Hi,

I am making Industrial controllers based on Teensy 3.2 and Teensy 3.6 . So far everything works good. I design my own custom PCBs and mount the teensy on it.

My only issue is the Micro Type B USB Connector on Teensy is rather unreliable to be terminated on back panel. Right now I have to place an extension cable like this https://www.pjrc.com/store/cable_usb_panel_micro.html cable_usb_panel_micro.jpg

Is there a way I can transfer the data connections from the Teensy to my PCB and can mount a USB type B connector directly on my PCB so it will be more rugged. I already power the Teensy with External Supply.

Thanks for any help.

If you look at the back of the Teensy 3.2 pinout (https://www.pjrc.com/teensy/pinout.html), you will see 4 pads for the Teensy's USB (ground, D+, D-, power). You should be able to connect wires to those (or use pogo pins) to bring out the USB connection.

I clipped this some time ago, about a user that did something similar: https://github.com/macaba/Teensy-3.2-USB
 
WOW! That looks neat. However my Teensy PCB are mounted in middle of my board. IN the Teensy 3.6 there are few terminations D- and D+ can these be used. These will be easier to just mount a header and then use it.
Thanks a ton anyways.

Note, the D-/D+ in the Teensy 3.6 are for the second USB port, the one that the 3.6 is the USB master. It is not the USB port that powers the Teensy or provides programming support. For the Teensy 3.6, you would need to use something that mates with the D-/D+ pads underneath the Teensy, just like the 3.2.

Note, if you have any old Teensy 3.1's, they would not be able to be used, because one of the small changes between 3.1 and 3.2 was moving the USB solder pads.

As I recall, the store by Talldog in tindie.com also has a PCB that is mates with the Teensy 3.2 and brings out all of the bottom solder pads. It also uses pogo pads to bring out the USB D-/D+ and the reset pad:
