Engineering Review Before Quotation

Before preparing a PCB assembly quotation, our engineering team reviews available project information to evaluate manufacturability, component sourcing conditions and production requirements.

This review helps identify potential manufacturing and supply-chain risks that may affect project schedules, sourcing strategies and production readiness.

Engineering Review May Include:

✓ BOM Verification & Component Availability Assessment

✓ Long Lead-Time, Allocation & Obsolescence Review

✓ Alternate Component Evaluation

✓ PCB Manufacturability & Panelization Review

✓ SMT, THT & Test Requirement Assessment

✓ Prototype, NPI & Production Planning Considerations

✓ Supply Chain & Schedule Risk Evaluation


Why Engineering Review Matters

Many sourcing, manufacturability and production challenges originate during product development rather than during PCB assembly itself.

Early engineering review can help identify component availability risks, manufacturability concerns and documentation gaps before materials are ordered and production schedules are finalized.

Addressing these factors earlier can help reduce sourcing delays, improve manufacturing readiness and support a smoother transition from prototype builds to production.


PCB Assembly Inspection & Quality Control

Quality verification is integrated throughout the manufacturing process to support assembly consistency, traceability and long-term product reliability. 

✓ SPI (Solder Paste Inspection)

✓ AOI (Automated Optical Inspection)

✓ X-Ray Inspection

✓ ICT (In-Circuit Testing)

✓ Functional Testing (FCT)

✓ IPC-A-610 Workmanship Standards

✓ Incoming Material Verification

✓ Process Traceability Controls

✓ ESD & Moisture-Sensitive Component Handling
