FR4 PCB, RF PCB, FPC, LED PCB
Longjiang Circuits Co., Ltd. manufactures a range of printed circuit boards including FR4, RF, flexible printed circuits (FPC) and LED‑specific boards. Their catalogue covers rigid PCBs with layer counts from one up to twenty‑eight, as well as rigid‑flex and aluminium substrate variants. Production is performed in Shenzhen, China, using standard industry processes. The company states that it has supplied boards to customers in Europe and North America for several years.
FR4 boards are built on a glass‑reinforced epoxy laminate that typically offers a dielectric constant of 4.5 and a loss tangent around 0.02 at 1 MHz. RF boards often use low‑loss materials such as PTFE or prepreg laminates, while LED PCBs may incorporate aluminium cores for improved heat dissipation. Typical copper thickness for these products is 35 µm (1 oz) with optional 70 µm (2 oz) for higher current applications. Standard industry tolerances include a minimum trace width of 4 mil and a spacing of 4 mil.
These boards are commonly used in telecommunications equipment, automotive electronics and consumer lighting modules, where OEMs and contract manufacturers seek reliable performance. Buyers should request detailed Gerber files, stack‑up information and any required surface‑finish specifications before placing an order. Trade terms, minimum order quantities and delivery schedules are not listed in the public data and must be confirmed directly with Longjiang Circuits.

Sourcing FR4 PCB, RF PCB, FPC, LED PCB from Longjiang Circuits Co., Ltd. - China Import Guide
Before placing an order, importers should verify the exact PCB stack‑up, material grades and any surface‑finish preferences with Longjiang Circuits. Request a full data sheet, material safety data sheet and, if possible, a sample panel to confirm dimensional accuracy and electrical performance. Clarify whether the supplier holds any industry certifications such as ISO 9001 or IPC‑A‑610, as this information is not disclosed in the public profile.
Logistics arrangements need careful confirmation. Ask the supplier which Incoterms they support, typical lead times for the chosen layer count and material, and whether they can ship panels in standard 600 mm × 400 mm trays. Payment terms are not stated, so discuss options such as T/T in advance, letter of credit or escrow to align with your risk tolerance. Shipping from Shenzhen may involve port handling at Yantian or Shenzhen ports, so coordinate with your freight forwarder accordingly.
Quality assurance should include pre‑shipment inspection and third‑party testing. Arrange for a qualified inspection agency to verify trace width, copper thickness, dielectric constant and surface‑finish conformity against your specifications. Request test reports for electrical performance, thermal cycling and solderability before release. Ensure that the supplier provides a full set of documentation, including the final Gerber files, test certificates and a compliance declaration for RoHS or other applicable standards.
