Method for an on-board SMT device interface socket

Disclosed is a method for an on-board surface mount technology (SMT) device interface socket. Benefits include improved functionality, an improved test environment, and improved yield.

Background

� � � � � When SMT devices are mounted on the PCB, direct access must be available to each pin at the in-circuit test (ICT) fixture for testing, debugging, or programming. However, the ICT test platform only offers limited test resources.

� � � � � The conventional solution is to unsolder an SMT device from the printed circuit board (PCB) for further failure analysis. It is a very time consuming process and may induce damage to the device, such as bent pins or overheating. PCB pads or traces may become damaged due to improper or repeated unsoldering.

General description

        � � � � � The disclosed method is an interface socket for accessing SMT device pins directly on the PCB.

        � � � � � The key elements of the method include:

•        � � � � Vacuum concept to retain the disclosed method interface socket

•        � � � � Leaf spring pins

Advantages

        � � � � � The disclosed method provides advantages, including:

•        � � � � Improved functionality due to providing a universal and reusable socket across all types of device packages

•        � � � � Improved test environment due to providing a direct on-board pin access solution for SMT devices without using the ICT fixture

•        � � � � Improved test environment due to requiring no additional test points as required by the ICT f...
