Electrical Testing for Testing USB-C connector pins
UCD-340 for testing USB-C connectors
One of the most common manufacturing defects on USB-C devices such as smartphones are poorly soldered connector pins. The USB-C connector is capable of delivering and receiving up to 100W of power. For safety purposes, it is essential to test that the USB-C connector pins are properly soldered into the circuit board. A poorly manufactured USB-C connector can cause the cable or the device to overheat. This has known to cause the melting of the cable or serious overheating of the device causing terminal damage.
Unigraf USB-C test tools offer a unique solution for testing the connector pins. A built-in electrical test enables the testing of each connector pin. Thanks to a software-based cable flip, the electrical test enables testing of the USB-C connector with single cable insertion. In production, this saves valuable time as there is no need to insert the cable in both ways. The electrical test features ready-made tests for testing Vconn and Vbus voltage levels. All electrical tests can be automated for production line testing.
