7.2 Trouble shooting for common failures NOTE:

1) Because the main PCBA will become damp after long time storage, please use oven to bake the main

PCBA firstly if it has been stored for more than 7days (oven temperature: 105 ℃, Time:

it may cause the PCBA blister easily when you heat part of the PCBA by using hot wind gun.

2) Interchange method means using a new component to test the function in order to verify whether the

old component is defected.

3) Please use hot wind gun to reweld or disassemble/assemble the component mentioned afterwards.

(hot wind gun temperature: 330℃, Air Level: 2~3, Height: around 10mm, Time: less than 60s)

4) Before rewelding or disassembling/assembling the component, DO remember to paste high

temperature adhesive tape on the components which are close to it, in order to avoid damaging of

these components.
