IPC

IPC-A-610 Compliance

All assemblies produced and inspected per IPC-A-610 Class II/III — the globally accepted benchmark for electronic assembly acceptability and workmanship.
AOI

Automated Optical Inspection

Post-reflow AOI scans every joint — detecting solder bridges, insufficient solder, misalignment, missing components, and lifted leads with high-resolution cameras.
ICT

In-Circuit & Functional Testing

Electrical validation ensures every net is connected, every component is functional, and the board performs to specification before it leaves our facility.
DFM

Design For Manufacturability

Early-stage DFM review catches design issues before they become production defects — improving first-pass yield and reducing your overall programme cost significantly.
