What this manufacturer makes
JLCPCB combines online bare-board manufacturing, component sourcing and assembly. Its rigid-board capability page defines limits by layer count, copper weight and material. The profile below isolates impedance-controlled FR-4 multilayers, keeping material-specific and heavy-copper exceptions in the source sheet.
