What is a PCB?

What does PCB stand for?

• Partially Completed Branding

• Printed Circuit Board

• Pastries with Cream and Butter

What was NOT an issue that old circuits had?

• 
  

  They were very loud and made a lot of noise

• They were very complex and hard to repair

• They were hard to manufacture and could not be mass produced

How are PCBs different from older circuits?

• They are large wooden boards that can have many wires inside of them

• They are made with tubes instead of wires

• They are non-conductive boards have a copper circuit printed onto them

The main part of a PCB is made out of...

(a)  

The first step in the creation of a PCB is...

• drilling holes that will be used to attach components

• submerging the copper in a bath of liquid tin

• installing the copper into a computer

Covering the copper plate in a resistive mask is called...

• etching

• covering
• insulating
• masking

Etching is a process where...

• Copper that is part of the circuit is added to the PCB

• Copper that is not part of the circuit is dissolved from a PCB

• Copper is transformed into a yellow copper-oxide compound

Why are PCBs usually green?

• Green is the color of progress!

• Green helps the PCB to absorb electricity from the environment

• Green is the color of the coating that protects the PCB from damage
