Mech can work in semicon area lah, as a design engineer, with autocad lah of course...not the ic designer, dun mix up. Besides that, u can also be a researcher if the organization do has this department, aim for micoelectronics and mechanical system (MEMS).

programming requires logical thinking, meaning u can visualize the flow of ur program in ur mind. Sometimes u need maths for ur programming when u need to do a system for cyber cafe or fast food outlets. Programming needs to do a lot of counters, case that need maths also......but not as much as in engineering lah
