Abstract
The invention relates to a novel method for preprocessing an electrotinned glue-filled product. The method comprises the following steps: polishing a product needed to be filled with glue, polishing, washing by water for three times, and activating by sulfuric acid to obtain the electrotinned glue-filled product. According to the method, the preprocessing operation is carried out in a low-temperature environment, so that the luster and the flatness of the appearance of the glue surface and a copper material of the electrotinned glue-filled product are effectively protected.
Description
Technical field
The novel method that the present invention relates to the pre-treatment of a kind of eleetrotinplate encapsulating product, belongs to chemical field.
Background technology
The hot polishing of former process using of eleetrotinplate encapsulating product pre-treatment is carried out pre-treatment to product, processing temperature 30-40 degree, when operation, at high temperature in polishing fluid, contain a large amount of sulfuric acid, sulfuric acid is strong oxidizer, at high temperature there is violent corrosion with encapsulating glue face, simultaneously to copper material also strong corrosion, make the smooth glue face of otherwise smooth matt and coarse, this phenomenon is easily turned white when Passivation Treatment (hydroxide ion) when passivation in follow-up eleetrotinplate.
Summary of the invention
Technical problem to be solved by this invention is to provide the novel method of a kind of eleetrotinplate encapsulating product pre-treatment, and the inventive method adopts pre-treatment operation under low temperature environment, has effectively protected the gloss, smooth of eleetrotinplate encapsulating product glue face and copper material outward appearance.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: the novel method of a kind of eleetrotinplate encapsulating product pre-treatment, comprising:
Get the product that needs encapsulating, polishing, three road washings, activation, to obtain final product.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described polishing fluid is by chromic acid: technical grade sulfuric acid: water by volume 1:2:28 forms, burnishing parameters M type condensation pipe control polishing fluid temperature 10-20 degree, polishing 10-20s.
Further, described three road washings refer to three road overflow waters, in first pond, discharge water, and allow it overflow to successively second and third road, and when washing, Cong tri-roads start to wash first successively.
The beneficial effect that adopts this step is both water saving, also can be material wash clean.
Further, described activation adopts the mixture of technical grade sulfuric acid and water, and counting by volume the volume ratio that technical grade sulfuric acid accounts for water is 1-3%, the product after washing is immersed in solution completely after taking-up immediately.
The invention has the beneficial effects as follows:
The inventive method adopts pre-treatment operation under low temperature environment; the oxidisability of sulfuric acid reduces immediately at low temperatures; main aobvious acid; be responsible for removing product copper copper oxide surface and glue face oil mark; when polishing reaction temperature and, effectively protected glossiness, the planarization of eleetrotinplate encapsulating product glue face and copper material outward appearance.
