In the world of printed circuit board (PCB) manufacturing, coverlams play a crucial role as a "protective outer layer." Halogen-free yellow coverlams are key materials designed to meet environmental, safety, and high-performance requirements. Combining protection, insulation, marking, and eco-friendly safety, they are indispensable in modern electronic products, particularly in consumer electronics and demanding applications. Halogen-free yellow coverlams serve as a protective film on circuit boards, with the following primary functions:
1. Protection circuit:
It is like a sturdy "coat" that covers precise circuits, preventing scratches, wear, and corrosion from humid air, ensuring that the circuit will not short circuit and can work stably for a long time.
2. Environmental protection and safety:
'Zero halogen' is its core characteristic. It does not use flame retardants containing halogens such as bromine and chlorine. This is more environmentally friendly after disposal, and in case of a fire, it will not release toxic smoke during combustion, making it safer.
3. Easy to inspect and produce:
The yellow background creates a sharp color contrast with the solder joints, circuits, and components on the circuit board. This enables workers or inspection machines to see more clearly during production and maintenance, making it easier to detect defects and improve production efficiency and quality.
4. Identification and Aesthetics:
Among numerous circuit boards, yellow has also become a common identifier, sometimes used to distinguish products of different models or functions, and to make the appearance of the product more professional and beautiful.
In summary, the halogen-free yellow coating combines protection, safety, ease of use, and environmental friendliness, making it an important and thoughtful design in modern electronic products.
