| titleOfInvention | A kind of preparation method of rigid-flex board high-precision circuit |
| abstract | The invention provides a method for preparing a high-precision circuit of a rigid-flex board, and optimizes the MSAP process by adding a whitening process and inverse compensation of the resolution accumulation error of an LDI exposure machine. Among them, the whitening process includes washing and removing foreign matter on the surface of the PCB with acid-base solution, which activates the copper surface and reduces copper evenly without increasing the roughness of the copper surface, so as to ensure that the surface of copper ions is easier to escape under the excitation of ultraviolet light waves. surface. During LDI exposure, according to the resolution requirement of the dry film, combined with the resolution of the LDI exposure machine, at least one pixel is reduced to perform inverse compensation of the exposure line size, thereby ensuring the yield of the line. |
