Introduction

iFixit Soldering Guide

Do you need to remove the circuit board, motor, belts, or buttons on your TCM-450? Then you will need this guide to get to those parts. The PCB, motherboard, or circuit board for TCM-450 hides all of the important mechanical components that make TCM-450 work, and is the computer board that runs the device. This may be difficult because you desolder multiple wires to lift up the PCB.

    • Remove the two 3.5 mm Phillips #00 screws from the bottom of the device.

    • Caution: Ensure the device is off and unplugged if using the power adapter, as it is unsafe to remove the cabinet while on and will cause damage and potential harm to the user.

    • Open the battery cover, and gently remove the back cabinet with the iFixit Opening tool.

    • The device will make a popping sound when removing the back cabinet. The back cabinet may feel as if it is not loose. However, as long as the back cabinet looks disconnected from the lid, it is safe to remove.

    • Carefully desolder each connection and gently remove each connected wire.

    • If you are unfamiliar with desoldering and soldering, please consult the iFixit Soldering Guide.

    • Make sure the soldering iron is 50 watts as 30-40 watt soldering irons will not melt the solder on the PCB.
