In assembly the bare board is populated with electronic components, called a "printed circuit board assembly" (PCBA). In through-hole technology, the component leads are inserted in holes surrounded by conductive pads; In surface-mount technology (SMT), the component is placed on the PCB so that the pins line up with the conductive pads or lands on the surfaces of the PCB.

We hare having an issue with our chip shooters misplacing or not placing parts all together. We have traced it back to our adhesive machine. We are using both single and double dot nozzles. I feel that the biggest problem is excessive amounts of glue on the dual dot nozzle. The glue dots are bleeding around the part and clogs the nozzle tip on the chip shooter.
What are the recommendations on using single dots for all discrete components?
What is the recommended allotment of glue dispersion per part size?
What are some of the best ways to measure dot sizes to ensure proper placement amount on all shifts?
Thanks for your help
