Advantages and Disadvantages of Designing a Custom PCB 

When designing an electrical or electronic system, product designers may find themselves asking “Should we be spinning a custom PCB (Printed Circuit Board), or hand-wiring on a perfboard or breadboard?” This article discusses some of the advantages and disadvantages of Designing a Custom PCB identified during a group discussion of StarFish Medical electronic engineers.

How to get the most from your FDM 3D printer

Fused Deposition Modelling (FDM) desktop 3D printers have become a huge part of prototyping and testing. Knowing how to get the most out of your 3D printer is increasingly important when designing parts. There are countless factors that influence the quality of your final printed parts, such as print temperature, layer height, and print speed. […]

How to construct a custom differential screw

Understanding a differential screw and how to construct one I recently had to construct a custom differential screw when designing a precision test fixture for one of our medical device projects.  We used it to locate a test piece within +/-0.03mm. This motion required minimal force, and each part required a set of specific locating […]

Consider these 3 areas carefully when testing medical devices in a Biolab

Keep your project on time, within budget  Testing medical devices in a Biolab often requires changing locations from an engineering lab to a Biosecurity Level 2 (BSL2) BioLab that can facilitate specialized tests involving potentially dangerous microorganisms, tissues and biological fluids. Careful pre-planning is required for timely experiments to take place in BSL2 BioLabs. Poorly […]

Temperature Measurement and the Application of NTC Thermistors 

When I say temperature sensors, you’ll likely think thermocouples. But today I’d like to discuss NTC thermistors. Medical devices regularly need to measure  temperature. Often engineers overlook or under-estimate the inherent challenges. Whether designing in thermal measurement and control capability or just temporarily instrumenting up a test rig, it’s worth thinking about how the device […]
