The Modern Vocational Training Pilot (ModVoc)

National Competitions

The Development of the Trade Electronics at the SkillsFinland Competitions

The picture below illustrates the development of the trades within the trades of electricity at the Skills competitions. Electronics has been available since the beginning of the competitions and has been a target of a continuous development process. A clear differentiation of automation installation and a more traditional basic electric installation took place last year within the trade electric installation. In the future, the competition related to the networks of information technology will be differentiated to form a sector of its own.

The Development of the National Description of the Trade Electronics

The trade Electronics has been developing all the time. Below there will be a more precise description of the contents of the competitions since 2000. After 2002 the description of the trade got a precise form for the first time. On the one hand, the national description of the trade has been effected by the the international description of the trade, but, on the other hand, it has enhanced the implementation of changes and the modification of the the competition towards a more modern direction. Thus, the experience gained at a national level has made it possible to contribute to international work concerning the development of Electrinics . As to Finland, this process culminated at the Turku Skills Competitions in 2005, which functioned as a semifinal of the Helsinki WSC. The Tampere and Joensuu Skills Competitions showed this development and it is still going on although no major changes of the basic structure have been made.

Turku 2005

The changes in the description of the trade, Turku Skills competitions

For the first time, a so-called design and preparation of a printed circuit board was tested at the Turku Skills competitions in 2005. The aim was to create a whole device during the competition. The design was carried out with CAD software according to an individual choice of the competitor. The program only needs to create a so-called Gerber file that enables the control of a proto driller used in making a board. The device is dimensioned to be small, but it emphasizes a mechanical design (the nodal points of the circuit board, the sites of the mechanical components etc.) necessary for the preparation of the device. The task was a success and this type of task was applied more widely at the Tampere Skills competitions in 2006. This task area was demonstrated to international experts at the Helsinki WSC.

The design of a printed circuit board, 2 h

In this task a competitor makes on the basis of a given circuit diagram a one-sided circuit board of a maximum of 100 x 80 mm. There is a maximum of 20-30 nodal points. He/she uses normal basic components and IC circuits (max. 8 pins). One half of the components are of an axial type and the other one is of a surface mounted type. The minimum size of the surface-mounted components is 0805. A competitor may use his/her own computer and a freely chosen program (e.g. Pads and Eagle). As a result of the design he/shel creates a layout file and a Gerber file for proto drilling. A competitor then passes the Gerber file to a specialist operating the proto drilling machine, who creates a proto drilling control file on the basis of it and makes the board

Fault finding, 3 h

Fault finding is carried out in an electronic board that has been assembled for this task before. The faults are independent of each other and they can be switched on one at a time with control switches. The faults are equally both digital and analog circuits and there are 8 of them.

A proto board to be connected with an embedded system, 4 h

In this task an interface is defined for the proto board through which it is connected with a freely chosen embedded system. The electronics available on the proto board is accomplished to implement a given control task and the embedded system is provided with a necessary control software using the C language.

Assembly and testing of a printed circuit board, 2,5 h

The board designed in task 1 is assembled and tested. If the designed board is faulty the design-based mistakes are corrected.

Building and testing, 4 h

A whole electronic device is assembled using the circuit board assembled in task 4 as one part of it. The building involves packaging, wiring and soldering. The finished device is tested according to the testing instructions given and a report on the testing procedure is written.

Tampere 2006

1. Design of a printed circuit board, 2 h

In this task, a circuit board is suited for an electronic device. On the basis of a given circuit diagram a double-sided circuit board of a maximum 120 x 85 mm is designed. The circuit diagram has a maximum of 120 nodal points, the components are usual basic components and IC circuits (a maximum of 40 pins). The components are axial. The competitors may not use computers of their own. The software to be used here is installed by the competitor him/herself or by the organizer with the media distributed to the organizers. The design software is freely optional (e.g. Pads, Eagle). The result is the creation of a layout and gerber file on the basis of the designed circuit diagram for proto drilling. The gerber file is given to the specialist who is in charge of proto drilling. The specialist creates a control file for the drilling machine and makes the board. The usability of the file has to be tested before the competition (Merval).

2. Building and testing, 4 h

A whole industrial electronic device is assembled. There is packaging, wiring and soldering involved. The finished device is tested according to the testing instructions given and a report on the testing is written.

3. Assembly and testing of a circuit board, 2,5 h

The circuit board designed in task 1 is assembled and tested. If the designed card is faulty, the mistakes based on the design are corrected. In the worst case a competitor is given a ready-made circuit card on which he/she assembles the components. The assembly is carried out in a given package!

4. A programing task of an embedded system, 4 h

The board built in the previous tasks of an embedded system is a part of the usable device. The processor program available in the board may have some need of supplementary software or/and program faults. The supplementary software is acquired using the C language.

5. Fault finding, 3 h

The fault finding is carried out with the help of a fault simulator built for this task or genuine devices. The faults are independent of each other. The faults are equally of both digital and analog circuits and there are X(8-10) of them. The programing task has a separate fault finding partition.

Joensuu 2007

1. Design of a printed circuit board, 2,5 h

A given circuit diagram is used as a basis for a design of a usable circuit board in an electronic system according to given specifications. In this one-sided circuit board one surface installation component (16 pins) is used, ???loadable active and passive basic components and a microcontroller ATMEGA48-20PU.

The design software may be selected freely (e.g. Proteus, Pads, Eagle). As a result of the design a layout picture of the designed circuit board and gerber files for the drilling of the circuit board are made.

The gerber-file is saved on a memory stick and given to the specialist in charge of the drilling. The specialist prepares a control file for the drilling machine and finishes the board.

Is has to be pointed out here that the design program has to be a version for industrial? production. The organizer is not responsible of any problems related to the limitations of demoversions.

2. The assembly and testing of the device, 4 h
