    When you say PCB at the beginning are you referring to raw PCBs or PCBAs? Presumably your service will be sourcing raw PCBs from China still and just doing PCBA?

    When my pal’s raw PCB company went out of business, you could buy a finished PCB from China for less than the cost of FR4, which also came from China. How do you intend to address this supply chain risk? Once China raises your cost of raw PCBs your price argument no longer works.

    Also, are you sourcing components from US sources or using China? Recently I stopped purchasing from Digikey and Mouser because their services are much slower than they used to be, and I now get components much faster and for lower cost in China.

      We source PCBs from both China and USA. Some of our customers want incredibly fast turn where Chinese shipping times don't cut it.

      > How do you intend to address this supply chain risk?

      Haven't yet figured it out. Options are opening bare board fabs or partnering with US fabs and panelizing orders.
