Dear Sanjay, An important issue involved when stencil printing adhesives vs. solder paste is: How do you clean the stencils after printing? Do you need two machines? Two chemistries? Two waste streams? What are the potential environmental impacts an

This is my attempt at beating the "Fuzzburg 7" translator used on the SMTnet Forum that mashes everything it sees. Below the next paragraph are three paragraphs,each with a common numering sequence, where each paragraph represents the columns of a t

This is what I might do, I would purchase either a solder volume (preferred) or at the least a paste height measurement piece of equipmment, The most important parameters with pronting are volume and registration. You need one of these inspection

Honda, Prnting Glueisn't as difficult as it sounds, as long as you have the right stuff and a good set up. It also depend's on what your going to be placing. If your just doing 0603, 0805 and 1208 than you really only need an 8 thou or 10 thou stenc

Individual process steps are approximately the same length of time for reworking a BGA. You seem to be comparing the use of the automated SMT line versus an off line rework station. Consider that the off line station is a complete paste print, pick

I am printing a ceramic paste through a 160 mesh screen that should have a theoretical wet print thickness of 53um but the only way I can get the print that thin is to increase down stop and slow the stroke. This is causing problems with the mesh, s

The material is 0.12mm stainless steel, electropolished it's thick for fine pitch but we have lot of other big components on the board which do not solder good if we use 0.1mm thickness stencil. The 0.3 mm apretures are big enough and have good rele

0.5 if you use electroformed stencil or > 0.8 if you use laser cut. 2. Always use fresh paste 3. Uses the right printer parameters for your paste(for example Alpha likes fast release of the stencil from the board - in DEK this is called separation s
