The YCS iSocket Motherboard Test Fixture is a professional-grade diagnostic tool specifically engineered for testing the middle layer of iPhone X series mainboards after layer separation . This precision fixture allows technicians to quickly detect logic board faults without the need for complex jumper wires or guesswork, dramatically reducing diagnostic time for sandwich-style motherboards.

iPhone X motherboards utilize a layered construction where the upper and lower PCBs are bonded together. When troubleshooting issues such as power failure, no boot, or baseband problems, technicians must separate these layers to isolate the fault. The YCS iSocket provides a stable, accurate testing platform that connects to both the upper and lower layers simultaneously, enabling comprehensive diagnostics with a DC power supply .

Key Features

• Precision Middle Layer Testing – Specifically engineered to test the connection points between upper and lower layers of iPhone X series mainboards, allowing technicians to isolate faults after layer separation
