In PCBA processing we often found that when shipment the function index of PCBA plate is normal, but after a relatively short time, it will be a variety of adverse circumstances. So PCBA products doing aging test is necessary. There has 3 standards to test PCB Assembly aging, according to it, general problems can be found.
1.Low temperature work: place the control board at -10±3℃ temperature for 1 hour. In this condition, should be rated load. In condition of 187V and 253V, procedures operated and should be correct.
2.High temperature work: place the control board at 80±3℃ temperature for 1 hour, in this condition with load, 187V and 253V conditions, all procedures operate and should be correct.
3.High temperature and humidity work: the control panel at temperature 65+3 degrees, humidity 90-95% conditions for 48h, with rated load power running procedures and should be correct.
