180deg celcius the module will be released. Or heat the whole system above 180deg celcius, and release the module by picking the PCB (not the shields) There is a socket designed for the module as well did you know? b.r. Arjan

If motor direction cannot be reversed, just place the conveyors turned 180deg. and the problem is solved. - Cheers !

Normally when you just rotate one of the boards (circuit) by 180 deg, you'll find all the placements shifted by complete board length in X direction. This is because the board is rotated 180 deg with the board origin as the pivot. So you'll need to a

I hear you on the profiling issue. That won't get at the issue any how. Your observation of solder wetting confirms that solderability is NOT the issue. You may be seeing a "cold solder connection". The issue is the TCE of the different materia

Larry, 180 Deg. C (?) to start the profile seems a tad on the high side for a 7-zone oven. You risk too high of a ramp rate and solder beading. At 7 zones, there's no reason to get too hot that fast.

Don't comprehend the baseball cap comparison, could you try a different description maybe? You say leading edge, have you turned the board 180 deg. and does the defect follow the leading edge of board or the same balls on part? Russ

Thanks for reply. I've tried to arrange the sequence already, but the panel is 2x10 and 1 row is 180 deg rotated. I have an idea to duplicate component and place it at the rear mount plate.

We commonly put two images on a stencil 180 deg apart to save space and reduce cost. We keep the image centered left/right because the machines don't like it when they are offset, but turning them around front to back is no issue.

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

Russ, unfortunately at the moment the preferred option of hi melt isn't available due to copyright issues. The current ball is made of 46/46/8 tin / lead / bismuth. ther ball's are 0.8mm in dia. The alloy actually has a plastic region around 170 and
