| Question conector cartridge and microSD contacts electrical |

It is not silver, it is likely nickel, which is used for gold plating. Then there is bare copper of the PCB track. What is your actual problem? Why do you need this information? |
| micksmelanie:
This information I want to clarify because I had these doubts about the durability and wear of the golden connectors of the snes cartridge and the SD HC and MicroSD card and the connector that receives the microSD card I'm in doubt if the insertion cycle for these 3 items is 1000, 5000 or 10000? gold contact of an sd2snes cartridge, gold contact of the SD HC and MicroSD card and the microSD gold blade connector the degradation of the Snes cartridge contacts the first layer is golden, then there is this silver layer that you say is nickel after scraping the nickel the cartridge stops working? |
| ataradov:
Why do you need to know this? If you are not sure, just assume the lowest reasonable number - 1000 or so. No, it will go down to copper and the cartridge will continue to work. In this scenario the connector in the SNES will go first. It is also rated for similar number of insertion cycles. |
| micksmelanie:
1000 is for the cartridge or the cartridge connector present in the video game or microSD and SD HC card or the card connector? on the cartridge contacts is the first layer copper? when removing copper comes nickel and after nickel? is there a problem if i keep a microSD card inserted in the connector for many years? |
| ataradov:
Any of them. This is just a reasonable number. Do you want me to tell the exact number for a board and connectors you don't have nay information about? It is impossible. And this whole discussion is pointless unless you have a really good reason. And I doubt it. All those things will survive decades of careful use. No, there are no issues in keeping the card inserted. The stack is PCB-Copper-Nickel-Gold. And you are not wearing through copper by inserting the connector. It is just not going to happen, |
