Wapata Posted January 6, 2019 Author Report Posted January 6, 2019 (edited) Hi ! I'm happy to say that the core is okay, i've soldered my second LCD and... it's working GREAT ! See the lasts pictures ;) https://photos.app.goo.gl/5bR4r2ivZe5dgYYW9 @TK. I've added three of them in the Gallery, please fell free to use them if you like.

Wapata Posted January 8, 2019 Author Report Posted January 8, 2019 So... It take way too much time to start using eagle. What a nightmare for a such simple board: Note that i havent check the reverse/mirror pin thing yet because I have a question first: how to make the upper solder pads to touch the border of the board ? This way it will be possible to solder this board to a 90° angle to the LCD with no wire. And then I will find how to add the ribbon connector schematic..
latigid on Posted January 8, 2019 Report Posted January 8, 2019 Maybe you can get it to a single layer by routing through the SIP header. For pads to the edge, you could consider a castellated pad/via. Normally the fab will charge extra for it. I'm not sure if it's a good idea mechanically; the simple pin header would be stronger. Or maybe I don't understand your idea.

latigid on Posted January 9, 2019 Report Posted January 9, 2019 I've done exactly this (with the board outline at the edge) at OSHPark. About half of my boards had missing copper though, as I suppose the router can pull the plating off.

Wapata Posted January 10, 2019 Author Report Posted January 10, 2019 Yes ! Theses are good tips ! I'll try by myself now with standard connectors. I have to learn and it's a useful exercise. And with the files you provided it will help too. Thanks !
Wapata Posted January 10, 2019 Author Report Posted January 10, 2019 Take a look: There was no chance that I could find it with the search function but... By looking deeper and deeper in the forum I fall into this tread.

Also, the way CMOS labels power connections as Vcc Vdd Vss etc. can also lead to mistakes. I didn't check the pin compatibility (please check!), but this PCB might help:
