か反応して基板上に紫色変色を生じる。In general, in the printed circuit board manufacturing process, there are chemicals and chemicals applied to the board during, for example, etching of plated steel foil, solder stripping (operation), solder leveler, fading, baking operations, etc. Due to the action of heat, the printed circuit board discolors to purple or yellow (brown), resulting in a deterioration in product quality.As a result of our investigation into the cause of such discoloration of printed circuit boards, the inventors found that It was discovered that the cause of the discoloration was due to ions in the plating bath when gold-plating the terminals.In other words, when gold-plating the terminals of a printed circuit board, the treatment solution for the board in the previous process contains substances that react with gold. When it is present, the processing solution adhering to the substrate reacts with the gold ions in the plating bath, causing a purple discoloration on the substrate.

化を受けることによるものと考えられる。This purple-colored substance penetrates into the inside of the board, so
It can also be removed by washing with warm water. Further, the yellow (brown) discoloration of the substrate is thought to be due to the strong oxidizing action of the inorganic acid in the solder stripping solution, which causes the substrate to oxidize more than the glass epoxy resin.

にしたプリント基板洗浄液を提供することである。Therefore, the purpose of the present invention is to prevent the discoloration of the board that occurs during the conventional printed circuit board manufacturing process, and to remove the discolored board, which takes a long time using a parser or other tools, as in the conventional method. It is an object of the present invention to provide a printed circuit board cleaning liquid that can omit operations.

去することができる。The alcohol-ether solvent used in the printed disease root cleaning solution according to the present invention penetrates into the substrate, and when washed with water, the purple discoloration can be washed away together with the solvent. On the other hand 1. Since the yellow color of the Nord plate occurs deeper inside the substrate than the purple discoloration, it cannot be removed solely by the permeability of the alcohol-ether bath agent. Therefore, it reacts with the oxidized substrate material and neutralizes it.
By using a water-soluble amine or amide 9 as the primary activator, the yellow discoloration can be eliminated.

より完全に除去される。According to the uninvented printed circuit board cleaning agent, purple discoloration can be removed by soaking the board in the cleaning agent for 1 to 2 minutes at room temperature, or by spraying the cleaning solution onto the board. Complete removal is achieved by soaking or spraying for 1-2 minutes at ~40°C.
