the only problem i see here is the neighboring components (depending upon the component density) will surely undergo a second reflow during the rework stage for the BGA. this way the only lead you will have in the BGA assembly is if you are using HA

Hi, I see that the wave angle of the wave solder machine takes a major part on soldering SMDs if they are assemlbed with glue. To avoid the shadowing effect and bridging what would be the best angel of the wave for Sn/Pb & Pb-free soldering processs

Hi, I am testing some lead-free assemblies using ATC. it was suggested to me that if i do in-situ testing, then i should measure the starting resistance, and subsequent resistances values after n cycles, and when the resistance value increases by 1 o

Hi Ajay, Does your company currently use any quality standards or is it made up as one goes by the QA department? You might find that using IPC 610A Acceptability of Electronic Assemblies very usefull. This manual is our base line for acceptable or

Has anyone adopted Dual Lane Tape feeders in their production of SMT circuit board assemblies? Universal Instruments caries one if people are not familiar. I am looking into a smooth adoption of this into production and have been looking to gather a

We are using selective soldering pallet, which the soldering flux is Interflux 2005M. We encountered the poor hole fill mainly at the heat sink components. Initially we tried to apply more heat but tend to overkill the flux activity. After some modif

JAX: Thanks for the reply. We did send one of the boards back to the bare board supplier and they do concede that it is black pad. When you inspect the assembled board under a microscope, you can easily move the entire solder joint away from the p

Need more info.. SMT only inspection? SMT/TH inspection? Solderability inspecting? OCR/OVT inspecting? (reading letters and number) Lots of alternate parts? Established database driven programming software? (Circuit CAM, Flexa, Assembly Expert, CIMB
