QianLi iBridge PCBA FPC Testing Cable for iPhone 6 6Plus 6S 6S Plus 7 7 Plus Front Camera Rear Camera Dock Connector Display Touch Motherboard Fault Checking
iBridge FPC Testing Cable for Display Touch FPC / Front Rear Camera FPC / Dock Connector FPC / Fingerprint Touch 3D FPC.
Great product for the phone board layout is precise and compact, and most PIN pins have no epitaxial line of testing. For example, the board does not connect to the LCD screen. When the boot board can not detect the screen, there will not be relevant voltage output and technicians can not detect and test the voltage value of the relevant circuit.
Each model have 4 type test cable as: rear camera, front facing camera,dock connector and touch screen cable.
Connect the connector on one end of the FPC measure cable to the corresponding connector on the phone motherboard, and use the external components or components of the motherboard (such as camera, display, battery, tail plug etc., all of which can be connected to the FPC connector on the motherboard).
Then connect to the connector on the other end of the FPC, and print the test pomts of all FPC interfaces in the form of laser printing or ink jet on the FPC, and mark the parameters and pins on the test points.
When the failure device is in the power off state, the multimeter can be used to measure the resistance parameter of the test point on the FPC connector. By comparing with the resjstanct parameter of the normal device, the abnormal test point will be found out, and the data of abnormal test point is analyzed to judge the fault coverage.
