01
Documented acceptance criteria
Turn product expectations into steps and observable pass/fail results that can be repeated across the batch.
// FUNCTIONAL TESTING
PCBA Functional Testing Before Your Boards Ship
Move beyond visual inspection by checking assembled boards against a repeatable test procedure, expected signals, firmware, and pass/fail criteria that you define.
ENGINEERING FILE REVIEWPROTOTYPE & SMALL BATCHWORLDWIDE DELIVERY
// SERVICE OVERVIEW
Test the behavior that matters to your product
Functional testing is quoted after the procedure and required resources are reviewed. A useful test package explains how to power the board, load firmware, connect fixtures or peripherals, run each check, and decide whether the result passes.
02
Pre-shipment issue detection
Identify power, programming, communication, interface, or functional problems before boards are packed and shipped.
03
Remote engineering coordination
For complex validation, the test method and results can be reviewed with your engineering team before release.
// HOW TO START
A clear handoff for a faster review
Project workflow
Review the test specification and required resources
Confirm firmware, connections, fixtures, and expected results
Run the agreed procedure on the assembled boards
Record the outcome and resolve exceptions before shipment
What to send
- Step-by-step test specification
- Power requirements, firmware, and programming instructions
- Expected readings, outputs, or user-interface behavior
- Required fixtures, cables, loads, peripherals, or remote access details
// COMMON QUESTIONS
FUNCTIONAL TESTING FAQ
Is functional testing the same as AOI?
No. AOI checks visible assembly features, while functional testing powers or operates the board to evaluate defined behavior.
Who creates the test procedure?
The customer should provide the product-specific requirements and acceptance criteria. PCBAForge reviews the procedure for repeatability and production use.
Can you test only part of the function?
Yes. The scope can focus on critical power rails, programming, communications, interfaces, or another clearly defined subset.
