First of all, it depends on how long you've been doing this job! If within 3 years you can consider completely give up this line, as long as you have the courage, then start from 0 to learn other aspects of things! 3-5 years then you can learn a bit of programming and some PLC knowledge! 5 years then you can move forward to the design side of the job from the Q-user: Mr. Liu
Either do equipment management, or do equipment design, or do the design of the cure tool from the Job Q User: Mr. Ren
This is the first time I've seen this.
