Hi Steve, Have you took the star completely off the Gantry. There are the 12 hoses to the star if Segment 1 connection hose is messed up everything will be off because everything gets measure off of Seg.1. Also, you could start eleiminating the probl

Everything rob said makes perfect sense. That said, do you have a robust, infallible paste management system? ;) Have you tried multiple tubes and multiple date codes of paste and had the same results? Is it stored properly (on the tip, assuming i

It doesn't matter if the traces have solder or not. We're talking thermal cycles. RE IAg thickness: I believe the IAg is a self limiting process, similar to IAu. Your fab may be able to help a little, but I don't expect a substantial change. And if

Heller Oven comes with a profile pre-loaded so you can start there. RTS = Ramp to Spike. Basically a straight line from preheat to spike. Also known as “Tent” profile RSS = Ramp Soak Spike. This one creates a flat line around 150-180 degrees on th

IPC tried to develop a standard to compare machine throughputs. The machine placement times are usually based on very few components with optimum feeder placement and a very large array of placements. Real life boards are rarely like that. Once I wor

Its not the max temperature that is the issue, its how much energy the oven is capable of transferring to the PCB inside the 4-6 minute window of a typical profile. In a conveyor oven this is achieved by having zones of different temperatures, but th

Hello, sir. We are a SMT equipment manufacturer from China. We have a hot-press soldering machine that can change your current situation of manual soldering on PCB board. In addition, we have a better reflow oven, the upper and lower two cold tempe

Hello lads. I run a Sequencer 2596 and have had good luck. Just recently it sounds like air is not making it into the machine. With the machine palmed down it has the required 55-60psi going in, when I release the Estop the psi drops to about 30 and

Jim, It's been a long time since I worked on one of these so this is going to be a general idea as to the issue. There's a solenoid valve that is controlled by the E-stop ckt. When in E-stop in stops air from entering and vents the pressure lines

These residues are extremely water miscible BUT you will probably need the extraction of heated IPA/Water to get the porous resist to release the residue quicker than it would do releasing it naturally in the field. Why dont you try to soak the circu
