Finding a "datasheet" for can be tricky because it isn't actually a single electronic component like a resistor or a chip. Instead, these markings represent the "birth certificate" of the printed circuit board (PCB) itself, indicating who made it and how safely it handles fire. Decoding the Marking If you see
UL Requirement
: If a board is required to be UL-certified , the manufacturer must include their registered logo or code (like SH1) for tracking and warranty purposes.
If you can provide a photo or describe what the device looks like (e.g., "a blue circuit board with a USB port"), I can help you locate the specific datasheet for the component.
Below is the standard content found in a datasheet for a 94V-0 rated PCB. 1. Product Overview Substrate Material : Commonly (Flame Retardant 4), a glass-reinforced epoxy laminate. Flammability Rating
- UL 94: A safety standard for flammability of plastic materials.
- V-0: The highest (best) rating for vertical burning. It means the plastic stops burning within 10 seconds after the flame is removed and does not drip flaming particles.
- Burning stops within 10 seconds after two separate 10-second flame applications.
- No flaming drips that ignite the cotton indicator placed below the sample.
- The specimen does not burn completely.
SH1 94V-0 is a UL (Underwriters Laboratories) rating that signifies a material's compliance with specific flame retardancy standards. The "SH1" refers to a particular set of tests and requirements for materials used in devices and appliances, while "94V-0" denotes the level of flame retardancy achieved by the material.
