Just Ask Happy: Two-Layer Low-Speed PCBs


Reading time ( words)

In our latest survey, we have asked that our readers send in questions they might have for Happy Holden, and quite a few of them took us up on it! The questions that were posed run the gamut, covering technology, the worldwide electronics fabrication market, and everything in between. Enjoy.

If you would like to participate in this ongoing survey, please follow this link.

The following is today's question and Happy's answer:

Q: Why do many two-layer boards work in low-speed applications, signal integrity-wise?

A: Two-layer boards, properly designed, will even work in high-speed applications! Even a single-sided board will. If the signal rise times are slow, signal integrity does not enter in the solution.
