Hi All,
I'm working on a board layout in ExpressPCB and I am wondering if it is considered OK to place a small via on the pad of a SMD part. To be specific, I have a bunch of 0805 bypass caps that I am placing on the underside of the board for various ICs, and I want to add a via through the pad of the cap to the top layer to connect to the power pins. I am using the smallest via size the program supports (0.36mm hole) which the manufacturer says is usually filled due to the size tolerances.
Would placing these small vias in the middle of the pads present any problems, particularly when it comes to soldering the parts down? Has anyone ever tried this?
Thanks,
Jason O
