United Innovative Solutions – PCB Assembly
PCB Assembly Services
UIS is capable of two types of printed circuit board assembly services. They are full and partial turn-key services.
Full Turn-Key covers all aspects of PCB fabrication and assembly, including manufacture of PCBs, parts procurement, tracking of online orders, quality inspections, and final PCB assembly.
In Partial Turn-Key, the customer is responsible for supplying the PCBs and a partial list of parts. UIS will order the remaining parts and perform the assembly according to the customer’s requirements. We can also kit the parts.

How We Test Our Final Automated Circuit Assemblies
UIS uses a variety of testing methodologies to ensure the assembled boards are functional prior to shipping. They are:
- Basic Quality Test: visual inspection.
- X-ray Inspection: tests for BGAs, QFN and bare PCBs.
- AOI Checks: tests for solder paste, 0201 components, missing components and polarity.
- ICT (In-Circuit Test) / Functional test: according to the customer’s testing procedures.
ISO 9001 Quality Certification
