John,

As others are stating there is no one "normal". Nortel (still waiting to see
if I get any of my pension), did 0 to 100C, 3000 cycles for long life
product.
Regards,
Bev

Subject: [TN] Thermal Cycle Testing

Good morning !!

 

A question came up on reliability testing.

 

Typically PCBA's are thermally cycled as a part of reliability testing
usually for 1000 cycles.

 

What is the group's experience for non-military thermal cycling ranges?.

 

I am often asked to use 0 - 100c sometimes -40 to 85c and sometimes various
other thermal cycles picked from the JEDEC standard.

 

What is the groups experience for this?. I am trying to establish "normal"
practice.

 

Best regards,

 

John
