Electrolytic polishing of copper

Electrolytic polishing of copper

"Electropolishing" to improve the surface roughness of copper and enhance its gloss.

**Features of Copper Electrolytic Polishing** ◆ Enhances Gloss It brings out the beautiful gloss of copper. It achieves a high gloss level that cannot be obtained through chemical polishing. ◆ Achieves Clean and Smooth Surfaces It results in surfaces with low roughness. Furthermore, it provides a clean surface property without any processed altered layers or foreign substances. Generally, the surface roughness obtained is finer than that achieved through chemical polishing. ◆ Polishing of Areas Impossible with Physical Polishing There are areas that cannot be polished due to the size of the polishing tools in physical polishing. Electrolytic polishing allows for the polishing of such fine areas. ◆ Vacuum Packaging Available Upon Request Copper oxidizes due to oxygen in the air. To prevent oxidation, it is possible to vacuum package the product after electrolytic polishing before shipping. ◇◇ Please feel free to contact us for more details ◇◇

Back surface polishing of semiconductors for luminescence analysis.

Back surface polishing of semiconductors for luminescence analysis.

Back grinding is possible with various types of semiconductors! You can observe the elements and the condition of defects.

Back Surface OBIRCH / As a preprocessing step for luminescence analysis or back surface luminescence analysis, we perform back surface polishing of samples with various shapes. This is an essential preprocessing step for conducting analysis from the back surface. By analyzing from the back surface, it is possible not only to detect luminescence while retaining defects but also to observe the presence or absence of shape abnormalities. Additionally, back surface polishing can be performed on various forms of semiconductors, such as packages, opened chips, and wafers, and it is also possible to perform back surface polishing while preserving the lead terminals. 【Features】 ■ Back surface analysis requires polishing because it does not transmit light due to shading by electrodes or light attenuation from high-density substrates. ■ Luminescence can be detected while retaining defects. ■ The presence or absence of shape abnormalities can also be observed. ■ Back surface polishing can be performed while preserving the lead terminals. *For more details, please refer to the PDF document or feel free to contact us.

±0.05mm (range of 0.1mm) approximately [R machining and chamfering]

±0.05mm (range of 0.1mm) approximately [R machining and chamfering]

Products processed based on specified values are inspected and managed with our inspection equipment! Introduction to R-cutting and chamfering processing.

Nishimura Giken Co., Ltd. conducts polishing processes such as "R attachment and chamfering." The specified R value is approximately ±0.05mm (with a range of 0.1mm). If the desired processing accuracy can be measured numerically, it is possible to process at the designed target value, and products processed based on the specified values provided will be inspected and managed using our inspection equipment. Additionally, the tolerance is approximately ±0.1. For general processing, we can accommodate the above tolerances. We will make every effort to respond to requested tolerances as much as possible after detailed discussions. 【Features】 ■ R value specification: approximately ±0.05mm (with a range of 0.1mm) ■ Tolerance: approximately ±0.1 ■ If the desired processing accuracy can be measured numerically, processing at the designed target value is possible. *For more details, please refer to the PDF document or feel free to contact us.

Surface finish after barrel polishing

Surface finish after barrel polishing

Advanced inspection equipment and abundant processing facilities that support productivity and technological capabilities! Introduction to glossiness and surface color.

Barrel polishing is a very suitable polishing technique for rounding the edges of machine parts and metal components. It is evaluated based on three factors: surface roughness, glossiness, and surface color, with customer requests such as "finer," "shinier," and "whiter." While surface roughness and corner radius are indicated in the drawings, requests regarding glossiness and color are mostly expressed in abstract terms. The shape of the surface irregularities, or surface characteristics, varies depending on the processing conditions and polishing materials used in our company. Since we do not have color difference meters or gloss meters, the evaluation is based on visual inspection rather than numerical assessment. However, we strive to respond to requests as much as possible by clarifying differences in surface conditions using magnified images from a microscope. *For more details, please refer to the PDF document or feel free to contact us.*

Removal of black discoloration layer [barrel polishing]

Removal of black discoloration layer [barrel polishing]

Solving problems through oil removal (degreasing) and optimization of processing conditions! Introduction of a case study on barrel polishing.

This is a case study on the removal of black discoloration layers. We received an inquiry from another barrel polishing company stating, "We had barrel polishing done, and while the burrs were removed, the surface of the item was delivered discolored black compared to before the polishing. We cannot deliver it to our customer in this condition, so is there any way to restore the material's color?" We performed barrel polishing at our company, removing the black discoloration layer and returning it to the original material color. Depending on the type and amount of oil on the raw material before barrel polishing, as well as the polishing conditions, dirt can sometimes adhere to the surface. This issue can be resolved through oil removal (degreasing) and optimization of processing conditions. *For more details, please refer to the PDF document or feel free to contact us.
