I use Pentagon EMS (503) 924-2747 with Chad Haima. Note: I do not get a penny for referals. I just like the service, super fast, high quality and excellent customer service. I have worked with them for about 4 years. Thanks, George

That is a tough one because of package size I agree, as noted previously it would be good to know what the current PCB pad layout is. first thought does go right to an adapter board of course! is this a volume build or just 20-50 pcs? dead bug and ha

Hello mickd, 1) The EL data & Vision_type is NOT necessary when using MCS30 for IP1 machine. note : your input of the above might have cause confusion during VP, hence the OS error. 2) I would suggest the following... 2a) lower the Lead_check_are

My personal favorite is the Siemens F series and the UIC GSM platform. Both Siemens and UIC have awesome resources for csp, flipchip and baredie processing - Siemens= Dan Baldwin from GaTech; UIC = George Westby from UIC labs. My second choice would

On over printing, the general issues are: * Paste deposits being so large that when reflowing, collapse onto many, rather than a single solder mass. * Paste expanding during heating and being close to other solder deposits and bridging [as you say].

JD: It's important to note that FR-4 does not contain PBB or PBDE. The bromine in FR-4 epoxy comes in the form of tetra-bromo-bisphenol A [TBBA], which polymerizes and become part of the cross-linked epoxy. Bromine, in the form of hydrogen bromide, i

We have the same problems with cut/tape parts. But, we specialize in short-run prototypes, so I don't have much of a choice but to deal with it, and find a way to make it as easy as possible. We just demo'd a splice tool from Sierra Electronics (ww
