QianLi iSocket 13 Features

• Double-ended spring contacts support alignment between the board layers and pinboard.
• BeCu spring probes provide the contact interface used in the existing product configuration.

• Fastening buckles hold the stacked assembly during suitable bench tests.
• A compact layout allows inspection alongside the workshop’s diagnostic equipment.

How to Prepare the Fixture

Identify the board model and inspect both the motherboard and contact pins. Choose the correct pinboard and any required spacer. Place the lower board on its locating points, align the pinboard, then position the upper board and close the frame without forcing the assembly.

Connect only the compatible display, power lead and test accessories required by your diagnostic procedure. Switch off the power before moving or removing the board. If the frame does not close naturally, stop and check the alignment rather than applying additional pressure.

Choosing the Right Series

This listing covers the 13 Series fixture. Similar-looking iSocket products for other generations are separate items. Board layout, pinboard compatibility and regional variants must match the device being serviced. Contact GSM Kart if the board markings or package configuration are unclear.

Frequently Asked Questions

Does the fixture repair a faulty board automatically?
No. It provides a physical connection for diagnosis. A trained technician must interpret the test results and perform the required component repair.

Are phones and other bench equipment included?
Phones, customer motherboards, microscopes, displays and power supplies shown in application photos are not included unless specifically stated in the package configuration.

Can I use another generation’s pinboard?
Do not assume compatibility from appearance. Select a pinboard intended for the exact fixture, board model and relevant regional version.
