Achieve More

  1. PCB Assembly - Quality board assembly and its rework service is one of the priorities of Sunnytech. We aim for zero defects and our dedicated technicians leverage and applies our multi-industry experience into our work and services we provide.
  2. Box Build Finish Goods - As part of our value add we offer our customers the option for complete box build assembly and/or final product refurbishment at Sunnytech. With three facilities in San Jose our capabilities extend far beyond board assembly services.
  3. BtoB & BtoC Order Fulfillment  - Our multi-industry experience along with box build capabilities naturally led us into a complete order fulfillment provider. For the last 15 years Sunnytech had been building from board level to final delivery of products. We've developed our own forward/reverse logistics catering to our customers needs for both local and off shore production with delivery. This led to an alliance with a tier 1 OEM medical technology company to exclusively use Sunnytech as its fulfillment partner.
