We had a busy weekend in Chicago where we attended KiCon 2019. On Friday 26th and Saturday 27th of April, Sierra sponsored the first KiCad users conference. Or, as KiCon said it best, “The first and the largest gathering of hardware developers using KiCad.”
From signal integrity to roughness of the copper and stack-up design, here are a few PCB design tips you could use:
- Insertion loss and attenuation
- Signal integrity for automotive electronics and IoT
- Fine lines
- Copper for ground and power planes
- Roughness of the copper
- Stack-up design
- Work with your fabricator
The topic of clock jitter performance seems to be a current focus of clock, ADC, and power supply manufacturers. The reasoning is clear; clock jitter interferes with the performance of digital circuits including high speed ADCs. High speed clocks can be quite sensitive to the “cleanliness” of the power they receive, though quantifying the relationship takes some effort.
Sending rockets to space is not science fiction anymore. In a few years, we will even all pack our bags to go to Mars on vacay with Elon. You still need the best printed circuit boards to make it up there in one piece, though.
Low power, high performance circuits are often plagued by power supply related issues. This common occurrence is frequently due to mythical (or misapplied) rules-of-thumb.
When customers want to design HDI boards that are as compact as possible, there is often very little reliable guidance from the chip vendors. Heed the warnings of Texas Instruments: Consult board manufacturers from the start of any projects involving BGAs with a pin pitch of 0.4 mm and smaller.
