1. How did your customers preious supplier deal with this problem? 2. Why did they not alert you these sepcial needs during the quoting process? If they have special needs then relegate the parts to hand-stuff. Don't forget to adjust your price

Cheers Greg, It's unusual to have such direct access to manufacturers & their opinions. I'll tell you what really does get us, and splicing doesn't work well on these occaisions - big SMD connectors, requiring deep pocket feeders. You only get m

Thanks for the reply Rob, This we already do. The machine will pick from the most efficient available feeder (assuming multiples of the same part number)...so when you remove the primary it will seemlessly move to the next available. When you re-in

Hi All, I think you're adressing this issue from the wrong angle: What I'm reading is an equipment vendor who has an idea about what the best way of working is (replace entire feeders), and a (potential) customer who thinks otherwise (splicing). The

I have a situation with hot boards with fine pitch BGAs that I need to build. However, there is a big problem--the auto screen printer is down. I decided that we would use the stencil and manually line up the pads and do a manual print. I can't ac

HLY: If you must build product while you wait to get the printer fixed, and if the BGA balls are eutectic solder, your approach is a good one. All solder paste does in this assembly application is supply the flux. Additional solder volume is not ne
