About Yiyang Industrial Ltd.
Who We Are
Founded in 2014, Shanghai Yiyang Industrial Co., Ltd. is a vacuum industry specialist and the first domestic high-tech enterprise to combine maintenance, leasing, sales, system integration, R&D customization, and core-technology OEM under one roof.
Our R&D team includes 2 PhDs, 5 Master's, and 9 Bachelor's, with engineers drawn from Huawei, ZTE, and Spreadtrum. Maintenance is led by senior technicians trained at original equipment manufacturers, each with six or more years of field experience. We reinvest at least 30% of annual revenue into R&D, and hold our service standards above OEM repair benchmarks.

What We Do
Manufacture vacuum detection equipment and accessories
We design and produce our own-brand Sunvac series, launched in 2016 and engineered to perform on par with leading international brands. In-house PCB design and solution customization let us tailor instruments to specific process requirements in semiconductor, battery, and aerospace environments.
Repair vacuum detection equipment
Repairs are handled by senior factory-trained technicians averaging six-plus years of hands-on experience. Our flagship PCB Repair Service restores boards that most service centers replace outright. Every job is delivered to a service standard that exceeds OEM repair specifications.
Sell vacuum detection equipment, accessories, and consumables
We stock a full lineup of helium leak detectors, leak standards, sniffer and spray guns, vacuum gauges, and matching consumables. Inventory spans INFICON, Pfeiffer, Leybold, KYKY, and Edwards, giving procurement teams a single source across major OEMs. Lead times stay short because we hold the parts our customers actually order.
