Yep as in all modern electronics , with the use of robotics they do the 95% of the process.
And I bet that the same happens too , with multimeter's - mobile phones and everything fresh made.
The bottom line are , that in this modern way of making things , all the responsibility about construction quality , falls over the solders of the companies who build those automation's.
And actually the modern Electronics engineers , do the primary plan of what they need, and the machines do the execution.
In order to be 100% honest I would say that at this point, that the responsibility for an healthy product its 50/50 ( theoretical planing / assembly ) .
And what gets from the above tail , are that if some one looks for an work in a such facility he must be specialized to service such systems .
