Hi Guys, I am going to be graced with the good luck of processing microBGA's in the near future. A bit of a step forward from printing 20-mil pitch and wave soldering 0805's, wouldn't you say? So, any of you folks who have already experienced this

"DIP, VCD" -> "smt secondary" type of process flow. In that case, dispensing becomes a must. Dispensing needs less setup than printing, but takes longer. So, for a prototype manufacturer, dispensing becomes the best choice. Sometimes a machine dispe
