Printed circuit board manufacturing technology is a very complex, comprehensive high processing technology. Especially in the wet process, the need to use a lot of water, which has a variety of heavy metal wastewater and organic wastewater discharge, the composition of complex, more difficult to deal with. According to the printed circuit board copper foil utilization rate of 30% to 40% of the cal...

Single panelOn the most basic PCB, the parts are concentrated on one side and the wires are on the other side. Because the wires only appear on one side, the PCB is called single-sided. Because there are many strict restrictions on the design of the single-sided board (because only one side, the wiring can not cross and must be around the path), so only the early circuit to use such a board.Double...
