3 CRITERIA TO EVALUATE TECHNICAL PLATING LAYERS INTERNATIONAL STANDARDS

For modern industries, technical electroplating is not merely a surface protection layer but also a key quality benchmark that ensures product value and performance. Moreover, controlling alloy composition and chemical safety levels has become increasingly crucial as environmental regulations and international certifications grow more stringent. DC Technologies introduces three international standards for evaluating technical plating quality, helping businesses maintain strict quality control, enhance production efficiency, and ensure compliance with global environmental and safety standards.

I. Introduction

1. What is Electroplating?

Technical electroplating is the process of coating a layer of metal onto a material’s surface to enhance its technical properties such as durability, corrosion resistance, wear resistance, electrical conductivity, or thermal conductivity.

Unlike decorative plating, technical electroplating focuses primarily on the functionality and performance of the product rather than its aesthetic appearance.

2. Benefits of High-Quality Technical Plating Layers

– Superior corrosion resistance: Protects metals from oxidation and rust in harsh environments.

– Enhanced durability and wear resistance: Reduces surface damage from impact or friction, extending the lifespan of mechanical components.

– Improved electrical and thermal conductivity: Ensures optimal performance for electronic components, printed circuits, and conductive devices.

– Maintained dimensional accuracy and uniformity: Smooth, even plating preserves mechanical tolerances, crucial for precision parts.

– Increased product value: Durable, glossy plating combined with enhanced technical performance elevates both the commercial and professional value of the product.

II. 3 Criteria for Evaluating Technical Plating Layers According to International Standards

1. Standard for Thickness and Adhesion of Plating Layers

Optimal thickness: The plating layer should be thick enough to protect the surface from wear and impact, yet not so thick that it causes cracking or peeling.

Strong adhesion: The coating must bond perfectly with the substrate, ensuring it does not delaminate or degrade under mechanical stress or environmental exposure.

2. Standard for Surface Brightness, Uniformity, and Aesthetics

Perfect gloss: The plating layer should maintain a consistent shine, giving the product a premium and visually appealing appearance.

Absolute uniformity: The surface must be free of streaks or spots, ensuring both aesthetic quality and even protective performance.

Visual impact: An attractive plating finish enhances product value and immediately captures customer attention.

3. Standard for Corrosion Resistance and Chemical Durability

Corrosion resistance: The plating layer must protect the substrate from environmental factors such as humidity, salt, chemicals, or industrial emissions.

Chemical durability: It should withstand common chemicals the product may encounter, including mild acids, alkalis, or cleaning solutions, ensuring long service life and reduced maintenance costs.

III. SpectraX 55 – Precision Analysis for Plating Layer Thickness

To meet international standards for plating quality, controlling thickness, alloy composition, and safety levels is essential. SpectraX 55 is an advanced analytical device that enables fast, precise, and efficient monitoring of the plating process.

1. Accurate and Rapid Multi-Layer Thickness Measurement

The SpectraX 55 can measure the thickness of up to five plating layers, ranging from a base layer to complex alloys, without damaging the surface. This allows users to easily analyze a wide variety of metallic coatings on different substrate materials. Notably, it offers a measurement precision of up to 0.001 μm, a technological feature rarely matched by other XRF devices on the market.

2. Alloy Composition Analysis of the Plating Layer

Even more remarkably, the SpectraX 55 can accurately analyze the alloy composition of plating layers, including precious metals such as gold (Au), silver (Ag), palladium (Pd), platinum (Pt), and rhodium (Rh), as well as industrial metals like copper (Cu), nickel (Ni), zinc (Zn), and chromium (Cr). This capability enables businesses to maintain strict quality control, ensure metals are present in the correct proportions, and enhance both the durability and aesthetic appeal of their products.

3. Toxicity Testing in Compliance with RoHS Standards

In addition to measuring plating thickness and analyzing metal composition, the SpectraX 55 also detects hazardous substances such as Pb, Cd, and Cr⁶⁺ in accordance with RoHS, WEEE/ELV, EN71, and TCVN standards. This ensures that products meet international certifications and are safe for end users. Such capabilities are especially critical for industries that require strict environmental compliance and alignment with current global sustainability trends.

4. Smart and Convenient XYZ Movement System

The 3D (XYZ) moving stage of the SpectraX 55 can support a maximum load of 5 kg, providing flexibility for measuring larger samples, saving time, and optimizing operational workflow. Its high-resolution camera assists in precise measurement positioning, further enhancing the accuracy of the analytical process.

5. Wide Applications Across Various Industries

5.1 Electronics and PCB Components

In the mechanical components, automotive, and household appliance industries, the SpectraX 55 assists in measuring plating thickness on mechanical products, ensuring coatings meet strict technical requirements before production. The device helps businesses optimize quality, reduce errors, and enhance operational efficiency.

5.2 Jewelry Industry

The SpectraX 55 is highly valuable in the jewelry sector, as it can measure the thickness of gold, silver, rhodium, and platinum plating on jewelry items, while also analyzing the alloy composition of the plating. This ensures both the quality and aesthetic appeal of the products, delivering perfect finishes and maximizing commercial value.

5.3 Hazardous Substance Testing in Components and Consumer Goods

With the capability to test for hazardous substances according to standards such as RoHS/WEEE/ELV, EN71, and TCVN, the SpectraX 55 enables companies in the electronics, jewelry, and consumer goods industries to ensure their products are safe for end users, particularly children. This not only enhances brand reputation but also ensures compliance with environmental regulations.
