So i was looking at the various usb connector types. What exactly does the enginnering process for connectors look like? How come the usb connector did not start in the micro size? Was there real unknowns about the connector manufacturing process and durability relating to physics of plating and stamping and all that stuff or was the tooling required for smaller tooling made more economical since the rise of usb? Or is it more like multitools where you can probobly make yhe latest leatherman in 1920 but it was just not specced that way for some reason? Or are there deficencies in the smaller usb connectors so it was some kind of engoneering tradeoff? |

Hi, It should be obvious why the USB connector did not started to be manufactured in the micro size. The USB standard was created to replace a multitude of connectors like the PS/2, DIN 9 and the like. If you see the size of those connectors, you can easily see that the standard A or B connectors are actually small and indeed a breakthrough. Then the mini USB came to be. It was smaller, but flawed in design. The standard between mini-A and mini-B was not clear, and the connectors didn't last, especially the female ones. In order to "solve" the mini connector "blunder", the micro USB connector was created. The micro USB is not much smaller when compared to the mini version, but it is far more reliable. Also, if you think, the standard A and B connectors are less of a technical challenge, and it is natural why they were made first, although the reason is that the mini version was not a necessity at the time, when the USB standard was first created. Kind regards, Samuel Lourenço |

Also, if you look at the state of the art in consumer technology when USB was developed, there simply wasn't any real pressure for the connectors to be any smaller. It wasn't until later on when smartphones became a big thing that there was pressure for a smaller, more reliable standard connector. |
