183C or 361 F -----Original Message----- From: TechNet [mailto:[log in to unmask]]On Behalf Of Karen Walters Sent: Monday, August 30, 2004 1:56 PM To: [log in to unmask] Subject: Re: [TN] TAMURA Solder Paste Yes but they allow to 240 peak temp which is high. 220 should be max and the liquidus is 179 deg C not 200. This concerns me. I think they are recommending one profile for all boards.
