Julian, why don’t you post the Gerber files so that we can order your boards from JLCPCB? You make fantastic circuitry. It would be very helpful if you assisted your viewers in copying your projects.
Please this components with board rupees
What are the breakable ic socket female to dupont called?
Hi, where is exactly "matte" black option on jlc website? because I didn't see one. Or do I need to specify the color in remark column? Last time I ordered black color from jlcpcb it came with glossy finish.
If you use EasyEDA there is an option for automatic copper layer rebuilding after any change you make to the PCB. If you're still in the design phase it gets old quick but as you get closer to finalizing your design it's probably a good idea to use that option. Not often that you can get to show that mistake on a PCB so it's awesome to show everyone this mistake and how to fix it. If your traces are at like 6mil fixing it by cutting the PCB would require a microscope and steady hands (darn near impossible). Great video lesson!
JLC's matte black finish is kinda crap. It does affect soldering, just as Julian noticed. I shan't be ordering any more black from them. I recommend the red and the blue. And the green of course. The yellow is horrible.
10th of an inch?..lol…wer'e metric 🙂
Too many power supplies; unless they are being used to power something else as well as the display unit.
Julian, if you are making two boards then why not make the board with the LED's a stand alone board with just the LED's on it. Then run the traces out to the edge where you can't see the solder connections and run two rows of header pins. The daughter board can have all the electronics on it. Make it like an Arduino UNO. The LED board is your UNO and the electronics board would be like plugging in a shield. Then you eliminate all the problems you were discussing including the problem with the resin showing up and having to try and clean it off.
If you make the black boards again, just change the LED holes to non-plated one-sided pads. You can do that.
I puked at the number of times I heard matte black
why not put the rectangular LEDs side by side….instead of a gap between them
Excuse me, but did you call a slash a "stroke?"
jack you made it so whats up……..
It seems that you don´t follow any suggestions from the comments….so i think i will stop commenting….
A last one: you really should follow the datat-sheets. They aren´t there just for fun. But they should be used as a guide, on how you should design a circuit using the specific component……
Also you could easily got away using any sort of LEDs by setting the current limit using a simple resistor divider on two of the LM391x pin, which are adressing that specific problem you had with these green LEDs
And if you don´t like the green PCB color, simply go to "home-depot" buy a little spraypaint-can of black-matte and there you go….
