2 1 Module Title Printed Circuit Board Design And Fabrication 2 Module Code N Level 4 Credit Value 1 credit Purpose This module is a statement of the standards to be achieved to gain an FETAC credit in Printed Circuit Board Design and Fabrication at level. The module is designed to give the learner an understanding of the processes involved in P.C.B. design and production. The module is best delivered with analogue and digital electronics level. 6 Preferred Entry Level Leaving Certificate or equivalent qualifications and/or relevant life and work experiences. 7 Special Requirements None. 8 General Aims Learners who successfully complete this module will: 8.1 be familiar with the computer-aided draughting design software package 8.2 be confident users of this computer design technology 8.3 be capable of using the software to produce a schematic and layout diagram from a given circuit diagram 8.4 be familiar with of the relevant industrial processes to transfer the design to a copper clad board and produce a bare printed circuit board 2

The module is best delivered with analogue and digital electronics level. 6 Preferred Entry Level Leaving Certificate or equivalent qualifications and/or relevant life and work experiences.

3 8. develop an awareness of the various finishing processes involved in producing the finished P.C.B. 9 Units The specific learning outcomes are grouped into unit(s). Unit 1 Unit 2 Unit 3 Unit 4 Unit Schematic CAD Software Board Layout CAD Software Transfer and developing of artwork Board etching, drilling and finishing Health and safety 10 Specific Learning Outcomes Unit 1 Schematic CAD Software manipulate the design software use the pull down menu environment setup a new project understand the use of the required library files add components such as resistors, capacitors, diodes, transistors and connectors to the drawing label each component link these in an appropriate fashion using the tracks save and print the file modify the drawing using various commands Unit 2 Board Layout CAD Software set the board outlines place the components on the board set up appropriate parameters and draw tracks use edit commands to move and delete items adjust track widths adjust track shape understand the use of layers 3

Outcomes Unit 1 Schematic CAD Software 10.1.1 manipulate the design software 10.1.2 use the pull down menu environment 10.1.3 setup a new project 10.1.4 understand the use of the required library files 10.

4 display all or individual layers be aware of the print properties available to alter size and definition appreciate the various material and their properties that can be used for transparencies print the final artwork Unit 3 Transfer and developing of artwork distinguish single and double sided P.C.B board understand the photographic method used to produce the image explain the role of photoresist appreciate the advantages of pre-sensitised boards measure and cut the board to an appropriate size expose the artwork and board in an ultraviolet light box develop the image using the required chemicals wash the finished image observe appropriate health and safety procedures Unit 4 Board etching, drilling and finishing discuss the features of an etch tank know the chemical compounds that can be used to etch a P.C.B compare the properties of these chemicals etch a board using an etch tank compare the use of abrasives to chemicals for stripping photo resist remove photoresist mask drill the board using the correct size drill bit for each component understand the advantages of tin plating appreciate the advantages of using flux and protective coating.. sprays observe appropriate health and safety measures. 4

3.4 appreciate the advantages of pre-sensitised boards 10.3. measure and cut the board to an appropriate size 10.3.6 expose the artwork and board in an ultraviolet light box 10.3.7 develop the image using the required chemicals 10.

5 Unit Health and Safety appreciate the dangers of working with ultraviolet light sources develop safe procedures when using a light box be aware of the dangers of corrosive chemicals know how to dress using the correct protective clothing & eye protection 10.. know how to deal with an emergency situation. 11 Portfolio of Assessment Please refer to the glossary of assessment techniques and the note on assessment principles at the end of this module descriptor. All assessment is carried out in accordance with FETAC regulations. Assessment is devised by the internal assessor, with external moderation by FETAC. Summary Skills Demonstration 0% Project 0% 11.1 Project The internal assessor will devise a project brief that requires candidates to demonstrate (a) CAD skills in layout and editin g of a schematic and board layout diagram for a given circuit. (b)board production and finishing to a high standard 11.2 Skills Demonstration In one or more skills demonstrations, candidates will be assessed in production of schematic drawings, board layout drawings, board fabrication skills
