someone told me that if i keep the microSD card inserted in the connector for many years will this connector lose contact pressure of the blades? that's true? the golden contacts of the cartridge and the microSD card are in the sequence first copper, then nickel and lastly the exposed golden layer? joining the 3 layers what is the insertion cycle? |

Don't worry about it. --- Quote from: micksmelanie on June 27, 2020, 11:31:40 pm ---the golden contacts of the cartridge and the microSD card are in the sequence first copper, then nickel and lastly the exposed golden layer? joining the 3 layers what is the insertion cycle? --- End quote --- Until copper physically wear out. Probably 100000+ cycles. |

how to explain that a microSD card inserted in the connector will not cause the connector to lose pressure and its contact blades to wear out due to the fact that the card is pressing?is best remove card long time storage? 100000 cycles for copper-nickel-gold are they present in the contacts of all sd and microsd cartridges and cards? |

Spring metal used in the contacts is used in a lot of other permanent contact applications. It is the same metal used in the regular connectors. It will not lose springiness. Again, it is one of those things that seems to make sense, but don't in reality. But if you are paranoid, then remove the cards. I have no idea. You are asking very esoteric and generic questions. How would I (or anyone else for that matter) know how ALL the cards in the world are made. You are worrying about stuff not worth worrying about. |

The microSD connector I am referring to is this, see that it has golden sheets when the microSD card is inserted. These sheets are forced to come into contact, but if the microSD card remains inserted for a long time, do these sheets remain strong without losing contact pressure? was an electronic technician friend who gave me this information but I wanted to find out the truth https://www.electro-tech-online.com/attachments/50-pcs-8pin-conector-slot-para-cart-o-micro-sd-smd-4-p-s-fixos-cart-jpg.125639/ why some SD HC connector for me to pull the card before it is necessary to push down to unlock and the card comes out of the connector? |
