In the circuit board industry, what is the definition of "thick copper plate"?
Because 2oz finished copper thick, hand printed screen printing is not enough to fill the gap between the lines, you must print two resistance welding.
Therefore, in the production of circuit boards, generally encountered 2oz and more thick, it will be in solder solder remarks: thick copper, two screen printing. In order to achieve the line is not red, the line surface welding thickness of greater than 10um effect
The PCB industry of thick copper is not clearly defined, the completion of the general habit of not less than 2oz thick copper plate called thick copper.
