It was just to show the type No idea about the quality. banggood and the likes did not exist 40-odd years ago
Mostly, despite the bewildering feature set, [EAGLE] made sense.
The only thing that is puzzling me now is that this board has no holes :-)Where the holes should be, are just little golden squares in the tDocu layer.What am I not understanding?
"how do I add a size 4 mounting hole?"I have discovered how to select the Holes layer and how to create 4 holes, and also found that I can modify Properties of Holes like position and diameter... but now I'm struggling with drill sizes. If I just specify an inch size (like 1/8), will a PCB fab shop accept that?
I keep getting the "nega" (circle with a slash through it) symbol for my mounting hole, and am not sure whether this means it would not be drilled by the fab shop, or just means I've chosen a size not on Eagle's very limited drill menu.
Eagle CAD [based on JLPCB instructions] generated two folders, one called DrillFiles containing a solitary xln file and .. GerberFiles. I had difficulty getting JLCPCB's previewer to visualise the holes -- tried putting the xnl file inside the Gerber folder and then zipping, etc, but couldn't quite figure out what I was supposed to do with it. In the end I zipped both dirs (GerberFiles and DrillFiles) into one zipfile and uploaded that, hoping they can sort it out.
Watching their instruction video for the third time I saw that I missed a step: it appears that I have to add Vias manually (darnit).
I got close to fabbing a board from your ULP but the fab shop (I tried JLCPCB) rejected my file with the cryptic note Hi， there is only holes in the board and you select surface finish with HASL. The tin will connect together to cause the short circuit.Please select ENIG if you need to do the board,thanks~
I think I've discovered that a board with tightly packed Vias isn't a good candidate for the HASL process

is it also from your ULP?
if you could somehow make available your modified version of my original brd file
