We have a new assembly with bottom side components, and all the chip caps and resistors are 0603s. The dog boned shape of the caps necessitates a pretty big (and tall) dot to hold them still during placement, and when they get placed the dot squishe

| Hi folks, | | I am looking for inputs on a long-standing problem encountered in our shop: Bottom-side parts (passives) falling off in the Wave...where the only remnants of the part is a flattened glue dot of proper diameter and volume, and somet

is there any gap between the pad and terminal if we place the glue? Btw, my practice to print solder pate then punch glue then PNP component and finally reflow. Also we find drop/missing chip after wave eventhough we glue the component.
