Our PCB Prototype and Assembly Services

Integrated PCB prototype, design, fabrication, assembly, inspection, and testing services for faster product development.

PCB Assembly

Quick-turn PCBA services for engineering validation, including SMT, through-hole, mixed-technology, fine-pitch, BGA, hand-solder, RoHS-compliant, conformal coating, and potting requirements.

PCB Design

Immediate-response schematic capture, PCB layout, DFM, DFT, component sourcing consultation, and design packages optimized for fabrication, assembly, testing, and production readiness.

Prototype Fabrication

Fast prototype fabrication support designed to reduce NPI time, validate manufacturability, and create a smoother handoff from early engineering boards to repeatable production builds.

Prototype To Production

Faster Boards With Single-Source Control

SBC helps engineering and procurement teams compress the path from design files to assembled boards. With design support, quick-turn fabrication, PCBA assembly, inspection, testing, and production options under one source, customers gain tighter process control, fewer delays, and clearer accountability from first prototype through scalable manufacturing.
