Hi, I am having some problems with my Fuji CP6 placement repeatability. The placement drifts during the build about .06-.10 mm on parts. It has happened on several different builds this week. It is enough to cause some defects after reflow on smal

John, The first thing to check is how tight the boards are being held in the conveyor (assuming you are using a finger conveyor). They should be a little loose at the input end so there is some room to expand. If the boards are held too tightly, when

| I need to cure conformal coat on a 19" x 15" board. The material needs 7 - 10 minutes at 100deg C, but I have limited floorspace so I'm looking for an oven with about 36 inches heated length and 18 or more inch wide belt. The material we are consid

Mike First, you MUST make sure the oven used is extracted. The coating will contain TDI. This is not nice. You would be better considering a silicone solventless. Try contacting HumiSeal. They had a material on the TAC line at Nepcon West that lo

SPM is superior. SPM has larger print area, up to 20� x 19", vs. 17.7� x 15.7� for the UltraPrint 100. UP100 is microprocessor controlled while the SPM has a PC. The SPM cameras can be positioned more rapidly and with greater accuracy than UP100's.
