Throughout the early years of electronics, the printed circuit board (PCB) was thought
to be merely the mechanical support for circuitry. However, in the new
era of high frequency digital systems, circuit boards are now playing a critical role,
as a circuit component requiring considerably more design attention. In addition,
electronic components have changed with the onset of new packaging
technologies such as ball grid arrays and more mineature surface mount parts.
Controled impedance traces, increasing numbers
of required logic voltages, and much smaller trace geometries have greatly increased PCB
At Telecraft, we've embraced these new trends and have developed special measures for
maximizing the performance of copper and dielectrics. We understand that the PCB
is critical in the elimination of unwanted Electromagnetic Radiation (EMI),
and have developed proven design methods for virtually guaranteeing first pass complinace
for FCC EMI testing requirements.
In other designs, we specify special dielectric materials, copper and layer thicknesses
and other physical properties for the finished board. We perform
impedance calculations, crosstalk analysis, and generate test models to determine optimum
circuit trace geometries as well as including proper
transmission line terminations to eliminate unwanted reflections. Many new high speed
digital designs require accurate control of trace lengths to control arrival times based
on the propagation speeds of signals.
Whether its power, audio, digital, RF or analog, or a mixture, choose Telecraft for all of
your printed circuit layout needs.
