John, We tape (usually high temp tape) flex to a fixture (usually 0.090" piece of bare FR4). We make an outline on the fixture to get a rough location then use fiducials on the flex for alignment. Print, place, reflow, cool, remove flex. When the

So i have a pcb that is not panelized and it is a single pcb. The problem is that the pcb is small, so it needs to be on a fixture for it to go through the topaz-x machine. The xy data that the customer provided is for the pcb only. How do i include

If you are trying to reduce the weight of existing fixtures that may be more difficult and expensive than starting from scratch. If you want to reduce the weight of future fixtures and we could discuss some concepts that could save significant weigh

I think Patrick is on the right track. Try running the fixture 180deg out from typical, if possible, and see if the problem goes away or moves to another fuse clip. I've also noticed some wave fixtures can create air pockets that won't allow proper

A good fixture is the key here. The first side should be easier than te second(if double sided). In both cases I will try to level the top of the board with the top of the fixture. Try to lock with pins comming from the fixture to the PCB holes. This

A few of the more common defects If bridging or insuffienct deposits occur on the printer, one of the first things to check is the tooling. Misplaced hard tooling pins or poorly designed fixtures have a nasty habit of breaking components on side

If the whole board is shifted then it must be a problem with the clamping of the fixtrue to the machine or the board to the fixture, or the fiducial reading that is incorrect. Are the fixation of the board to the fixture the same in both programs? A
