Quality & Engineering

Quality isn't a final check. It's the process.

Nine practices that run through every order, from the first design review to the board that ships -- not a certificate framed on a wall.

Held Certifications

Audited, not self-declared

Four certifications, each covering a different part of the quality system -- general quality management, automotive-sector requirements, product safety, and assembly-class reliability.

ISO 9001

International standard for quality management systems.

IATF 16949

Automotive-sector quality management requirement, built on ISO 9001.

UL Certified

Independent safety certification recognized across North America.

IPC Class 2/3

Industry acceptability standards for electronic assemblies, up to high-reliability class 3.

How It Works

Nine practices, one process

General descriptions of how each practice is applied -- not a list of equipment or instruments, since we're not going to claim tools we haven't confirmed.

01

Engineering Review

Every incoming design is reviewed against its stated specification before it enters the fabrication queue -- checking that what was ordered is what will be built.

02

DFM

Design-for-manufacture analysis flags manufacturability issues -- trace geometry, hole sizing, annular ring -- before fabrication starts, not after a board fails.

03

Process Control

Fabrication parameters are monitored at each stage of the process, so a deviation gets caught at the step it happens rather than at final inspection.

04

Material Control

Incoming laminate, copper foil and other materials are checked against the specification called for by the order before they enter production.

05

Inspection

Automated optical inspection checks pattern accuracy, spacing and copper integrity -- a defect in the copper pattern gets caught before the board moves further down the line.

06

Testing

Every board is electrically tested for continuity and isolation across its nets before it ships -- not a sample of the run, the board itself.

07

Traceability

Production records connect a finished board back to its work order, so a question about a specific batch can be answered specifically, not approximately.

08

Reliability

Boards are built to meet the acceptability criteria defined by IPC Class 2/3 -- the industry standard for reliability-critical electronic assemblies.

09

Continuous Improvement

ISO 9001 certification requires an ongoing corrective-action and process-improvement system, not a one-time audit -- quality management is reviewed on a continuing basis, not treated as a fixed checklist.
