1. Standard high-brightness LED circuit boards mainly describe the quality requirements for certain specific items of high-brightness LED circuit board products, and explain the acceptable specifications for each specific product item; 2. Standard high-brightness LED use printing The circuit board test method mainly explains the test methods for the reliability test items of circuit board products for high-brightness LEDs, and explains the judgment criteria for each test item. ------- The main technical changes in this standard are as follows:
——Added reference to the national standard "Printed Circuit Terminology" in the standard to make it more suitable for domestic enterprises;
——Added the 2.2 Terms and Definitions section, and added the reference to " Definition of terms such as "vertical thermal conductivity parameter" and "horizontal thermal conductivity parameter";
——JIS C will be quoted
