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... 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.

Remember that heat is needed for soldering but heat also degrades components to a certain extent. So with that I am always in favor of the least amount of passes through heat...be it wave, reflow, rework...the better.

There is no specification.

Try searching the archives on => heat and cycle*

Here's one of the threads you'll find: http://www.smtnet.com/forums/Index.cfm?CFApp=1&Message_ID=48102

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.
