Description

Пример 2. Приготавливают 3%-ный раствор этиленгликольмоностеарата в четыреххлористом углероде л погружают в пего серебр ное изделие на 10 сек; при извлечении на воздух на поверхности образуетс  однородна  защитна  нленка, котора  не вли ет на способность к пайке. Переходное сопротивление возрастает незпачительно (на 3- 6%).Example 2. A 3% solution of ethylene glycol monostearate in carbon tetrachloride is prepared and dipped in a silver product for 10 seconds; when extracted to the air, a uniform protective film is formed on the surface, which does not affect the solderability. Transient resistance increases without an increase (by 3–6%).
