Centum Electronics Interview Questions, Process, and Tips

Yes, BOM stands for Bill of Materials and BOM scrubbing is the process of reviewing and cleaning up the BOM.

• BOM is a list of components and materials required to build a product

• BOM scrubbing involves checking for errors, duplicates, and obsolete parts

• It ensures accurate and efficient production and inventory management

• Examples of BOM scrubbing tools include Arena PLM, Omnify Empower, and SAP PLM

Yes, I validate the MPN & MFR to ensure component authenticity and quality.

• I verify the manufacturer's name and part number against approved vendor lists.

• I check for any counterfeit or fraudulent components.

• I review the manufacturer's datasheet to ensure the component meets specifications.

• I may perform additional testing or analysis to confirm authenticity and quality.

• Examples of tools used for validation include Octop

FFT calculation resolution refers to the smallest frequency difference that can be accurately represented in the output of a Fast Fourier Transform.

• FFT calculation resolution is determined by the number of samples and the sampling rate used in the FFT algorithm.

• It is inversely proportional to the duration of the time domain signal being analyzed.

• Higher resolution can be achieved by increasing the number of samples or t...read more

Capacitor, J-FET, MOS-FET & Transformer symbols and working principles.

• Capacitor symbol: two parallel lines with a space between them. It stores electrical charge.

• J-FET symbol: a gate connected to a channel. It controls the flow of current.

• MOS-FET symbol: a gate between two channels. It amplifies or switches electronic signals.

• Transformer symbol: two coils with a core. It transfers electrical energy from one circuit to...read more
