Incoming Inspection
Before production, we check the identity, condition and required documents for the PCBs, components and materials specified for your order.
Quality Requirements Before Production
PCB & PCBA Quality Inspection From Incoming Materials to Shipment
Before quotation, send your production files, inspection requirements, acceptance criteria and required records. EBest PCBA will review the applicable checks for incoming materials, first articles, production, testing and shipment, and confirm the included requirements in the quotation.

Quality Checks During Production
5 Quality Checks From Incoming Materials to Shipment
We review the required checks for incoming materials, first articles, production, inspection and shipment. The quotation will state which checks apply to your order based on your files and quality requirements.
First Article Check
When first-article approval is required, we check placement, polarity, orientation, workmanship and other agreed build details before the remaining batch continues.
In-Process Inspection
During PCB fabrication and PCBA assembly, we perform the agreed inspections to identify issues before they affect additional units.
Inspection and Testing
We use the visual, SPI, AOI, X-ray, electrical or functional checks included in the quotation when they are suitable for the product and the required test inputs are available.
Shipment Check
Before shipment, we verify the finished quantity, workmanship, completed tests, packaging and required delivery records.
The quotation will confirm the required inspection and test methods based on the PCB construction, component packages, assembly process, test access and your acceptance criteria.
Inspection Method Selection
How We Select Inspection and Test Methods for Your PCB or PCBA
Tell us which defects, acceptance criteria and result records are important when you send your files for review. We review the board design, component packages and test access to confirm the suitable inspection or test methods.

Quality Records Available for Your PCB or PCBA Order
Send us your requirements for inspection, test and traceability records, including the file format, retention period and delivery timing. We will confirm what can be provided in the quotation.
Inspection and Test Records
Depending on the quotation, available records may include first-article, AOI, X-ray, visual inspection or test results.
Batch and Serial Number Traceability
When required, batch or serial numbers can link material or component information with production status and inspection records for your order.
Shipment Records
Before shipment, we verify the inspection and test status, finished quantity, packaging and the delivery records agreed for the order.
When a Quality Issue Is Found
How We Handle Materials or Assemblies That Do Not Meet Requirements
We stop the affected work, separate the affected materials or assemblies, record the issue and confirm the required action before production continues.
01
Identify and Separate Affected Items
We record the issue and separate the affected materials or assemblies from other work.
02
Check the Affected Quantity and Requirement
We identify the affected lot or quantity, the production stage and the requirement that was not met.
03
Confirm the Required Action
If deviation approval, rework, replacement or another customer decision is required, we ask for written confirmation before proceeding.
04
Complete the Action and Verify the Result
We complete the agreed action, inspect the result and record the outcome before work resumes or the products are prepared for shipment.
