFC flexible flat cableThe characteristics of super flexibility, bending resistance and easy folding will flash into your mind. This is only one of the basic characteristics of FFC flexible flat cable. Let me comprehensively analyze the performance characteristics of FFC flexible flat cable.


1、 Storage environment of FFC flexible cable

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.

2. Bending resistance: the conductor thickness is less than 0.035mm, the bending radian is R15 ± 5mm, the sliding distance is 50mm, and the bending test is conducted for 1 million times at the speed of 500 times/min, without appearance damage, meeting the electrical performance requirements.

3. Abrasion resistance: R0.5mm, load 600 ± 5g, 60 times/min speed, 100 mm stroke horizontal friction test 10000 times, no damage in appearance, meeting the electrical performance requirements.

4. Peeling strength: the tensile testing machine carries out the peeling test at the speed of 25 ± 3mm/min. The test results show that the adhesion between the adhesive film and the conductor, the reinforcing plate and the conductor, and the adhesive film and the reinforcing plate are within the range of standard parameters.

5. Repeated plugging: use the appropriate FPC connector to plug and unplug 30 times at the speed of 10 times/minute, without damage to the appearance, meeting the electrical performance requirements.


6、 Environmental performance of FFC flexible cable

1. Heat resistance: store in air at 80 ± 2 ℃ for 96 hours, and then store at room temperature for 0.5-2 hours. No appearance damage, meeting the electrical performance requirements.

2. Damp-proof: put it in the air of 40 ± 2 ℃ and 90-95% relative humidity for 96 hours, and then return to the room temperature for 0.5-2 hours for measurement. No appearance damage, meeting the electrical performance requirements.

3. Cold resistance: put it in air at - 40 ± 2 ℃ for 96 hours, and then put it at room temperature for 0.5-2 hours. No appearance damage, meeting the electrical performance requirements.

4. Temperature periodicity: cycle 5 times under - 40 ± 2 ℃ 2H ->80 ± 2 ℃ 2H ->25 ± 2 ℃ 2H. No appearance damage, meeting the electrical performance requirements.

5. Salt spray: 35 ± 2 ℃, 5 ± 1% salt water spray, 24H gold plated Au spray, 12H tin plated Sn spray. After the test, wash with warm water at room temperature, and then dry at room temperature. No appearance damage, meeting the electrical performance requirements.
