S3 Test Eases Laminate Selection

S3 Test Eases Laminate Selection

For her MIT master’s thesis in engineering, Michelle Rybak investigated signal loss over frequency of six different PCB laminates, with special attention to distinguishing the resistive loss by the copper from the loss caused by dielectric absorption. er research...

Making Sub 3/3 A Reality

Mythbusting the Semi-Additive Process Prudent PCB designers used to have good reasons for avoiding trace widths and spaces smaller than 3 mils beyond very short spans. But the 3 mil limitation is now becoming a thing of the past, thanks to the use of semi-additive...

A Tale of Two Materials

Since the turn of the 21st century, there has been intensive research toward the development of embedded optical channels for transporting high-speed digital signals within printed circuit boards. I suspect that an alternative to copper traces might be commercially...
