Sof-Tek is a custom PCB design company providing end-to-end PCB design & manufacturing services for industrial, automation, and embedded control applications. We design custom printed circuit boards (PCBs) using proprietary firmware to support multiple communication protocols, complex logic, and third-party component integration.
Our USA-based, in-house Altium design team works directly with your engineers to deliver reliable, production-ready boards — from prototyping through full-scale manufacturing. Whether you’re replacing a legacy control panel, reducing wiring complexity, or developing a new product, our custom PCB design services reduce error, footprint, and build time compared to traditional control assemblies.

As a full-service PCB design firm and manufacturer in Northern California, Sof-Tek specializes in:

Requirements & Review
We work with you to find the best solution based on your application, schematics, environmental needs, and performance goals.
PCB Design & Layout
Our PCB layout design service uses Altium to develop optimized board layouts that integrate multiple components and communication protocols while minimizing footprint and wiring complexity.
Fabrication & Wiring
Control panels are assembled, labeled, and wired with precision and consistent standards.
Prototyping & Reverse Engineering
We develop prototypes or take inspiration from obsolete PCBs to modernize performance, reduce size, and support non-standard and third-party components.
Assembly & Production
Every board undergoes functional testing of I/O, digital inputs/outputs, and communications to ensure reliability in real-world environments.
Testing & Validation
With 20,000 sq ft of in-house production capacity, we support everything from short-run prototypes to 5,000+ copy-exact units using streamlined, quality-controlled manufacturing processes.
We manufacture through-hole PCBs in-house
We can do through-hole PCBs in-house and can work with you or your partners for manufacture of surface mount PCBs.
