Via in SMD pad

#1 Post by KevinA » 04 Oct 2017, 08:05

I've been working with 3.5mm phone jacks and barrel power connectors, a couple of suppliers suggested adding via to the SMD pad to help support the Jack. So I tried it:

I built this with PCB editor, made one PAD and added 4 via's, cut and pasted then renamed all pads but I had to rename each via to pin 9 (Why did vias pick up the need for a pad number?). Built a component with 9 pins and added the pattern after saving it into a pattern library (NOTE: Bug, the PCB Editor created the pattern but when saved as a component to a library I don't have a means to name the pattern, I have to open the pattern editor and select the blank space then name it.) I created a PCB and placed the pattern:

I appears this will work and I believe if I rename the via to 9 (last pin number + 1) before copying it this won't be so labor intensive.

My Suggestion would be a tool that allows placing nail down vias on SMD pads as arrays without associating pin numbers with the vias.

The request is reasonable but you can already have more pad numbers in the footprint than in the component. I often add extra pads e.g. to a USB connector, the component shows the normal pins 1-5 which includes a ground pin for the USB connector, then in the attached pattern dialog box in Component Editor, you can wire the extra pads to the one ground pad just by click/dragging from one pad to another in the pattern window (it shows up in red).
