On November 3rd, Chen Shirong, the executive vice secretary-general of GPCA, released the '2020 Guangdong Province Circuit Board Industry Development Investigation Report' at the GPCA's general meeting of all members.

From March to June 2020, the Guangdong Circuit Board Industry Association and the Shenzhen Printed Circuit Board Industry Association conducted a survey on the business operations of their members (including some non-member units) in 2019. With the strong support of the majority of member units, they obtained the sales revenue data of each enterprise (mainly referring to PCB manufacturing enterprises or factories located in Guangdong) in 2019.

Subsequently, the association invited industry senior engineers such as Zhu Datong and Zhang Jialiang to verify and organize this data, supplemented the data and development overview of each part of the enterprises, carried out various data analysis work, and summarized the list of 141 circuit board enterprises in Guangdong Province with annual revenue exceeding 100 million yuan in 2019 (collectively referred to as the 'Top 100 Circuit Board Enterprises in Guangdong').
