Industries Served

Where the work
ends up.

Space

Mission-ready. Built to spec, every spec. IPC & J-STD space addendum compliant.

Aerospace / Defense

ISO 9001, J-STD & IPC compliant.

Medical / Industrial

Electro-mechanical box builds for diagnostic and industrial equipment that can't fail in the field.

Why 603

What we do different.

Quality is the product

Every assembly is built to AS9100 discipline, 100% continuity checked, and fully traceable. We don't talk about quality, we document it on every unit that ships.

Work instructions before we build

Nothing hits the bench until the process is written down. NPI review, build notes, and test steps are locked in up front, so the first article looks like the thousandth.

Quick-turn with no surprises

Prototypes in days, not months, without the missed specs, rework loops, or schedule slips that usually come with speed. The process is set up to move fast, not to cut corners.
