Our PCBA Functional Testing Process
Our structured testing workflow ensures precision, repeatability, and full traceability:
Requirements Review
-
The customer provides the functional specification, schematics, test procedure, firmware, interface information, reference sample, and acceptance criteria where available.
Test Plan Development
-
Testing steps, equipment, test points, operating conditions, pass/fail limits, and required production records are defined.
Fixture & Program Preparation
-
Required fixtures, cables, software, firmware, test interfaces, and reference equipment are prepared and verified.
Trial Testing
-
Sample PCBAs are tested to confirm the procedure, fixture connection, expected results, and acceptance limits before batch production.
Production Testing
-
PCBAs are tested according to the approved work instructions. Failed units are separated and recorded for review.
Results & Release
-
Test results are recorded according to project requirements, and accepted boards proceed to packaging or finished-product assembly.
Frequently Asked Questions
Get Expert Answers. Get Your Project Moving Faster
What information is required to develop a functional test?
Please provide the product specification, schematic, interface information, firmware, operating procedure, acceptance limits, and reference sample where available. Clear test requirements help us prepare a more accurate procedure and quotation.
What is the difference between ICT and functional testing?
ICT checks circuit-level conditions such as component presence, shorts, opens, and selected electrical values. Functional testing powers the PCBA and evaluates whether it performs the agreed product functions.
Can you develop a custom functional test fixture?
Yes, custom fixtures may be developed according to PCB test points, connectors, interfaces, quantities, and test requirements. Fixture cost and development time are evaluated separately.
Can you use our existing test procedure and fixture?
Yes. Customer-supplied procedures, software, fixtures, cables, and reference samples can be reviewed before production. Compatibility and operating requirements should be confirmed during project preparation.
