Do you have a software that you can use to create dimensional array drawing for PCB using gerbers or gerber input. If not, do you have software that can open board house gerbers and create a dimensional pdf drawing? Thank you!

Transmission x-ray inspection is the technique most people are familiar with. Since materials will absorb or transmit x-rays as a function of their atomic number and thickness, the transmission x-ray image provides a two dimensional represenation of

I am currently in the process of setting up an SMD Parts Package Database. The database will contain dimensional information to be used by the placement machinery to process parts (I.E Package Type, # of Leads, Lead dimensions, Lead pitch(s), etc. I

DCS testing has detected exotherming in samples of stock FR4 laminate material. The exotherming subsequently disappears from the heat flow plots when DSC testing is repeated a second time on the same samples. Can this non/ under-cured material cause

I'm writing the procedure for buying off the stencil. Can someone help to guide me on the most effective way of doing this job. Other than tension, mylar matching, dimensional checks, what are things that I need to consider. Pls help & thank you in a

The major problems are poor layer to layer bond strength(due to surface tension of most fluoropolymers),and poor cold flow,or dimensional creep of these materials.Please also click on Chapter Author Konsowski,listed above.E-mail form will pop up when

| Is there a good way to inspect BGA | balls ? Is there an inspection piece | of equiip.? It depends on what you intend inspecting. For dimensional and tolerance measurements, I have used optical comparators. For solder ball voiding, X-Ray is used.

So does it mean Magnetized Blocks, are not going to be a concern for magnetized machine tables? or are not going to generate electro-magnetic fields? can anyone please help unravel this pop-quiz question? (keeping in mind the support block has rathe

What are some of the Chip-Shooter machines that have this Golden Board comparison? I am aware of a dimensional image overlay but no measurement is performed by the machine to determine accuracy on these systems that I am aware of. -JAX
