1. What materials are typically used for backplane connector contacts?
Contacts are often made from high-conductivity materials such as copper alloys and are typically plated with gold, silver, or tin for improved conductivity and durability.
-
2. What factors affect the performance of backplane connector contacts?
Key factors include contact material, plating, contact geometry, insertion force, and environmental conditions like temperature and humidity.
-
3. What is the purpose of gold plating on backplane connector contacts?
Gold plating enhances corrosion resistance and provides a low-resistance, reliable electrical connection over time, especially in high-frequency applications.
-
4. What is the current-carrying capacity of backplane connector contacts?
Current-carrying capacity varies by design but typically ranges from a few milliamperes for signal contacts to several amperes for power contacts.
