I'm sure there are some standard techniques to minimize this ?
Product has a number of connectors on a PCB, mounted in a box. Because the external cabling and connectors will be subjected to stress, there are (for example) hex nuts fastened through the sturdy box through DB connectors on the PCB. Then when the external cable is yanked, it doesn't break the PCB.
So, the PCB is fastened to the box not just by normal mounting screws, but at the connectors.
If all the connectors are perfectly sized and aligned, and the box is perfect, everything fits exactly... If anything isn't perfect, the screws through the box are pushing/puling on the DB connectors and the PCB.
How do folks deal with this, such that there's a nice sturdy mount for the external connector, but no stress on the PCB, given normal manufacturing tolerances ?
Thanks in advance, Best Regards, Dave
PS: This problem is much worse if the box is manufactured with a tile saw, which seems to have happened in a recent thread ;-)
