I worked for a company that did fast change overs with Panasonic machines. We also had dedicated feeders that never came off the machine. But even with over 100 different dedicated parts most set-ups still had 30 or more parts to load. All feeders w

Peter, We have 2 Fuji lines. We run from 5 to 5000 piece lots. When we are running near capacity and have a lot of change-overs scheduled we have special operators that will load parts onto feeders and organize the feeders like they will be on the

On mixing paste: There could be a lot of hand wringing about the need to minimize solvent evaporation, flux separation, and chemical activity. [True alarmists will throw in oxidation of the alloy.] But I think the real concern is a change in viscosit

We run a high mix/low-medium volume smt line with MPM SPM stencil printer, MyData pick-n-place machine and a Heller reflow oven. That combination is working well for us.

Joe: I know this is not the correct forum to post chip "reworking" questions. Reply: Rework questions are as appropriate as the next topic here on SMTnet J: BGA will not reflow at any normal temperature level. I believe these chips may have been gen

I think the main cause of this condition is #3 because both #1 and #2 never change from board to board, these are identical boards with identical BGA revisions. These BGA's (as stated before) are about 3 years old.. I don't believe they are lead free

We run 2 lines: Line 1 has a Dek 265, GL5, CP43, QP242E, and Heller 1900W; Line 2 has an Ekra X4, GL541, CP643E, QP242E, and BTU VIP98N oven. Soon both lines will have new Ekra X5 screen printers and the BTU replaced with another Heller. Works for us

Rob, I think the change over on the Quad QSP2 is about as easy and fast as it can get without swapping out the feeder bases. In a high mix environment I think it is worth looking at. Regards,

Is cost an issue? I evaluated Siemens Siplace about a year ago and the price per placement was twice what Phillips Machinery has to offer. We too are a high mix/low PCb count shop. Also, Siemens has many hidden costs and the references I talked to
