A Deep Dive into Component Engineering!

kiranmr69

Welcome to the Component Engineering Thread, where we will embark on a journey through the intricate landscape of component engineering.

As a seasoned component engineering specialist based in Bangalore, India, I am thrilled to share my expertise and insights into this fascinating field.

What is component engineering?

Component engineering is the art and science of navigating the vast universe of electronic components. It involves understanding the nuances of selecting the right components, optimizing for Design for Manufacturability (DFM), and ensuring Design for Excellence (DFX) principles are seamlessly integrated into the design process.

What to expect in this thread?

Explore the intricacies of choosing the right components for your project. From resistors to microcontrollers, we'll dissect the key factors that influence decision-making and share practical tips for optimal selection of components and replacement parts.

Why do your inputs matter?

This thread is not a one-way street. I invite you, the element14 community member, to engage, question, and contribute. Your experiences, queries, and insights will enrich the collective knowledge of our community. Together, we'll build a space where learning is collaborative and curiosity is celebrated.

Are there any specific topics of interest?

I am excited to see specific topics that spark your interest in the world of components and to explore them together in future posts. Let's navigate the world of electronic components collaboratively.

    For single source components you might also note the manufacturer's "support until" date, when they may declare it to be obsolete.

    I retired about 15 years ago, so my knowledge of components is probably slightly lacking. My job title at that time was 'Senior Electronics Design Engineer', I was never quite sure whether the 'Senior' part referred to my age or my competence as a Design Engineer. The BOM suggests that my design processes and the number of people involved might well be different now too. So I apologise for anything that might seem a little old-fashioned, maybe even laughable in the following...

    Final selection of components was usually carried out by the designer(s) after extensive tests using Veroboard prototypes. Tests were for functionality (did the design do the job?), operation at both high and low temperatures as specified by the customer, 'digital drifting' of outputs despite rock-steady inputs, and, sometimes most importantly, EMC (electromagnetic compatibility) amongst others. We found that a digital circuit with digital inputs and outputs could drift both up and down...

    If I were still doing that sort of thing today I would have to wonder if SBC's such as Raspberry Pi's and Arduino's could be classed as components, and if not why not? And as far as the BOM is concerned, we havn't even looked at environmental influences such as IP ratings, vibration testing, the speed of a British Standard raindrop, etc.

    All these things and more suggest that the Components Engineer must work as a member of a team, and that the BOM needs to contain much more information than the one shown. But - I'm old and nearly grey, it looks as if things have changed since the days when two wires and a limit switch were regarded as hi-tech.

    I don't think any of that has changed, as you say, there's so much more that would be done before using a component.

    At one workplace we had ~ 300 pages of just "guidelines", which referred off to separate documents for the detail.
