Hello!!! Just to say, I've never even heard about placing parts on double-sided tape for inspection... We always build one board placing parts on paste/glue and inspect it befor reflow. With suppliers specs of 6hours at least, I don't see any prob

Hello Mark, I'll assume that you are currently wave soldering and would like to eliminate that operation by using pre-forms or press-fit connectors. Solder preforms or solder flux bearing connector leads usually do not require any hole size changes,

Hello Peterson, If the contact tails protruded enough on the underside of the PCB, then you could do a "reverse" press fit. I do not believe that to be the case with the VHDM. Placement equipment is out of my bailiwick but; Usually small SMT connec

Hello, We are looking at new/used buildings and are faced with decisions regarding what type of flooring to have installed. I know a little about epoxy, vinyl tiles, rubber, paint and plain old ESD wax on concrete but don't want to re-invent the wh
