| titleOfInvention | The PCB surface treating agent and surface treatment method for removing brownification layer and the outstanding copper of blind hole |
| abstract | The invention discloses a kind of PCB surface treating agents and surface treatment method for removing brownification layer and the outstanding copper of blind hole, the surface treating agent includes outside sulfuric acid/hydrogen peroxide system, it further include that outstanding copper ingratiates with wetting 0.01~20.0g/L of activator and selective etch 10~100g/L of agent, and its pH value is 1.0~5.0；It wherein hangs copper and ingratiates with wetting activator as alkylol ether surfactant and the composition without hydracid；Selective etch agent is the composition of the salt of aminated compounds and/or aminated compounds, organic phosphine compound and water soluble nitro compound；Hydrogen peroxide stabilizer is the compound for capableing of stable peroxide hydrogen in acid solution, the inorganic agent can not only uniformly remove the brownification layer of blind hole brownification copper sheet, and blind hole can be effectively removed and hang copper, to normal copper face no corrosion, the uniform clean copper foil surface of microetch can be obtained, simple process and dipping and spray, entirely appropriate industrial application. |
