Which is better, Anji Technology's electroplating solution or Shanghai Xinyang's?

The electroplating solution in Xinyang, Shanghai is better. Anji Technology Co., Ltd. was established in 2007, focusing on the research of chemical mechanical polishing solution and solar cell modules in the circuit field. Shanghai Xinyang was established in 1999, and its main business is integrated circuit manufacturing and advanced packaging of key process materials. The copper sulfate electroplating solution successfully entered the SMIC center liquid supply system. Therefore, the electroplating solution in Xinyang, Shanghai is better. Electroplating solution mainly includes main salt, conductive salt and complexing agent, which can improve the upper limit of working current density and buffer.
