<strong>Effective</strong> <strong>PCB</strong> <strong>Design</strong>:<br />
Techniques to improve performance<br />
<strong>PCB</strong> Signal TRANSMISSION LINE Routing<br />
• Route power and ground traces as close as manufacturing allows<br />
Internal and customer separation requirements<br />
<strong>PCB</strong> Fabrication limits for chosen supplier<br />
– Yes Yes, you o do need to know kno what hat the ssupplier pplier can man manufacture fact re<br />
– Can have big impact on <strong>PCB</strong> cost<br />
• Small changes in routing can have a large impact on performance<br />
• Component placement is critical<br />
Staying within lumped distance<br />
– Reduces component count<br />
– Reduces system cost<br />
– Improves EMC performance<br />
• Minimize the VOLUME of the Power TRANSMISSION network<br />
