| Is it bad to reflow solder paste on empty pads? |

Hello all, I have a PCB I'm making for a school project. When I designed the PCB I added some optional footprints for some 1206 filter capacitors and resistors in case I decided I needed them later. Unfortunately the stencil I created has those parts in it, so if I use the stencil (without taping them off or something) those pads will get the solder paste on them. Is if safe to bake empty pads with solder paste? Will it make it impossible to install the parts if I decide I do need them? I've only every reflowed a couple breakout boards, so this is my first real reflow project. Thanks! |

No problem. You might have to wick off the solder later if you want to install the parts though. |

It's very common to see production PCBs with unpopulated component positions, probably for much the same reasons you have them. Why are you thinking it would be bad? |

Sensible. :-+ I have always said the "dumb" questions are the ones you do not ask - and you pay the price at some point. |
