. Corrosion is another issue that manufacturers should consider when making PCBs for aerospace applications. The relatively low cost of copper and high electrical conductivity make this metal a common material in PCSs

. However, the selective wave solder process uses a product-specific pallet to shield the SMT components on the bottom side of the board, with apertures to expose the PTH components

: Copper, resin, and glass are used, with one-third of copper coming from Chile/Peru, the top three resin producers are US/Germany/Japan, and China is the top glass producer, but prices vary slightly globally. Comparing Costs

“ The minimum board edge to any feature - component, via, trace, copper pour is 40 mils (1.0 mm)”. I have a hard time with IPC spec’s and where to find out things like that. I have been using .040 for planes and .020 for traces
