However, if you're going through a prototype PCB house (Sierra Proto Express, Advanced Circuits, or any of the 100 others), they panelize it and you just get the PCB so none of these tricks work.
I would hope that if you were submitting your own panel that the board shop would treat it as a single board. I have no doubt that the board shop would further panelize the panel anyway. You just have to be able to persuade your layout tool to allow you to mix boards on the panel- it is then simply one PCB.
Also the test techniques described are actually on production panels.
I do hope that if you need them you can get the tips to work for you.
Good ideas, if you're paying for whole panels. However, if you're going through a prototype PCB house (Sierra Proto Express, Advanced Circuits, or any of the 100 others), they panelize it and you just get the PCB so none of these tricks work.
We love proto PCBs houses, because we can just buy what we need (or as many we we can get for the same price as what we need -- proto PCBs are like sheet metal parts: for small volumes the cost is all in the setup, so the cost difference between say buying 1 or buying 10 is minor), instead of ending up with a large volume of unused boards, which always happened in the past (when we had to buy ~100 boards).
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
