Factors affecting the unsatisfactory quality of PCBA soldering
At present, the country has higher и higher requirements for environmental protection and greater efforts in link governance. Это как вызов, так и возможность завод PCB. If завод PCB решимость решить проблему загрязнения окружающей среды, then FPC flexible circuit board products can be at the forefront of the market, and завод PCB can get opportunities for further development.
PCBA является неотъемлемой частью электронной продукции. The performance of PCBA affects the realization of electronic products. поэтому, the production process of circuit boards is demanding. например, during the welding process of circuit boards, если не сварить, it will directly affect electronic components. Параметры платы не могут нормально работать. The following describes the factors that affect the welding quality of the PCB board:
1. состав и сварочные свойства сварочных материалов.
Circuit board welding mainly includes electrodes, припой и другие соответствующие сварочные материалы. The composition and performance of these materials will directly affect the quality of circuit board welding. Кроме того, it is also noted that the chemical reaction during the welding process is the chemical reaction during the welding process, среди них плата является важной частью технологии сварки, the main function is the role of the channel connecting the circuit board.

2. Welding method.
при сварке платы, it is necessary to select the soldering method according to the specific situation. основная причина заключается в том, что выбор производится по различным точкам плавления припоя. Remember that you cannot choose the soldering material. во время сварки, the soldering process that is higher than the melting point is lower. Вообще говоря, we can choose white rosin and isopropanol solvent.удаление флюса через теплопроводность, corroding the circuit board, заваривать поверхность на платы.
3. температура сварки.
The soldering temperature of the circuit board is also an important factor affecting the quality of soldering. если температура сварки завышена, the dispersion speed of the solder melt will increase, Деятельность увеличится, плата также ускоряет окислительную реакцию расплавленного припоя, which will eventually lead to the circuit board soldering quality that does not meet the requirements. требования.
4. поверхность платы чистая.
If the surface of the circuit board is not clean enough, будет осколок, which directly enters the tin can and becomes a tin ball, оловянный шар тускнеет.. Therefore, чистота поверхности платы также непосредственно влияет на качество сварки.
