Abstract

Использование: влагозащита печатных плат. Сущность изобретени : после сушки при температуре 110°С и охлаждени  до комнатной температуры, печатную плату погружают в емкость с анаэробной композицией с последующей термообработкой при температуре 120-130°С в течение 20-30 мин.Usage: moisture protection of printed circuit boards. SUMMARY OF THE INVENTION: After drying at a temperature of 110 ° C and cooling to room temperature, the printed circuit board is immersed in a container with an anaerobic composition, followed by heat treatment at a temperature of 120-130 ° C for 20-30 minutes.

Description

Изобретение относитс  к технологии изготовлени  печатных плат и может быть использовано дл  влагозащиты печатных плат.The invention relates to the technology of manufacturing printed circuit boards and can be used for moisture protection of printed circuit boards.

Цель изобретени  - повышение надеж- йости и долговечности печатных плат.The purpose of the invention is to increase the reliability and durability of printed circuit boards.

Сущность изобретени  заключаетс  в следующем.The invention is as follows.

Печатную плату сушат в сушильном шкафу при температуре 110°С в течение 30- 40 мин. После охлаждени  до комнатной температуры ее погружают в емкость с анаэробной композицией, с выдержкой в течение 1-2 ч и последующей термообработкой при температуре 120-130°С в течение 20-30 мин.The circuit board is dried in an oven at a temperature of 110 ° C for 30-40 minutes. After cooling to room temperature, it is immersed in a container with an anaerobic composition, with exposure for 1-2 hours and subsequent heat treatment at a temperature of 120-130 ° C for 20-30 minutes.
