Description
Известен легкоилавкий припой на основе кадмий - цинк (82,6-17,4%).Known alloy solder based on cadmium - zinc (82.6-17.4%).
Предлагаемый припой отличаетс от известного тем, что в его состав введен натрий в количестве 2-5%, а остальные компоненты вз ты в следующем соотношении в %: кадмий 75-87, 1ЦИНК 10-20. Это придает припою самофлюсующие и геттерные свойства.The proposed solder differs from the known one in that sodium in the amount of 2-5% is introduced into its composition, and the remaining components are taken in the following ratio in%: cadmium 75-87, 1-CINC 10-20. This gives the solder self-fluxing and getter properties.
Отличие состоит также и в том, что в состав припо может .быть также введено серебро в количестве до 3%.The difference also lies in the fact that the composition of the solder can also be introduced silver in an amount up to 3%.
Температура плавлени припо 266-270°С.Melting point solder 266-270 ° C.
Припой предназначен дл па ни никелевых , медных, золотых и серебр ных поверхностей .Solder is designed for brazing nickel, copper, gold and silver surfaces.
Восстановителем в припо х вл етс натрий , который окисл етс на воздухе при их расплавлении, восстанавлива окислы па ното металла. Врем самофлюсовани увеличиваетс при увеличении содержани натри в припое.The reducing agent in solder is sodium, which is oxidized in air as it melts, reducing the oxides of the metal trap. The self-fluxing time increases with increasing sodium content in the solder.
Припои, вл ющиес в исходном состо нии довольно хрупкими, станов тс пластичными после удалени натри из них в процессе самофлюсовани .The solders, which in the initial state are rather fragile, become plastic after removing sodium from them during the self-fluxing process.
Кроме самофлюсующихс свойств припой обладает свойствами геттера, т. е. способностью поглощать влагу. Поглотителем влаги вл етс окись натри , остающа с на поверхности припо после самофлюсовани . Если после приплавлени р-д-иерехода к кристаллодержателю прибор немедленно загерметизировать, окись натри поглотит пары воды из полости загерметизированногоIn addition to self-fluxing properties, the solder has the properties of a getter, that is, the ability to absorb moisture. The moisture absorber is sodium oxide remaining on the surface of the solder after self-fluxing. If the device is immediately sealed after the pd is welded to the crystal holder, sodium oxide will absorb water vapors from the sealed cavity
