By achieving "no use of sulfur-based additives," which was not possible with conventional low-phosphorus electroless Ni-P plating, it has become possible to maintain the long-term wettability of solder, which has been a bottleneck until now. Due to its excellent uniformity in film thickness, plating can be performed without variation even on shapes such as heat sink fins. 【Features】 - The phosphorus (P) content of the Ni coating is low at 2-4 wt%, resulting in minimal "nickel consumption" during solder joining, enabling highly reliable solder joints. - Since sulfur-based additives are not used, it can maintain long-term wettability of solder, and the resulting plating film has excellent discoloration resistance and acid resistance. - A high hardness coating of Hv680 can be obtained without post-plating heat treatment, providing excellent wear resistance. *For more details, please refer to the PDF document or feel free to contact us.

Epitech Co., Ltd. has been responding to various surface treatment needs since its establishment, continuously pursuing technological and production innovations. Many needs, such as wanting to harden the surface of products, enhance conductivity, or reduce friction coefficients, can be achieved relatively cost-effectively through surface treatment technologies primarily based on plating. At Epitech Co., Ltd., we provide high-quality surface treatment as the final process of products with short delivery times. For plating and surface treatment, please consult us for prototypes, single items, or mass production. 【Product Line】 ○ Electroplating ○ Electroless plating ○ Electrolytic polishing and chemical polishing ○ Chemical treatment and others For more details, please contact us or download our catalog.

"Environmentally Friendly High-Precision Electroless Ni-P Plating" is a functional plating suitable for parts that require particularly high-precision film thickness management. Using a chemical reduction method without an external power source, it can uniformly apply a corrosion-resistant plating to products with complex shapes. The amorphous Ni-P alloy coating demonstrates excellent corrosion resistance without the use of a base plating. 【Features】 ■ Uniform deposition ■ High corrosion resistance ■ Wear resistance ■ Non-magnetic ■ Excellent environmental characteristics without the use of harmful substances such as lead and hexavalent chromium *For more details, please refer to the PDF document or feel free to contact us.

"Electroless gold plating" is an electroless process, allowing for a uniform coating on parts with complex shapes. The purity of the deposited film is 99.9%, resulting in a coating that is almost pure gold, with excellent heat resistance and solderability. Additionally, because it is an electroless process, a uniform coating can be achieved on parts with complex shapes. Furthermore, our company accepts orders starting from a single small part, with short lead times and low costs. [Features] ■ Excellent uniform coating on parts with complex shapes ■ High purity gold coating ■ Superior uniformity of the coating ■ Short lead times and low costs for single items and prototypes *For more details, please refer to the PDF document or feel free to contact us.
