海洋仪器是从事海洋调查不可缺少的重要工具。特别是些电子仪器主要组成部份是印刷装配板,因此在高湿高盐雾环境下容易引起仪器故障及元器件破坏,经过几年实践,采用有机涂层保护印刷装配板,取得了一定效果,引起了电子仪器设计者的足够重视,感到这种防潮涂料是不可少的,对提高仪器的可靠性,起到积极作用,然而有的同志却忽略了印刷线路板的选材与焊接,不但影响了涂复效果,也降低了产品的质量。为此,就选材和焊接谈谈个人看法。
Marine instruments are an indispensable tool for oceanographic investigations. In particular, some of the main components of electronic instruments are printed assembly board, so high humidity and salt spray environment easily lead to instrument failure and damage to components, after several years of practice, the use of organic coating to protect the printed assembly board, and achieved some results , Attracted enough attention of electronic equipment designers feel this kind of moisture-proof coating is essential to improve the reliability of the instrument, play a positive role, however, some comrades ignored the selection of printed circuit board and welding, not only affect The Tu Fu effect, but also reduces the quality of the product. To this end, on the selection and welding talk personal opinion.
