There are currently no corresponding international and national standards for solder resist for printed boards and marking inks for printed boards. The original industry standard SJ / T 10309-1992 "Solder Mask for Printed Boards" is obviously obsolete. In order to meet the needs of manufacturers and users in the inspection, acceptance, and identification of this product, the China Printed Circuit Industry Association (CPCA) commissioned Guangzhou Panyu Guangxin Silkscreen Material Co., Ltd. to undertake the formulation of these two standards in August 2009. . The standard combines the actual conditions in China and refers to the IPC-SM-840D and IPC-4781 formulated by the American Electronics Industry Connection Association. During the formulation process, JPCA actively participated in the discussion and proposed many amendments. It eventually became a joint standard of JPCA and CPCA, and was jointly released in March this year.

"Solder Mask for Printed Circuits" and "Marking Ink for Printed Circuits" make specific requirements on the performance requirements, inspection methods, inspection rules, packaging, marking, storage and transportation of solder masks and marking inks for printed boards, respectively. . These two standards play an important guiding role in the research, production and application of solder resist for printed boards and marking ink materials.
