What We Build.

From precision stamped components to hermetic package platforms, Sanjin supports RF, power, optoelectronic, and industrial semiconductor programs with product families and build-to-print parts.

How We Make It Reliable.

Reliable volume manufacturing starts before the first production lot. We work through tooling, material behavior, inspection plans, and process windows so complex parts can move from prototype approval to long-term supply.

Process Engineering

Designing for repeatable manufacturing.

Tooling, fixture design, manufacturability review, and process planning before parts enter volume production.

Material & Thermal Control

Controlling material behavior under stress.

Kovar, ceramics, glass, molding compounds, CTE behavior, sealing windows, and thermal expansion risk.

Quality Validation

Validating the process, not only the part.

FAI, AOI, SPC, dimensional inspection, hermeticity checks, and reliability testing for critical applications.

Scalable Production

Keeping approved parts consistent over time.

Lot-to-lot consistency, material control, qualified supply, and long-term readiness for high-volume programs.

High-volume output depends on process control, not chance.

The Human Element Behind the Precision.

True precision is sustained by experienced people, stable teams, and a culture that treats every micron as customer risk.

Sanjin reliability lab and engineering team

Built by people who understand what precision carries.

Since 1997, Sanjin has built its manufacturing culture around veteran toolmakers, engineers, and production teams who understand that complex semiconductor components cannot depend on automation alone.

From in-house tooling to long-term process ownership, our work is shaped by people who treat high-stakes customer programs as responsibilities, not transactions.
