Does anyone have experience getting plated through slots made at the low-cost China producers? I am specifically interested in JLCPCB and PCBWay requirements, but presumably experience at Seeed and others would be applicable. I have contacted both JLCPCB and PCBWay. Only one has responded, but it was vague.
I am familiar with the requirements of OSHpark, and apparently JLCPCB and PCBWay are different.
It is said that all one needs is copper on both sides of the slot. That restricts some of what you can do with the Dimension layer. One issue may be the default settings for Gerbers by Eagle pre-8 which put board outline, milling and top copper in the same Gerber ("cmp") rather than separating the board physical design into Gerber "GKO" or similar.

PS: I tried a couple of on-line viewers. One did not show slots and couldn't do drill or milling files. The other ( https://www.gerber-viewer.com/ )has a sign-on problem and cannot be contacted.
