Final assembly of hybrid printed circuit boards
Hybrid circuits — Manufacturing

The components used in hybrid circuits, as for any electronic function, can be divided into two classes: passive and active.

Passive components are either printed directly (usually resistors), or transferred in the form of blocks. These two options can be combined to overcome the specific drawbacks of each technology. For example, the use of transferred resistive blocks is possible:

• on thin-film circuits for high-value resistors (a few tens of kiloohms and above);

• on thick-film circuits for low temperature drifts (< 50 · 10 ^{– 6} / °C).
