Part:TDA8932BTW/N2,118 ，Is it normal that pins 1, 16, 17 and 32 are not connected by X-ray? Please help to give an explanation, thanks！
A pin joint is a connection between two objects that allows only relative rotation about a single axis. All translations as well as rotations about any other axis are prevented — the joint therefore has one degree of freedom (1-DOF).

Are these 1, 16, 17 and 32pins electric connected together when you test this part?
Only 1 pin is connected, 16,17,32 are not connected
Please see X-RAY picture attached.
