                Hi Jean-Francois
                That could be done for a prototype or a preprod or perhaps a class 1 board. I have done it by gluing the part to the board ( upside up ), raising the leads so that they are floating and using jumpers to pads.
                Regards,

Subject: [TN] Flipped transistor?


Here is a first for me!

Before I go ruffling some feathers I would like to have others opinion.  I've just been informed of a modification on a boards that requires to install a SOT23 NPN transistor to be fliped on its back in order to be soldered.  The poor leads are then bent backward to contact with the board's lands of some other component.

Engineering did not raise a flag on that yet... I'm worried to say the least because I'm convinced that this is a NO NO!  

Anyone has seen that in the past?

Thanks!

Jean-François
