We make a custom mini stencil to print the paste onto the QFN and flip over to load on the rework station. The mini-stencil was designed for SRT to pick up the QFN. Check BeamOn (stencil house) for detail. Good luck

Have you checked the component height in the package data to ensure that it is the same? how about the PCB itself, could there be some warp or twist thay may cause the component to be dropped onto the board? any support problems? this is all I can

Well, at least they're not drawn on parchment paper or chiseled into stone. Have you tried contacting the D.O.D. about getting these transferred onto something else?

it's a collect and place as the head is fitted onto a moving gantry, therefore it collects all the parts and moves to the placement position and places them. thats my understanding of it anyway.

Does a machine exist that stamps epoxy onto angled surfaces and not just vertically? I would guess this would be done by either tilting the specimin to be stamped with epoxy or by turning the stamping tool at an angle. If anyone can recommend somet

some water managed to leak onto a couple of backplanes boards. The OP. has blown any water off the boards, would these need to be baked ?

Elektrobit (JOT) makes a wave unloader you can use to put your board back onto an edge conveyor (if you are using just a belt on your oven now) and then place a FIFO or Mag Loader after that.

It is not common practice to perform this function.What is advisible is to cover the PCB surface with white copy paper.Screening onto the copy paper will give you a clear indication of your solder screening profile.This way your PCB's will stay clean

Grant, I think this Guru has never set foot onto a production floor. He just looks at data from the machine manufacturer. As you have found out the hard way this data is not the full story. Jerry
