Here is a question about this article: The hole walls for boards with two or more layers can be made conductive and then electroplated with copper to form plated-through holes. These holes electrically connect the conducting layers of the PCB. For multi-layer boards, those with three layers or more, drilling typically produces a smear of the high temperature decomposition products of bonding agent in the laminate system. Before the holes can be plated through, this smear must be removed by a chemical de-smear process, or by plasma-etch. The de-smear process ensures that a good connection is made to the copper layers when the hole is plated through. On high reliability boards a process called etch-back is performed chemically with a potassium permanganate based etchant or plasma. The etch-back removes resin and the glass fibers so that the copper layers extend into the hole and as the hole is plated become integral with the deposited copper.
What is the answer to this question: Etch-back removes glass fibers and what other material?

So... resin

Here is a question about this article: The portion of the city south of the James River is known as the Southside. Neighborhoods in the city's Southside area range from affluent and middle class suburban neighborhoods Westover Hills, Forest Hill, Southampton, Stratford Hills, Oxford, Huguenot Hills, Hobby Hill, and Woodland Heights to the impoverished Manchester and Blackwell areas, the Hillside Court housing projects, and the ailing Jefferson Davis Highway commercial corridor. Other Southside neighborhoods include Fawnbrook, Broad Rock, Cherry Gardens, Cullenwood, and Beaufont Hills. Much of Southside developed a suburban character as part of Chesterfield County before being annexed by Richmond, most notably in 1970.
What is the answer to this question: Along with the affluent, what is the socioeconomic class of the inhabitants of the Southside?

So...
middle class
