We provide the following services
- Test Planning
- Board Bring Up
- Part Programming
- Functional Testing
- Custom Test Jig Development
- Failure Analysis
We can help you during any stage of your process!
PROTOTYPING
First stage of the PCB, proof of concept. Focused on functionality and demonstrable product. Board bring up and debug straight off the assembly line.
- Shorts and open test on voltage rails
- Basic confirmation of functionality & 'Board Bring Up'
- Basic power test supplies for stability and spec
- Measure clocks & oscillators
- If firmware available, program devices
- Start test jig spec during this phase
REV A
Fix the first issues identified in Prototyping stage. Additional features check. Expand areas of test.
- Program devices
- Unblock functionality test
- AC and DC measurement
- Jitter & accuracy
- Run diagnostics if available
- Basic environmental tests
- Jig development starts during this phase
REV B
Expanded test procedures to include reliability testing at temperatures to accelerate life time testing Pilot Functional Testing.
- Program devices
- Unblock functionality test with some boards
- AC and DC measurement with some boards
- Jitter &accuracy with some boards
- Run diagnostics with some boards
- Test jig development occurs during this phase
RAMP
Once production has been approved product starts to ramp up Test jig is fully developed and ready for volume production.
- Program devices
- Perform pass/fail testing
- Run diagnostics on jig with some boards
- Deploy test jig
- Deploy Functional Test
HIGH VOLUME
Failure analysis is an ongoing process throughout which ensures continuous improvements and yield.
- Start using test jig
- Run diagnostics jig randomly pull and test some boards
- Run Functional Test
