Questions & Answers
1. What are your payment terms?
T/T, Paypal, Western union, L/C, ESROW
2. What are the types of the wiper system PCB?
The wiper system PCB mainly comprises standard control PCBs and smart PCBs. The former one controls the basic motor functions like speed and timing, and the latter one integrates rain sensors, load monitoring, and other functions to offer advanced performance.
3. Why is FR-4 (High Tg) the preferred base material?
FR4 high Tg is excellent in its thermal stability, mechanical strength, and cost-effectiveness, which are all critical in automotive manufacturing. Resistant to high heat, temperature fluctuation, and structural integrity, FR4 is feasible for wiper systems that operate near the hood and heat-generating components.
4. How is the PCB protected from moisture and vibration?
We utilize those methods to protect PCBs from moisture and vibration: conformal coating, sealed enclosures, mechanical dampening structures, potting, and reinforcing housing.
5. How does a rain-sensing wiper PCB work?
The rain-sensing wiper PCB receives input from the optical rain sensor on the windshield, and processes the signal to activate the wipers accordingly to achieve automatic wiping. The sensor also adjusts wiping speed and frequency based on rainfall intensity, improving convenience and safety.
6. Why do some wiper PCBs need conformal coating?
The conformal coating is to protect PCBs from the influence of moisture, temperature swings, dust, and corrosion. By protecting sensitive components, it can effectively prevent short circuits and prolong PCBs’ lifespans.
7. Why is ENIG (Gold plating) preferred over HASL for surface finish?
In the automotive wiper system, ENIG is preferred over HASL because it features with flat surface with outstanding corrosion resistance and longer shelf life. HASL has an uneven surface and less resistance to oxidation, making it less suitable for durability and precision requirements.
