I'm thinking about replacing a USB 3 Micro-B receptacle (the wide boi, who ever thought of that garbage, srsly), on a board I'd like not to redesign from scratch, with an adapter board to a USB-C receptacle (that I would design). The device only requires USB 2.0 connectivity, thankfully (it's a keyboard, thanks for asking).

The existing connector footprint has 0.65mm pitch, 0.4mm wide SMT pads. I'm guessing castellation will be impractical at such small sizes (and hobby budget) and I'm thinking of using gold fingers on a Flex PCB, to solder across, instead.

I'm coming up short on finding similar designs, even though "Flex PCB soldered on top of existing board" seems to be a common pattern of the console modding community.

Any fedi #Electronics or #Modding experts have resources on #FlexPCB design gotchas?

So I have had an insane idea for a long time but the existence of Kailh PG1316S suddenly made it closer to possible. I would unfortunately take me way out of my comfort zone…

Really frustrating when companies don't put the 5.1k usb c resistor on the connector. Devices that can't be charged using a USB C to USB C cables are not USB C comparable. Just received a really nice Mp3 player (don't ask) and it doesn't have resistors... Lucky for me I have a solution. I remixed these tiny flex PCB's that will let you add the resistor easily facelesstech.wordpress.com/202

Getting to be friends (and collaborators) with super talented makers has some nice bonus benefits! In addition to the gorgeous Fibonacci heart pendant, @jasoncoon sent me a flexible PCB he designed and assembled (!) that has 128 tiny addressable LEDs laid out in a Fibonacci pattern, along with the vector file to cut out a faux leather cover. The whole assembly looks truly stunning in cuff bracelet form.

Sent off my first to nervous and excited - it could be an interesting ... or it could all go wrong 😨 either way, it was fun - any will be happily received, as I'm hoping to make more!

Sticker Brings the Heat

[Carl] is always looking at making heater plates for PCB reflow and other applications. In his latest video, he shows how he is using thin flexible PCBs with adhesive backs as stickers that get hot. You can find gerber files and design files on GitHub.

You might think that this is a pretty simple thing to do with a flex PCB, but it turns out while the PCB might be flexible, the traces aren't and so the typical long traces you see in a heater won't allow the sticker to bend, which is a problem if you want to wrap it around, say, a coffee mug.

The answer was to create a pattern where the traces change direction frequently, and that's what [Carl] did. He also talks about using stiffeners around the edges of the board.

The video shows quite a few tests that indicate the substrate discolor after a long time with high heat. The adhesive also tends to melt in those conditions. So the recommendation is to use them where you need lower temperatures for a long time or higher temperatures for a short duration. Of course, depending on your application, the color change may not matter as long as it doesn't affect the long-term reliability.

What would you do with a flexible heated sticker? The self-warming mug is a no-brainer. A sticker to put on exposed pipes for a cold day comes to mind. A thin 3D printer bed heater or an irregular-shaped reptile habitat might be useful, too.

As long as you are putting patterns in any way, we wondered about making thermal digits on a sticker like this. It seems like every time we check in on [Carl] he's heating up something.
