I wouldn't touch one of these Chinese machines if a reliable "no headaches" experience is what you are after. I'm sure they do OK for whatever it is they are designed for, but actual volume production not so much. As others have said, proper machines

We're quoting out a new board design, and one of the prospective suppliers is pitching a silver coating process over hot air leveling. We haven't had experience with boards of this type, and I am concerned about any processing issues that may come u

By Hot Air Knife I assume (leave it alone Dave F.) that you mean a debridging knife located at the exit end of a wave solder machine. Russ is right, they are not a good substitute for a good process, but once the process (w/o HAK) is developed, it

Steve: Someone is trying to trick you. He/she is trying to be very smart, but he/she didn�t anticipate this "dark haze" coating problem. I suspect that this person is someone you speak with every day in your plant. They may be the one that came-u

Casey, I will start with the lack of thermo-couple control - The unit I have is based on time and temp. exclusively. What happens when a cold board gets reworked vs. a hot board? No bottom side preheat, the heating is very localized to topside a

I have seen this problem several times on several different IP3's... When the MTU is about to pick a part from the tray, the machine will just stop. No error, just says, "producting", in green. E-stop, reset and start again, and you hear air from
