The present invention relates to a matrix for electrotype screen grids, the electroformed system for electrotype screen grids, the method electrotype screen grid, and screen grid, obtained by electrotype and includes fastening elements at its edges for entry into mechanical engagement with the mounting frame.

Stencil, which is often called the stencils used in the production of printed circuit boards when applied by a printing substance, usually are either solder paste or other adhesive substance on the printed circuit Board.

Electroplating is widely used for the production of screen meshes, and these stencil described, for example, in documents

US-A-5359928 and US-A-5478699.

Now with reference to Fig. 1-6 will be described electrotype these screen grids.

The electroformed system contains 3 bath containing the electrolyte solution 5, node 7 matrix, which is in the bath 3 and to which is applied a metal electro-deposition for forming a stencil, node 9 of the anode, which is located in the bath 3 and provides a source of ions of the deposited metal, and the node 11 of the power source which is electrically connected to node 7 matrix and uz is ω 9 of the anode and works exciting electric current passing through the electrolyte solution 5, while the minus node 11 of the power source is connected to node 7 matrix, and plus node 11 of the power source is connected to node 9 of the anode.

A solution of 5 electrolyte, typically an aqueous solution that contains a dissolved salt of the deposited metal, usually Nickel, and leveling additives, which regulate the hardness of the deposited metal.

Node 7 matrix contains a matrix 15, on which is applied by electrotype screen grid and the supporting element 17, as a rule, support rod, to give support matrix 15 in the tub 3 and provide electrical connection with it.

Figure 2 shows a partial section through the matrix 15.

Matrix 15 has a flat metal plate 19 is generally rectangular in shape, which includes first and second oppositely directed flat main surfaces 21, 25, with one main surface 21 is surface deposition, which precipitated metal for forming a stencil that will be described in more detail below.

Matrix 15 further comprises a non-conductive element 26, covering the surface and made of a resist, on the other main surface 25, which serves to prevent deposition of metal on said surface.

Node 9 of the anode contains an anode plate 31 generally the same rectangular shape as the matrix 15, and is made of metal, deposited as a stencil, and the support element 33, as a rule, a support rod for supporting the anode plate 31 in the tub 3 and provide electrical connection with it.

This current causes the displacement of metal ions from the anode plate 31 to the open areas of the surface 21 of the deposition plate 19 matrix of open areas which metal ions are deposited as metal, which allows to increase the screen grid by continuous deposition of metal on the surface 21 of the deposition plate 19 of the matrix.

This process is allowed to persist until, while on the surface 21 of the deposition plate 19 of the matrix will not be increasing layer thickness, which is screen mesh S, as shown in Fig. 4, and at this point turn off the node 11 of the power source and remove the node 7 matrix of the bath 3.

After that remove the non-conductive elements 27A, 27b, 29 on the surface 21 of the deposition plate 19 of the matrix, removing the resist and leaving the screen grid S, as shown in Fig. 5.

Then screen mesh S is separated from the die 15, as shown in Fig. 6, lifting the edge, released by removing framing element 29, and after cleaning the grid is ready to use.

In Fig. 23-28 shows partial views of the node 107 matrix as another modification of the above-described first variant implementation.

Node 107 matrix in this embodiment is very similar to that described in the first embodiment, and differs only in the configuration of edge and corner sections 127a-d, 129a-d plate 119 of the matrix.

In this embodiment, each of the boundary sections 127a-d contains a first concave surface 163, in this case arc, which runs outward and backward from the corresponding edge surface 121 deposition and comes back inside and back to the place, separated back inside and away from the respective edge surface 121 of the deposition, the second inclined surface 165, which takes place inside and back from the rear of the far end of the concave surface 163, and a third, depth, surface 167, which takes place from the inner end of the inclined surface 165 to the other bases of the second surface 125 in the direction essentially perpendicular to the surface 121 of the deposition. As will be described in more detail below, the main areas of concave surfaces 163 remain open for the reception of sludge metal, which leads to the formation taking place in the inward hook fasteners E, stencil S, obtained by electrotype.

In this embodiment, a non-conductive boundary elements 143a-d from the first to the fourth protects the region of the far end of the concave surface 163, and inclined and in-depth surfaces 165, 167 of the corresponding one of the boundary areas a-d, leaving the main areas of concave surfaces 163 regional areas a-d open for the reception of sludge metal.

In this embodiment, non-conductive corner elements a-d protects the corresponding one of the corner sections a-d so that the sediment can only be made on essentially straight edge sections a-d.

In this embodiment, the concave surface 165, and in that the fastening elements e of the stencil S, have a transverse ledgepof approximately 0.5 mm in a plane parallel to the surface 121 of the deposition. Due to the relatively small extent of the transverse ledgepand going back and the inside of the arcuate continuation of the concave surface 163, and thus is it and fasteners E stencil S, elasticity, albeit limited, stencil S provides exemption stencil S from the plate 119 of the matrix.

During the works include the node 111 power source to energize the electric current through a solution of 105 electrolyte between node 107 matrix and node 109 of the anode. This current causes the displacement of metal ions from the anode plate 151 to the open surfaces of the plate 119 of the matrix, and these open surfaces, i.e. the open areas of the surface 121 of the deposition and the open areas of the concave surface 163 regional areas a-d, metal ions are deposited as metal, which allows to increase the screen grid S by continuous deposition on the plate 119 of the matrix.

This process is allowed to persist as long as the matrix 115 will not increase the layer thickness, which is screen mesh S, as shown in Fig. 27 and 28, and at this point turn off the node 111 of the power supply and remove the node 107 matrix of the bath 103. In Fig. 27 and 28 depict screen mesh S in accordance with the second embodiment of the present invention, which includes fastening elements at its respective edges.

After that remove the non-conductive elements 141, 143a-d, a-d, 147, in this embodiment, removing the resist and the OST is opened screen grid S.

Then screen mesh S is separated from the matrix 115, and after cleaning the grid is ready to use.

In this embodiment, the supporting elements 250a-d are annular supports, which are formed of non-conductive annular members, which in this case is made of epoxy resin and placed in the annular channel cut into the plate 219 of the matrix.

Node 209 of the anode contains an anode plate 251, in this embodiment, the same rectangular shape as the matrix 215, and is made of metal, deposited in the form of the stencil S, and the reference element 253, in this embodiment, support arm for maintaining the anode plate 251 in the tub 203 and provide electrical connection with it.
