Alternative Manufacturing, Inc. (AMI)

Alternative Manufacturing Inc, AMI as we are known, is an Electronic Contract Manufacturing company with locations in Central Maine (Winthrop) and Somerville, MA. The two main services that we provide, is building circuit card assemblies (PCBA) and then taking them to their next higher level, providing a box build. AMI also supports some small volume cable manufacturing and repair work.


AMI is unique in that; our process and equipment is set up in such a way that we can cater to lower volume builds that most startups need. Instead of having one or two long production volume lines, AMI has 11 mini lines, which enables us to do small production runs (down to a single pc) and the ability to ramp up to mid-level production runs, mid-level being 50-100K units EAU. 


The benefit of using AMI as a supply partner for a startup, is that we can support ECO changes and product development easily with any customer. Our team here takes on any project with the intent of exceeding expectations; we offer More... support and guidance to the project with the mindset of making the products more producible, as well as cost effective. 


 Over 85% of the startups that AMI has engaged with over the years, are still with us today as they grow towards pre and full production builds. Let us help you with your project! Less
