Here's two more cents... Susan may be referring to pins that are made with a retention feature that hold it in the board while soldering. True pressfit-type pins never require soldering unless there was a mistake made in the hole size during PWB fabrication (hole too large). To repeat, the first step is to review the part spec. > -----Original Message----- > From: bbarr [SMTP:[log in to unmask]] > Sent: Wednesday, October 17, 2001 1:35 PM > To: [log in to unmask] > Subject: Re: [TN] press fit pins > > Are these press-fit connectors you are talking about?
