If you're having trouble with a specific board, double check your Pattern, Diameter, Color and Scan Area under the 'Mark Data' tab. You can also try setting the Pitch Tolerance to '0' in the machine configuration. Good Luck, Bill

You're correct: * Sealed relays should not be cracked or have moisture intrusion. * Hand soldering relays is going to be expensive. [Using a mini-solder pot for this might reduce some of the burden.] The good part is that the problem is gross enough

There are a lot of areas that could be leading to this problem. We have some of these issues on some boards with this solder as well but the hole fill still meets IPC class 3 requirement of 75% vertical hole fill. Through hole diameter is important.

Hi Barry, Your best course of action is to perform a thermal profile and determine exactly what the times/temps are in these locations. Try to match your profile to the recommendations of your solder paste. (Time between 130-160, Time over 183 and m

Hello Since we have a few years experience with these printers we might be able to help. Is these problems always with the same components? Is this a new type of paste for you? Is there tape on the bottom of the stencil? And how much pressure do
