Our Low Volume PCBA Assembly Services

Comprehensive assembly solutions tailored for prototypes and small production runs, from single boards to a few hundred units.

Prototype PCB Assembly

Rapidly assemble early-stage prototypes using SMT and THT technologies built to your Gerber files and BOM. Ideal for design verification, debugging, and fast iteration cycles before committing to production.

Low Volume PCB Assembly

Professional assembly for small-batch runs from 10 to a few hundred boards. Combines SMT and THT assembly, component procurement support, and strict quality control with flexible minimum order quantities.

Turnkey PCB Assembly

End-to-end assembly handling component sourcing, SMT/THT placement, soldering, testing, and final inspection. Eliminates vendor coordination so you can focus on product development and accelerate time-to-market.

Quick Turn PCB Assembly

Urgent prototype or small-batch builds delivered within 1–2 weeks without compromising precision. Transparent project communication and smart part substitution suggestions keep you on schedule and within budget.

Mixed SMT + THT Assembly

Handle complex boards combining surface mount and through-hole components in a single build. Automated placement and wave/selective soldering ensure reliability across mixed-technology designs of any complexity.

PCBA Functional Testing

Comprehensive post-assembly testing using custom functional test jigs, electrical testing, and performance verification to confirm every board meets your exact specifications before shipment.
