We will continue to innovate and invest in new automation solutions for programming and test. V-TEK’s existing programming business let us accelerate Programming-as-a-Service.

With broader end markets, a growing service business and meaningful new scale, we believe there is the potential for significant upside ahead and look forward to participating in it as shareholders.”

“Each of our three companies brings a distinct strength, and together they are covering the data provisioning supply chain,” said Mitch Jacobs, President, V-TEK, Inc. and, following the acquisition, Senior Vice President, Data I/O Corporation.“V-TEK’s handling, test, inspection and packaging systems, A&J Programming’s service expertise and Data I/O’s programming and security technology fit naturally together. That combination lets us expand our solutions with modular and customized systems, flexible service offerings, and global distribution andon-site support. It’s a stronger offering for customers and a real growth platform for the business.”
