content: I've been looking for a completely SMT USB type-A sockets, and found these:http://www.mouser.co.il/Search/ProductDetail.aspx?R=KUSBEX-SMT2-AS1N-BTRvirtualkey51700000virtualkey806-KUSSMT2AS1NBTRhttps://www.arrow.com/en/products/uj2-ah-1-smt-tr/cui-incThey use the same footprint, which is the same you can find on ebay like these:http://www.ebay.com/itm/100Pcs-USB-Type-A-Female-4Pin-SMT-Socket-Solder-Connectors-/181632047439Is there a name for that particular model or footprint? I'm trying to compare prices but just setting "USB type-A female SMD connector/socket" in parametric searches gives me a lot of sockets that have prongs sticking through the PCB, which I can't use (the bottom of the PCB should be flat).I have the Kycon ones, and the ones from E-bay, and the're almost exactly the same in their dimensions (except the ones from E-bay are janky and made from a ferrous metal). Would these dimensions or footprint be standardized?

content: It's not really widely used and I would suggest avoiding using it if you are designing it into a new product. Easy to knock it off the board together with pads. There is no standard name AFAIK.

content: Most surface-mount USB connectors will have small plastic nubs for alignment, but unless you're using some crazy-thin PCB the won't stick out the underside. Consider using apanel mountconnector for better mechanical durability.

content: Quote from: andersm on February 26, 2017, 06:41:08 pmYeah, the ones I'm using now have them, but those are less than a mm in length and are zero-force-insertion, so they don't require another step after the pick-and-place process.Quote from: donotdespisethesnake on February 26, 2017, 02:11:23 pmI'm looking into alternatives. Some of them have SMD leads but anchor their frame to the PCB, like this one:http://il.farnell.com/amphenol-fci/87583-2010blf/usb-2-0-type-a-receptacle-smt/dp/1314363Can those be placed by a pick-and-place machine, or do they have to be snapped in manually? I assume they require manual soldering if you want those anchors to properly bond with the PCB, but can the initial placement be done with a machine?
