In the circuit I accidentally connected output of the amplifier to the ground. Could it damage my chips?

All components of the circuit are already on the PCB, amplifiers are powered from 3V and -3V batteries. My top layer is grounded and there is a possibility that soldering the chip we connected output to the ground layer so that at the moment of testing the circuit our output of the chip was shorten.

And one more question: during the soldering, how easy it is to damage the chip by heating the pins? How sensitive chips to the heat?

Thanks a lot.

It depends on how much current you drew when you shorted it.

Also soldering some components (IC's/Transistors mainly) can be affected by heat. Typically you want to use a heat sink (just clipping alligator clips to the pin being soldered should be enough) when soldering components like this.
 
Thank you!

About alligator clips. The pins of the chip are very small how can I connect alligator clips to them while soldering? I have traces connected to the pins on both sides of the PCB so I need to solder some pins on both side.
