Two-layer is cheaper, while the four layers will cost more. なぜなら
Only drilling and 2 silkscreen and 2 solder resist will remain the same.
Compared to four layers, double sided
Primary side | taller stuff, large scale ICs and connectors |
Secondary side | low profile passives (チップ抵抗器 & コンデンサ) and perhaps low profile ICs and diodes, signal transistors |
