| titleOfInvention | Printed circuit board and method of making the same |
| abstract | The invention discloses a printed circuit board and a manufacturing method thereof. The printed circuit board comprises a surface layer, a base plate and a bottom layer which are stacked in sequence. The surface layer is covered with a solder resist ink layer and a laser engraving ink layer. The ink layer is arranged on the same layer, wherein the surface layer corresponding to the laser engraving ink layer is provided with copper skin, and the laser engraving ink layer is laser engraved with hollow points, so that the copper skin leaks out of the hollow points to form a two-dimensional code pattern. Alternatively, the surface layer includes a wiring layer and a laser engraving ink layer, and the wiring layer and the laser engraving ink layer are arranged on the same layer, wherein the wiring layer is covered with a solder resist ink layer. The substrate is an insulating substrate and the substrate is white, and the laser engraving ink area is laser engraved with hollow spots, so that the substrate leaks out of the hollow spots to form a two-dimensional code pattern; or, the substrate is a conductive substrate, and an insulating layer is arranged between the surface layer and the substrate , The insulating layer is white, and the laser engraving ink area has hollow points, so that the insulating layer leaks out of the hollow points to form a two-dimensional code pattern. The invention has the advantages of high production efficiency and high product qualification rate. |
