Hi Manuel, most passives are chip components. These tend to self-center/align during the reflow process. However, you need to ensure that there is a uniform balanced solder paste deposit. I had tried few such ovals in earlier stencil designs and resu

Just about to set up a lead free solder pot exchange system for my Electrovert. Wondering if anyone has had success using say large ball bearings or materials which will sit inertly in the bottom to occupy space and reduce the alloy required without
