Rototyping Techniques:things To Know Before Pulling The Trigger

摘要

Prototyping has become far more difficult than it was in the old days. For one thing, electronic components have gotten smaller; an IC can now be the size of a peppercorn or a grain of sand. As a result, you must take measures to illuminate, observe, and handle these tiny parts. Making things even more difficult is the fact that many modern circuits operate at high frequencies, so you canrnno longer just solder wires between components; you must connect those circuits with controlled impedances using traces. Thermal management brings more challenges.rnTo prototype a PCB (printed-circuit board), you need lamps, tweezers, magnifiers, microscopes, and solder stations. Once you have collected this equipment, you are ready to build your prototype. Remember to take special precautions in the design andlayout of analog boards, however (Reference 1).
