Hi Dave, No... It was not made by Aqueous Technologies, who, by the way, is very well still in business! There must be some water that is not leaving the system. High quantities of organic growth cause the smell. Does this machine have filters t

What does the filter housing smell like (inside)? How often do you change filters? The smell is probably from organic growth. Do you have slime growing on the inside walls below the water line? Does the bleach temporarily fix the problem? What is

Could also be a ground plane under one of the terminations of the cap causing heat sink troubles during reflow. One pad liquifies/solidifies before the other. Don't know a good solution for this outside of reworking them.

We think if you follow your suppliers instructions, you should be OK. Why not have your quality people rip a couple of the soldered heat sinks from the board to assure themselves that your soldering process is adequate? Give them a pair of pliers a

won't your lead ship sink? Better get that potato out and start rubbing!

Hi, Yes, we do. Above that component we have a heat-sink to the metal chassis. We are thinking shocks to the chassis could be traveling into the board from that point. Grant

I assumed he intended to glue the nut to the part, turn the board upside down and run it through. Thing is, you might seriously have to crank up the heat to get it to reflow with that big sink on there.

We generaly reduce 25% and get great heat sink capability. Mind you that we do not perferate the pad with vias as recommended. Our toe ends are not plated, so getting any toe fillet is impossible.

We use 1B73 Acrylic and coat right over an IBM processor which gets a heat sink mounted on top. Never had an issue after 5 years of production. Dont forget to post if you find anything out though.... JD

It's common the heat sink LED. Here's why: http://www.lunaraccents.com/educational-LED-thermal-management.html
