I want to know the answer to the following question:
What non-professionals might use immersion etching, since it's the easiest way to make a PCB?
All the background I'm provided with is that "The simplest method, used for small-scale production and often by hobbyists, is immersion etching, in which the board is submerged in etching solution such as ferric chloride.". Is that enough to answer the question?
Answer: yes
