The 923665-28 is a surface-mount Test Clip with headless head. This series provides downsized series made of smaller components and higher densities. Now hard to access surface-mount ICs can be connected to test probes and logical assemblies quickly and easily without the risk of shorting out clips or damaging other board components. The 3M clips allow safe, accurate and convenient testing of plastic leaded chip carrier (PLCC) and ceramic leadless chip carrier (LCC) style integrated circuits. The unique action wedge design of the test clip allows all four of its side to open simultaneously for one step, secure attachment to the PLCC being tested.
