David, I'm curious how they size PTH's. I've been burned in the past trying new suppliers on a job, only to find their approach and my expectation differ and I get useless boards.

For a hole shown as say 32 thou, some fabs drill 32 thou (or their nearest 0.1mm size up) and then plate down, so the final hole is almost invariably less than

32 thou. Others allow for the plating build and oversize the hole accordingly.

Their chineselish KB/FAQ at

says: "What are your standard hole sizes? Are they finished size (after plate) or drill size (before plate)? Our standard drill tooling size is from 0.5mm to 6mm with 0.1mm step increase, we have no extra cost for more drill tooling. You could indicate hole size with finished size (after plate) that we will consider plating and select proper drill size"

Have you worked out what they *actually* do?
