We were using TL1240Y Tack switches for 2 layered PCB and posted those switches by hand. Now planning to re-spin PCA where we recommend that part to be added on SMT process. So looking for a better and opt switch with same specs. Please suggest me an

I'm looking for some SMD shims or something to solve this problem. We have a coin cell on a PCB and the side that contacts the PCB also has traces under the cell that don't connect to the cell. So I'm after some small dots of something suitable for

This does not look difficult. It appears the rectangle of proper size and spacing would work for both, or even a square pad. Don't make it more difficult than it should be. But then I could be missing something?

Rather than using an over-lay of both pads, I would just stay with a rectangle pad shape, a little wider to accommodate both footprints. Keep it simple.

I would consider to have mask in between the leads and have it open a little bit more than the copper Thank you. That is exactly what the NSMD pad is!

Yes, but I have seen designs where the whole row of leads has no mask(which is also a NSMD)

If at all possible, you definately want solder mask defined pads. Without it, you will struggle with solder bridging. This is especially important if you have a larger size board.

Hello gurus, I am a hardware designer with a small company. We are about to send a new PCB for fabrication. This board uses dozens of tiny QFN, DFN, and similar packages. As a final check I have been going through the datasheets of all these parts t
