Tough call without seeing the board, but here's my best guess. You don't say if the glue dot is greater in height or diameter in the locations where you have printing (silkscreen), but I would guess that you might get either, or both, depending on ne

i just thought that it because of difference thickness between the silkscreen and without silkscreen. if we apply the same pressure and dispense time to this two difference location, the glue size will be difference. location with silkscreen will rea

Most of pcb have white/black printing at bottom side of them to indicate the chip location. Normally, this printing are the same location to the place that glue will be mount. My problem are the glue size between the point that have printing and not

We 'bend and clip' with good old fashioned needle nose pliers and side cutters. A typical size for a run would be 20-30 boards. Many of our designs are over a decade old and are fully TSO'd (FAA standard) and we can't change anything in the design.
