Greetings, Is there a Mil Spec or IPC spec on how many times you can wave solder a PCB? I did a search on this forum with no results. Common sense says two or three times. I need documentation.Thanks for any info.

Hi PeteB Do you know PeteC? Anyway, it all depends on your most sensitive part. Look up the spec sheets to determine. Most general parts can take 3 or 4 heat cycles easily.

Hi PeteB... I dont think you will find any Specs...but that I do not know. What I do know is it depends on the make up of your PCB and Components. Obvious haveing components that may be sensitive to heat the less you want to run or pass through. Re

Our customer ask us how many repair (component removal, change and soldering) we guaranty for SMT components on our printed wiring board. We all have the number "3" in mind but we can't justify it by a standard. We can't reply "state of the art". Doe

I am trying to figure out how many feeders I will need for our first venture into SMT. I have broken down our largest board we would build into the different feeder types. What I need to know is, how many extra should I order? Why?

We do not have any electrolytic capacitors on this board.
