Final test injection moulded housing with heatsink

Customised for final functional testing of electronics preassembled into injection moulded housings with aluminium heatsinks. Built on the standard M4430 mechanical base, this fixture delivers repeatable probe contact, high signal integrity, and precise alignment for production testing.

Key Features & Technical Highlights:

• Stress-Free Clamping: Custom nesting holds the plastic housing securely without deforming the enclosure or internal PCB. 

• Tolerance Compensation: Absorbs stack-up variances between the PCB and housing to guarantee uniform contact pressure across all test points. 

• Heatsink Clearance: Engineered around the physical profile and thermal mass of integrated aluminium heatsinks. 

• Robust Signal Integrity: Utilising premium spring-loaded test probes (POGO pins) wired via short, optimised signal paths. 

• ESD-Safe Construction: Static-dissipative materials protect sensitive onboard circuitry during loading and testing. 

• Linear Actuation: Smooth vertical compression prevents uneven probe wear and extends fixture lifespan. 

Applications:

Ideal for electronics, industrial control units, IoT gateways, and power electronics where PCBs are mounted within final enclosures before end-of-line (EOL) testing.
