Hi, Does anyone have any experience of cleaning lead free solder paste residues off pcbs in a vapour degreasing process using Ensolv Ionic ? Any guide as to the best cleaning cycle would be appreciated. thanks

Dear Rick , thanks for your reply. It is very helpful. I'll get chance to try the Ensolv in a lab next week to see if we can remove the paste residues. Thanks again

Alcohol won't do much for the rosin residue, you'll have to scrub which isn't good on your QFP. Can you clean the assemblies before removal? A solvent such as Ensolve or Axarel would be effective on rosin.

When we hear the words 'flexible circuit' and 'delamination' in the same sentence, we think: * Excessive reflow temperature. * Entrapped moisture. Boardhouse: I hope this is a step towards redemption.

Hi Graham, I've worked in the industry selling EnSolv, Lenium, and now ENTRON solvents, which are all based on stabilized NPB. These solvents do not always clean the no lead pastes. The problem is that the pastes are becoming more like adhesives,

Our latest designs are flip chip on flex based and we have issues with delamination/blistering. We know it is related to our vapor solvent (n-Propyl Bromide based) attacking an inner layer adhesive. Has anyone else ever heard of something like this?

I started using Ensolv about a year ago. It's the best solvent I've found yet for cleaning uncured adhesive. It's also recommended for board cleaning, although I haven't used it on wet paste. As the name implies, its environmentally friendly with n
