QianLi ToolPlus iBridge PCBA FPC Test Cable for iphone 6 6S 7 Plus Motherboard Fault Checking, New Diagnosis Solutions for iphone 6 6S 7 Motherboard Failure, iBridge FPC Testing Cable for Display Touch FPC / Front Rear Camera FPC / Dock Connector FPC / Fingerprint Touch 3D FPC.
QianLi iBridge FPC Test Cable for iphone 6 6S 7 Motherboard Fault Checking
The iphone Motherboard 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.
This iBridge FPC Test Cable for iphone 6/6p/6s/6sp/7/7p Motherboard Fault Checking, every model have 4 type FPC test cable as: Display Touch FPC / Front Rear Camera FPC / Dock Connector FPC / Fingerprint Touch 3D FPC.
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.
