PCB Contract Board Testing

PCB Board Testing

You need to test your printed circuit boards (PCB) but you don’t have the time, the staff or the equipment to do so? Don’t worry, we can do it for you! Whether your PCB is at prototype stage or being produced in small to medium quantities.

You don’t have to invest time and money into training your staff and/or buying the right equipment, because we have already done that for you!

Just send us your PCB design and/or the finished PCB’s and we will take care of the rest!

Integration of Boundary Scan (JTAG).
Fully detailed error report in .pdf or paper format.
Statistical Analysis.

Functional Testing

Functional testing is a testing method to as the name already implies, tests the function of a PCB. The functions are tested by feeding the PCB a predefined input and examining the output values. These values can be compared to what is expected and if they fit within the pre-set parameters.

Pro’s

Fast
Cheap
Tests if functions are working

Con’s

Doesn’t detect all failures
Doesn’t test individual components
Doesn’t test active components

In-Circuit Testing (ICT)

In-Circuit testing is a probing test which will test individual components on the printed circuit board. This can be done through a bed of nails type test fixture or through a fixtureless test setup (Flying Probe).

Fixture Testing

Fixture testing is best suited for stable products (don’t change in design often) and higher volume production.

Pro’s

Fastest
Can detect errors on individual component level
Can test passive and active components

Con’s

Fixture needed
Limited test coverage if PCB design didn’t take into account design for testing
Hard to adjust if PCB changes. The hardware (fixture) has to be edited

Flying Probe Testing

Flying probe testing is best suited for new product introduction (NPI), prototyping, PCB’s that change often in design and small to medium volume productions.

Pro’s

No fixture needed
Can detect errors on individual component level
Can test passive and active components
Easy to adjust if PCB changes. Software can easily be edited or automatically generated by CAD data.

Con’s

Limited test coverage if PCB design didn’t take into account design for testing
Number of components on PCB defines the total test time (more components means longer test time)
