Is it OK to put 0603 resistor on the 0402 pads?
« on: May 16, 2016, 09:57:45 am »
I made a mistake for the package of the resistor. The pads on the board is 0402, I bought 0603 and I have assembled 1 piece now. See the attached picture. It looks fine, but I'm a little wonder if it would have some bad effects?

It will work fine for one-off stuff

About the only problem I can think of is that it will work fine - but if you build one with the smaller resistor you find that one of the parts is out of specification - most likely dissipating too much heat. What you have here will be OK, but when you make one with the small component remember to check none of them are getting too hot.
