In short, DC power cord as a key component in the transmission of DC power, its performance and safety is crucial. Through the introduction of this article, I hope to help you better understand and use the DC power cord.

The Application of Eco-Friendly Inorganic Pigments in Solder Mask Ink

In recent years, with the rapid development of the economy and the swift advancement of informatization, digital electronic products are constantly being innovated and updated, leading to a rapid growth in the use of solder mask ink for printed circuit boards. Solder mask ink typically consists of resin, solvent, pigments(KingChroma), and additives. As environmental awareness has increased, the production and application of solder mask ink have also begun to trend towards being eco-friendly and harmless.

Eco-friendly inorganic pigments, due to their non-toxicity, resistance to acid, alkali, chemical corrosion, and good thermal stability, are gradually gaining more attention and application in the field of solder mask ink. The colors of solder mask ink are quite varied, and the commonly used eco-friendly inorganic pigments mainly include:

Green Inorganic Pigments: Currently, most circuit boards on the market are green, so the application of green inorganic pigments in solder mask ink is the most extensive. Green solder mask ink provides better visual effects in yellow light rooms and is easier for optical positioning and correction, friendly to the eyes, beneficial for workers observing circuit boards. When disposed of, they can be recycled at high temperatures without releasing toxic gases. Considering these characteristics, green solder mask ink typically uses cobalt green pigment, which, apart from its stability and weather resistance, also meets environmental and health safety standards such as the RoHS directive for hazardous substance restrictions.

Yellow Inorganic Pigments: Yellow solder masks are primarily used for circuit boards that require flash gold or gold sinking. Such circuit boards need to be first coated with yellow solder mask and then undergo metallization. The yellow solder mask maintains its original color after metallization. Common yellow inorganic pigments used in yellow solder mask ink include titanium nickel yellow, titanium chrome brown, zinc iron yellow, etc.

Red Eco-Friendly Pigments: Red background makes it easier to detect errors and poor soldering points on PCB circuit boards, hence it's commonly used for high-precision, complex, and highly reliable circuit boards. Considering environmental requirements, harmful lead and cadmium elements should not be included. Red solder mask ink is recommended to use composite titanium red pigment, which is eco-friendly, non-toxic, and has outstanding performance.

Additionally, solder mask ink colors also include blue, white, black, etc. The specific ink used depends on customer requirements, design standards, and the desired functionality and performance. Excellent solder mask ink can prevent moisture and various electrolytes from invading, protecting the circuit, offering oxidation resistance, and increasing its insulating properties. As the functions of electronic products continue to expand, the functional requirements for solder mask ink become increasingly diverse. In practical applications, appropriate inorganic pigments with suitable characteristics can be chosen according to the requirements of the solder mask ink, ensuring the product's quality and environmental performance.

With increasing environmental requirements and technological progress, the application of eco-friendly inorganic pigments in solder mask ink will become more widespread. Their excellent performance and environmental advantages not only improve the performance and color options of solder mask ink but also meet modern environmental requirements, reducing negative impacts on the environment and human health.
