Description
Известен легкоплавкий припой, содержащий (в о/о): кадмий , цинк 0,5-1,5, натрий до 0,3, сурьму 1-1,5, свинец - остальное .Known low-melting solder containing (in o / o): cadmium, zinc 0.5-1.5, sodium to 0.3, antimony 1-1.5, lead - the rest.
Дл придани припою флюсующих и геттерных свойств в состав предлагаемого припо вход т Следующие компоненты (в %): кадмий 14-20, цинк 1-3, «атрий 2-5, свинец остальное.The solder includes flux and getter properties of the proposed solder. The following components (in%): cadmium 14-20, zinc 1-3, atrium 2-5, lead the rest.
Температура плавлени припо 245°С. Восстановителем в Припое вл етс натрий, который окисл етс «а воздухе При расплавлении припо , восстанавлива окислы па емого металла .Melting point solder is 245 ° C. The reducing agent in Solder is sodium, which is oxidized in air. When the solder melts, it restores the oxides of the molten metal.
Врем самофлюсовани увеличиваетс при увеличении содержани натри в припое.The self-fluxing time increases with increasing sodium content in the solder.
Кроме самофлюсующих свойств припой обладает свойствами геттера, т. е. способностью .поглощать влагу. Поглотителем влаги вл етс окИСЬ натри , остающа с на поверхностиIn addition to self-fluxing properties, the solder has the properties of a getter, that is, the ability to absorb moisture. Moisture absorber is a sodium oxide remaining on the surface.
припо после процесса самофлюсовани . После приплавлени р-л-перехода к крнсталлОдержателю , прибор следует немедленно загерметизировать . Окись натри поглотит пары воды из полости загерметизированного прибора, стабилизиру характеристики собранного прибора.solder after the self-fluxing process. After melting the p-junction to the holder, the device should be sealed immediately. The sodium oxide will absorb water vapor from the cavity of the sealed instrument, stabilizing the characteristics of the assembled instrument.
