Okay, that didn't change since the last time you answered this. (You just answered the more complete version of my reply sent back on 27 Jun. I accidentally sent it before I finished writing it--and then sent the complete version after I finished writing it. You replied in June to the incomplete version of the message and today to the complete version. Sorry for causing any confusion as I am still making peace with the user interface of my smart phone E-mail client--which I'm thankfully not using right now.) >> 3.

Sounds like an improvement in manufacturability. Which part are you using? These are all mid-mount micro-HDMI receptacles. part number mounting depth Shell DIP length(mm) DC3R019JA1R1500 0.95mm 1.2 DC3R019JA5R1500 0.95mm 0.8 DC3R019JA7R1500 0.65mm 0.65 _______________________________________________ arm-netbook mailing list [email protected] http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook Send large attachments to [email protected]
