Most copper crepe will occur in areas where the line density is different, especially where one side is designed to be large copper but the other side has a large empty area.
According to the activity of flux, it can be divided into active (RA), medium active (RMA), inactive (R), water washing (OA), no cleaning (NC)
the process requirements of PCB circuit boards in each industry have gradually improved. For example, gold and copper are used in the circuit boards of mobile phones and computers.
The choice of surface treatment process mainly depends on the type of final assembly components; The surface treatment process will affect the production, assembly and final use of PCB board.
There are many PCB surface treatment processes, the common ones are hot air leveling, organic coating, electroless nickel plating, gold dipping, silver dipping and tin dipping.
Therefore, even for the density is not high, the general number of circuit board, circuit board automatic detection is not only basic, but also economical. In complex circuit board inspection, two common methods are the needle bed test and the double prob
