This comprehensive guide explains exactly what these markings mean, how to decipher the safety standards behind them, and how to find the technical information you actually need. 1. Deconstructing the "SH1 94V-0" Marking
The exact same "SH1 94V-0" stamp can appear simultaneously on a microwave control panel, a TV power board, and a computer mouse if those three distinct brands bought their raw PCBs from the same laminating factory. 4. How to Find the Real Data You Need
You will see this printed on the green or blue solder mask of almost every modern PCB to certify it meets international fire safety standards. element14 Community 2. Identifying the "SH1" Marking
< 50 seconds for a set of 5 specimens. Flaming Drips: Absolutely none allowed. sh1 94v-0 datasheet
Because these markings are often etched or silk-screened together, they represent the board's origin and its safety credentials. :
In many instances, "SH" corresponds to manufacturers like Shenghong Electronics , Shengyi Technology , or other major Asian laminate suppliers, with "1" indicating a specific factory production line or base material formulation (such as standard FR-4). Typical Specifications Found in an SH1 94V-0 Datasheet

refers to the board's physical construction rather than its electrical function, you won't find one master datasheet. Instead, engineers look for two separate types of documentation: The UL File (Safety Specs): Often accompanied by an "E" number (like
The board cannot drip flaming particles that could ignite surrounding components.
Perhaps the most common use of "SH1" is as a series code for various —including wire-to-board, board-to-board, and rectangular types—all utilizing UL94V-0 materials for the housing. or other major Asian laminate suppliers
Standardizing on 94V-0 is critical for high-risk or mission-critical applications:
When a board features the 94V-0 stamp, it has passed rigorous vertical burn tests:
The keyword typically refers to a standardized flammability marking found on printed circuit boards (PCBs) and internal electronic components. While many users search for an "sh1 94v-0 datasheet," this code is actually a combination of a manufacturer-specific identifier ( SH1 ) and a safety certification ( 94V-0 ).
The test is repeated multiple times. To pass V-0, the total flaming combustion time across 5 samples cannot exceed 50 seconds. 3. Why You Cannot Find a "Components Datasheet"
