Achieve More

  1. PCB Assembly - Sunnytech prioritizes quality board assembly and its rework services. We aim for zero defects as our dedicated technicians leverage and apply our multi-industry experience into the work and services we provide.
  2. Box Build Finish Goods - As part of our added value, we offer the option for complete box build assembly and/or final product refurbishment. With three facilities in San Jose, our capabilities extend far beyond board assembly services.
  3. B2B & B2C Order Fulfillment  - By growing our multi-industry experiences and box build capabilities, we evolved into a complete order fulfillment provider. For the past 15 years, Sunnytech has provided full services from board level builds to final product delivery. We've developed our own forward/reverse logistics to cater to client needs for both local and off shore production with delivery. As a result, we earned an exclusive alliance with a tier 1 OEM medical technology company as its fulfillment partner.
