Industrial Electronics Competition Overview This WorldSkills UK competition focuses on all the essential requirements for a successful career in industrial electronics. Competitors undertake the role of an electronics technician and are required to work to industry recognised standards. The competition is largely practical, however, competitors will be required to have a thorough understanding of design principles and theory associated with the fundamentals of electrical, analogue, and digital principles.

Module 4 - Assembly module Competitors shall be able to: Assembling and utilising mechanical parts such as DC Motor, Fan Motor, Solenode, bolt, nut, washer and etc Wire and form cables Assemble and use various types of parts and SMD part General Instructions 1. Maximum working time is 7 hours at regional heats and 11 at the National Final 2. At the start of the competition an allotted time will be allocated for work planning. This time is not part of the working time. 3. The competition will consist of 4 module(s). 4. All supplied equipment and materials must be accurately checked by the competitor upon commencing the competition. 5. All materials and equipment must be marked out/used in the most economical method. 6. Competitors will lose marks for any misplaced, lost or spoiled materials and/or equipment, where this is the result of competitor error. 7. Minimum marks will not be awarded for dimensional accuracy or technical perfection where instructions have been disobeyed Marking Criteria Please note this is an example of how marks will be awarded.

You will be required to re-draw the circuit diagram shown in Figure 1 with changes. The completed circuit diagram should be stored on your memory device and a hard copy of the final circuit design printed out. 2. Neatly Build the circuit onto a 'Prototype board' using the layout supplied. 3. Apply the correct power and measure and record the circuit frequency. 4. Demonstrate a working circuit to a judge. Marks at Regional competition will be awarded for: a. Completed and correct schematic diagram of the Pre-competition task. b. Neatly constructed layout of components and wiring onto a prototype board. c. Recorded output data values of the signal amplitude and frequency. Note: i. All components for the Schematic Design will be of conventional ‘through hole’ type. II. The competition task is to produce the schematic diagram ONLY and construct a working circuit onto a prototype board. III.
