Hermetic Sealing System

Facebook Twitter LinkedIn Email Comments
The AF-8500 hermetic sealing system line includes configurations for lid placement and tacking only, seam sealing only, or a complete lid placement and seam-sealing system.

Loaded with advanced materials and solder preforms, a system can be operated as a stand-alone unit or integrated into an environmental enclosure for a complete closed-loop hermetic sealing process.

Using Miyachi Unitek’s Model HF25 inverter power supply, the AF8500 provides weld pulse shaping, programmable weld spot spacing and a 25-kHz closed-loop feedback rate to achieve high process yields. The innovative programmable weld spot spacing feature enables a user to deliver more or less energy at the corners of parts to greatly reduce corner leaks.

As the microelectronics market requires firms to process a larger variety of parts with decreasing part sizes, the AF8500 offers a number of features to enable quick changeover from part to part along with the ability to accurately pick, place and seal parts down to 3 mm:

• New high-resolution vision system
• Easily adjustable tack electrode assemblies
• Increased rigidity on axis of motion for precise lid and electrode positioning
• Reduced setup and alignment steps
