|A "Hybrid", short for
Hybrid Microcircuit, is
a customized circuit containing "un-packaged"
discrete components, such
as ICs, resistors and capacitors.
Significant space savings (see photo), as well
as improved performance
and reliability can be achieved using Hybrid
construction, and as such
has traditionally been used in Military, Space
and Aviation applications
where size, performance and reliability cannot
Many Hybrid Microcircuits are "custom" designed
for specific (Analog
and/or Digital) applications, using "chip"
versions of the packaged parts
traditionally used on printed circuit
boards. Hybrid circuits can
also incorporate custom thick or thin-film
resistors which can be "actively"
laser trimmed for precision circuit
performance. For long term reliability,
most Hybrids are contained within a metal or
ceramic "hermetically" sealed
