OSP Halogen-Free Flame Retardant 4-Layer Board PCB
This is a specialized four-layer printed circuit board (PCB) that uses an Organic Solderability Preservative (OSP) surface finish and is made from halogen-free flame retardant materials. This combination of features makes the board environmentally friendly, safe, and reliable for a variety of electronic applications, particularly where environmental regulations and safety standards are a priority.
Product Characteristics
•Halogen-Free Material: Unlike traditional PCBs that use halogenated flame retardants (like bromine), this board uses a non-halogenated alternative. This is a key feature for environmental and health reasons, as halogens can release toxic fumes when burned or incinerated.
•4-Layer Stack-up: The four layers allow for more complex circuit designs and better signal integrity than a two-layer board. The additional inner layers can be used for dedicated power and ground planes, which helps to reduce electromagnetic interference (EMI) and improve electrical performance.
•OSP Surface Finish: The OSP finish is a thin, organic coating that protects the exposed copper from oxidation until the soldering process. It is a very environmentally friendly and cost-effective alternative to other finishes like HASL or ENIG. It provides a flat, uniform surface, which is ideal for fine pitch components.
•Flame Retardant: The material is designed to prevent the spread of fire. In the event of a short circuit or other failure that could cause a fire, the board material will self-extinguish.
Main Application Scenarios
•Consumer Electronics: Devices like laptops, mobile phones, and tablets where environmental standards and safety are important factors.
•Networking and Communication Equipment: Routers, switches, and servers, which require high-performance, multi-layered PCBs that meet industry safety standards.
•Medical Devices: Equipment that needs to be both highly reliable and compliant with strict safety regulations.
•LED Lighting: Used in LED drivers and control boards where heat and fire safety are crucial concerns.
