Silver plating method for ceramic for ceramic filter
The invention belongs to the field of silver electroplating, and particularly relates to a ceramic silver plating method for a ceramic filter. The ceramic silver plating method for the ceramic filter comprises the following steps: performing oil removal, coarsening and palladium activation on a ceramic substrate, and then performing chemical nickel plating, copper electroplating and silver electroplating; the main component of the ceramic substrate is magnesium titanate and/or calcium titanate; a coarsening solution used in the coarsening is prepared from the following raw materials: 150 to 250 mL/L of sulfuric acid, 80 to 150 mL/L of hydrofluoric acid, 40 to 80 g/L of CrO3, and water as a solvent. According to the ceramic silver plating method for the ceramic filter, the ceramic substrate is subjected to effective coarsening and activating treatment after being subjected to oil removal, so that the chemical plating process is smoothly carried out, the plating binding force of a chemical nickel plating layer and the substrate is improved, good preconditions are created for subsequent copper electroplating and silver electroplating, and finally a plating structure with good metallization binding can be obtained.
本发明属于电镀银领域，具体涉及一种陶瓷滤波器用陶瓷镀银方法。该陶瓷滤波器用陶瓷镀银方法包括以下步骤：将陶瓷基底进行除油、粗化、钯活化，然后进行化学镀镍、电镀铜和电镀银；所述陶瓷基底的主要成分为钛酸镁和/或钛酸钙；所述粗化所用粗化液由以下原料组成：硫酸150‑250mL/L，氢氟酸80‑150mL/L，CrO3 40‑80g/L，溶剂为水。本发明的陶瓷滤波器用陶瓷镀银方法，对陶瓷基底除油后进行有效的粗化及活化处理，使化学镀过程顺利进行，提高化学镀镍层与基底的镀层结合力，为后续电镀铜和电镀银创造良好前提条件，最终可获得金属化结合良好的镀层结构。
