What this manufacturer makes
KingBrother provides PCB manufacturing, electronic design and assembly services, with the Huizhou manufacturing entity represented in this CRM record. Its official PCB page describes prototype and small-to-medium-batch production. The standard order conditions define ordinary FR-4, a thickness range and copper range; they are separate from the much more aggressive figures on the CAD-design page. This listing uses only the manufacturing conditions, since the ability to design a dense board does not by itself prove that a particular production line can fabricate it.
