Responding to: ???'s previous message
Must go from Vcc to Gnd of the IC it is protecting.
Not Vcc to any ground. Moot of course with a ground plane.

How its happen?            01/01/70 00:00

   my 2 cents            01/01/70 00:00      
   What is exactly RLY fuction?            01/01/70 00:00      
      Effect of relay            01/01/70 00:00      
         Isn't it called EMI?            01/01/70 00:00      
            Sure - radiated and conducted            01/01/70 00:00      
               Ok, thought so :)            01/01/70 00:00      
                  Maybe it's a test?            01/01/70 00:00      
                     Not very kind to operator :)            01/01/70 00:00      
         A diode helps.            01/01/70 00:00      
            But immunity is best!            01/01/70 00:00

   Ok, we posted in the same minute :)            01/01/70 00:00      
      This time it was Andy and AGAIN same time :)            01/01/70 00:00      
      I'll build in some random delay next time :-)            01/01/70 00:00      
   the solution will be here            01/01/70 00:00      
   I'm puzzled            01/01/70 00:00      
      It damps out the relay voltage spikes?            01/01/70 00:00      
         not much, if any - 33pF?            01/01/70 00:00      
            Should be a printing error.            01/01/70 00:00      
   let's focus            01/01/70 00:00      
      Of course it is possible.            01/01/70 00:00      
      why focus            01/01/70 00:00      
         because......            01/01/70 00:00      
            Part more susceptable to EMI?            01/01/70 00:00      
            'experiment' all you want            01/01/70 00:00      
            prevent problems            01/01/70 00:00      
      where did we not focus?            01/01/70 00:00
