1. The fifth generation FFC flat cable design full coverage shield, soft and , ultra-thin thickness of only 0.5mm. 2. the use of 1.5mm aluminum alloy gasket reinforcement, to broken and dropped line problems, , can effectively block interference and noise. 3. connected with 12V power supply, send power adapter cable. 4. Add 0.8mm fixed plate to prevent PCB deformation and bending, which can extend the service life of PCB board and save hardware replacement cost. 5. Four-layer PCB board, gold finger fully gold-plated 10µ", good electrical conductivity, can reduce the oxidation rust impedance caused by the blue screen of death problem.
