Supply of copper conductive paste, conductive copper paste (copper conductive plastic, conductive copper paste) is a single component can be soldered directly to the conductive paste, also applies to SMD technology and multi-connection point of printing. Can be welded directly, without additional process; by hot air leveling or hand welding repair, good adhesion. Applicable to all types of rigid printed circuit board PCB, single plate, double plate, plywood can be applied, good adhesion, printing, and can directly solder, the use of flexible.
