光化学腐蚀技术除广泛用于制造各种各样的印制板及五光十色的标牌外,还越来越多地用于代替机械加工。早在第二次世界大战时期就开始用光化学腐蚀法制造枪炮瞄准器。国外常用光化学腐蚀法制造机械零件的初样,如:记录头,装在彩色显像管的不锈钢荫罩,马达叠片,成型模具,径向或轴向弹簧、阀门等。 In addition to being widely used in the manufacture of a wide variety of printed boards and colorful labels, photochemical etching technology is also increasingly being used in place of machining. As early as World War II began to use photochemical etching method to manufacture gunsight sight. Foreign common use of photochemical corrosion of the manufacture of mechanical parts of the first kind, such as: recording head, mounted on the color CRT stainless steel mask, motor laminations, forming molds, radial or axial spring, valves.
