For those wanting to fill-out their basic understanding of flexible circuits, there's a pdf version of Joe Fjelstad's 3rd edition of "Flexible Circuit Technology" is available for download here: http://www.flexiblecircuittechnology.com/

In the design stages, we have been asked about the difficulty in soldering a 4AWG (stranded) wire to a PCB for a high current application. Questions - can this be hand soldered normally? What about wave? Process will probably be Pb-Free. All opinions

What kind of circuit board are you using that can carry the amount of current that would necessitate the use of a 4 awg wire? Cant you just terminate the cable with a ring terminal and screw or swage it into the board?

I would choose wave over hand solder. Top side wetting due to thermal mass will be your biggest obstacle. Of course I don't know the size of your soldering irons or how weak your wave may be.....

Yea wave is prob best but you still might have issues depending on the hole size in the board and if you have some kick a$$ top side preheating...

I'm curious myself. What IS the application that stuff that big would have to go through a PCB?? 3-phase, 460V?

All, Thnx for all your inputs. We have decided to use Rapid Lock sockets & pins instead of soldering the wires.

I have seen this on our assemblers look in the machine and check to be sure there is no obstruction IN the down flag sensor located on the bottom of the front transport assembly.

I do not know the QSV-1, but it sounds like there is a sensor that would detect when the clamp is open. Try to find this sensor and see if it is working.

We were told to turn on the air supply prior to turning on the power to the machine. We see this error when we forget to turn the air supply on first, you can just aknowledge the error and it will work.
