We provide precision metal components using materials such as SUS, Al, Ti, and invar. These products are produced through a combination of high-precision photomasks and etching, along with technologies such as precision electroforming. The products are utilized as masks for deposition, encoders, electronic component assembly jigs, precision washers, and so on. In addition to thin standalone metal objects, we also provide products subjected to bending, lamination, black plating, and the like.
Metal Laser Processing
In laser processing, a pattern is formed by irradiating a YAG laser onto a metal plate, melting it, and penetrating it. Since a photomask is not required, it is recommended for creating products in small lots. Line width accuracy is ±10um.
Examples of production by Metal Laser Processing
A pattern of 100 to 500 um is expressed using SUS304 material with a thickness of 0.1 mm. We recommend that the thickness of the metal plate be the same as the minimum line width.
This is an enlarged view of the opening of the laser processed product. The R diameter of the corner part is approximately 12um.
Photo-etching of Metals
Photo-etching technology is a precision processing technology which, without using a metal mold, is capable of producing complex and minutely detailed shapes with high precision, short lead times, and low cost. We support a variety of metals, including stainless steel, as well as Al, Ti, Cu, and invar. These support half-etching processes as well. We also offer high aspect ratio metallic etching products based on our proprietary methods.
Examples of production using Photo-etching of Metals
This is a SUS mask. This product is patterned using metal etching. The thickness of the SUS material is 0.3mm.
This is a gradation type SUS mask with rectangles that gradually increase in size. The thinnest wire part is approximately 14um. We select and set the thickness of SUS according to the line width of the pattern.
This product is made by half-etching SUS material and then applying black paint to the processed areas. Half-etching is used for reflective charts and product numbering.
Nickel Electroforming
Shapes that cannot be produced using photo-etching, finely detailed shapes, and the like can be produced to a high degree of precision using nickel electroforming. With electroforming, shapes result from the transfer of a resist image and thus have extremely high processing accuracy.
Examples of production using Nickel Electroforming
This is a product that expresses the resolution pattern using electroforming.
This is a honeycomb pattern product with a Ni part of 20um and a pitch of 60um.
