Structure of printed circuit board

The utility model provides a structure of printed circuit board is the printed circuit layer that the printing coating contains the material of metal particle on the insulation board, makes the utility model discloses a structure of printed circuit board compares has better electrically conductive effect in prior art's printed circuit board. Including an insulation board, it has a top surface and a bottom surface, and a printed circuit layer, this printed circuit layer sets up in the at least one side of this insulation board, and the qieyu it is formed with the conducting channel to print the coating on the face. Furthermore, the utility model discloses a structure of printed circuit board simply can make by the mode of printing coating and form the printed circuit layer on the insulation board, compare in prior art with etching mode production printed circuit board pay such as costs such as expensive, high manpower and high pollution, the utility model discloses a structure of printed circuit board's manufacturing has the advantage that promotes industry development and environmental protection simultaneously concurrently.
