When you say "solder paste layer," what are you talking about: * Post-print / pre-placement quality inspection * Post-reflow solder inspection * er what?

We have two E5's, and like them a lot. If money were easier to come by we'd buy one more. Tech. support is excellent, print quality is good (I only have semi-auto clamshell machine prints to compare them to, and it's no comparison). They don't offe

Leaded HASL on small pads can be quite difficult to print on...the HASL tends to be domed rather than flat..and that can affect print quality...you really need a perfectly flat pcb pad to print paste on when you are assembling 0.5mm QFPs. If the pcb

Will they give you the opportunity to develop a DOE to look at quality vs. print life? It probably depends on the kind of placement equipment you have, but with our chipshooters we always had missing/misplaced parts if we populated dried out boards.

Dear Masdi, Solder beading (as opposed to solder balls) is usually caused by volume of solder paste, displacement of solder paste when component is placed and sometimes the proximity of the solder depositions for that component. Basically, a small a

We have been using the Pro Flo for about a year and the print quality alone is worth making the move. It is flexible in that switching over to blades is pretty simple (if you need to), and the operators love it because clean up is a breeze. The only
