What kind of raw material is used for tin wire
Oct 20, 2022
10-20
2022
Lead-free solder wire is fully tested by SGS. In the dust-free and environmental protection special workshop, high-purity environmentally friendly tin ingots, unique flux formula, strict implementation of the ISO quality management system, and the introduction of German direct-reading spectrometers to control the quality, produce lead-free solder wires that meet RoHS standards.
Lead-free low temperature solder wire

Lead-free low-temperature solder wire is a low-melting lead-free environmentally friendly solder wire divided according to the melting point temperature of the solder wire. Refined with professional equipment and special craftsmanship. The proportion of the alloy is reasonable, and the flux is made of high-quality modified resin, organic activator and various additives, so that the low-temperature lead-free solder wire also has its special welding performance and application in the lead-free process.
The role of lead-free solder wire and tin bar

Use a constant temperature soldering iron when soldering.
1. There are two types of lead-free tin wire containing silver: 0.3 silver lead-free tin wire and 3 silver lead-free tin wire. The melting point of silver-containing lead-free tin wire is 217 degrees, and the soldering temperature is almost 260 degrees.
2. There are few customers for solid core lead-free tin wire, which is mainly used for the welding of special products. The melting point of solid core lead-free tin wire is 220 degrees, and the welding temperature is adjusted to 260-270 degrees for comparison.
Analysis of physical properties of tin-bismuth alloy

Bismuth is a small metal that has only attracted attention in recent years. Its element is bismuth ingot, but its element is very small, most of which are in the form of bismuth oxide, and some bismuth alloys appear. Tin-bismuth alloy is one of them.
Tin-bismuth alloy is an environmentally friendly alloy. At room temperature, it is solid and silver-white, with a melting point of 138 degrees and a solid-liquid volume shrinkage rate of 0.051%, with strong permeability.

2022
Where is the position of high-temperature solder wire: The solder wire used for manual electronic component welding is composed of tin alloy and additives. During electronic welding, the solder wire is matched with the electric soldering iron, and the high-quality electric soldering iron provides stable and continuous melting heat , The solder wire is added to the surface and gap of the electronic original device as a filler metal, and the fixed electronic original device becomes the main component of welding.

2022
The tin wire will melt after high temperature, soldering the components and the circuit board together. Tin is a conductive metal. The function is to solder the components to the circuit board. The function of the circuit board is to replace the wire connection of the earliest era, so that these electronic components that need to be combined and connected are concentrated together. The birth of the printed circuit board is a cross-generational product.

2022
For a reflow process without cleaning, low residues are often required for cosmetic or functional effects, examples of functional requirements include "probing test overlays with solder flux residues tested in circuits and Make electrical contact between the plug-in contact and the surfacing layer or between the plug-in contact and the through hole near the reflow solder joint”.
