Maybe I used the wrong terminology here. Thanks for the dimensions but that I had them already. What I need (and perhaps someone from the design council could help here) is the pads dimension required to get proper solder joint. What we have from our designer at the moment is quite small and honestly it looks like a via more than a pad. According to IPC-2221 the minimum annular ring requirement is only 0.002" which I find pretty small if you want to get a good solder fillet. What is the standard annular ring for a 0.050" drilled hole? -----Original Message----- From: Tom Parkinson - Quality System Manager [mailto:[log in to unmask]] Sent: Monday, March 11, 2002 4:33 PM To: [log in to unmask] Subject: Re: [TN] DO-41 footprint size DO-41 is THT.
