Hi Friends

i did an heater to hot my pcb board to welding.

 

25° C to 110 ° C is spend 60 seconds and an power off all heater.

 

But i am protect atmel 168 AU to not hot, and protect capacitor 25c 47uf.

 

My question is, with it temper 110°c, need protect capacitor and atmel, or i can hot all board.

 

It heater is lamp infrared up... more or less 10 centmeters tall.

 

thanks

 

Eder
