Headphone jack was very popular in last decades, but this trend seems fade recently. What is going on?
I did have one board come back with a manufacturer error – an extra bit of copper just a hair’s width across hidden underneath a component. It looked almost like someone’s eyelash had fallen onto the board just before photo etch. How should I deal with it?
I designed a PCB with an imaging sensor that is mechanically coupled to a lens assembly using four 2-56 screws. I’m noticing that even though the screws are holding the board tightly against the mechanical structure if I flick or lightly knock the the assembly the image “moves”. I’m hoping to get a few suggestions for ways to fix the PCB to the mechanical structure. Any suggestions for adhesives or the like? Something else?
