I proudly just received my 1st self-designed PCB, but alas, some holes are too small. I had 6x 3.5mm stereo jacks on the PCB (they have 5 pins each) but did not notice that the pins are larger than the typical resistor or IC - no matter how hard I push I can't get all 5 pins in (and have already broke 2 components in trying!).
Is there a cheap tool I could use to make the holes just that bit larger? I have 30 holes to work on so hopefully something that won't take an hour her hole!
