立山電化工業 List of Products and Services

When you look inside mobile phones and smartphones, you will find ultra-low-profile narrow-pitch connectors that have partial gold plating on their terminals. "Hoop plating" is a plating method suitable for connector components that connect electronic circuits. It realizes advanced technology that applies a "nickel barrier" to prevent solder wicking during assembly. 【Features】 ■ In the partial plating reel-to-reel line, stripe Au plating and spot Au plating are possible. ■ It supports specifications that combine two types of plating, such as partial Sn plating and partial Au plating, and can propose cost reductions by changing specifications from partial Au plating to partial Sn plating. ■ Our unique special drum and inline laser stripping technology enable the formation of a more precise "nickel barrier" through partial plating. ■ In the reel-to-reel line for full plating, base Ni plating followed by Sn plating is possible. ■ Both Au plating and Sn plating lines can accommodate SUS materials. ■ Supports reflow processing for Sn plating. *Some specifications may have restrictions. *For more details, please refer to the PDF document or feel free to contact us.

We are introducing a case study where we reviewed the spot Au plating jig for our customer company, resulting in a reduction of Au usage in Au-plated components and an improvement in the Ni barrier function, thereby solving their issues. 【Challenges faced by the customer】 The existing customer was troubled by the rising procurement costs of Au-plated components for connectors due to the recent surge in Au market prices. Additionally, they were also struggling with unnecessary solder wetting on certain areas during the PCB assembly of the connectors, which led them to consult with us. For details on the solution, its effects, and results, please download the case study from the catalog below or feel free to contact us.

We would like to introduce a case where we reviewed the process design and conducted prototype production for a customer company, successfully reducing the variation in Sn plating. In this company, the customer was developing an automotive connector and required Sn plating on a certain component. However, they were unable to meet the specified range of plating thickness required by the customer, making it difficult to fulfill the connector's functionality. By reviewing our plating process design and developing a dedicated jig, we repeatedly went through trial and error in the prototype production, which allowed us to reduce the variation in plating thickness. Ultimately, we were able to achieve the process capability that the customer was looking for. 【Case Overview】 ■ Background - Sn plating thickness could not meet the specified range, making functionality difficult. ■ Effect - The customer's product development was successfully advanced, allowing for the product to be launched in mass production, thereby gaining the customer's trust. *For more details, please download the PDF or feel free to contact us.

【Challenges faced by the customer in the case study】 ■Au Plating The existing customer was troubled by the rising procurement costs of Au-plated components for connectors due to the recent surge in Au market prices. Additionally, they were also struggling with solder wetting on unnecessary parts during the mounting of connectors on the circuit board, and sought our consultation. ■Sn Plating For a vehicle-mounted connector that the customer was developing, they required Sn plating on a certain component. However, they were unable to meet the specified thickness range for the plating that the customer desired, making it difficult to satisfy the functionality of the connector. *For details on the solutions and effects, please refer to the PDF document or feel free to contact us.
