via in smt pad

Electronics Forum | Fri Mar 26 17:12:17 EST 2004 | ben

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

Yeh, the IPC courtyards are for old ladies. I want to say that at one time IPC was talking about a new set of rules. Maybe, 7351 - SMT Footprint Design Guidelines??? Anyhow, Jim Blankenhorn at SMTPlus [ sales@smtplus.com ] has done THE best job o

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

Hi, That's great, and I did not know this was possible, as I did not see that thread when I searched the archives. Do you know of any companies that take your board outline and will design a palette to hold it through the printing, smt loading and

Paste In Hole "PIH" or Pin In Paste "PIP" are two different names of the same process. As far as I know this is fairly simple: the reason from the beginning is to avoid an extra process step/steps in the production line. That is to produce through h

Low Melt Solder Chemistry for use in Rework Process

After some precursory experimentation, I am planing on employing a form of low melting temp solder for use in reworking some very dense, copper core PCB's, both SMT and THT, which were originally mounted with 63/37 solder. The main problem with the
