摘要:
Pastes are disclosed that are configured to coat a passage of a substrate. When the paste is sintered, the paste becomes electrically conductive so as to transmit electrical signals from a first end of the passage to a second end of the passage that is opposite the first end of the passage. The metallized paste contains a lead-free glass frit, and has a coefficient of thermal expansion sufficiently matched to the substrate so as to avoid cracking of the sintered paste, the substrate, or both, during sintering.

摘要:
The invention relates to circuit boards and to screening circuits and components on such boards from stray rf interference when they are mounted as arrays or stacks of such circuit boards. The circuit boards (12, 14) are individually screened by conductive screening layers (16, 18) as known in the art and the individual screening layers are coupled together by layered interconnects (34) which connect corresponding screening layers (16, 18) of the individual circuit boards (12, 14) together, instead of by vias.
