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 circuit board electroplating pretreating reagent, relate in particular to a kind of pore wall charge regulating agent for circuit board.
[background technology]
Wiring board will be processed through some before carrying out chemical plating, and carrying out in the circuit board electric plating method is at first need to bore on the good empty wall, make it have electroconductibility by electroless copper after, electroplate again.Rear employing is directly carried out electro-coppering to wiring board, i.e. so-called directly electroplating technology wherein has a kind of employing palladium colloid technique of mode.Carry out drilling operating before the wiring board production, because the bit effect of running up, so that the composite base material hole wall that is comprised of glass and resin produces 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 colloid, so need a kind of charge adjusting agent to address this problem.In addition in the process of processing, be stained with artificially oil stain, be unfavorable for the carrying out of following operation, so also need to add the operation of oil removing, what adopt 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 large 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 pore wall charge regulating agent for circuit board that the oil stain on the wiring board can also be removed simultaneously.
The technical scheme that the present invention addresses the above problem is: a kind of pore wall charge regulating agent for circuit board of the present invention, 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 occurs, 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 cosurfactant, shares with cats product, can strengthen the aperture penetrative quality of solution, can rise to again the ability of wiring board degreasing, than the OP emulsifying agent better washing is arranged; The sodium-chlor of 0.55%-0.1% promotes the cleaning of liquid and plate face spot in order to chloride-ion source to be provided, and remaining composition then is clear water.
The invention has the beneficial effects as follows: can efficient neutralization on the wiring board with negative charge, be beneficial to the absorption of palladium colloid, carry out in order to carry out subsequent technique, can also wipe oil, electroplating process is finished smoothly.
