NOTE:
1) Because the 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: >8H). Otherwise 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.
