Fiberglass-Reinforced Plastic PCB Suppliers

FR4 PCBs, or fiberglass-reinforced plastic (FR4) PCBs, are the most widely used type of circuit board in the modern electronics industry. Their core feature is the FR-4 material, a composite of epoxy resin and fiberglass cloth, as the insulating substrate. This type of PCB is distinguished by its excellent electrical insulation, high mechanical strength, and outstanding heat resistance, ensuring stable operation in a variety of environments. For example, a typical double-sided OSP PCB, made from FR-4 material from premium manufacturers like Shengyi, boasts a standard 1.6mm board thickness and a 36µm finished copper thickness, ensuring both structural stability and reliable electrical connections. The OSP (Oxidation Preservation) treatment provides a flat, highly solderable copper surface for soldered components, making it ideal for subsequent reflow soldering. Therefore, FR4 PCBs, with their balanced performance and cost-effectiveness, are widely used in a wide range of applications, including industrial control equipment, automotive electronic systems, smart home appliances, and consumer electronics, making them a classic and reliable choice for carrying circuit functions.

Why High-Tg FR4 is Essential for High-Temperature Environments: Key Differences in Thermal Reliability

Understanding Glass Transition Temperature (Tg) in PCB Substrates

In the world of printed circuit boards, the "Tg" or Glass Transition Temperature is a critical threshold. For a standard FR4 PCB, Tg represents the temperature at which the base resin changes from a rigid, "glassy" state to a more pliable, "rubbery" state. Once this temperature is exceeded, the material's mechanical and electrical properties degrade rapidly.

  • Dimensional Stability: High-Tg materials maintain their structural integrity better under heat. Standard FR4 may expand excessively in the Z-axis when heated, which can stress and break copper plated-through holes (PTH).
  • Delamination Resistance: High-Tg boards offer superior resistance to delamination during intensive soldering processes (like lead-free reflow) or in high-heat operational environments.
  • Chemical and Moisture Resistance: High-Tg resins typically exhibit lower moisture absorption and better chemical resistance, further enhancing the long-term reliability of the circuitry.

Anhui Hongxin Electronic Technology Co., Ltd., strategically located in the China PCB Industrial Park in Guangde, has recognized the growing demand for thermal reliability since 2013. With 20,000 square meters of advanced manufacturing space, our expert engineering team—featuring professionals with over 15 years of experience—specializes in the production of high-Tg boards and complex multilayer structures (up to 32 layers). We ensure that our high-performance FR4 products meet the rigorous demands of automotive, industrial, and telecommunications sectors.

Parameter Comparison: Standard FR4 vs. High-Tg FR4

The choice between standard and high-Tg materials is often driven by the operating temperature and the complexity of the assembly process. Below are the typical performance benchmarks:

Property Standard FR4 High-Tg FR4 Impact on Reliability
Tg Value (DSC) 130°C - 140°C 170°C - 180°C+ Higher heat tolerance before softening
T260 / T288 (Time to Delamination) Low to Moderate Excellent (>60 mins) Survives multiple reflow cycles without damage
CTE (Z-axis Expansion) ~3.5% - 4.2% ~2.2% - 2.8% Reduces risk of via cracking during heat cycles
Td (Decomposition Temp) ~310°C ~340°C+ Prevents carbonization of the resin
Suitable Process Lead-based soldering Lead-free / High-heat operation Required for modern RoHS compliance

Frequently Asked Questions (FAQ)

Q1: When should I choose High-Tg FR4 from Anhui Hongxin Electronic Technology Co., Ltd. instead of standard FR4?
