The invention discloses an acid hole conditioning agent used for a hole metallization process of a PCB (printed circuit board) and a preparation method of the PCB. The hole conditioning agent comprises the following ingredients: acid, a hyperbranched polymer taking polyamine as an initiator, a wetting agent and deionized water. Compared with an alkaline hole conditioning agent used in the prior art, in the acid hole conditioning agent, organic carboxylic acid cleaned very easily is taken as a cleaning additive, and the hyperbranched polymer with strong cation characteristic in an acid condition is taken as a surface charge modifier of a dielectric material and is cleaned very easily, therefore, the problems that the quality of hole metallization of the PCB is abnormal due to excessive adsorption of a palladium activator as the alkaline hole conditioning agent is not cleaned easily to cause too much residue of the surface charge modifier, and the like can be improved. The acid hole conditioning agent disclosed by the invention is good in treatment effect and high in efficiency and is suitable for application in the hole metallization process of horizontal continuous operation of thePCB.

The invention provides a baicalin-aluminum dry suspension for treating pigling diarrhoea. Baicalin as an active component is extracted from radix scutellariae and is processed to form an aluminum salt, and the aluminum salt and reasonable auxiliary materials are mixed to form a veterinary pharmaceutical preparation. The baicalin-aluminum dry suspension comprises, by weight, 200-500 parts of an aluminum salt active component containing 50% of baicalin-aluminum, 2-10 parts of a suspending aid, 20-100 parts of a corrigent, and 390-750 parts of a filler. The baicalin-aluminum dry suspension is suitable for pigling before and after weaning, has remarkable effects, can replace the same kind of antibiotics, prevents resistance to drugs, prevents toxic or side effects caused by antibiotics and antibiotic residues and is beneficial to animal and human health.
