We'd guess that your white residue on the solder is from minerals in the supply water. We expect the levels of these minerals that you see: * Vary depending on the season. Check with your public water authority for anaylsis. [Recognize that this ma

2 waves is correct. While running the glass test panel over the chip wave (1st wave) you can see gaps due to the turbulance. What I did find was the gap of the chip wave was not closing up enough so I adjusted this which made it better. What is the p

The issue you are seeing is in fact the Battery that is in your machine. It looks like a motorcycle battery. It is usually located somewhere in or around your power supply. It should be reading an output of 18V. This battery is used in the event of a

We haven't used no-lead yet so I can't speak to the specifics of that part of the equation, but am I the only person here that sees "thick board or a board with a large ground plane" and immediately thinks this is a thermal issue? Am I oversimplifyin

I agree with Chris. Not all but SOME components definitely had to change to be able to withstand higher heat. I would watch out for some plastic connectors, possibly some active components, and definitely many electrolytic caps. Older stock compone

If you can, put a pressure tank near the machine. It will help stabalize the air pressure, but only if the compressor is providing enough air in the first place. Throughhole PNP machines tend to take air in big gulps making the pressure go up and dow

Any experience with the encoders and ball screws that drive the stage? We are seeing a pretty large y-drift from the 'top' to the 'bottom' of the board during x-travel. I've tried to measure this using the teach function and the x-drift from the sm

Slot 11 in the I/O box is the one for B.E.C. pcb, the offset is 2125 in the x and 500 in the y axis. The template for the B.E.C. is triangle in shape and is the length from corner to corner on the rotary table. You can also type in sh sys and look to

Might want to check to see if the weight of your part has increased. If it has increased, you may not have enough surface tension to hold the part on the board. I am assuming you already checked that the component isn't getting hit by something in
