Metalized soldering assembly

Meetcera supplies precision metallized ceramic components in aluminum oxide ceramics for the military, medical, and aerospace industries. Through spray, needle, and brush coatings or screen printing our capabilities allow us to metallized on flat, cylindrical, and complex ceramic bodies. Moly-Manganese is the typical base coat materials used for metallization.

Metallized Ceramic Insulators Features:

1. The ceramic material is with even texture, each batch has stability quality and flexural strength.
2. Metal layer is dense, constant, smooth and good weldability.
3. Excellent electrical insulation, low dielectric constant, good abrasion, and corrosion resistance.
4. High tensile strength, good airtightness to meet the requirement of the high-frequency, high-power and safe electrical components.

Metallized Ceramics Applications:

  • Ceramic Feed-through Insulators (for hermetic electrical pass-throughs)
  • Ceramic Headers and High-Power Receptacles
  • Insulating Discs, Rings, and Cylinders
  • Precipitator Products and Power Switches
  • Traveling Wave Tubes and Vacuum Interrupters
  • Windows, Power Grid Tubes, and X-ray Tubes

These applications benefit from the components’ ability to maintain integrity in harsh conditions, such as vacuum electronics, RF/microwave devices, sensors, and power modules

Metallized Ceramics Joining types:

  • Ceramic + Mo/Mn Metallized + plating Ni
  • Ceramic + Mo/Mn Metallized + plating Ag
  • Ceramic + Mo/Mn Metallized + plating Au
  • Ceramic + printing Ag
