TOOLING > OFFSET. The pcb stopper is attached to the camera and a default stop position is calculated from the PCB dimensions. If your stencil image is offset left or right then you can either fiddle the pcb size or input the offset. Offsets front an

You can get a better Kapton tape (you must be using the cheap stuff) that leaves no residue. If that fails then you can get edge maskers that slide overtop of the finger and they are reusable. Or you could get a solder pallet made for the assemblies

If I have four PCB's in a Panel with four different angle of rotations (0, 90, 180 and 270 degrees). What would be the formula for my Offsets? I am trying to compare our techos method of programming the Chip Mounter as I noticed that he can't have th

Greg, at least on three different brand machines, I was working on, the offsets rotated with the board. If you start out at 0 deg. and the offset in the top left corner than it is on top right at 90 deg., bottem right at 180 deg. and bottem left at 2

Without using a glass plate you could check if your jaws could properly align the compomnents by writing a small vice versa program. Place a component in a 0 degree angle and another one right next to it in a 180 degree angle. Built up a line of lets

I am looking for a Masking tape for Gold fingers on a PCB . It should not leave any residue on reflow soldering ( 220 deg c). Currently, I am using Kapton tape with Silicon adhesive. It is leaving minute quantities of residue? The fingers are al

Most RTV's depend on atmospheric moisture to cure. You can put them in an oven with a pan of water and that will speed up the cure. I'd suggest about 150 to 180 degree F, time period to depend on the thickness of the RTV. You'll have to do some tests
