About us

Since 1986, Ironwood Electronics has been the go-to source for advanced adapters, sockets, and modules. Our adapters convert package and pitch between devices, our modules offer complete fully tested assemblies for component replacement and upgrade, and our sockets allow for complete component and assembly testing – from new silicone characterization and validation, all the way thru burn-in and high volume automated testing – always with the highest performance and lowest possible footprint in the industry.

Now in its 37th year with over 65 employees, Ironwood brings a combined knowledge of hundreds of years of engineering and manufacturing expertise, all under one roof in our state of the art 25,000 sq. foot facility just outside Minneapolis, Minnesota. Combined with our recent acquisition of the Grypper socket line, our continuous new product development demonstrates our on-going commitment to both our customers and the industry we serve.

While this website is extensive with many thousands of part numbers, it is only a brief introduction to our various categories and vast product range. With more than 10,000 standard products, and even more custom solutions, there are very few challenges we have not come across – we welcome your next challenge!
