Abstract

The utility model discloses an adjustable anode and is characterized in that a movable component is utilized to be connected with a filter bag with an internally-arranged anode titanium mesh or be directly connected with an anode titanium mesh, and the movable component is connected with a driving device, which can drive the movable component to ascend or descend, so as to drive the filter bag or the anode titanium mesh to ascend or descend. In the design of the anode with the filter bag, the movable component can gradually drive the filter bag to descend along with the increase of the electroplating time, so as to control the length of the anode exposed out of the filter bag, enable an anode black film and impurities to be deposited at the bottom of the filter bag, and effectively increase the electroplating quality; and in the design that the anode titanium mesh can directly ascend and descend, the movable component can drive the anode titanium mesh to ascend and descend, so as to enable the height of an electroplated object at a cathode within the range of the anode which is not covered by the black membrane, that is, the part of the anode which is not covered by sludge is matched with the length of the electroplated object. The adjustable anode can enable power lines to be uniformly distributed on a board surface, thereby improving the electroplating uniformity and increasing the electroplating effect.

Description

A kind of anode of adjustable

Technical field

The utility model relates to a kind of electroplating device, relates in particular to a kind of anode of adjustable.

Background technology

Printed circuit board (PCB) must be done copper plating treatment in manufacturing processed, traditionally for the electroplating processes mode of printed circuit board (PCB), be that circuit card is carried by plating tank, and it is following and electronegative to make circuit card be positioned at the electroplate liquid liquid level; In electroplate liquid, also be provided with anode assembly; When printed circuit board (PCB) is transferred, obtain the electroplate liquid of positively charged metal ion in electroplate liquid, the metal ion of positively charged is attached on the electronegative printed circuit board (PCB) and reaches plating action from anode assembly.

Described anode assembly can adopt any suitable material, and wherein, the titanium anode is to be the goods of its reactive material with metal oxide containing precious metals, has been widely used in the field that electroplating industry etc. is converted into electric energy chemical energy at present.General applied lily gilding titanium electrode, its platinum particle is to be deposited on the electrode surface with superfine little state and to be spongy, it has very big surface-area and can contact with electroplate liquid, its surface-area is hundreds of times of level and smooth platinum geometric area, so can lower polarized action, have lower oxygen overvoltage, during as anode to the oxidation capacity of electroplate liquid a little less than, so can slow down the aging speed of electroplate liquid, be existing most popular insoluble anode material.In addition, if in anode titanium net, insert copper ball, then can be used for copper facing; Insert the tin ball, can be used for zinc-plated; Insert the tinsel ball, then be used for zinc-plated lead.

Using the device of titanium metal as galvanic anode at present, is with anode titanium net and the fixed position of all being located at by electronplate in the plating tank, and at the outside sheathed filter bag of anode titanium net; Along with the growth of electroplating time, black film and impurity that anode titanium net produces can fall into filter bag, to avoid sneaking into electroplate liquid; But black film in filter bag and impurity are accumulated more and more for a long time, and its cumulative height can be overlapping with the minimum altitude of circuit card, so that can be subjected to black film and impurity effect at the electroplate liquid of this altitude range, and then reduce electroplating efficiency and quality.

The utility model content

The purpose of this utility model is to provide a kind of anode of adjustable, solving in the prior art meeting and when being accumulate to certain altitude of the black film in the filter bag and impurity, thereby can cause dysgenic problem to electroplating efficiency and electroplating quality by the overlapping of the height of electronplate.

The anode of adjustable described in the utility model includes:

One movable component is connected in a drive unit, and this drive unit can drive described movable component up or move down;

At least one filter bag, its upper end has an opening, and this filter bag is fixed in described movable component, and can rise or descend with this movable component;

At least one anode places in this filter bag non-contactly, and is fixed in the desired height position of a plating tank.

The anode of adjustable described in the utility model includes:

One movable component is connected in a drive unit, and this drive unit can drive described movable component up or move down;

At least one anode is fixed in this movable component, and can change its height with the rising or the decline of this movable component.

The anode of adjustable described in the utility model provides a kind of anode filter bag that can adjust height, it can be by artificial or method for automatically programing, adjust the falling head of filter bag along with the growth of electroplating time, make to fall within the filter bag cumulative anode black film or the impurity height is no more than by the minimum altitude of electronplate, and then avoid influencing electroplating quality and efficient.

The anode of adjustable described in the utility model provides a kind of anode titanium net that can adjust height, decline by control anode titanium net, make negative electrode by the height of electronplate, be positioned at the scope that anode is not covered by black film, even the also part that do not covered by mud of anode and is coincide by electronplate length, power line is evenly distributed in the plate face, promote electroplating evenness, increase electroplating effect.

In the anode of adjustable described in the utility model, filter bag is fixed in a movable component, and this movable component is connected in a drive unit, this drive unit can drive this movable component and rise or descend; Fixed position at plating tank is provided with anode, and this anode is placed in the described filter bag; By controlling this drive unit, be able to along with the growth of electroplating time allow gradually movable component drive filter bag and descend, and then control the length that anode exposes filter bag, make anode black film and impurity be deposited on the filter bag bottom, with effective enhancement electroplating quality.

In the anode of adjustable described in the utility model, anode titanium net is directly fixed on a movable component, and this movable component is connected in a drive unit, this drive unit can drive this movable component and rise or descend, and the anode titanium is online to be risen or descend thereby make.Because anode slime increases with electroplating time, is deposited on anode titanium sieve bottom gradually, electroplating time increases, and then mud height is high more.Negative electrode by the situation of electronplate altitude hold under, the anode slime height with partly overlapped by electronplate length, cause electroplating effect bad.Therefore, look anode slime and pile up situation, the anode titanium that progressively descends net height degree, the part that anode is not covered by mud and is coincide by electronplate length.Power line is evenly distributed in the plate face, promotes electroplating evenness, increase electroplating effect.

Described drive unit can be the operating device of automatization, allows the operator can set up the time of its rising or decline on their own; This drive unit can be a kind of mechanism of manual control also, and the experience that allows the operator comply with self judges that controlling described movable component rises or descend.
