Nowadays, many electronics factories complain that the overall cost of using Solder Paste is too high. As professional SMT (surface mount technology) manufacturers, they want to reduce the overall SMT Soldering cost. In normal use of lead-free solder paste, even a small bottle may look unremarkable, yet the price is very high’a single bottle costs several hundred yuan, which seems outrageously expensive. When choosing soldering products, we, as a professional lead-free Solder Paste Manufacturer, hope customers can meet their needs at the lowest cost. However, under current market conditions, a low price often means questionable quality. If SMT manufacturers want to reduce the overall cost of lead-free solder paste, they must weigh multiple factors. Below is an explanation from the solder paste manufacturer:

Reducing the overall cost of solder paste can start from the following aspects.

1. Choose the right solder paste brand.

Although solder paste is not necessarily better the more expensive it is, a high price is there for a reason. For electronics factories, choosing the most cost-effective solder paste is a difficult problem. When choosing, do not blindly pursue low-priced lead-free solder paste. The purpose of solder paste is soldering; as long as it meets soldering quality requirements while also taking cost and market demand into account, it is a sound choice. When choosing a solder paste brand, carefully consider: soldering quality, cost requirements, and the service standards of the lead-free solder paste manufacturer.

2. Save on usage.

Whenever solder paste is used, some waste is inevitable in SMT soldering. Our suggestion is to run SMT machines as economically as possible and reduce unnecessary waste. By streamlining the soldering workflow and upgrading the SMT process, lead-free solder paste wasted during printing can be collected and reused, which reduces overall cost to some extent. Precise control of solder joint positions can be achieved by upgrading the soldering process, which greatly reduces omissions and may save solder paste usage.

3. Combine old and new paste.

It is undeniable that newly purchased Solder paste solders well, as determined by the manufacturer's production process. Over time, the Flux and other components in lead-free solder paste undergo trace chemical reactions during storage, which is precisely why SMT (surface mount technology) manufacturers must store solder paste at low temperature after it leaves the factory. The flux composition in new and old paste may differ slightly due to these reactions. When conditions permit, we suggest that SMT manufacturers not discard old solder paste at will; instead, combining new and old paste can also reduce the overall cost of solder paste to a certain extent.
