Visual

Manual / Visual Inspection

Experienced PCB inspectors perform detailed visual inspections of every board

Identifies surface defects including scratches, cracks, and imperfections

Checks solder mask coverage, silkscreen quality, and surface finish

Complements automated testing — catches defects that machines may miss

Cross-Section

Microsections Inspection

PCB cross-section analysis for detailed internal examination

Identifies layer alignment issues and internal manufacturing defects

Checks copper plating quality, via fill, and barrel integrity

Uses optical microscopes and scanning electron microscopes (SEM)

Electrical

PCB Electrical Testing

Verifies electrical parameters including continuity and isolation

High-voltage dielectric strength testing

Resistance measurement for traces and vias

Uses specialized PCB testing equipment and custom fixtures

Automated

Automated Optical Inspection (AOI)

High-resolution camera systems scan every board automatically

Detects shorts, opens, missing pads, and surface defects

Compares against golden board reference for consistent results

100% coverage — every board inspected, not sampled

Bare Board

Bare Board Testing

Comprehensive testing of unpopulated PCBs before assembly

Verifies continuity and isolation between all circuits

Identifies manufacturing defects in traces, vias, and pads

100% electrical test on all production boards

Flying Probe

Flying Probe Test

Automated probe system tests circuits without expensive fixtures

Accesses any test point including fine-pitch and dense boards

Ideal for prototype and low-volume PCB testing

Fast setup — no fixture design or fabrication required

Impedance

Impedance Testing

Measures characteristic impedance of controlled-impedance traces

Ensures signal integrity requirements are met for high-speed designs

Critical for PCIe, DDR, RF, and high-frequency applications

Uses Time Domain Reflectometry (TDR) equipment with test coupons

Testing Process

Our PCB Testing Process

Analysis

Requirement Analysis

We review your PCB specifications, IPC class requirements, and testing needs to develop a customized testing plan before production begins.

Visual

Visual Inspection

Experienced inspectors perform detailed manual inspections to identify surface defects, workmanship issues, and obvious manufacturing problems.

Automated

AOI & Automated Testing

Advanced AOI systems scan every board for shorts, opens, and surface defects. 100% coverage with automated pass/fail reporting.

Electrical

Electrical Testing

Comprehensive electrical tests verify continuity, isolation, and dielectric strength. Flying probe or fixture-based testing depending on volume.

Impedance

Impedance Verification

TDR impedance testing on controlled-impedance boards. Test coupons measured and results documented against specification tolerances.

Certification

Quality Certification

Final quality assurance review and documentation. Test reports, certificates of conformance, and IPC inspection records provided with shipment.

Is 100% electrical testing standard?

Yes. All production PCBs receive 100% electrical testing (continuity and isolation). Flying probe is used for prototypes and low-volume; fixture-based testing for production runs.

Do you provide test reports?

Yes. Test reports, AOI results, and certificates of conformance are available on request. IPC-A-600 inspection records provided for orders requiring documentation.

What IPC class do you inspect to?

Standard inspection is IPC-A-600 Class 2. Class 3 inspection available on request for high-reliability applications. Specify your IPC class requirement when ordering.

SMT speed ≠ PCBA lead time. ⏱
The clock is usually set by materials/BOM, stencil prep, first-run tuning, inspection slots, rework handling, and final test.

At POE, we front-load checks and align these gates early—so builds flow from release → shipment without surprise delays. pic.twitter.com/H5ESaGgO0z
