TC7404

  • Paste Type: LTCC
  • Application Method: Screen Printing
  • Substrate: LTCC
  • Metal: AgPd
  • Application: LTCC
  • Description: TC7404 is a fritted conductor material, with a silver/palladium ratio of 6:1. It is ideal for use as a resistor termination, and exhibits excellent wire bonding properties with heavy aluminum wire. TC7404 was specifically developed for use as a conductor on Heraeus tape system of CT700 Series, CT707, CT708 and CT800 Series. It exhibits a particularly good adhesion when (post-) fired upon these glass-based tape substrates.
  • Key features: Good solderability and leach resistance#Solderable on CT700 Series, CT707, CT708 and on CT800#Series Compatible with HERAEUS resistors#Excellent aluminum wire bond properties
  • Process Temperature: Fire at 850-865 °C (peak) for 10 minutes, and with a total firing cycle time c. 30-60 minutes.
  • Film Thickness : 11-15 um
  • Viscosity: 30-50 Pas (25 °C, D = 100/s)
  • Conductivity: ≤ 20 milliohms/square (FFT: 12 um)
