Hello, Is there any standards regulating the maximum allowed solder joint temperature during operation? Is there a temperature upper limit when you come into real trouble from a solder joint reliability aspect? We are discussing a temperature around +90 degree C for a short period( one hour) perhaps three times a day, low temperature +35 to 40 degrees C.
