Hi All,
We are manufacturers of bare PCBs.
We were conducting temperature cycling test as per
Condition B of JESD22-A104D (-55°C to +125°C). The
test requirement was for 500 cycles. This testing
was a part of qualification of PCBs for one of our
customer.
We have loaded a set of 4 bare PCBs and 4 assembled PCBs
(not powered on - loaded in passive mode after assembly)
in the thermal cycling chamber.
Now, 350 cycles are completed, but the thermal
cycling chamber has stopped due to some issue with
the thermal cycling equipment.
Now my question......... can the testing be continued
for another 150 cycles to complete 500 cycles OR
should the whole exercise be started from fabrication
of fresh PCBs, Assembly and do the temperature
cycling all over again.
OR, is there any standards which I could refer to
handle this situation.
Thanks in advance for your valuable inputs.
Best Regards,
U.Nagaraj
