In the northern hemisphere you count counter clockwise and southern hemisphere you would count clockwise. Now if your sitting on the equator than it can be either way.

Hello! SMT professionals, I do not know if anyone posted this question before. Last week, I reflowed our newly designed thin Rigid-Flex pcb with 0.040" thickness. I found all of pins of a TQFP48 ic did not get wetted. I could see on the heel side o

Trying to place PTH components with an SMT machine is possible but maybe not plausible. Would you have to buy specialized tools and equipment for the job ( gripper nozzles ). Are the machines you have capable. i.e.. Would you need camera modification
