Production of the circuit board mini, visualization, and for optimizing production plays an important role in fixing circuit with the electrical layout.
PCB board, PCB board, aluminum plate, high frequency board, PCB, ultra-thin circuit board, ultra-thin circuit board, printing (copper etching technology circuit board, etc. circuit board makes the circuit mini, visualization , For the fixed circuit of mass production and optimization of electrical appliances play an important role.
First, print the circuit board
Will draw a good circuit board with a transfer paper to print out, pay attention to the sliding side of their own, the general print two circuit boards, that is, a piece of paper to print two boards. In which to choose the best print production board.
Cutting copper cladding
Use the photosensitive plate to make the circuit board full diagram. CCL, that is, both sides are covered with copper film circuit board, the CCL cut into the size of the circuit board, not too large to save material.
Pretreatment of CCL
With fine sandpaper on the surface of the copper oxide layer polished off to ensure that t |
