<strong>Effective</strong> <strong>PCB</strong> <strong>Design</strong>:<br />
Techniques to improve performance<br />
Schematic must be evaluated during layout<br />
• Pin assignment to connector signals<br />
Ideal Connector Pin Assignment:<br />
PGSGSGSGSGP<br />
GSGSGSGSGSG<br />
– Not exactly economical or practical<br />
More practical and fewer ground pins:<br />
SSSGSSSGSSP<br />
SGSSSGSSSGP<br />
– Each signal is still only 1 pin spacing from Ground<br />
