In the process of PCB manufacture, etching is one of the most important steps to decide the final performances of products.
在印制电路制作过程中，蚀刻是决定电路板最终性能的最重要步骤之一。
This process is repeated multiple times to apply more layers, with careful monitoring and precise etching techniques applied to each layer, to produce the final layered chip design.
这一过程被重复多次以应用更多的层，通过仔细监测和施加到各个层的精确蚀刻技术，以产生最终的层状芯片设计。
