PCB E-Test is shortening of electrical Test.
E-Test is very important for PCB,
Because of only the PCB passed E-Test, PCB could be 100% usable.
All PCB Andwin made are passed E-Test before Final quality Control.
E-Test process could ensure all PCB are no short or open before delivery to customers,
How many test way of PCB E-TEST?
There are 2 ways in PCB E-test process
- Fly probe testingTested by fly probe testing machine.
Flying probe testing is slowly, it test PCB connect Net one by one.
Time is long, General cost 1-3 min or more. For 1 PCS.
- Low cost
- Do not need to make fix test tooling
- Low lead time for PCB prototype.
This type of PCB testing is suitable for PCB prototype,small batch order.
- Fix tooling testingThis test way means PCB are tested by Fixture testing machine.
Time is short for 1 PCS or panel,always in 5-10 sec.
But need to make a test fixture for each kind PCB.
It is not economical for PCB prototype,so, Fix tooling testing is suitable for
Mass production order.Pcb e-test fixture could be reused for repeat order.
