FYI If you are talking about resistors or capacitors or any inexpensive part for that matter, throw them away and buy more. You will have to bake them forever and they are only worth a couple of bucks. You've already spent more money than they are wo

Hi, Is the footprint per the component manufacturers recommendations? The reason I ask is because it kinda looks like the pads are extending beneath the component. Could cause the part to float up on top of the solder and not allow the leads to wet

Your MPI (Inspection Procedure) is certainly flawed. Your MPI should have caught this on the first board your produced, before it was reflowed. For help convincing yourself the part is rotated 180*, your choices are: * Get the pin-out of the compone

That is very interesting... I am curious though, why wasn't a plain blind rivet used? You probably can, but personally, I would be not want a solder joint holding the frame and the pcb... Mechanical stress on solder joints often leads to not good re
