Independent semiconductor test interfaces
Precicon Engineering is an independent specialist for semiconductor test interfaces — contactors, sockets, DIBs, docking, and strip-test systems. Patent-backed design, delivered as documentation you own. Sockets built fast through qualified fabrication partners — or through your own supply chain. No equipment-vendor ties. No lock-in.
10 patents in test contactor, socket & interface design · Versatile DIB system designed for Infineon · Design experience across major IDMs and OSATs

The gap
The equipment vendor proposes solutions tuned to their own hardware — on their timeline, with their IP terms. The socket catalog doesn't have your package, your pitch, or your temperature range. Your internal team is stretched keeping the floor running. And the one independent engineering firm the industry trusted was acquired by an equipment manufacturer.
Meanwhile: yield is drifting on a contacting problem, the new package has no socket, or the ramp is stalling on an interface nobody has bandwidth to solve properly. That gap — between vendor lock-in and internal overload — is exactly where we work.
Two ways to work with us
Exploded-view render — interface design package contents
Asset to be produced — see Visual Asset Plan
Root-cause diagnostics and complete custom design packages for test interfaces: contactors, DIBs, docking, strip-test, thermal. Delivered as CAD, BOMs, and integration documentation you own outright.

Asset to be produced — see Visual Asset Plan
Application-specific test and burn-in sockets — fine-pitch, high-current, high-temperature, Kelvin — designed by a 10-patent socket inventor and built through qualified fabrication partners in Singapore. Or take the design package and build it yourself.

Why us
For decades the industry had one trusted independent test engineering firm — until an equipment manufacturer acquired it. That independence mattered: solutions chosen on merit, IP that stayed protected, no hardware agenda steering the advice.
We're built on that principle, with one addition the old model never offered: when you need a finished socket, we can deliver one — through fabrication partners we've qualified, not a captive factory with a lock-in agenda. And because you receive the complete design package with every build, you're never dependent on us for the next order.

How it works
A short technical call — engineer to engineer. For sockets: send the package spec and receive a feasibility answer within days.
Complete mechanical design with review cycles. Diagnostics run two weeks; design packages typically six to eight; socket designs usually faster.
Take delivery of the built sockets, the complete design package, or both. Manufacture anywhere, forever, without us.

Where to start
Design path
Two weeks, fixed fee, scoped before you commit. Root cause + design alternatives + effort estimates. The fee is fully credited toward the follow-on project — and covered by a money-back guarantee if it doesn't add value.

Send your package spec — outline, pitch, pin count, temperature range, volumes. Feasibility assessment and budgetary quote, free, within 5 business days.
Request a Socket QuoteFAQ
A package with no socket, a yield problem with no root cause, or an interface nobody has time to design — bring it to the engineer who'll actually solve it. First conversation is free and technical.
