Manufacturing capability
Production includes inner layer processing, lamination, drilling, plating, imaging, solder mask and final electrical test.
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.
| Specification | Typical options | Notes |
|---|---|---|
| Stackup | 4 layer FR4 stackups | Provide impedance needs when applicable |
| Material | FR4 or high Tg FR4 | Chosen by thermal and reliability demands |
| Surface finish | HASL lead-free, ENIG | Matched to assembly process |
| Order type | Prototype, quick turn, low volume and OEM | Quantity and lead time affect planning |
Application examples
IoT devices, signal modules, industrial control boards, power management boards and compact consumer electronics.
