I'm more impressed by the cavity PCB construction--fill with epoxy and boom dead simple waterproofing! I've never encountered this before; wonder if it's available with the batch fabs.
- SecurityLagoon 6y agoPretty common in ruggedized devices. Has the benefit of keeping components stuck down under vibration and tamper evident too.
- jononor 6y agoThe technique is called "potting", and is common for small rugged devices. I think nearly all assembly houses will offer it. Some electronics components, such as relays, power converter modules also use it.
- mastax 6y agoThe difficult part is the step milling for the cavity. Its unusual so you need to work with the fab to get it right. Bunny Huang had a good post about it.
