Testing

Functional & Environmental Testing

Units ship plug-and-play. Testing criteria are agreed with you in writing before production, and every unit ships against that checklist — not a sample, every unit.

The funnel

Defects get caught where they're cheapest to fix.

01

AOI at board level

Automated optical inspection on the partner SMT line catches placement and solder defects before a board ever reaches integration.

02

Functional test with your firmware

The assembled unit runs your code against test criteria agreed with you in writing — real inputs, real outputs, not a power-on smoke check.

03

Ingress & sealing validation

Where the build carries an IP rating, the sealed assembly is validated against it before shipment.

04

OQC & documentation

Outgoing QC on AQL sampling, and the inspection report ships with the goods.

Additional test capability (burn-in, thermal cycling, ICT) is program-specific — raise it in the RFQ and you'll get a straight answer on what the assigned production line can and cannot run.

Put the checklist in writing before the first unit ships.

Send your test requirements with the data package — the Go/No-Go criteria come back as part of the quote, agreed before production starts.
