The heart of an electromagnetic heater is the IGBT module, which acts as the control center, similar to the human heart. Biyuanda Technology uses high-quality Infineon modules, ensuring top-tier performance and reliability. We prioritize quality over cost, guaranteeing long-term stability and efficiency for our customers.
Electromagnetic heaters are widely used in various industries, but when purchasing, it's essential to focus on more than just price. Your main goal should be to invest in a reliable solution that saves time and effort, not causes additional problems. Shenzhen Biyuanda Technology Co., Ltd. is a licensed company with excellent product quality, competitive pricing, and professional on-site installation services. We welcome you to visit our facility and experience our commitment firsthand.
The IGBT is the core component of the electromagnetic heater, acting as the central controller. Infineon IGBTs are globally recognized as the premium choice, imported directly from Germany. Many suppliers use counterfeit or low-quality alternatives to cut costs. At first, the difference may not be obvious, but over time, the inferior quality becomes evident. Original Infineon modules offer superior durability and performance. Biyuanda Technology never compromises on quality; we only use genuine German-made Infineon modules in all our products.
So, how can you tell if an Infineon module is genuine? If the module burns out quickly, it might be fake. A few hundred dollars can make a big difference. Here’s how to identify real vs. fake:
**Tools needed:** Pointer multimeter, capacitance meter, magnifying glass, water, and pressure gauge.
**Step 1: Visual inspection**
1. Check the laser code on the module—real ones have clear, sharp fonts.
2. Feel the font with your fingers—genuine modules have a slight texture, similar to RMB.
3. Use a magnifying glass to check for polishing marks—real modules are not polished.
4. Examine the nozzle for burrs or sharp edges—genuine modules have smooth, rounded nozzles.
5. Check the weight—genuine modules are heavier.
6. Look at the mounting holes for signs of screws or solder—genuine modules show no such traces.
7. Press the middle square (Infineon logo)—genuine modules have unaltered silicone gel, no black spots.
8. Peel the label and check the laser code inside—it should match the label.
9. Observe the nut color—genuine nuts are copper-plated, not zinc-plated.
10. Check for a square in the center—Infineon modules have one, and the silicone gel inside should be transparent. Fakes tend to look cloudy.
**Step 2: Scientific testing**
1. Use a pointer multimeter (with a 9V battery) to test triggering—genuine modules can be turned on and off.
2. Measure the junction capacitance with a capacitance meter—Infineon FF300R12KS4 should read around 26nF. Incorrect values indicate a fake.
3. Test the withstand voltage with a pressure gauge—genuine modules can handle up to 1600Vdc, while fakes may fail.
4. Check the silk screen printing—genuine modules resist peeling even after exposure to water.
**Step 3: Additional tips**
- Always use a pointer multimeter, not a digital one.
- Avoid testing the same module multiple times to prevent damage.
- Do not touch the trigger pole directly—static electricity can harm the module.
- It’s recommended to add a parallel absorption capacitor to protect the IGBT from voltage spikes caused by stray inductance.
After reading this, you now have a better understanding of how to identify authentic Infineon IGBT modules. We invite you to inspect our electromagnetic heaters and experience the difference in quality.
