- Page 7 五 Operations: 、 1、Preheat Preheat the PCB board and BGA chip, and the temperature of constant temperature oven is set at 80 ℃ -100 ℃, for 4-8 hours to remove internal moisture of the PCB and BGA, to prevent the burst phenomenon when heating.
- Page 8 (2) short circuit： When the ball reached the melting point,it is in a liquid state , if too long or too high temperature and pressure,it will destroy surface tension of solder balls and the supporting role, resulting in short-circuit phenomenon when reflows,the chips fall entirely on the PCB pads the , so we need to appropriately reduce the heating section of the third and fourth soldering temperature and time , or reduce the bottom of the preheat temperature.

Page 20: Concluding Remarks
unusual, it should stop the BGA chip installation and test the temperature, and it has to be adjusted properly before welding, otherwise it will be damage the BGA chip or PCB board. 6. The machine surface needs to be clean at regular time, especially the infrared heating board. Avoid the dirt stay on the board, because the dirt can lead to heat radiation un-normally, bad welding quality and shorten the using time of infrared heating element. -
