Progress assessment

Evaluation of laboratory works - max 25 points, test 1st - max 10 points, test 2nd - max 15 points, final written examination - max 40 points, oral final examination - max 10 points. Written and oral part of final examination are duty. Progress to oral part of final examination is only after receiving min 15 points from written part of final examination. Oral part of final examination is passed with min 4 points.
Examination is oriented to evaluation of received knowledges from printed circuit board (PCB) production and surface mount technology (SMT) topics and in practical orientation in technology analysis of real assembled PCB. Student in this analysis demonstrates ability to choose conforming technology procedure of components assembly and of PCB description incl. applied PCB surface treatments.
