[Company News]BGA rework process2019/12/07/ 10:21: Since the solder joint of the BGA is at the bottom of the device, it is invisible, so it is more difficult to rework compared to QFP and other peripheral pins. It is not a big problem when disassembling the BGA. However, when re-soldering the BGA, the rework system is required to be equipped with a spectroscopic vision system (also known as the bottom reflection optical system) to ensure accurate centering when mounting the BGA. The equipment suitable for rework BGA includes hot air rework station, infrared heating rework station, hot air Infrared rework system, etc.; Read（0） Label：PCB BGA| pcb prototype| pcb assembly| pcb manufacturing| pcb factory| pcb online

[Company News]Soldering iron tips correct selection and maintenance2019/12/05/ 10:55: The correct choice of the flame iron head can achieve better welding at the lowest temperature, and maximize the service life of the iron head. The main reasons for PCB manufacturers to choose flame iron heads are as follows. Select the proper shape of the soldering iron tip according to the type of the component to be soldered. For example: when disassembling SOIC, a two-piece flat-shovel horseshoe-shaped iron head should be selected, and when removing QFP / PLCC, a square-shaped soldering iron head should be selected. Select a soldering iron tip of appropriate size according to the size of the solder joints of the component being welded, for example: a small solder joint can use a conical grid iron; Read（0） Label：pcb manufacturing| pcb manufacture| pcb prototype| pcb assemble| make circuit board
