Description
Technical field
The utility model relates to a kind of disrupter, is specifically related to a kind of plating tank isolation plating baffle plate, for the flexible partition in electroplate liquid region.
Background technology
In prior art, interconnection structure is to adopt alloy for main raw, specifically can adopt metal level or the film of following method deposit alloy: physical vapor deposition (PVD) method, chemical vapour deposition (CVD) method and electrochemical plating.Wherein, electrochemical plating can easily obtain highly purified metal level or film, and not only the formation speed of metal level or film is fast, but also can control the thickness of metal level or film with comparalive ease, and therefore electrochemical plating become main stream approach.Plating refers in the saline solution containing pre-metallizing, with plated matrix metal for negative electrode, by electrolytic action, the positively charged ion of pre-metallizing in plating solution is deposited in base metal surface, forms a kind of method of surface finish of coating.Coating performance is different from matrix metal, has new feature.Electroplate the difference according to plating, the electroplating technology groove arranged also is not quite similar, but before the electroplating process that general plated item completes an electroplating technology groove enters next electroplating technology groove, all to wash at washing bath, the effect of washing bath is the residual electroplate liquid wash clean above workpiece, do not affect lower one technique to carry out, do not pollute electroplate liquid in lower one plating tank, thus ensure the quality of plating.
Plating needs to carry out at a certain temperature.In general, improve temperature, the electroconductibility of plating solution can be increased, improve the current density that reaction allows, also can improve speed of response and coating uniformity.On the impact of additive also clearly, temperature raises temperature, and current density can raise, and this is favourable to the adsorption potential reaching optical brightener.At present, the type of heating of bath solution generally can divide two kinds: one is direct-fired mode, namely heat exchanger is directly inserted in electroplate liquid, direct heating; A mode for indirect heating, as water jacket method, adjustment channel process.The thermal source of bath solution heating generally comprises: calrod, steam, high-temperature-hot-water etc.
Galvanic anode baffle plate is added in the power line division board between workpiece to be plated (i.e. negative electrode) and plated source metal (i.e. anode) in plating tank.Its effect is that the size by arranging position of opening and hole controls power line homogeneity, guarantees that workpiece to be plated coating is even, under the condition ensureing thickness of coating quality, plated source metal consumption is controlled.Plating tank close to being the position that in electric field, the density of electric fluxline is maximum bottom liquid level position and plating tank, be high current density region, and the plating tank medium position position that to be the density of electric fluxline minimum, electric current is minimum, and current density is minimum, is low current density district.The plated film of the workpiece of high current density region is thicker, sometimes also there will be " burning " long burr phenomena because electric current is large, impact assembling and outward appearance, and the workpiece plated film in low current density district is thinner, impact assembling or product performance.
