Question 3: What is the purpose of a de-paneling tool in PCB assembly?

Which action should you take?

Choose only one option

To remove solder from the PCB after assembly

To cut and shape the PCB before assembly

To etch the PCB with precise designs for component placement

To separate individual PCBs from a larger sheet without damaging the components or PCB layers

Question 4: How does using an incorrect soldering iron temperature affect the quality of a solder joint?

Which action should you take?

Choose only one option

It enhances the reliability of the joint by preventing overheating

It reduces the overall time needed for soldering

It can lead to weak joints, poor adhesion, and increased likelihood of cold solder joints

It has no significant effect if the soldering iron is clean and well-maintained

Which action should you take?

Choose only one option

Optimize stencil design for solder paste

Use lead-free solder

Increase reflow oven temperature

Use of stencils with larger apertures
