Melting point of lead-free tin wire
Oct 21, 2022
10-21
2022
Lead-free tin wire is used for high temperature solder joints such as Luokou bulbs, and the melting point of lead-free tin wire is 217-227 degrees. As the melting temperature of the tin wire increases, the volatilization rate of the flux is also accelerated, which is likely to cause insufficient tin fluidity, resulting in tin tips, tin bridges or wire drawing, which seriously affect the soldering effect.
How to solve the lead-free solder wire slag

How to deal with the problem of excessive tin dross during the use of lead-free tin wire solder? For the hand dip furnace, the problem of excessive tin dross is not very normal, and this problem rarely occurs. The customer shows that the tin surface turns yellow or fades Purple, this situation may be that the furnace temperature deviation is too large during the operation of the customer. For example, the temperature is too high or the tin furnace has not been cleaned for too long, resulting in too much anti-oxidation loss and no effect. In this case, as long as Adding a small amount of anti-oxidant or cleaning the furnace, and then controlling the temperature of the tin furnace can be solved.
What kind of raw material is used for tin wire

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.
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.

Instructions for handling lead-free solder fluxes
Oct 14, 2022

2022
1. The specific gravity of the solder flux is generally 0.810~0.830 (20°C), and the specific gravity of the solder flux varies with the temperature. Each time the temperature increases by one degree, the specific gravity of the solder flux decreases by 0.001. The actual operation can be appropriately increased or decreased according to the temperature of the job site. Make sure the working conditions are consistent.
Performance Requirements for Lead-Free Solder Flux
Oct 14, 2022

2022
1. The lead-free solder flux must have good thermal stability (to ensure that it will not decompose and fail at higher solder temperatures.);
2. The lead-free solder flux must have a certain chemical activity (to ensure the ability to remove the oxide layer);
3. Lead-free solder flux should have good wettability and promote the expansion of solder (to ensure better soldering effect);

We produce leaded solder wire and lead-free SNCU solder wire inside is hollow, this The design is to store the flux (rosin), so that the flux can be added evenly when adding solder. The role of the solder wire: to meet the electrical conductivity requirements of components on the circuit and the fixing requirements of components on the PCB board.
