content: Have any of you guys got a favourite micro USB connector that you hand solder?This one looks plausible and reasonably robust. Do you reckon I could get away without soldering under it?http://www.digikey.co.nz/product-detail/en/10118194-0001LF/609-4618-1-ND/2785382

content: Quote from: apelly on April 28, 2015, 02:01:03 pmThat looks like no problem at all, just make the pads stick a little bit out to the rear, 1.5mm should be fine.Enough solder and flux and it should wick around the pins.

content: If you mean the two pads under the connector you can omit them for a prototype. If you mean the 5 pads (5V , GND, D+, D-, ID) just make the pad of the footprint a bit longer like suggested by PeterFW.

content: Ah, I see the confusion. I meant the pads under the connector body. The pins look fine.Thanks guys.

content: I just used that exact connector in a USB li-ion battery charger project. Worked great. (Olympus cameras, annoyingly, come with a bulky AC cable and "box" charger, which adds a fair bit of weight when traveling.)I used round holes for all four pegs, and may have extended the signal pads backwards somewhat. If there were any pads below the frame, they were connected to the through-pegs, so easily hand-solderable.I have a kicad footprint if anyone's interested.

content: Quote from: apelly on April 28, 2015, 03:43:00 pmWell, I just looked and my part is a different number, FCI 10103594. What's the difference? I don't know, although yours is cheaper.Anyway, here's my kicad footprint in case it helps (maybe they're the same):http://www.keteu.org/~haunma/FCI_10103594.kicad_mod

content: I used the exact same model several times with just large enough holes for the "corner posts". They hold the socket quite well. The solder pads for the pins I made a tad further rearwards to have some space for the soldering iron. I tried to solder one with the hot air tool and you have to heat them up pretty well to the point where the plastic gets mushy. Not the best either. Now I solder the pins with hot air and the mounts with a soldering iron later.
