All i used to do was blow them with an airline to remove the excess moisture then bake them for 15/20 min at 100' in an oven and that seems to work fine, i did get the info from a 4 stage cleaning guide for the actual cleaning solution we used but it

Check also the specs / recommendations of your PCB manufacturer. We bake boards 4h/120°C before reflow and after automated cleaning (it´s not FR4!) and also if we have to rework with the autometd rework- stations (massive IR underheating ,..). Regar

I appreciate all the feedback. The reason I was asking the question is because we have an internal documnet that states we need to bake for 16 hours after the boards are cleaned. This just seemed to long for what little moisture is really removed. I

I need help with how long do I need to bake out double sided PCB's that have been cleaned. The units will not be reworked but instead will be moved on to hand stuffing. I have looked in IPC CH-65B and J-STD-033C. I get information for parts if I am r

Hello Dave, I hope that electronic slap didn�t hurt too much. Robf, I am sorry that you did not agree with my initial response, but the answer is very detailed and most of the support material I have is only in paper format so I need to either snai

UltraSonic cleaners do a good job of cleaning both stencils and misprint PCBs. Make sure the frequency that the machine comes set to is ok to use with both stencils and misprint PCBs. If you are a CM make sure your customers are ok with using the ul

Hello, I am planning to use a water wash flux. As this is new to me, would you guys share what should I be aware of? I know cleaning PCBs itself presents issues. If you can share your experience so I can prepare better, it would be great.

There is also an article in the March 2007 issue of U.S. Tech magazine that reviews ultrasonic cleaning technology for PCBs titled "Reducing the Cost of Misprinted PCBs". The information is also relevant to post reflowed PCBs. A PDF copy of the art

Wasn't aware of that. We're using a no-clean with RF pcbs, and that's something to bear in mind for the future - thanks.
