Is it difficult to learn SMT mounter without knowing English?

Not difficult. Today's machines are fools, and can be converted into simplified Chinese version, English version and Japanese version. To tell the truth, as long as you work hard 1 month, you can be an SMT technician. I studied SMT for 3 months before and was directly promoted to SMT engineer. If I am a SMT senior engineer, it will take 2 years. You mainly study hard by yourself. Without hard work, you haven't made progress for a year.
