Hi. We are planning a production run of a board that utilises the SEMTECH SLP2710P8 8-pin device (2.7 x 1.0 x 0.58mm). The part orientation on the board necessitates that the squeegee print direction approaches the stencil apertures on the long side

We are using a vapor phase oven which we have used successfully for a number of years with both leaded and unleaded solders. Recently we experienced problems with a no lead BGA that has low silver balls. The problem is that the soldered boards do no

Hi All, Let me summarize the key facts and findings: 1) This is not a permanent problem. Only one production batch was affected. The cleaning solution was exchanged and now the cleaning process runs normally. 2) Probably the residues are not ion

Hi, Everyone! What do you use for Assembly Drawings? I need Electronics Assembly Drafting software, and I am hoping to hear your recommendations. The core functionality I need is the ability to translate X/Y coordinates (ASCII file) to my Gerbers

Thanks for the reply, Sr.Tech. Sure, I'm considering all of the things you've mentioned. It certainly seems that service and spare parts are easy to obtain for the Quads, which is the main reason I am even considering the dinosaurs (that and they ca
