We hope the following will help and possibly improve your design. Like most other components are Pogo Pins heat resistant only up to a certain point. Wires connect with other wires or pins only if. 6. The tooling hole size determines whether the test fixture's PCB alignment pins can be placed on the same platen as the spring probes. This will enable you to keep the routing between pins short and wide, which is essential for reducing inductance. (See Figure 7) The PCB and connector assembly should be inspected from the back side of the PCB to ensure that the pin has properly entered the PCB and not buckled. PCB receptacles are female connectors. Pitch (mm): Mated Height (mm): Circuits: Current (MAX): 2. Using round pins allows more of the header contact to touch the PCB, thus allowing a high current rating. I'm a bot, bleep, bloop.
