In chip R&D and mass production, testing plays a vital role in ensuring product quality and timely delivery. One semiconductor packaging and testing company faced unstable testing results and high contact resistance, affecting production efficiency and yield. After analyzing the challenges, Yiding Technology quickly formed a dedicated engineering team to design a customized solution featuring high-precision test sockets and highly conductive test wafers. By optimizing pin structures and surface plating processes, the new design significantly improved signal stability and product durability. As a result, the client’s test yield increased by about 8%, stability improved by 25%, and maintenance costs were reduced. The client highly recognized Yiding Technology’s rapid response, product quality, and technical expertise, establishing a long-term partnership. Yiding Technology remains committed to innovation and professionalism, delivering reliable and efficient one-stop semiconductor testing solutions to customers worldwide.

1. Project Overview This case study comes from one of our long-term automotive clients in the United States, specializing in high-end car phone mounts and aluminum fire extinguisher brackets. All of the products are visible exterior parts, which means the customer’s primary focus was on aesthetic quality, flawless finishing, and consistent assembly. The client needed a complete OEM solution — from precision machining to surface finishing, assembly, and packaging — a true one-stop service. They required multiple elegant surface finishes such as anodizing, polishing, powder coating, and laser engraving, each suited for different product lines. 2. Part Details Specification Description Product Types Car fire extinguisher brackets, various models of aluminum phone mounts Material Aluminum 6061, Medium Carbon Steel Machining Methods CNC turning-milling, CNC machining center, laser cutting, bending, riveting Precision ±0.01mm Surface Treatments Anodizing, Polishing, Powder Coating, Laser Engraving Keywords CNC precision machining, anodized aluminum parts, automotive accessories, OEM manufacturing, one-stop assembly service 3. Challenges & Process At the start of the project, the main challenges were: Complex appearance requirements – The customer wanted a satin-polished finish with smooth, consistent reflection. Surface finishing difficulties – Combining different materials and finishes (aluminum anodizing and steel powder coating) required precise process control. Packaging and transportation – Since the products were for export and easily scratched, long-distance shipment protection was a major concern. 4. Results & Client Feedback The final parts exceeded the client’s expectations: Precision tolerance controlled within ±0.01mm Perfect satin-polished and anodized surface, free from scratches or blemishes Strong, clean assembly structure suitable for both aluminum and steel components 100% on-time delivery for every batch The client appreciated our patience, technical expertise, and problem-solving attitude throughout the sampling stage — even though prototyping was time-consuming and costly, we remained committed to building a long-term partnership. As a result, they decided to entrust all of their automotive accessory production to us, with continuous reorders and referrals to their business partners. 5. Summary This project demonstrates our ability to provide end-to-end OEM manufacturing solutions — from CNC machining and surface treatment to assembly and packaging — with consistent quality and precision. Whether it’s high-end aluminum phone holders or durable automotive brackets, our team ensures that every product delivered is both mechanically accurate and visually stunning.

1. Customer Background Our client is an automotive manufacturer from the United States, specializing in high-end motorcycle and car components. They required a series of parts with exceptionally high surface quality and precision, featuring multiple surface treatment options, such as: Polishing + purple anodizing with a uniform glossy finish Polishing + bright chrome plating with a mirror-like reflective surface Absolutely no scratches or surface defects allowed The customer provided Pantone color samples to ensure color accuracy and consistency across all anodized parts. Item Description Part Name Motorcycle control lever and related components Material Aluminum 6061, Stainless Steel 304 Machining Process CNC turning & milling, 5-axis machining, CNC machining center Precision Requirement ±0.01mm Surface Treatment Polishing, Anodizing, Chrome Plating Keywords CNC precision machining, anodized aluminum parts, automotive components, mirror surface finishing 3. Machining Process & Technical Challenges During production, we faced several challenges: Multi-process surface finishing compatibility — Combining polishing with anodizing or chrome plating risked color inconsistency and uneven reflection. High-gloss surfaces easily scratched — Handling, clamping, and inspection could cause micro-scratches if not properly protected. Tight dimensional tolerance — The control lever’s critical assembly areas required ±0.01mm accuracy.
