Manufacturing context
Lianchuang Circuits lists double-sided copper-based PCB — catalogue example in its official manufacturing documentation. Base material: Copper-based board. Board thickness: 2.0 mm. Line / space: 20 / 20 mil. Published hole size: 0.8 mm; finished-hole basis requires confirmation. Individual catalogue construction, not the factory-wide minimum line width. The example’s hole value is retained as a fact but not a finished-hole filter. Which metal base, dielectric grade, thermal conductivity and isolation requirements apply to this drawing?
