Electrical Contacts Gold Plated have several really unique properties that allow for their frequent use:
1-No corrosion at all, produces no patina;
2-Gold Plated Contacts can be touched with bare hands;
3-Reliable in humid environments (household, automotive, marine);
4-Gold is the least likely metal to oxidize. From this table, it can be shown that Gold's electro-potential value is -1.1, meaning it should not oxidize at all, even in water.this is the primary reason that some electrical contacts are gold plated;
5-Gold is an extremely conductive material, one of the best known;
6-Gold Plating Copper Rivet is very malleable, it is very easy to get a thin sheet of it;
Gold Flash Plating Contacts is a method of depositing a thin layer of gold onto the surface of another metal, most often copper or silver (to make silver-gilt), by chemical or electrochemical plating. This article covers plating methods used in the modern electronics industry; for more traditional methods, often used for much larger objects, see gilding.
The electrical contact performance between the contacts in a miniature relay or a signal relay is the key to determining its stable and reliable operation. The Gold Plated Contacts resistance in-situ test and analysis system is used to test the contact resistance curve of the gold-plated contacts at a contact pressure of 0-100 mN. According to the relationship between Au Plated Contacts resistance and contact pressure Rc=KcF-m, the Gold Plated Electrical Contacts process is divided into an unstable contact phase, a slightly convex monomer contact phase, a transition contact phase and a stable contact phase. Further, the rough surface is more convex The body contact model explains the jitter-down phenomenon of contact resistance in the transitional contact phase.
Why are some electrical contacts gold plated?
Gold is really expensive. Why then would anyone bother to plate silver contacts with gold? Does it have some unique electrical characteristics that make it useful? Gold Plated Relay Contacts provide reliable switching when the wetting current is low, because there is no oxide to breach for electrical contact to occur. Ex: a pushbutton switch used to signal a microcontroller digital input has a pullup resistor sized to flow 50 uA when the switch is closed. A switch without gold plating might not be reliable.
The Advantages of Using Gold-Plated Electrical Contacts:
Gold is an expensive material that increases the cost of the manufacturing process, so why it is so frequently used to plate electrical contacts? Gold contains numerous unique properties that can enhance the finish and improve the quality of the workpiece. Many manufacturers discover that the additional cost of gold plating is offset by the benefits derived, resulting in a solid long-term return on investment.
