VIP98N settings | 7 December, 2007

Hi,

Could you guys verify my BTU VIP98N oven settings for lead free process. At the moment as my standard profile im using these settings

140 160 180 207 205 220 257

same temps for bottom and speed 50cm/min.

Has anyone got same oven and could tell me what settings they using? Also what you think about my settings.

Also im getting crystalized yellow flux residue on solder joints and around them. Is it profile related? Im using indium 5.1at no clean paste.

Thanks

Marcin

Try profiling your board. How can anyone say your profile is good without knowing the board size and specific parts on it.

Hi,

I am using a 7 zone Conceptronics oven and Indium 3.1 lead free clean paste. Our profile is as follows, 130 140 150 180 200 240 260 with a belt speed of 36 inches per minute. I dont know if that will help you out though...

First of all you need to profile your board.....no one is going to be able to tell you what setting to run without know the product and components. You are also going to want to check the paste spec. against you temp. ramp/rise rates. Just guessing you are not meeting them if you have not profiled your board. I would say the yellow residue is from that.

Hope this helps.
