The Chemical Connection: Chemical and Equipment Control of High-density Circuits, Part 2

08/27/2024 | Don Ball -- Column: The Chemical Connection
In my June column, I discussed how much control was needed for high-density circuits rather than what was thought necessary. I concentrated on cupric chloride and alkaline etch issues and equipment, since the etching step in the circuit board manufacturing process is one of the most critical areas where small changes in etchant parameters can have a large effect on the final product. The intention was to continue in the July issue with less critical process steps, such as developing and stripping. However, I got distracted by a specific control issue for alkaline etch, specifically controlling your alkaline etch process when you’re not etching a lot of copper. So, this month, I’m picking up where I left off in June.

Beyond Design: Does Current Deliver the Energy in a Circuit?

07/25/2024 | Barry Olney -- Column: Beyond Design
In circuit theory, we learn that current flows in a closed loop, returning to the source via a conductor pair. This flow of current provides power to the load, and energy transfer occurs as described by Ohm’s law (P = VI). Conversely, in electromagnetics theory, we discover that current does not provide the power in a circuit, but rather the energy wave is guided by the conductor to power the load, according to Maxwell’s equations.
