One Page Guide: Is a fixed quote reasonable for electronics product development?

  What’s the issue? The essential truth is that a reasonable, firm and fixed quote for electronics product development is only possible if a complete and prescriptive specification of requirements is available. Fixed quotes are only valid if a fixed and prescriptive specification of requirements exists: try testing your specifications against our Specification Requirements article. […]

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: Operations Journey (prototype to manufacture)

  What’s the issue? As is common knowledge but often overlooked, a finalised fully functional prototype in itself is not necessarily ready for volume manufacture. Usually there is a lot of work to be done beyond this stage. This article covers this with the assumption that final prototype stage has genuinely been reached, i.e., the […]

One Page Guide: Electronic Product Development Cost

  What’s the issue? The cost of developing a product ready for market must be budgeted. Clients don’t want development on an open budget, but so many variables come into play that it isn’t prudent for any developer to give fixed budget guarantees – especially if Engineering Specifications aren’t complete. That said, there are measures and […]
