Hi,
We have been having a problem with assembled PCB's having improperly
torqued hardware and making it out of the factory and think the
problem is that the hardware loosens after wave solder. We have
done some simple experiments and confirmed that this happens. The
hardware is in common applications such as stiffener bar attachment,
voltage regulator attachment and connector attachment.
- Do any of you have experience with this?
- Do some types of hardware work better than others?
- Is there a good guideline for proper torque specs for certain
types of hardware on PCB's?
Any information you could share would be appreciated.
Thanks
