VP does work well for BGA Technology but it is not any great improvement on convection reflow. It has been stated in a coulpe of articles that there is no delta T difference with VP from the surface ofthe board and under the BGA. That is not true jus

Do I really need a Vapour Phase Oven or a Nitrogen Oven when soldering PBGA's if my PCB has only 2 to 3 BGA's (ball pitch of 0.5mm to 1.27mm) ? Is the quality of soldering when using an 8-Zone Convective Oven is not acceptable? I have been bombarded

Do you think it would be possible to make a home made vapour phase machine for say $500. What I am think is making an 18 inch square cube type box with a transparrent lid out of s/s or copper. Fit some heating element to the base to heat the liquid

Hi Graham, the MSD level of the component is 3. I am not sure that my customer properly stored the component before the soldering process. And I am not sure that it was dried at all. The customer says they did everything that they had to, but I just

Hi, as you are using Vapour phase reflow what temperature is the boiling point of the solvent you are using ? If it is @ 250 C then you should be getting everything hot enough to melt the ball and solder paste together. If this is the case then your

We are using VPS, but only for high mass assemblies. As the other respondent has suggested if the mass of the assemblies is very low then difficult to control temp. rise times to within the normally accepted parameters. The Rehm equipment does seem

Hi VChauhan, I'll preface this by saying I am no DaveF. Voiding can occur when the flux in the paste boils and vapourises, the expanding vapour needing somewhere to go displaces the paste. So... what we have done in the past: 1) Step the stencil d

We are looking at getting a new inline SMT reflow oven and I have been shown a new vapour phase oven made by ASSCON. It looks very good - just want to know if any one has used one before and can comment. Thanks

Adam: The last one I saw was in communist China back in '98. I have used Lenape machines with freon in the past but am using spray and ultrasonic cleaning techniques since the early 90's. I'm surprised to see someone asking about them! Don
