Recently, I heard many customers inquiring about lead-free soldering. I often hear them ask what the lead content should bePPMThen what is the lead contentPPMBetter. Everyone is quite clear that the quality requirements for lead-free solder wire in products are very high. In terms of standards, the content of lead metal in the EU standards is all less than1000m. In the tin products industry, the industry standard requirement for lead content in tin wire is less than300mOr, if there is a higher requirement to produce halogen-free and lead-free tin wire, thenm......

Solder wire is a welding material composed of tin alloy and flux. Lead solder alloy is divided into tin-lead and lead flux. Environmentally friendly solder is composed of tin-copper alloy and lead-free flux. The main function of solder wire is to fill, repair or connect the primary soldering material between two electronic components. Can all materials be welded with solder wire? Today, the solder paste manufacturer will take you to learn about which ones are suitable for soldering? The principle of soldering and the principle of soldering metals with high solderability is to......

There are many kinds of solder paste. Depending on different methods, the same solder paste can belong to different types. Everyone knows that there are two types, lead-free solder paste and leaded solder paste. According to the different working temperatures, the same lead-free solder paste can be classified into lead-free high-temperature solder paste, lead-free medium-temperature solder paste and lead-free low-temperature solder paste. The classification standards commonly used by general solder paste manufacturers are consistent with those of the users. Here is an introduction: 1. Analysis of solder paste classification by alloy:1Leaded solder paste(General suitability......

Engaged inSMTFriends in the surface mount technology (SMT) processing industry should have already come into contact with solder paste. When purchasing this material, they usually select it carefully and need to negotiate with the solder manufacturer for samples. This material is quite important. So, what role does such an important material play? Today, the solder paste manufacturer is here to talk to everyone about: In the past70During that period, due to the rise of surface mount technology, it was actuallySMT. This is for printing and brushing on the through holes of printed circuit boards......
