What is the primary purpose of welding

• To cut materials

• To bond materials together

• To shape materials

• To clean materials

Which welding process uses a non-consumable tungsten electrode?

• MIG welding

• TIG welding

• Arc welding

• Gas welding

What does the acronym "TIG" stand for in TIG welding?

• Torch Inert Gas

• Tungsten Inert Gas

• Thermal Inert Gas

• 1. Transformer Inert Gas

Which type of welding is commonly used for creating permanent connections on heavy metals like steel and iron?

• TIG welding

• MIG welding

• Stick welding

• Gas welding

In welding, what is the purpose of a "welding mask"?

• To provide shade for the welder

• To protect the welder's eyes from UV radiation

• To regulate the flow of gas

• To provide oxygen for combustion

What does PCB stand for in electronics?

• Printed Circuit Board

• Personal Computer Base

• Plastic Component Block

• Printed Chip Board

What material is commonly used as the base substrate in PCBs?

• Aluminium

• Glass-reinforced plastic

• Steel

• Copper

Which process is used to attach electronic components to a PCB?

• Welding

• Soldering

• Riveting

• Gluing

What role do copper tracks play on a PCB?

• They hold the components in place

• They provide structural support

• They conduct electrical signals between components

• They insulate the components

Why might you simulate or prototype a PCB?

• To verify and test the functionality of the circuit design before production

• To optimize the circuit's performance by making adjustments and refinements

• To increase production costs by identifying and correcting errors early in the design process

• To avoid the troubleshooting process and rely solely on the final production
