Printed Circuit Board Layout and Manufacture
Analog Integrated Circuits
An important parameter when specifying traces on printed circuit boards is the ounce rating of the copper used. “1 ounce” copper is very common for general-purpose work. Explain how this “ounce” rating is defined, and why you might want to use “2 ounce” or “4 ounce” copper instead of “1 ounce” for certain traces on your board designs.
A solder mask is a very important feature on professional-quality printed circuit boards. Explain what a solder mask is, and why it is so important.
