TO Packages

TO packages are essential for installing various optical and electronic components, from basic circuits to semiconductors. Leads extend from the housing, delivering power to sealed components. Core component performance, like photo and laser diodes, is critical, as environmental factors can cause corrosion, leading to component failure. Leveraging our extensive expertise in hermeticity, Jitai employs encapsulation techniques to safeguard sealed components, ensuring prolonged functionality within microelectronic packages.

QUALITY CONTROL

Over the years, we have perfected our multi-step process to ensure that each component passes rigorous quality and functionality tests, starting from the initial stages before raw materials are even acquired. Upon arrival, raw materials undergo an acceptance sampling method to determine acceptance. If accepted, the entire shipment is thoroughly cleaned, inspected, and any minor imperfections are addressed before warehousing. Following initial assembly and brazing, each product undergoes individual visual inspection and a preliminary hermeticity test, adjusted to meet our clients' stringent air tightness requirements. Subsequently, after the plating stage, each batch undergoes sampling inspection and coating bonding degree analysis. Products passing this stage then undergo a comprehensive inspection, evaluating appearance, construction, plating thickness, and a second hermeticity test. Furthermore, they undergo a series of Factory Inspection trials, including pin fatigue tests, salt spray corrosion resistance tests, and climate simulation equipment analysis for performance assessment. Approved products are individually vacuum-packed with deoxidizing desiccant inserts and additional protective packaging before shipment, ensuring consistent high-quality delivery, reflecting our commitment to maintaining product integrity from our factory to your hands.
