In soldering, the most commonly used material is Solder paste. The Solder paste manufacturer produces Lead-free solder paste, which is an indispensable raw material for component assembly across the electronics industry.

With the development of the electronics industry, Solder Paste consumption has gradually increased. Partners will notice that the Solder paste price on the market is on an upward trend. JiajinYuanxicream manufacturers now walk you through how the price of lead-free solder paste changes.

Does the high unit price of Lead-free solder paste really correspond to better solder-joint quality?

As everyone knows, solder paste is highly adhesive and can bond PCB circuit boards tightly to electronic components so they are soldered together; how easily they can be reworked depends on how robust the solder joints are.

A widely used alloy today is Sn63Pb37 Solder Paste, with a melting point (and solidus) of 183℃, while the tin-silver-copper alloy has a liquidus of 218℃. By soldering these two alloys with wires of different proportions and then calibrating the joints using a generalized method and a spectrometer, you will find that Sn63Pb37 has a relatively clear advantage in the measured data.

Is using a larger quantity of Solder paste always better?

The amount of solder paste used in soldering is considerable and accounts for a large share of the soldering cost. Solder paste is made of different alloy compositions, so its price naturally varies. Tin-silver-copper Alloy Solder paste, which makes up the majority, is also priced quite high. The more solder paste used, the higher the corresponding cost.

Solder paste applications require a relatively high level of reliability from electronic components’for example, navigation bars, LCD TV mainboards, and KTV sound systems. Tin-silver-copper alloy solder has a marked advantage in this range: compared with other solder pastes it offers better wettability and protection, and the resulting solder joints are stronger.
