Corwil Technology Acquires Viko Test Labs

MINNETONKA, Minn.  (March 11, 2014) — CORWIL Technology Corporation (“Corwil”), a portfolio company of Tonka Bay Equity Partners (“Tonka Bay”), announced the acquisition of VIKO Test Labs, a division of Infiniti Solutions.  This strategic acquisition enhances Corwil’s market position as a true OSAT (Outsourced Semiconductor Assembly & Test) leader, with the addition of electrical, environmental, and mechanical test services.  Corwil joins an exclusive list of domestic providers with both assembly and test operations located in the United States.

In 2013, Tonka Bay partnered with industry veteran, Matt Bergeron, and co-founders Rob Corrao and Finn Wilhelmsen, to invest in Corwil.  Based in Milpitas, California, Corwil is a leading provider of semiconductor assembly and test services.

“The addition of VIKO’s testing capabilities, equipment and engineering expertise will allow Corwil to provide our customers with a full turnkey back end solution,” said Matt Bergeron, Corwil President. “The new Corwil Test Division (CTD) will provide our customers with optimum test solutions and services, by aligning their product requirements with the correct equipment and test program development services, and by reducing the customer’s manufacturing cycle and time-to-market.”

Molly Simmons, Principal of Tonka Bay and a Corwil Board member added, “We are excited about Corwil’s growth potential as this acquisition strengthens the company’s position as a strategic manufacturing partner to its customers in high reliability end-markets including medical devices, commercial and military/aerospace.”
