Keystone makes standoff screw terminals that can be soldered to the pcb. Amp/Tyco has some similar press-fit terminals. You can get more current thru the press-fit terminals (no thermal relief on the pads required) AMP Powertap http://tinyurl.com/35oa5f Gary Crowell Micron Technology > -----Original Message----- > From: TechNet [mailto:[log in to unmask]] On Behalf Of Bloomquist, Ken > Sent: Thursday, September 20, 2007 1:52 PM > To: [log in to unmask] > Subject: [TN] Screwing to a PWB > > We have some large lugs that we need to screw to a PWB.
