inThere is lead solder pasteDuring the storage process, if there is a power outage, causing the storage temperature of the solder paste to exceed 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-containing solder paste:

Countermeasures for dealing with excessive storage temperature of lead solder paste:

1In case of power outage, the temperature must not exceed25℃And in25℃It can be stored in an environment with a maximum capacity of24HIf the time limit is exceeded, it needs to be sent to the project for assessment. Only after passing the assessment can it be used. Otherwise, it will be scrapped.

2If there is a power outage24HThe solder paste taken out of the refrigerator should not be used up until it is exhausted48H. Otherwise, it will be scrapped.

3If the temperature is greater than10℃Less than15℃To be72HAfter use, if the time limit is exceeded, it needs to be sent to the project for assessment. Only after passing the assessment can it be used. Otherwise, it will be scrapped.

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

5Under normal circumstances, if the temperature exceeds the specification and an alarm is triggered, it is based onPDCSProcess handling.Except for the normal inflow and outflow of solder paste

6Manufacture every2Conduct an inspection every hour and record the results in the inspection form.IPQCConduct an audit.

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, it is necessary to maintain a sealed state to prevent the solder paste from oxidizing and affecting its quality. In addition, scrapped solder paste should be treated separately and not be placed together with normal solder paste.

The above is some small knowledge about the excessive storage temperature of lead solder paste. I hope it can be helpful to you.
