Abstract
The invention discloses a pore wall charge regulating agent for a circuit board. The regulating agent consists of the following components in percentage by weight: 8.5 to 14.5 percent of triethanolamine, 0.6 to 9.5 percent of hexadecyl ammoniumchloride, 0.3 to 0.6 percent of NP-9, 0.55 to 0.1 percent of sodium chloride, and the balance of fresh water. The regulating agent can effectively neutralize negative charge carried on the circuit board, is favorable for adsorption of a palladium colloid to facilitate the subsequent process, and can remove oil stains to ensure that the electroplating process can be completed smoothly.
Description
[technical field]
The present invention relates to the agent of wiring board pre-electroplating treatment, relate in particular to a kind of wiring board hole wall electric charge and adjust agent.
[background technology]
Wiring board will be handled through some before carrying out chemical plating, and carrying out electric plating method in the circuit board is at first need bore on the good empty wall, make it have electroconductibility by electroless copper after, electroplate again.The back is adopted and directly wiring board to be carried out electro-coppering, and promptly so-called directly electroplating technology wherein has a kind of employing palladium colloid technology of mode.Carry out drilling operating before the wiring board production, because the bit effect of running up, make the composite base material hole wall of forming by glass and resin produce static, this static is the negativity electric charge, because the used palladium colloid catalyst of chemical-copper-plating process also is negativity, do not utilize the absorption of palladium colloidal, so need a kind of charge adjusting agent to address this problem.In addition in the process of processing, be stained with oil stain artificially, be unfavorable for the carrying out of following operation, so also need to add the operation of oil removing, what adopted in traditional technology is alkaline degreasing, and its main effective constituent is mineral alkali, sodium hydroxide, potassium hydroxide and OP-10.And technological operation this moment temperature is very high, generally needs 40 °-50 ℃, and the temperature that needs for this product is higher, needs stable operation to reach 60-70 ℃.
[summary of the invention]
The present invention provides a kind of oil removing and adjustment electric charge two big functions of integrating for addressing the above problem, in and substrate on the negative electrostatic lotus, make it the lotus that becomes positively charged, so that the palladium colloid of absorption negative charge, a kind of wiring board hole wall electric charge that the oil stain on the wiring board can also be removed is adjusted agent simultaneously.
The technical scheme that the present invention addresses the above problem is: a kind of wiring board hole wall electric charge of the present invention is adjusted agent, and its composition is by weight: the trolamine of 8.5%-14.5%, purpose are to provide the alkali environment and as the solvent of cetyl chloride ammonium; The cetyl chloride ammonium of 0.6%-9.5%, a kind of cats product can be dissolved in the trolamine, and the ammonium ion that ionization reaction ionization produces positively charged takes place, and the ammonium ion of described positively charged is as the cation source of adjusting agent; The NP-9 of 0.3-0.6%, its effect is a cosurfactant, and is shared with cats product, can strengthen the aperture penetrative quality of solution, can rise to the ability of wiring board degreasing again, than the OP emulsifying agent better water washing arranged; The sodium-chlor of 0.55%-0.1% promotes the cleaning of soup and plate face spot in order to chloride-ion source to be provided, and remaining composition then is a clear water.
The invention has the beneficial effects as follows: in can be effectively and on the wiring board with negative charge, be beneficial to the absorption of palladium colloid carry out so that carry out subsequent technique, can also remove greasy dirt, electroplating process is finished smoothly.
