Nice FR4 PCB board with good quality made in Shenzhen China

FR4 is a commonly used printed circuit board (PCB) substrate material, mainly composed of fiberglass cloth and epoxy resin. Fiberglass cloth provides excellent mechanical strength, allowing PCBs to withstand certain external forces without easily deforming or damaging; Epoxy resin plays a role in bonding glass fibers and has good electrical insulation performance and chemical stability.

PCB or Printed Circuit Board is the traditional name for the bare board of which we produce with the layout data and which will be used to mount the components on.

A printed circuit board, or PCB, is used to mechanically support and electrically connect electronic components using conductive pathways, tracks or signal traces etched from copper sheets laminated onto a non-conductive substrate. Components are generally soldered onto the PCB to both electrically connect and mechanically fasten them to it.
