Daan Although not written for point soldering (actuallly for designing or assesing the possiblility of exclusion fixturing) the following article might be of some help. http://www.datumdynamics.com/exclus.html I would also be happy to look at any board design you have to check for "wave solderability" Regards Fin Finlay Buchan Technical Director Datum Dynamics Ltd Tel +44 (0)1290 426200 Fax +44 (0)1290 426212 Email [log in to unmask] Web Page http://www.datumdynamics.com -----Original Message----- From: TechNet [mailto:[log in to unmask]]On Behalf Of d. terstegge Sent: 18 November 1999 09:34 To: [log in to unmask] Subject: [TN] Design rules for automatic point soldering Hi Technet, For the design of some double sided reflow boards I'm trying to anticipate on using a programmable point soldering machine in the future. This is for the few leaded components that are still on these boards. Could anybody give me some insight on how much free area is needed around the leads ? Are there other special design rules that we should use ?
