Grinding methods vary according to the grinding object (product) and the required quality, from hand grinding to grinding, polishing, grinding with grinding wheel, felt grinding, electrolytic grinding and other methods. Requirements for quality include gloss, surface roughness, cleanliness, removal of surface film, etc. It is generally accepted that grinding has many proprietary techniques. The selection of grinding materials (abrasives, processing fluids, grinding tools, etc.) that match the material of the grinding object (product), as well as the selection of the shape of the suitable grinding object (product), and the selection of grinding equipment and operations that meet the required processing accuracy require profound knowledge and experience. In the past, optical parts manufacturers regarded grinding skills and technicians as precious, and proprietary technologies did not leave the house. Even now, the quality of grinding products depends on the skill and experience of the technician.
So, what role does grinding play in the circuit board manufacturing process? The circuit board is made after a number of sections, almost all sections before and after grinding, and each section of the grinding object (hereinafter referred to as the board) shape, material and quality requirements are not the same, so the use of different grinding methods is inevitable.
Although grinding is not used for drilling, electroplating, graphics transfer and other main processing, it has a great impact on the quality of the circuit board, and sometimes even an important section that induces fatal shortcomings.
In recent years, the difficulty of grinding increases with the microrefinement, high density, and the coexistence of thick and thin graphics of circuit boards.
The drilling and shape processing of the circuit board manufacturing process is "cutting", and the surface treatment before and after electroplating and graphic transfer is "grinding". However, the grinding of each section requires the addition of a moderate "grinding" process. Therefore, the grinding and grinding of the circuit board manufacturing process is not continuous, and is generally called "grinding".
