Погружениеное золото или Enig, полное имя - это электрическое никелевое / погружение в погружение, это соотеченность, соответствующая RoHS, которая обеспечивает очень плоскую поверхность и очень надежное припоедение.

Отделка ENIG применяется через осаждение начального слоя никеля на поверхность меди, а затем тонкий защитный слой золота, никельские характеристики твердости, износостойкость, паянию и равномерность осаждения делает эту превосходную поверхность. Тонкий слой золота сохраняет паябильность финиша путем предотвращения окисления высокоактивной поверхности никеля.

В основном толщина золота ENIG составляет 1-5U, а толщина никеля составляет 120-240U ", срок годности погружения погружения Gold PCB может достигать 12 месяцев.
