HMC661 IC , what is safety while Stuffing chip on PCB. It gets damaged easily, whereas it is an expensive IC

Question

I am taking care of ESD protection but IC gets damaged during soldering on PCB or reflow; don't know what is the issue as it is an expensive IC

If the IC is damaged during soldering / reflow, it's possible that this is caused by moisture inside the device rapidly expanding due to the high temperature of the reflow machine. 
 HMC661 is rated Moisture Sensitivity Level (MSL) 3, which means that the IC must be soldered or reflowed with 168 hours of opening the sealed bag. The ICs must be baked to remove moisture if the bag is open for more than 168 hours.

Hello MsKhalid, 
 Per page 10 of the HMC661 datasheet hmc661 (V03.0615) (analog.com) , ESD protection level is 1B.
