About us

Founded as a spin-off of a former Ericsson plant, we have capitalized on over ten years of know-how in the mobile telephone industry, maintaining and expanding on this know-how as Trelec.

Given our extensive experience in the mobile telephone industry we are specialists in the soldering process for surface-mounted devices for components up to size 0201 (length: 0.50 mm, width: 0.25 mm). We are also as familiar with using multilayer printed circuits boards (24 layers) as we are with the classic standard control board.

Our catalog of services is designed to provide solutions for real problems, and our capabilities are the result of a continuous effort to apply our resources and qualified personnel toward a shared goal: to offer the best possible service. We use a quality management system that is focused on processes and geared toward the satisfaction of our clients.
