Description

(54) СПОСОБ ВЛАГОЗАЩИТЫ РАДИОЭЛЕКТРОННЫХ ПРИБОРОВ(54) METHOD FOR MOISTURE PROTECTION OF RADIO ELECTRONIC DEVICES

II

Изобретение относитс  к радиоэлектронному приборостроению, а именно к способам гидрофобизации печатных плат.The invention relates to electronic instrumentation, and in particular to methods of waterproofing printed circuit boards.

Известен способ, в котором изделие с целью повышени  его гидрофобных свойств обрабатывают перфторпроизводными высших кислот in.There is a method in which a product is treated with perfluoropropyl derivatives of higher acids in. In order to increase its hydrophobic properties.

Недостатком данного способа  вл етс  высока  температура сушки, что в свою очередь снижает надежность защитного покрыти , наносимого на поверхность издели .The disadvantage of this method is the high drying temperature, which in turn reduces the reliability of the protective coating applied to the surface of the product.

По основному авт.св. № 7k}k3 известен способ влагозащиты радиоэлектронных приборов, включающий последовательное нанесение на поверхность приборов лакового и кремнийорганического покрыти , причем перед нанесением кремнййоргаиического покрыти  поверхность прибора обрабатывают поверхностно активным веществом 12.According to the main auth. No. 7k} k3, there is a known method of moisture protection of electronic devices, including the sequential application of a lacquer and silicone coating to the surface of devices, and the surface of the device is treated with a surfactant 12 before applying the silicon coating.

Недостатком известного способа  вл етс  достаточно высока  температура сушки защитных пленок, что сказываетс  на качестве готовых приборов.The disadvantage of this method is the rather high drying temperature of protective films, which affects the quality of the finished devices.

Цель изобретени  - повышение надежности приборов.The purpose of the invention is to increase the reliability of devices.

Поставленна  цель достигаетс  за счет того, что согласно способу влагозащиты радиоэлектронных приборов в качестве поверхностно активного The goal is achieved due to the fact that, according to the method of moisture protection of electronic devices as surface active

10 вещества используют перфторированные кислоты полипропиленоксида, общей формулы:10 substances use perfluorinated polypropylene oxide acids, of the general formula:

Rp-(O-CF-CFq-O)- CF - СООН,Rp- (O-CF-CFq-O) - CF - COOH,
