Abstract
A test board for testing a packaged integrated circuit has a set of contacts matching counterpart contacts on a socket. The contacts are each connected to a first voltage plane containing power, a second voltage plane carrying ground, and a set of terminals that will be connected to a tester system. The number of terminals necessary to operate the circuit is identified, both power terminal and signal-carrying terminals to the affected part of the circuit, and two of the three connections to the contacts are severed; e.g. the terminal carrying signals is disconnected from the power and ground. The disconnect from the voltage planes may be performed by an automated milling machine in a short time, providing much faster turnaround than a method that forms a custom-made board.
