Hi, I've just splashed out �60 on IPC-A-600F trying to find out the formula for measuring the bow and twist of raw PCB's. Much to my dismay there are 10 lines on the subject in the whole standard. Worse still is that it tells me nothing I don't alre

Rob, Fantastic! I sure wish we would have put our requirements into our last P.O. The G.M of the manufacturer of this machine flat out promised and guranteed a certain CPH after reviewing the products that we would be producing. When the machine w

Any help/suggestion is much appreciated I am doing lots of BGA Reworks from a small uBGA with a few balls to a large BGA with over 1500 balls. The reworks have been done on SRT 1100 Series Machine for many years. SRT 1100 Machine is good for the c

CSP and BGA soldering difference.

"Guest" is right, actually. CSP's are essentially BGA's, but typically the pitch and ball diameters are much smaller and in some cases, the pads of the CSP's can not be screen printed. If that's the case, you'd have to have flux-dip capabilities on

CIM systems and Final Assembly

Electronics Forum | Tue Jan 23 11:42:05 EST 2001 | aiscorp

In the past when the electronics industry was only beginning to mature, many companies considered CIM systems or even just basic CAD/CAM functionality a luxury of only the large OEM's which would develop their own tools. Now, with the competitivenes

CIM systems and Final Assembly

Electronics Forum | Mon Jan 22 15:01:32 EST 2001 | aiscorp

CIM systems for electronics assembly have traditionally considered the PCB only. Final assembly "modules" are often attached to traditional systems to accommodate this common requirement for pre-PCB assembly, mechanical assembly, and final assembly

repeatabilty and measurement for quality

Are you doing actual measurements of the dummy parts placements? or are you just doing a visual go/no go check? If doing actual measurements, be sure to use mil inch units of measure rather than mm. Mil will give you more accurate readings. mm force
