Hello, I am wondering if anybody has process experiance of designs which use the above. I understand that the filled via is an excellent thermal cnductor, which is great from a design point of view, but how do these solder through the reflow ovens

Contax are not always the most responsive of companies in the UK. Besides, you get a lot more for your money with BTU Pyramax's or Vitronics Soltec and very good service.

Are there any methods for mounting ball grid arrays without a reflow oven? More and more chips are coming in the format and as a student I am not interested in production line quantities.

I am looking for images of solder paste defects like Past stringing, paste gorging and dog ears. I would also like to have the avi file to show how tombstoning happens in the reflow oven. Thanks Bob

Hello we are having a problem with an Unitherm 500 reflow oven from Vitronics. the conveyor is not responding to the system, the speed is out of control, it seems to be alerted. Does any one know what is going on. your help is greatly appreciated. Re

Defects will result, Your cooling rate is affected because the hot air is not circulated properly. Outgassing will appear and you'll have pin holes / blow holes, disturbed joint etc. Correct me guys if i'm wrong. Thanks

The 2 issues are: -1 Enough flow to keep all fumes from reaching people. -2 Consistent amount of heat removal to keep the temperature steady. If the 45 CFM is steady and keeps all fumes away from people all is well. Jerry

Its been my experience that a "dot" of glue on the center of the part is needed for "barrel" type components.

Because they haven't made copies of Fuji and MPM equipment yet....unlike reflow ovens and waves.
