Test pins are available with a variety of different heads, depending on the type of pad, solder joint or component pin they are to make contact with.
For the Macaos Integrated Test Jig, the desired head must be specified for each test point. The jig is supplied assembled, with pins inserted into receptacles, which may then be soldered to the test circuitry PCB.
