I agree with Joris. But to add to his comment, the type of finish also has a direct affect to your wave solder process. Going from a gloss finish to a matte finish may help a lot. As for humidity affecting your wave - I doubt it. I use a water

I have an MSL3 part (a relay) supplied in tape and reel. From what I am able to determine, these parts require baking at 257 degrees F for a minimum of 8 hours once the integrity of the seal is broken for over 168 hours. How are parts baked at th

Oh, for a second there I thought it was 257 C, not F. Solder temperature! Still, one WEEK at 257 F seems way extreme. Maybe this is to bake out a part that has been underwater for a week. Is this a military part? I can't imagine any commercial-g

We're unfamiliar with such component dryout requirements. Commonly, tape & reel cover tape will seperate at 60*C. So, even if your baking on a metal reel, your should keep the bake temperature ~40*C. Sure makes you want to use these parts during th

According to J-STD-033 Table 4-1, the bake out time to restore the clock to zero is not only determined by the MSL level, but the package thickness as well. Section 4.2.2 states "SMD packages shipped in low temperature carriers may not be baked in t

I'm currently looking for a tool to be able to convert TH components to SMT. Looking at each datasheet is to time consuming, we will be needing to convert TH to SMT for a customer. Their bards have approx. 3000 parts TH. We've got the Arrow to find

What kind of boards are they? Unless they are very simple boards, you won't be able to just replace every TH component with a SM equivalent. The inherent LCR characteristics of the board will change I think the normal way would be not to change the

Dave, I'd be skeptical too, with that response! I've got a Culligan DI system installed here, and it's got it's own resistivity test meter. When the light goes red, it's time to call and get my resin changed. It's worked out pretty well here. Ba

I have requested info on the disposable cartridge. I was told it was made for lab use and has an indicator to show depleated use. I will try to determine how the indicator works, ie. measures quality at the outlet (hopefully) or some other scheme?

OK, I've found out more on the disposable cartridge. It is made by Siemens. There are four in the series. One of the part numbers is 3C0600002. It has colored resin and changes color to indicate depletion. Has hose connects each end. I will try
