Can you tell me what kind of rework machine
you currently use ,SRT. DRS. ERSA or peace machine and others?
BTW, If your machine' function limitation
, you actually can use special fixutre for it, but note that the strain
gage test from both fixture and thermal shock is one way to convince yr
custormer.
It is true and customer worry about reliability problem and we wasn't allowed
to rework by special fixture.
Thank you for your attention.
Thanks and Best regards,
QiXiong Liu / 刘启雄

Although the fixture is normally way for such issue. stress issue from
unbalanced thermal shock to components should be deeply considered.
Evaluation have to be conducted to reduce the thermal shock. ......
