We are a medium sized PCB assy. house manufacturing about 2000 motherboards a day. There is a major problem we are facing at the wave soldering stage, i.e. warpage of the PCB. As soon as the PCB touches the wave it warps severely from the centre to

I operate at the hobby/educational end of the SMT world. My little book on SM is however listed in many training centre libraries and I thought it may be useful for your readers who are starting out in SMT: The book is: "A Practical Introduction to

Hi all, we have recently seen a design that consists off a QFP100, pitch at 25". Also in the centre of this footprint is a FBGA165 footprint, pad size .4mm @ 1mm pitch. We have been informed that we will fit the QFP. I want to remove the BGA pads fr

I have recently encountered a new pcb design with a very high density of components on either side of the pcb. One of the suggested "fixes" is to use the smt pads as vias i.e. the via will be drilled thorough the centre of the smt pad. My concern i
