Blair, A thing to try would be to panelize the board so that the board sees the wave at 90 degrees from what you mention. The terminal block would hit the solder over the whole length at the same time. With a little tweaking of the recipe, you should not get bridges on the blue connector. Good luck, Ioan -----Message d'origine----- De : TechNet [mailto:[log in to unmask]] De la part de Steve Gregory Envoyé : 8 novembre 2007 08:26 À : [log in to unmask] Objet : Re: [TN] Request for posting on your TechNet wall Good Morning Blair and Everyone! I've posted your pictures. They're at: http://stevezeva.homestead.com/files/Term_Board_1.jpg http://stevezeva.homestead.com/files/Term_Board_2.jpg http://stevezeva.homestead.com/files/Term_Board_3.jpg Yes, I have seen something similar to this. Especially with the long terminal blocks. But in my case, both ends would warp upward like a bannana. What we would do was to hand solder a pin at each end, and one in the middle, then use a liquid mask (like Wondermask P)to cover them prior to wave. I know, you don't want to have to put in the extra labor to do something like this, but it solved the issue for us. Steve Gregory -----Original Message----- From: Hogg, Blair K. [mailto:[log in to unmask]] Sent: Wednesday, November 07, 2007 3:34 PM To: Steve Gregory Subject: Request for posting on your TechNet wall <<Term Board 1.jpg>> St <<Term Board 3.jpg>> ev <<Term Board 2.jpg>> e, Can you post these three pictures on your TechNet page? We have seen this problem on some of our termination boards. The terminal blocks lift off the board during wave solder. I haven't watched them go thru the wave, so I can't tell if it is happening when it hits the wave or during preheat. The production supervisor told me the boards went thru with the end with the three terminal connector first. Has anyone else seen this and do you have suggestions on how to keep it from happening?
