What should I do if the storage temperature of lead solder paste exceeds the standard?

inThere is lead solder pasteDuring the storage process, if there is a sudden power outage and the storage temperature of the solder paste exceeds the standard, what should be done at this time? Today, the solder paste manufacturer will discuss with everyone the issue of excessive storage temperature for lead solder paste.

Correct handling countermeasures for excessive storage temperature of leaded solder paste:

1In case of sudden power outage, the temperature must not be lower than25℃At the same time25℃It can be stored for a relatively long time in such an environment24HIf the connection times out, it needs to be sent to the project for evaluation. Only after the analysis and evaluation are qualified can it be carried out. Otherwise, scrap it.

2In case of a sudden power outage24HThe amount of solder paste taken from the refrigerator should not be less than used up48H. Otherwise, scrap it.

3If the temperature is greater than10℃Less than15℃To be72HWhen the internal usage is exhausted and the connection times out, it needs to be sent to the project for evaluation. Only after the analysis and evaluation are qualified can it be carried out. Otherwise, scrap it.

4Fill in the sudden power outage situation in the "Refrigerator Power Outage Record Form".

5,.Under normal circumstances, if an alarm signal occurs due to the temperature exceeding the specification, it should be based onPDCSProcess handling.Except for the regular inbound and outbound of solder paste

6Production and processing of each2Conduct an inspection every hour and record the data in the inspection form.IPQCDo a good job in auditing.

Only by doing all these can we use lead solder paste more reasonably when the storage temperature exceeds the standard and reduce the waste of solder paste. Under normal circumstances, the storage temperature of solder paste is0-10℃At the same time, maintain a sealed state to prevent the solder paste from oxidizing and affecting the quality. In addition, scrapped solder paste should be properly disposed of separately and must not be placed together with normal solder paste.
