I already said in the training course article.
it will be 3 to 4 weeks if you totally don’t have experience of micro-soldering.
Theories class is short. But skills training a lot. You can learn a lot of secret skills.
If you don’t have much time, at least you need two weeks. You can come back to continue skills training later. Because two weeks is enough for me to teach theories, troubleshoot, CPU swapping…
