ECT’s comprehensive portfolio of receptacles offer flexibility in PCB test fixture design

ECT leverages its industry leading experience in probe and receptacle design and manufacture to provide cost-effective and reliable customer-focused solutions for the most challenging ICT and FT applications. ECT receptacles allow for rapid replacement of spring probes without disrupting wiring. ECT’s comprehensive offering of receptacles provides customers with fixture design flexibility that results in an optimal product for their customers.

ECT receptacles meet both commercial and technical challenges. PCB testing requires cost effective and reliable ICT and FT receptacle solutions that allow for the replacement of spring probes in fixtures without damaging the electrical connection to the test fixture. At the same time, a stable low resistance path through the probe/receptacle assembly must be maintained while withstanding a rugged mechanical environment.

ECT replaceable probes are retained by receptacles permanently fixed into a retention plate to which electrical connection is made. Typical probe retention is achieved by detents in the receptacle or a threaded connection. Removal of the probe does not damage or break the electrical connection to the retention plate and receptacles.
Receptacles are retained in the fixture retention plate by a press fit ring on the outer surface of the receptacles. Receptacle options from ECT include:

• Crimp receptacles (type W): This reliable connection is used primarily on smaller probe sizes in high density applications where wire wrap is not an option.
• Solder cup (type W-1): Used to attach the wire by soldering. It offers an excellent electrical connection between wire and receptacle.
• Wire wrapping (receptacles type W-2 and W-3): These are the preferred way of connecting wires to receptacles in higher volume fixtures as they are the least labor intensive. Wire-Wrap receptacles are available in 2 styles: square post and round post. Round post receptacles are mostly used if the connection will be made using a mating standard e.g. edge card connector.
• Fastite® Termination: Offers the lowest fixture wiring cost for 50 mil test center receptacles. The design combines a quick wire-insertion slot in the termination end with a precision-molded dielectric sleeve that reinforces the connection, eliminates strain and prevents electrical shorting.
