Everything you've always want knows about:
“Design and Building 
of a Power Supply”
Objectives
Design and building a Power Supply. 
The project is very important for improve the skills in 
courses of electronics for professional schools. The 
Power Supply is used to testing of equipments and 
circuits designed by students.
The 4 Steps / The 4 Days
Step #1 - “Design of The Power Supply”
Step #2 - “Building of The Impressed Circuit Board and
Soldering of The Components”
Step #3 – “Testing and calibration of the Power Supply”
Step #4 – “Building of The Cover and General Adjuster”
First Day:
“Design of The Power Supply”
It is not a kit!

Do I need to 
buy 
everything?
How much is it?

Second Day:
“Building of the Impressed Circuit Board and
Soldering of the Components”
The Model of Circuit Board
Impressed Side
Components Side
Check the length and size of components
Check The length and size of components
in impressed side 
Check The length and size of board
Cut the board
Use machines…
Match the points with pencil
Draw with a special pen
Another technical… with Photo Offset Paper!
Impress the Board in to Photo Offset Paper
Use a “Pressing Iron” to burning the paper
Check the impressed lines
Use a “magnifying glass” to find errors

Can I Help 
You?
Dive the Board in Percloreto’s Liquid
After few minutes…
Am I a dirt kid?
Don't forget the clean board!
You need to see the shine!
Don't forget the testing of lines…
Prepare to drill the board…
Pick up all components…
Drill of the board… 
….but check of length and size of components
