Étiquette : réparation de la carte logique de l'iphone

Mobile phone logic board repair is rather complicated. For one thing, the logic board is the printed circuit board, which allows communication between many crucial electronic components, and provides connectors for other peripheral. For another thing, all the electronic components are tiny and small, which makes the operation of motherboard repairing more difficult. Today we are going to introduce a new testing tool for logic board repair – iBridge PCBA testing cable, which including 4 parts: LCM and touches testing cable, front camera testing cable, rear camera testing cable and charging dock testing cable. Now It’s available for iPhone 6/6 Plus/6s/6s Plus/7/7 Plus models. Let’s check how this tool makes your repair and diagnosis more efficient.

It’s the extension connector on motherboard

When connecting iBridge to the logic board only, it is the extension connector on the motherboard. To measure diode value is a common way to check if the relevant components are open circuit. With the enlarged pins of connector on the cable, you can measure the diode value quickly and precisely. What’s more, the cable is marked with the reference diode value, which further saves your time in checking with schematic bitmap.

It’s the extension connector of parts

When connecting iBridge with parts only, it is extension connector of the corresponding parts. Take LCD screen measurement as an example. You can measure the diode value of each pin on the cable. By comparing it with the reference value marked on the cable, it’s very easy to confirm whether the LCD screen is faulty or not.

It’s the extended cable

When connecting iBridge to the motherboard, it can also be used as an extended test cable for parts testing. Take front/rear camera cable as examples. Connect one end of iBridge to motherboard, and another end with the parts to be tested. In this way, the connector on the logic board does not need to be hooked up again and again. Thus to prevent the connector on the logic board from wearing and tearing when testing the front and rear camera.

It’s the test point.

When connecting iBridge with both logic board and parts, it can be used as the enlarged testing point. Take the rear camera as an example. We can measure the working voltage of rear camera and check if it is normal by comparing the value with the reference voltage marked on the cable. So that the technicians can locate the faulty components of circuits on the logic board quickly and precisely.

Conclusion :

1. Time-saving with corresponding voltage reference value of key circuits marked on the cable.

2. Efficient measurement with corresponding reference diode value marked on the cable.

3. Used as extended testing cable to protect the connectors on the logic board.

4. Efficiently locate faulty components with all test points marked on the cable.

5. Enlarged pins on the cable make the operation much easier.

6. No microscope and schematic bitmap needed.
