  • Orient the microcontroller with its outline (labeled U1) on the circuit board, so the circle on microcontroller is on top of the circle on the board.

  • The indented circle on the microcontroller should be facing the same corner as the dot next to the U1 label on the board.

  • Align all 44 pins are aligned with their respective pads on the board.

  • Ensure the microcontroller is aligned both vertically AND horizontally. Once multiple pads are soldered, it is extremely difficult to remove the microcontroller and try again.

  • Hold the microcontroller still with tweezers and re-heat the solder from the last two steps to solder it to the board.

  • If you have polyimide tape, you can use it to hold the microcontroller still while you solder the first two leads.

将微控制器与它在电路板上的丝印（标记为 U1）对齐，使微控制器上的圆形标记与电路板上的标记重合。

芯片上的圆形凹槽应电路板 U1 标记旁的点应处在同一方位角。

对齐所有的 44 根针脚至其对应的位置。

确保微控制器在横向与纵向的针脚都与各自的焊盘对齐。如果已经有多个焊盘被固定住了，拆下微控制器再来一次将是极为困难的。

用镊子夹住微控制器并重新加热前两部镀上去的焊锡。

如果你有高温胶带，你可以在焊接前两个引脚的同时用它来固定住微控制器。
