Seeed PCBA Functional Testing
Seeed Fusion offers Functional Testing (FCT) and other testing and programming services for PCB assembly orders. Performed after assembly and general inspections, functional testing is a surefire way of ensuring all boards coming off the production line work as intended.
While Seeed will follow international assembly and quality control guidelines to maximize yield, as with any manufacturing process, there is always the potential for failures. Even more so with small batch or prototype assembly on a mixed line. As such, it is common to employ a functional testing program to isolate defective boards, whether the problem is incorrectly placed parts, failed joints or defective components - defects which may be difficult or impossible to catch with visual inspection alone.
Functional testing can be anything from a simple power-on test, point to point voltage testing, to running test firmware with custom-made jigs. Our lines are equipped with the essentials such as multimeters and function generators but Seeed also has the capability to develop test jigs and perform more advanced testing protocols. Please see the table below for more details.
To add functional testing to your order, just select Functional Test in the PCBA section of the order page and upload your test materials. Our engineers will update the quotation accordingly based on labor costs and any additional equipment costs if necessary. Don't have a test plan ready yet? You can also upload a test plan later in your shopping cart. Then just wait for the engineers to update the quotation.
Example simple test plan:
1) Apply 9.9V to the contacts as shown.
2) One LED should light up.
3) Change the voltage to 12.6V and press the button once.
4) Five LEDs should light up.
