Do you know what a BGA repair table does? Today, let Shenzhen Da Tai Feng Xiaobian explain to you:
You know what a BGA chip is? It's a flip chip! With lead/unleaded tin ball as the pin, generally the tin ball is wrong, the pin does not work properly, resulting in the whole board does not work properly.
At this time, the BGA chip needs to be removed from the PCB board. This is the BGA repair table, which is the meaning of the machine.
The heat gun is a hot air out of the mouth, and the repair platform is heated in three places at the same time. The two mouths are respectively heated up and down the chip, and the third is heated for the whole PCB board.
Because of the coefficient of thermal expansion, if the whole PCB board is not heated, the board is easy to deformation or unequal heating, and of course, a little moisture can be removed.
BGA repair table is an upgraded, modified process heat gun! It's really hard for people to understand
Or you could view it that way
BGA repair table is a reheating and welding equipment corresponding to the poorly welded BGA. It can not repair the quality problems of the BGA components themselves. However, according to the current technology level, the probability of BGA components factory problems is very low. If there is any problem, the welding defects caused by temperature will only occur at the SMT process end and back section, such as air welding, false welding, false welding, soldering and other welding problems. But many individuals repair laptops, mobile phones, XBOX, desktop motherboards, etc., will also use it.
Well, the above is the introduction of what the BGA repair platform is to do. I hope it can help you ~
