The Correct way to use an electric пайка утюг должен быть a пятиступенчатый метод:
Готов для сварки
Подготовка припой провод и пайка утюг. В это время, it is particularly подчеркивается that the tip of the пайка утюг должен быть хранить чистый, that is, it can be stained with solder (обычно известный как есть олово).
Нагрев сварной шов
Touch the пайка утюг к пайка точка, pay attention to keep the пайка утюг нагрев все детали of the сварка, for example, the lead wire and pad on the printed board are heated, and then pay attention to let the flat part (large part) of the solder solder iron tip contact the larger heat capacity The weldment, the side or edge of the solder solder iron tip is in contact with В сварка с A маленький тепло емкость к держать сварка равномерно нагретый.
Когда сварка есть нагретый до а температура тот расплавы пай и провод есть размещенный на пай соединение, те пайка начинает к расплавить и влажный пай пайка соединение.
remove припой
Удалить припой провод после а определенная сумма припоя имеет расплавленный.
remove the пайка железо
Когда припой имеет полностью смачивается пай соединение, удалить пайка утюг. Примечание что в направление удаление в пайка пайка утюг должен быть приблизительно 45 градус .
The above process takes about two or three seconds for general solder joints. for solder joints with small heat capacity, such as small pads on printed circuit boards, sometimes a three-step method is used to sum the operation method, that is, is, is, the above steps 2 and 3 are combined into one step, and steps 4 and 5 are combined into one step. В факт, the subtle distinction is still five steps, so the five-step method is universal and is the basic method for mastering manual пайка железо сварка. In particular, the time spent between each step is crucial to ensure the quality of welding, and it can only be mastered gradually through practice.
Сварка Технология
1. Как к удерживать пайка утюг
(1) How to hold a pen. Fitable for lightweight пайка утюги such as 30W internal heating. Its пайка утюг головка is straight, and the head end is filed into a bevel or conical shape, which is suitable for solder pads with a small area.
(2), fist method. It is suitable for high-power паяльник утюги. We generally do not use high-power паяльник утюги for electronic production (not введенный здесь).
2. Несколько методы из пайка выводы на печать печатная плата платы.
There are two types of printed circuit boards: односторонний and двусторонний. The through отверстия on it are generally non-metalized, but in order to make the components sпая on the печатная плата more firmly and reнадежны, most of the through holes of the printed circuit boards of electronic products are now metalized. The method of soldering the leads on the ordinary single-sided board:
(1) Прямой сквозной режущий головка. The lead wire goes through the through hole direct. When soldering, an appropriate amount of molten solder is equally surrounded by the tinned lead wire above the pad to form a cone shape. After it is cooled and hardified, the excess lead wire is cut off. (см. the blackboard for the specific method)
(2), buried directly. The lead through the hole is only exposed to an appropriate length, and the molten solder buries the lead tip inside the solder joint. This kind of solder joint is approximately hemispherical. Although it is beautiful, special attention should be paid to prevent false soldering.
3. Предотвратить плохо сварка
Пайка есть a базовый навык что радио любители должен мастер, and it берет a lot of practice to master it.
