The key to longevity in any automated soldering machine is in the preventative maintenance. If the machine has had regular maintenance preformed on it, your job will be that much easier. The 1st thing I would do is to either throw out the solder t

We have been experiencing intermittent problems with the solder masking bubbling up from the bottom side of the board, after wave soldering. Our board fabricator claims that none of his other customers are experiencing this problem, and that it is pr

Advantages of using a stencil cleaner verses manually cleaning stencils: 1. Using a stencil cleaner ensures no direct contact between operator and solder paste (lead being the primary concern). 2. Most stencil cleaners remove 100% of the solder p

These are all good questions. Dip fluxing is fine. Make sure you let all the remaining flux drip off the board. Letting it drip into the pot will cause a lot of spattering of hot solder � be careful. Dipping the board slowly into the pot should

Hello Carl, Thank you for the feedback. You are absolutely right. I was remiss in not addressing the other questions. 2. 440-R SMT Detergent will clean RMA and No-clean solder pastes in 1 � 2 minutes using ultrasonics at ambient temperature and 5

There are lots of examples of changing a parameter in one direction to fix one issue causes a different problem. Once I asked a layout engineer to adjust thermal relief for through hole parts. First he said ok but a day later he said that he couldn't

Get-out the razor blades, bud. You could run that sukka for 6 sec dwell, cook breakfast on it, and you still will not get fill. [Hole file that is, breakfast will go along ways if peckish, though.] You could fire-up the depleted ozone rework gun [

120 degrees F (49 degrees C.), check the fine-pitch apertures for shape distortion (stainless steel has a very poor memory, once it expands, it doesn�t always contract back to the same position). Check for dings and dents. A good stencil cleaning pr
