| Hi Everyone, | We plan to build, for reliability/experimental/research purpose some CSPs (namely Tessera microBGA 46-I/O 0/75mm pitch and TI 64 I/O 0/8 mm pitch). the various factors that we plan to evaluate are the reliability and assembly concern

Are you sure about your dimensions? .45mil ball diameter and .8mil pitch, and a body size of 16x8mils is really, really tiny. I assume you mean millimeters and not mils? 1mil = 0.0254millimeters If your stencil is 5mils and your ball diameter is

That pad had a 16 mil dia, so I arrived at 20 mil squares by adding 2 mils to each side of the pad. Following that logic, a 12 mil pad would use a 16 mil square. But a 12 mil pad is on a finer pitch that isn't mentioned, so you should definitely
