Hi I'm trying to plot a LSP profile to reduce void. But I do not have much info about LSP. Does anyone know what are the specific times and temperature of the LSP profile? And are there any ways to eliminate solder void other than changing profile

LSP is 'Long Soak Profile'. See http://www.aimsolder.com/tds/NC_297DX_Sn62_&_Sn63_Solder_Paste.pdf Looks like a variation of the RSS, with you guessed it a longer soak.

ADM, just click on my name and it will give you the E-Mail. I would like to see it. I am currently going the other way with my profiles and almost exclusively using the RTS profiles. Russ

Me too. Check out this months Circuits Assembly. Dage has an interesting article about voiding as a function of surface plating....

Depends on the manufacturer but I know with Kester they strictly tell you once paste dries out it can never be brought back to usefulness. Adding flux will alter the properties of the paste and may affect the final product.

I put a posting in the equipment mart, but I figured I would put one here too. Is there anyone left in the UNITED STATES that has a CP43 left for sale? I am not interested having one shipped from Podunk, or Southern Madagascar. Regards.

I feel the TopazXIIs or the Opal XIIs (both from Assembleon) should be the perfect fit with low cost and high productivity/capability/flexibility. Regards Vinit
