Laser Hermetic Sealing

We are market leaders in the provision of specialized laser hermetic sealing. Laser hermetic sealing is another fusion welding process that employs laser welding technology. Medical, semiconductor, defense, aerospace, transportation, power generation, and construction are some of the common industries, which require laser hermetic sealing process for products.

• Hermetic seals, which offer 100% protection against moisture, are produced using high temperature sealing techniques
• In the high temperature sealing technique, a high-energy laser beam is directed on the materials to be processed to raise their temperature and transform them into liquid states. Molten materials thus combine together and then cool rapidly to produce the hermetic seal
• Accurate sealing material selection and proper weld configuration are crucial for optimizing the final yield
• Low leak rates, low heat input, high consistency, and higher yields are significant advantages of hermetic sealing

Application Advantages

Parts are generally laser sealed after vacuum baking to less than 1 ppm of oxygen and moisture. This improves the performance characteristics of parts compared to that of any other conventional epoxy, solder and mechanical seals. Our welding processes use minimal heat so that sensitive, precision components are protected from thermal damage likely to be caused by methods using higher temperatures.

Approved MIL Specifications, Certifications and Accreditations

Our laser hermetic sealing process complies with ISO 9001:2000 standards. We follow the military standards MIL-PRF-38534E and MIL-STD-883 in our laser sealing and laser detection processes. We also own an aerospace quality system AC7004 certification from Nadcap.

Laser Hermetic Sealing Equipment (multiple machines) / Services

Our CNC-controlled laser glovebox workstations are capable of monitoring and controlling an inert atmosphere (comprising gases such as Argon, Helium or Nitrogen) with moisture and oxygen levels maintained below 1 ppm. Standard real time batch reports prove this. Our laser hermetic sealing equipment portfolio comprises ovens that operate at temperatures of about 200 degrees centigrade and less than 200 microns vacuum. Fluorinet-based gross leak detection up to 10-3 cc.he/sec and mass-spectrometer helium fine leak detection of up to 10-11 cc/he sec are offered as part of our laser hermetic sealing services to ensure that all your diverse sealing needs are fulfilled.
