4 Layer PCB

4 layer PCB manufacturing for compact and reliable products.

YBCPCB supports 4 layer FR4 PCB fabrication for designs that need better routing density, ground planes and power distribution than two-layer boards.

Product introduction

A 4 layer PCB is a common step up from double sided designs, often using signal layers with internal power and ground planes. It can improve routing quality, EMI behavior and product reliability.

  • Good for embedded systems, wireless modules and compact controllers.
  • Stackup review helps confirm thickness, material and copper balance.
  • Suitable for prototype validation and OEM production orders.
