About Us


Founded in 1998, our two-plus decades crafting high quality hermetic packages and components make Jitai one of the most experienced manufacturers of these products in China. We specialize in metal packages, glass-to-metal seals, and related components. We are capable of controlling the entire production process in part because of our in-house plating department and seven step quality control methodology. Our R&D department is constantly working to innovate and add to our existing product lines, efforts that have been recognized with nearly two dozen domestic patents and hundreds of satisfied clients. At home we have been officially designated a National High-tech Enterprise. Our 200 employees along with a core technical team of over 50 engineers, technicians, and researchers have at their disposal a state-of-the-art facility that ensures quality is our central guiding principle from product conception to manufacturing.

Jitai’s Quality Control Methodology

From the onboarding of raw materials to the moment our products arrive in the hands of our clients, Jitai employs an overlapping system of quality assurance and quality control methodologies that ensures our products meet the exacting standards of the hermetic package industry.

Onboarding of Raw Materials

Inspection of Raw Materials

Quality assurance begins before raw materials are even warehoused. At the acceptance sampling method stage, materials are randomly selected for quality inspection (after which a determination is made about whether to onboard the shipment), if such a decision is made the entire shipment is then cleaned, a full inspection is performed, minor imperfections are buffed and polished, and stock is then warehoused.

Assembly and Brazing

Complete Visual Inspection and First Hermeticity Test

Following the initial assembly and brazing stages, each product undergoes an individual visual inspection followed by a preliminary hermeticity test.


Sampling inspection

Coating bonding degree inspection.

Finished product inspection

Full product inspection which includes scrutiny of appearance, construction, plating thickness, and a second helium tracer gas hermeticity test.

Factory Inspection

Pin fatigue test, salt spray corrosion resistance test and climate simulation equipment that tests product performance

Packaging and Transportation

All products are individually vacuum-packed with a deoxidizing desiccant insert, then wrapped in a layer of bubble wrap. These efforts guarantee that every Jitai product delivered to you is of the same high quality as when it left the factory.
