The UFP was a designation for "ultra-fine-pitch"; but, for the most part, you should be able to get the same placements out of both machines. Anything 0402 or above can be mechanically centered. The UFP machine will lean on optical centering for .5

Let's think about this, there former filed service engineers. I bet they got out of field becasue of being laid-off. Typically the NON-Performers are the first to go. Hint hint.....former field engineers! Quad 4C's when they were new to the marke

This is one of the biggest mistakes with the Lead Free process. We have all listened to the 'industry experts' and followed their advice and unfortunately got it wrong. Keep the dwell times (dependant on alloy selection) the same as Leaded so you are

Since I'm new to the forum I probably ask previously answered questions (that I have not found) but I would be grateful if someone could clarify this for me. I'm in R&D at a company where we design low volume (1k-10k) fairly complex PCBAs for our pr

Hi Clarissa, seems to be a real start up situation you are in. For the printing there is IMO no need to buy any sophisticated automatic-vision-alignment-self-cleaning-inline-and-more-machine. Features you need: - adjustable in X-,Y-,Z-axis (individu

I've used an on-axis camera lighting for other components with a good deal of success. (But not for CGA's in particular) I would think it should work pretty well for a CGA application. I've done some pretty odd looking parts with this type of lightin

This is a question about complying with J-STD-001 solderability testing. Do any of you have your vendors certify that the components and PCB's that you buy from them comply with the solderabilty requirements spelled out in the -002 and -003, in lieu

Ken...you are right on the money. I couldn't imagine someone new to SMT assembly getting themselves involved with such an old platform. Besides I would have my doubts that a Quad 4C can even handle what this guy would want it to do. 0402's on a 20 ye
