How wrong steps in soldering effects copper pad

This is taken on the evening of 29 June 2024. Where wrong steps in soldering effects the copper pad on the latch part of the board.

This makes the programmed number 2 on the third unit of 7-segment unable to display the E pin.

The look of the empty microprocessor board before being assembled on morning 28 June 2024.

The look of the PCB (Printed Circuit Board) lab full of 3 groups assembling their board. In the morning of 1 July 2024.

Taken on the noon of 30 June 2024.

Lesson learned well. Need to use lower power heat gun.

Until then, be careful while assembling electronic components on microprocessor board.
