HAL (Free Free), полное имя - это выравнивание горячего воздуха с лидером. По сравнению с HASL основным отличием для HAL (Free Free) является элемент материала, который не содержит свинца (PB), поэтому он соответствует, и он намного популярна и широко используется вPCB производствоОтказ

HAL (Free Free) требует более высоких температур прогона для приводит к свинцам припоя и более длительное время соприкосновения, стоимость производства для HAL (без свинца) немного выше, чем hasl (олово / свинец).

Процесс изготовления HAL (Free Free Free) аналогичен HASL (олово / свинцу), цепные платы будут погружены в расплавленную припоя (свинца). Этот припой будет охватывать все открытые медные поверхности. При отвлечении от припоя горячий воздух высокого давления влюбится на поверхность через воздушные ножи, это повышает осадок припоя и удаляет избыток припой с поверхности печатных плат.

Типичная толщина HAL (Free Free) составляет 1-40um, а срок годности 12 месяцев.

Преимущества Hal (Free Free) поверхности

● хорошая пайка / смачиваемость
● соответствует ROHS
● Хорошие свойства отравляют
● Допускается большое обработка окна
● несколько тепловых экскурсий
● может быть широко используется

Недостатки отдела поверхности HAL (Free)

● неровная поверхность
● не подходит для печатных плат с мелким шагом
● тепловой шок
● припой мост
● подключен или уменьшается с помощью отверстий

A-Tech имеет Hal (Free Free Free) отделка поверхности в доме, в основном самая высокая доля отделки, используемая для монтажных досок без мелкого шага или макета высокой плотности. У нас нет никаких дополнительных расходов на конец поверхности HAL (Free Free).
