The largest EMS in
the Silicon Valley


Sonic Manufacturing Technologies was founded in 1996 by Ken Raab, Robert Pereyda and Henry Woo. Headquartered in Fremont, California, Sonic provides in-house board layout, prototyping and New Product Introduction (NPI) through full production in as little as five to ten days. Sonic offers a true partnership in building customized solutions based on each of our customers’ unique requirements. A “can do” attitude and “customers first” approach allows Sonic’s industry-leading operation to provide creative solutions and maintain a strong vendor partnership and supply base.

These market forces have tested the EMS industry; and more clearly than ever segregated those who must rely on stable & repetitive products (forecasted, predictable) from those who are responsive & adaptive to the market itself (dynamic, demand-driven).

Interestingly, Sonic has found that by paying attention to the details that make us excel at demand-driven manufacturing our efficiencies have increased on stable & repetitive products. We are cost competitive in both markets; delivering rapidly to your requirements while holding service levels and low liability exposure.

What have we done that makes the Sonic supply chain different? Please read the topic areas below to find out.


Sonic serves virtually every industry in Silicon Valley,’ David Ginsberg, VP of Supply Chain for Sonic Manufacturing Technologies, tells me. ‘Medical, military, aerospace, consumer, industrial sensors, entertainment systems, automotive, drones…you name it, we’ve probably got it in the building.’ 

Sonic is the largest electronics manufacturing service (EMS) in the Valley. To put that into perspective, Ginsberg’s team manages about 30,000 part numbers annually and procures a million parts per week.

But what we’re here to talk to David about today is the first digital supply chain in the electronics industry. ‘This has been a roughly 20-year project,’ he says. ‘Before we even started calling it a digital supply chain, many of us were frustrated that data quality never kept up with the real world. You were constantly fighting your own bad data on top of normal business delays. So we started working on the problem early on.’


Turnkey Solutions

Have you been frustrated with long lead times, slow responsiveness and high E&O billings? Periodically dealt with people that sidestep accountability and results by blaming the forecast (customer)? Does your manufacturing partner pay more attention to performing to their metrics, or yours? Check out this section for what makes Sonic different.

HAL – Automated Supply Chain Solutions™

Sonic Manufacturing Technologies is renowned for its speed and responsiveness in working with customers; frequently working at less than half the lead time of the competition while excelling in quality and delivery. To move this fast requires highly-integrated and automated systems that detect and prevent errors and exceptions while communicating in real time. Come meet the nerve center of our operations…

International Procurement Office

All customers and brand owners are rightfully concerned about component quality and traceability; especially considering the prevalence of counterfeiting and “refurbs” in the industry. Sonic shares these concerns and therefore prefers franchise distribution and factory-direct procurement.

Outbound Logistics

When it comes to shipping; Sonic Manufacturing delivers! (Literally) If you are in the Bay Area our fleet of trucks will be there when you need us. Domestic or International, Industrial or Consumer, OEM, CEM or 3PL; we support your business model. Special packaging, directed carriers and kanban deliveries are all supported.

Reverse Logistics & Depot Repair

When considering the total delivered cost of a product, reverse logistics to an offshore manufacturer is a frequently underestimated item. Are you really going to return it on a boat? Air freight? Include a permanent scrap or cost factor that erodes margins? We are happy to discuss the needs of your business; not just the products awarded to Sonic.
