SD Board

Now it’s time for a little challenge. Solder the SD card holder to its little board. It is SMD component but

don’t let that scare you, it’s pretty simple. A fine tip soldering iron is suggested here.

Then carefully place the card holder on top and make sure it's aligned properly, maybe hold in place with

tweezers. Solder the top side pads to make the card holder stick to the board, check that the holder sits flat

on the board. Carefully solder the rest of the leads, by placing the soldering iron perpendicular to the edge

of the lead and applying solder to the pad. Make sure that they don't bridge.

Alternatively you can apply some solder to all the pads before

placing the card holder and then re heat them.

Super mega important!!! Respect chip polarity.

Before connecting the boards together again, insert the IC chips into their sockets of the bottom board.

Again make sure that the

notch

on the chips is

facing the same direction

as the notch on the sockets.
