| titleOfInvention | Pretreatment composition for chemical plating |
| abstract | The invention discloses a pretreatment composition for chemical plating, which comprises the following components: an acid free of halide ions, a source of halide ions and an unsaturated carboxylic acid. According to the invention, the acid without halide ions, the halide ion source and the unsaturated carboxylic acid are compounded, so that the prepared pretreatment composition for chemical plating can effectively remove palladium adsorbates and precipitates in a non-plating target area, thereby improving the phenomenon of 'diffusion plating' during chemical plating and improving the yield of fine circuit printed circuit boards. |
