Lead-free solder pasteHow to manage during the usage process?Generally, when we use it, what exactly should we pay attention to?In this regard, let's have the professional talents from Shenzhen JJY Industrial Technology Co., Ltd. explain it to everyone: The first thing to pay attention to is the storage temperature. Different materials have different suitable temperatures. Especially for the storage environment of this paste product, it is even more necessary to pay attention. If not careful, it is easy to go bad. Once it goes bad, it cannot be used anymore.

Many people may also think that the products in industrial production are different from ordinary food and have a long storage period. Therefore, many people do not pay special attention to this phenomenon from time to time. In fact, the storage time of any lead-free solder paste is only6Within a month, it must be used up in a timely manner within the prescribed time period; otherwise, it cannot be used. So, how should we manage it when using it?

1. The production and manufacturing application staff should assess the weekly or monthly demand for heavy metal-free solder paste, conduct approximate statistical analysis, keep records for the next purchase, and make a filing when collecting solder paste(Such as the total number, the specific time and time of the material requisition date, etc)bySMTThe person in charge immediately supervised that when employees change solder paste, they must use empty solder paste bottles;It is prohibited to replace solder paste without authorization.
　　When applying solder paste, it is important to note that it must not be mixed with other types of solder paste. A series of supporting facilities and special tools, such as scrapers, must be selected. The principle of "first in, last out" must be followed when entering and leaving the warehouse. It is strictly forbidden to store the solder paste in the cold storage for too long;The solder paste suggested after opening the watch cover is12Use it up within hours. If you need to store it, please put it in a clean empty bottle and then seal it tightly and put it back in the freezer for storage;When packaging printing is suspended: If the packaging printing work needs to be suspended beyond40At the minute, it is best to scrape the solder paste on the steel wire into another empty bottle to prevent it from drying out and being consumed.
　　When applying solder paste, if necessary, use transparent tape to protect the unnecessary solder layers to prevent additional solder from causing waste. New operators should undergo onboarding learning and training. When using heavy metal-free solder paste, employees should be taught to add tin properly. It is strictly forbidden to add too much tin during spot soldering, which may lead to waste.
