You are playing with fire; you evaluate and specify paste for your products/SMT line, when you start adding tacky flux or whatever to your paste you don't really know what you are then dealing with - it osn't what you evaluated. We use solder paste f

Who said there was NO evaluation? The paste we chose was evaluated based on a 20 point test score as well as material compatibility. Once we introduced it to manufacturing each line had problems. For one manufacturing treated it as a drop in repla

When or before evaluating your paste you might want to find out how Readily available it is? From where it is coming to you? (Freight charges).. And how reliable the distributor is that is selling it to you. Nothing worse than running out of paste an

Hi, We are in the process of evaluate our solder paste,incoming inspection over the solder paste, stencil requirments: 1- Is anybody using/requiring 1000 Kcps or more on viscosity to your solder paste provider ? Why ?? 2- Is anybody using step stenc

First we have to look in to the current situiation of the SMT line.Is the pick and place machine very old and can not perform consistently. Is the board to be inspected is very dense and have lots of connectors and fine pitch comp.with lots of 0402 c

On our last thing like that [5X5, 32, er 28?], we printed bumps on the QFN, but you can't do that, so there's no sense in tormenting you. Ideas that come to mind are: * Search around SMTnet for a paper by Chrys Shea on controlling dispense shots as

Mentor(Valor) has dfm softwares that not only looks at the stecnicl layers buy can look at other impacts that could effect the optimisation of the stencil design, ie solder mask layer tolerances defined from fabricator-design etc - this is a upper en
