Mijing C21 Pro Motherboard Layered Testing Fixture (iPhone 13 Series iSocket)

The Mijing C21 Pro is a professional-grade, solder-free diagnostic test stand equipped with custom gold-plated spring probes and high-precision CNC alignment machining. It is engineered to temporarily sandwich and interconnect split top and bottom logic boards, enabling technicians to fully test critical device functions—such as display, touch, cameras, Face ID, WiFi, and baseband signal—on the iPhone 13, 13 Mini, 13 Pro, and 13 Pro Max before permanently soldering the middle frames back together.
