class JLCPCBVias[source]#

Various via definitions provided by JLCPCB. By default when using one of the substrates in this package, all vias will be available for use, be aware that some may incur an extra cost.

The StdViaPreferred and StdViaTentedFilled vias are options for all boards, and as of 10/23/2024 do not have any up-charge for processing.
