Samtec Compliant Pin Termination Specifications

2022-10-21

●Samtec offers compliant pin leads, also known in the connector industry as press-fit leads, on select product series. The connector is terminated, or processed,by pressing it onto the printed circuit board (PCB). Such a lead is designed to create a gas tight interference fit with a properly sized plated-through-hole (PTH). This enables low temperature, solder-less processing for the connector. All Samtec compliant pin leads are "eye of the needle" geometries. Eye of the needle geometries have been utilized for over 30 years. Special tooling is required to terminate the connector, and it is referenced on the specific Samtec product's Print.
●Samtec compliant pin products are designed to work with a minimum thickness PCB. The minimum thickness is defined in the Product Specification or on the Footprint Drawing for that specific Samtec product. In the absence of a documented minimum PCB thickness, the default minimum PCB thickness is .062". It is not necessary for the "eye" to be centered in the PCB, only that it be seated to a certain depth. PCB thicknesses greater than the minimum are allowed as long as the PTH construction tolerances are held in the region in which the compliant geometry operates.
