One Page Guide: Designing ultrasonic flow metering systems

  What’s the issue? There are two types of flow measurement with which the EM has extensive experience: gas for anaesthesia systems; water in pipes and mains. Commercial and domestic meters must sometimes be developed to measure these flows. This article examines the rules and challenges encountered in developing such systems.  How is flow measured? […]

One Page Guide: Electronics in enclosure heat: rules of thumb

 What’s the issue? Different Thermal modelling software abounds these days, but it is often very helpful to have simple calculations to hand that indicate whether or not heat will be a factor in the design of electronics. This article presents some very simple formulas from which it may ascertained whether convection (natural or otherwise) will […]

One Page Guide: Managing interface between electronics and product design

 What’s the issue? Different resources have different traits, and few could contrast more than product designers and engineers. Both have critical attributes that ease the development of a product, but if the differences aren’t appreciated conflict rather than cooperation can result.  This article covers the strengths, weaknesses and complements of the two types of resource. […]

One Page Guide: Relationship management within the Development Team

 What’s the issue? Relationship management in Electronics Product Development is critical. It is an incredibly fractious union because all concerned know there are risks and even a whiff of an entity not acting in the best interests of another can disrupt the dynamics of a team. Trust is critical. The four parties usually involved are […]

One Page Guide: Does reverse engineering electronics make sense?

  What’s the issue? Many electronics product developers find themselves with an electronic product (PCBA – assembled printed circuit board) for which they have limited or no support documentation, and they wish to manufacture and/or evolve its design somewhere other than where it was originally developed. This unfortunate predicament usually comes about because of a  […]

One Page Guide: Choosing Enclosures for Electronics

  What’s the issue? There is rarely a requirement for electronics with no enclosure, but the choice of materials, types, and performances must be properly linked to client needs. The scope can vary from a bespoke and complex form of enclosure with demanding engineering requirements to one that can be supplied off the shelf – […]

One Page Guide: Design criteria for PCB capacitive touch pad or button

  What’s the issue? It is sometimes necessary to implement a capacitive pad on a PCB. There are some very basic rules to clarify the design route – miss them and life can get painful. What follows is only semi-rigorous, but it does give the right rules of thumb for error avoidance. How do I […]

One Page Guide: Electronics Machine Development Capabilities

  What’s the issue? Because the topics of product development and sustaining engineering are so detailed and complex, it is often difficult for a client to easily work out what capabilities (design and service) a company has. This article has been written to cover this item for the Electronics Machine. What are the overall offerings […]

Battery selection

What is this all about? The choice of the right battery type and capacity is usually fundamental to an electronics design project. Quick learn Unless the company intending to use the battery is multi-national and intending to use tens of thousands of them, the electronics product designer is constrained by what can be purchased ‘off the […]

Flow/Pressure Metrics

The need for pressure or flow monitoring bridges may industries. This article covers some of the basics in the medical, general industrial, and water supply industries. The fundamentals of pressure and fluid flow don’t really change across the industries. It is necessary to do one of the following: Simply measure pressure because that what’s needed, […]
