resistors:
They are placed in vertical position.
The body of the resistor goes on top of the white circle marked on the PCB.
tip: they don’t have a polarity; this precaution is due to avoid them touching while soldered.
R6, R15, R17, R22, R24, R26, R35
R7, R11, R19, R20, R25, R30, R36
transistors:
The “D” shape white symbol on the PCB needs to be aligned with the “D” shape of the transistor that
needs to be soldered.
ICs:
Place the sockets matching the drawings on the PCB, be careful of the notch direction.
tip: flip the board, bend one of the socket legs and solder that leg. Check if the socket is
aligned with the PCB. If so solder all the other pins.
Place the ICs and be careful of the notch direction.
headers:
Short legs are what needs to be soldered: Insert the short legs inside the hole.
Always check if you are on the right side of the board by looking at the drawings and texts on the
PCB: the header’s body needs to match the drawing on the PCB.
tip: solder one pin and check if the header row is aligned and perfectly vertical with the PCB.
If so solder all the other pins.
you deserve a good cup of coffee now
done?
ok, flip the board
