Q: What is a Thick Film Hybrid(TFH) circuit?

A: A thick film hybrid is a circuit created on an Alumina substrate through a controlled screen printing process. This circuit is then fired at high temperatures yielding conductors and resistive elements

Q: Why would I use a TFH?

A: Yes, to mention a few

• a reduction in physical size,
• tight tolerances can be achieved on "out of the norm" values,
• reduced component inventory for "select on test" circuits

Q: What is Active or Functional Trimming?

A: The circuit is powered up with the desired output monitored and trimmed by the laser. This output can be a voltage, amplitude or frequency.

Q: How are these circuits manufactured

A: The circuits are manufactured in a controlled environment with printed thick film paste much like the printing process in fabric making industries
