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

| I am interested in seeing how some of you quote smt work. Currently we quote off a bom without component packages known then look in data books to find out what type of component they are. This job will be mine soon but i really believe there is a

Hi SMTnet, I'm newbie here and searching for information on a pcb reconvertion. So in order to reduce costs on a small pcb+ componentes+assembly I need your experience on assembling only SMT components vs SMT+TH; the point is actually my PCB has abou

Obviously the cost difference between only smt and smt+th is huge though TH only 1 components,they need different material,machines,tools and control methods,so if possible just use only smt process to assemble all components,but to verify if the usb

I'm looking for a SMT prototype & small series assembly machine, needs to be very accurate, no need for high speed. For assembly batch size 1 to 50 pcb's. The machine needs to be accurate and flexible, able to place chips 0402 up to BGA components.

We have 8 layer HASL PCB. We saw molten solder blobs / balls on op side of assembled PCB. (to check, if this was a bare board problem), We passed bare board as received thru, SMT reflow oven and saw solder balls on top side of board. What could be th

Dear Friends, I need your help to understand requirements and measurement methods for bow and twist of assembled PCB (PCBA have and SMT and TH components). I already check all posts on the site but didn't found any related to my question answers.
