A clean pan and new paste should wet the pad great. as the solder paste ages then it does not wet so good. I go up market and use 22swg TC wire to put it down. SMD legs i find a bit hard to cut off. 😃
Hi Dustin, 2 question because I am handeling the same usb c plug (for the first time usb c for me) at the moment. So do you have to connect the 2 vcc pins on the connector or are they connected in the Plug on the pcb? I think you have toconnect them yourself, because there are 2 for the 2 orientations of the plug you put in the connector , right? And what do you do with the B5 Pin which is going to your R3 , and A5 which is connected to your R2. I think these are the CC Pins and they have to do with the orientation of the plug, as well.. But I dont understand what you have to do with these. Think Pullup oder Pulldown, but could find.
Hi Oliver... each orientation has it's own pins. To that is why there are two of everything. (GND, VCC, etc.) The CC pins are basically used to manage the source-sink connection between USB C devices. Specifically when it comes to power delivery. In our case, if it is just for USB 2.0 and power, best practice is to pull it down with a 5.1K resistor for "legacy mode" :)
Why the flux? If your solderpaste is still within its working life it will have the right amount of flux. Would love to know who started this ( you need flux) on TH-cam! I've worked in the electronics industry since 1976 and the only time flux was used was when tining wires with a solder pot! Maybe the rework stations has a little, but it would have been banned on production. Still looking forward to part II.
I use the flux to make it easier to "drizzle". It is not because the paste is not good anymore. Just the paste is fine. It is just to make it easier to apply without a stencil or a solderpaste dispenser.
Flux is our friend ! I get the stuff everywhere but I know what you mean about 'production areas' I have also worked in environments where its use was forbidden....cheers.
Nice, I too 'wet' the paste with a bit of flux just to make it easyer to work with when using the old diode leg application technique !....cheers.

It is easy to overdo the amount of paste, this helps a lot.

@@DustinWatts thanks for that fast answer. :-) yes so its just USB 2.0 stuff or power only😁 thank you very much. Your videos are helping so much👍👍👍
@@ollidecker Good to hear Oliver! Good luck with your board design! :)
Damn these QFNs.. I just ordered some boards and worst part on it is a USB C connector. Lets see how well it works out
what a cliffhanger ;)
Haha!
No such thing as "Too Much Flux!"
There is only enough or way too much ;)

Some rather shaky hands, do you have hangover? Else maybe get it checked out;
