Most Honeywell
circuit boards are designed and constructed on CEM3 and FR4 boards. These
Printed Circuit board (PCB) materials provide lot of application advantages or
benefits of which notable of them are
a.
Easy dissipation of heat
b.
Ability to support some metal cores as well as
most heat sinks
It should
however be stated here that while most PCB manufacturers make use of these
types of boards due to their benefits, there are still some applications which
require that the PCB design and construction should made to support lot of metallic components. Such boards will
need to be metallic to be able to do the stated functions. This is why we will
see some Honeywell PCB boards that are aluminum materials; being the most used
metallic board for construction of PCB.
The aluminum PCB
is also known and called metal base PCB and is constructed from alloy plates of
Al-Mg-Si (Aluminum, Magnesium and Silicon). The base of this alloy plate is
laminated and copper foil circuit strata or layers used to cover it. Some of the benefits of this metal base PCB
are
1. It
provides good electrical insulation
2. It
possesses good thermal or heat radiation potential
3. Its
machining performance attributes is very high.
