The 5DX weighs 8000 pounds. Can your product bear the overhead? We use acoustic microscopy to find BGA opens. We have not had good luck finding opens with other inspection technology. Has Agilent told you that you can detect BGA opens? How is th

So, yer loosing parts between place and reflow? That would seem to say yer: * Paste has lost tackiness [check the fine SMTnet Archives for a sample test.]. * Really not placing the parts that you think yer placing. * Knocking the parts out of place

you look like a pizza with bicycle parts, instead of anchovies. SITUATION #2: You are riding your bicycle with �souper woad gwabber� tires and a 50 ton dump truck loaded with animal waste smashes in to you and knocks you and your bike over a cliff

From the questions that I am asked from week to week, there are a number of key differentiating factors for tooling classes. They could be considered the headings of a decision matrix, where the tooling options are rows and the following items are c

There are three types of tooling, on a continuous scale a. Manual b. Semi-Automatic c. Automatic An example of a manual system is magnetic pins or a setup where pins drop into a fixed grid. Semiauto would be a system that automatically sets the t

This technology currently works with stencil printers, placement machines, and dispensing equipment with equal success. Not all are commercially available yet. The placement machines with a moving table and weight resrtrictions are more of a chal

I'm interested in process information from someone who has experience with this package, such as pad design, stencil aperture dimensions, stencil thickness, unique issues, profiling, solder paste. Design is considering this package for future produc

Two places to start your search are: 1 Look at last months "SMTnet OnBoard" Forum with Gil Zweig of Glenbrook Technologies. Gil presented his thoughts on the completary capabilities of xray and whatever he called the ERSA scope. 2 Review the fine

We have looked into it and were very impressed. I havn't seen another peice of equipment that can bring back visual inspection to a BGA solder joint. We havn't yet purchased one because of budget constraints, but I am keen to eventually get one for o

Saw one at Apex last year, pretty cool device. Not cheap, though, as you've stated. Zarrow thinks everyone that's doing BGA should have one. O.C. White makes an instrument that does something quite similar, although I think it uses more mirrors and
