Receptacle Body Material Selection

RST receptacle products are unsurpassed for quality and reliability. We employ high performance plastics for the isolator base, with several material options available to cover any mechanical or environmental concerns. Mill-Max receptacle pins are used for the receptacle contacts. We manufacture each receptacle using state-of the-art fabrication techniques and CNC machines on-site in our privately owned machine shop.

Each receptacle has a thick isolator base that bolsters against the DUT board during installation. "Clean-out" areas are machined underneath the base around the receptacle pins to prevent pin-to-pin leakage from solder or flux residue that could otherwise remain after assembly.

Each individual receptacle part number is designed with distinct features to accommodate the unique characteristics of each socket. For example, if the socket has staggered tail lengths, our receptacle pins are set at staggered depths to ensure proper mating of the contacts.

The receptacle contacts of each part number are chosen based upon guiding principles of socket tail dimensions, insertion force, and user friendliness. Optional receptacle plating finishes are available to our customers to accommodate RoHS environments or other specific applications.

Each isolator base is machined and assembled in our factory to exacting specifications providing you the assurance that the socket receptacle combination will be a matched fit.

RST MAKES A RECEPTACLE FOR NEARLY EVERY SOCKET

Our standard receptacles have two basic configurations:  

1. Rectangular outline that shadows the socket footprint. 
2. Notched corner outline to use with an auto-handler docking plate.

The two basic receptacle configurations are illustrated in photos below in top and bottom views. The bottom view demonstrates the “bolstering” features machined into the underside of each receptacle.

Our standard receptacles also come in a variety of shapes to accommodate each socket type. The samples below illustrate several of the many different “standard” configurations that we produce on a regular basis:

QFP – Nearly all configurations depopulated to your lead count	QFN, to fit all socket configurations with or without center ground pin	SOIC, to fit all configurations	BGA, See separate BGA Page
PGA, to fit all socket configurations	Small SMD and SOIC configurations  including Kelvin test	Strip Connectors – Most configurations	Staggered pin length configurations
