4-layer pcb
This 4-layer PCB uses FR-4 Tg135 as the base material, offering a thickness range of 1.0 to 1.6mm. The copper layer is specified as H-1oz, which is a half-ounce (17.5µm) thickness commonly used for signal layers in standard applications. The material’s Tg135 rating ensures better thermal stability for environments with elevated operating temperatures.
FR-4 Tg135 is a standard epoxy-based laminate known for its mechanical strength and electrical insulation properties. Typical dielectric constant for this grade is around 4.2 to 4.7 at 1 MHz, and its glass transition temperature of 135°C makes it suitable for lead-free soldering processes. The board is designed for high-frequency applications where signal integrity is critical.
These PCBs are supplied to industries like telecommunications, automotive, and consumer electronics, where multi-layer designs are essential for compact and reliable circuitry. The boards are manufactured to meet international quality standards and are compatible with standard assembly processes. Buyers should confirm packaging and lead time at the order stage.

Sourcing 4-layer pcb from Shenan Electronic Technology Co., Ltd. - China Import Guide
Before placing an order, confirm the exact copper thickness for each layer and verify that the Tg135 rating meets your thermal requirements. Request documentation such as material datasheets and thermal stability test reports to ensure compliance with your application needs.
Discuss packaging options, as PCBs are typically shipped in vacuum-sealed anti-static bags to prevent moisture absorption and physical damage. Clarify lead times, which can vary based on production schedules, and agree on Incoterms such as FOB or CIF for your shipment.
For quality checks, inspect the boards for delamination, copper thickness consistency, and dielectric strength. Request certificates of compliance for FR-4 Tg135 and any relevant UL or IPC standards. Ensure the supplier provides test reports for electrical continuity and insulation resistance.
