Are you looking for PCB design interviews questions ? Here are some interesting questions and answers

Technical interview:

Q.NO.1:  Explain the flow diagram of the PCB design.

Q.NO.2 : How will you create a footprint in your PCB designer software (say, Altium)?  

Q.NO.3: What are fiducials? Explain the use of these fiducials, their types and differences between them. Explain in brief about the fiducial placement and clearances. What are the clearances you have given from board outline to route and place keeping areas.

Q.NO.4: What are the errors you got while importing netlist?

Q.NO.5: How will you define design rules? How do place components?

Q.NO.6: How do you plan routing? Mention the parameters you consider while routing

1. Flow of complete PCB Design ?

Ans:

1. Input collection
2. Data sheet
3. BOM
4. Library creation
5. Schematic capture
6. Design rule check
7. Net list, Approval.
8. Layout details
9. Major component location
10. Placement
11. Further requirement of client
12. Routing
13. Critical signals, Differential pair
14. Copper pouring
15. Design rule check
16. Output files generation

That's all about PCB design flow.

2. What are the inputs you need to design a PCB ?

• We need schematics, BOM and netlist(some pcb engineer generates netlist) from Hardware side and board mechanical from client. i.e board outline, mounting holes etc. 
• and another important thing that we need pcb stackup .it is based on complexity of the board . for example if we are using FPGA  first we should know number of signal layers need for FPGA signal breakout.
