Title:
TEST FIXTURE ADAPTER BOARD AND MEMORY TEST DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/048286
Kind Code:
A1
Abstract:
A test fixture adapter board and a memory test device, the test fixture adapter board comprising a circuit board, and a first connection part, second connection part, plurality of capacitors and capacitor switching circuit that are provided on the circuit board. The first connection part is plugged into gold fingers of a memory test fixture, and the second connection part is plugged into a slot of a memory to be tested, so that the memory test fixture performs power supply testing on the memory by means of a connection line of the circuit board. In addition, before power supply testing is performed on the memory, the capacitor switching circuit connects to a power supply thereof a capacitor that meets power supply requirements of a capacitor to be connected to a power supply of the memory so as to meet power supply test conditions of the memory. Hence, in the present application, the capacitor is provided on a low-cost adapter board, thereby reducing reworking and damage costs of the capacitor. Moreover by means of the capacitor switching circuit, the present application may flexibly select the capacitor connected to the power supply of the memory, thereby improving the service life of the test fixture adapter board and the test efficiency of the memory.
