过去,在制造薄膜固定电阻器时,先在陶瓷骨体表面用氟化氢等药品人工处理成凹凸面,然后将电阻膜置于槽内,以提高电阻膜的固定强度。但是,这种方法却难以完全清除骨体表面所用的处理药品。由于残留药品的作用,对电阻器的电气特性产生不良影响。此外,为了保护电阻膜,在电阻膜表面用笔涂或浸渍等方法上一层薄薄的树脂绝缘膜。可是,电阻膜形成后,骨体从炉中取出挪动至给进装置或其它容器,以进行绝缘膜的加工。在挪动过程中,会在电阻膜上附着
In the past, when manufacturing a thin-film fixed resistor, the surface of the ceramic body was artificially treated with a drug such as hydrogen fluoride into a concave-convex surface, and then the resistance film was placed in the groove to improve the fixing strength of the resistance film. However, this method is difficult to completely remove the treatment of the body surface of the drug used. The residual electrical properties adversely affect the electrical characteristics of the resistor. In addition, in order to protect the resistive film, a thin resin insulating film is coated on the resistive film by pen coating or dipping. However, after the formation of the resistive film, the bone body is removed from the oven and moved to the feeding device or other container for the processing of the insulating film. In the process of moving, will be attached to the resistance film
