Annular ring is the amount of copper left and surrounding the hole after processing. This measurement is taken from the edge of the hole to the edge of the land at the thinnest part. To ensure a robust design, we must design efficient annular ring for PCB interconnections. From Ryan Miller's experience, annular ring design is a misunderstood aspect of printed circuit board (PCB) design. Not because it is complex; it is a dry subject with a few moving parts.
The chip shortage is by no means over, with estimates expecting it will last into 2023. Some could see it taking even longer, such as Intel CEO Pat Gelsinger, who expects it to see shortages into 2024 due to those now impacting electronics production equipment. But if there’s any bright spot to be had, it’s that a crisis often leads to long-term solutions. In this case, it’s the increase in government funding for semiconductor production in the United States. Once the CHIPS Act proceeds, we can significantly accelerate building semiconductor fabs in the United States and work toward preventing future chip shortages that would put us back into our current situation.
Higher system speeds have necessitated consideration of signal propagation delay and quality not just within electronics, but through wire harnesses. Tighter form factors have minimized the typical “board in a box,” where...
One of the most amazing advances in PCB manufacturing technology has been the advent and usage of laser direct imaging (LDI) technology. For PCB manufacturers, this technology has been a game changer, helping to reduce costs, speed...
