I understand what you are asking. I just wanted to ask if you or your company has considered purchasing an AOI or ICT? Perhaps both? Both are valuable tools in the manufacturing process. We lived without our AOIs for quite some time, but in my ca

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,
