MMAB Group Upgrades Plating Process
August 30, 2019 | MMAB GroupEstimated reading time: Less than a minute
MMAB Group’s factory in Malmö is undergoing a major upgrade of several process steps. Summer was devoted in upgrading the company’s copper plating which is a critical step in the manufacture of printed circuit boards. The plating process coats holes and patterns with electrolytic copper and this requires a number of chemical baths and plating cells that are powered by high currents.
Production Manager Mats Hansson has worked with Roger Westin as project manager and Mikael Karlsson from Sweco, worked on replacing all rectifiers and control programs for production line. The rectifiers can deliver up to 800 Amps per piece.
Together with the new control program, the process can be controlled more precisely. The upgrade was a significant investment that will secure the production for many years to come.
The picture on the left shows bars with 3x6 rectifiers ready for installation.

Nolan’s Notes: Tariffs, Technologies, and Optimization
10/01/2025 | Nolan Johnson -- Column: Nolan's NotesLast month, SMT007 Magazine spotlighted India, and boy, did we pick a good time to do so. Tariff and trade news involving India was breaking like a storm surge. The U.S. tariffs shifted India from one of the most favorable trade agreements to the least favorable. Electronics continue to be exempt for the time being, but lest you think that we’re free and clear because we manufacture electronics, steel and aluminum are specifically called out at the 50% tariff levels.
