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 operating in the gigahertz range, circuit boards now play a critical role,
and must be treated 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 miniature surface mount parts.
Controlled impedance traces, increasing numbers
of required logic voltages, and much smaller trace geometries have greatly increased PCB
complexity.
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 compliance
for FCC EMI and EMC testing requirements.
With designs, we sometimes must specify special dielectric materials, copper and layer thicknesses
and other physical properties for the finished board to achieve a desired functionality. We perform
impedance calculations, crosstalk analysis, and generate test models to determine optimum
circuit trace geometries as well as including proper
transmission line terminations as necessary to eliminate unwanted reflections. New higher speed
digital designs require accurate control of trace lengths to control arrival times based
on the propagation speeds of signals.
Whether its power, analog, digital, RF, High Voltage, or a mixture, choose Telecraft for all of
your printed circuit board layout and design needs.
