KiCad PCB Affordable Manufacture
JLCPCB Manufacture no longer offers low rate DHL shipping to USA.
Slightly less expensive alternative is Elecrow PCB Manufacture.
For both of the manufacturers costs are subject to number of Gerber Files
in the submitted ZIP File. As well as other choices.
PCB Board size is a major factor in cost.
I have been using ‘Quick-Turn’ minimum 7 Gerber Files in a ZIP to keep cost down:
EDGE CUT
PTH DRILL
FRONT SILKSCREEN
FRONT SOLDERMASK
FRONT COPPER
BACK COPPER
BACK SOLDERMASK
Other PCB manufacturers are also omitting the ‘slow boat’ DHL shipping to USA.
