Lead-Free Knowledge Base

AIM has been developing lead-free alloys and researching the subject of lead-free soldering since the 1980s, and we have accumulated a great deal of knowledge on lead-free alloys, processes, and  the issue in general. We would be happy to work with your company on the implementation of a lead-free process and to share the vast data and experience on lead-free alloys that AIM has accumulated over the years. Please feel free to contact AIM at anytime so that we may be of assistance during this often-complicated transition period. No matter what the application, AIM has the lead-free products and process knowledge required to help your company in the transition to lead-free soldering in the most logical and economical ways possible.
