Power Packages
Jitai builds hermetic power packages for an enormous range of applications. These packages are engineered to be extraordinarily strong, perform consistently in challenging environments, and meet strict reliability requirements. Power packages are used in applications where heat dissipation is crucial. Some typical examples are; power thrusters for aviation and space, power converters and motor drives, along with switch mode power supplies and power hybrid circuits. Feedthroughs are another important consideration for power packages. We manufacture both glass-to-metal-seal (GTMS) and ceramic-to-metal-seal (CTMS) feedthroughs. Package designs are fully customizable or choose from our catalogue of open-tooling options.

QUALITY CONTROL
Over the years we have finely tuned our multi-step process of ensuring every single component passes all quality and functionality tests, tests that begin even before raw materials are on-boarded. At this first stage, each shipment of raw materials undergoes an acceptance sampling method assortment which makes a determination about whether to accept the material. If such a determination is made, the entire shipment is cleaned, a full inspection is performed, minor imperfections are buffed and polished, and stock is then warehoused. The second stage is conducted immediately following the initial assembly and brazing stages. Every single product undergoes an individual visual inspection followed by a preliminary hermeticity test. For hermeticity we utilize a helium leak test that is adjusted to meet the exacting air tightness requirements of our clients. Following the plating stage, each batch undergoes a sampling inspection and a coating bonding degree analysis. Products that make it past this stage are then subjected to full inspection which includes scrutiny of appearance, construction, plating thickness, and a second helium tracer gas hermeticity test. Finally products are put through the full range of Factory Inspection trials. These include pin fatigue tests, a salt spray corrosion resistance test and analysis that relies on climate simulation equipment to test product performance. Once products are approved, they are individually vacuum-packed with a deoxidizing desiccant insert and ensconced in additional protective packaging before being shipped out. These efforts guarantee that every Jitai product delivered to you is of the same high quality as when it left the factory.
