OSHPArk and PCBWay will hold your design and let other people buy them (if you wish). This is an excellent way to do cheap on-demand distribution. I don't believe Jlcpcb offer this. On Sun, Sep 3, 2023 at 10:32 PM Adrian Godwin wrote: > I had a couple of boards from OSHPark. They seemed a bit

I had a couple of boards from OSHPark. They seemed a bit slower : it took them longer to accumulate enough board orders to fill their panel needs. For a very small board (same size as an HPIB connector) they were excellent. Cheap, and postage included whereas the Chinese suppliers have expensive
