Scenario

Scenario: You have been asked by your employer to design a single and multi-layered prototype PCB using PCB design and simulation software.  You are required to consider relevant manufacturing techniques for both single and multi-layered PCB in the form of a written report 

Task 1

1. Build the circuit below:

2. Describe the following:

  I. How the component values are changed  

  II. Show how to convert to art work by auto routing and the relevant parts list

 III. Show how to verify the design and carry out a Design Rule Check

3. Describe the additional processes required to produce a  multilayer PCB, include in the descriptions microprocessor bus systems, power tracks being separated from signal tracks.

Evidence you must produce for this task

Written report describing in technical detail the information requested above.  Include screenshots of the circuit being built and the testing and verification process

Criteria covered by this task:

To achieve the criteria you must show that you are able to:

Unit

Criterion reference

Describe the processes used in the design of both a single and multi-layer PCB for electronic circuits of different complexity

P1

Task 2

Below is a typical production method used in the manufacture of a single layer PCB for an electronic circuit.  Your task is to explain each section.

1. The design layout
2. Producing the artwork
3. PCB Etching
4. Drilling the Board
5. Populating the board and soldering

Below is a typical production method used in the manufacture of a multi-layer PCB for an electronic circuit.  Your task is to explain the manufacturing route from the beginning of production to completion.
