Description

technical field [0001] The invention relates to the field of LED printed circuit boards, in particular to an LED double-sided circuit board with low-resistance carbon oil filling holes and a conduction processing method for the carbon oil filling holes. Background technique [0002] At present, the traditional conduction process of LED double-sided circuit boards is PTH\polymer conductive adhesive (film) plus full-board electroplating or graphic electroplating to realize conduction and connection of double-sided lines. This process technology has a large amount of electroplating chemical waste gas and wastewater discharge, which is serious. It pollutes the environment, and at the same time, the demand for metals such as copper and tin is large, and the cost is high. In addition, using the existing electroplating technology, there are problems of glue leakage through the conductive vias and slow corrosion of the ambient air moisture during the assembly and production of the L...
