Solder tin paste is a new type of solder material that comes with SMT.
Solder paste is a complex system that is made of a paste of solder powder, flux, and other additives.
At the normal temperature, the solder tin paste has a certain viscosity, and the electronic component can be initially adhered to a predetermined position.
At the soldering temperature, the soldered component and the printed circuit pad are soldered together (Permanent connection.) with the evaporation of the solvent and some additives.
Before the opening, the temperature of the solder paste should be raised to the ambient temperature (25℃), and the temperature return time should be about 3-4 hours. (It is forbidden to use other heaters to raise the temperature instantaneously.)
After the solder paste is opened, it is recommended to use it within 24 hours at room temperature.
Placed in the air for a long time, the solder paste will become a tin block due to moisture absorption.
The indoor temperature should be controlled at 22-28℃, and the humidity RH30-60% is the best working environment.
To wipe the wrong substrate, it is recommended to use industrial alcohol or industrial cleaner.
The solder paste should be kept at room temperature.
The solder paste should be used for 12 months.
The solder paste should not be placed in the sun.
The measurement allowed error is ±1.0-2.0m.
Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
The weight mentioned in the product description and pictures is gross weight, and the only difference between different models of products is weight.
In order to prevent counterfeit or pirated products, we will continue to update the product packaging, but this does not affect the quality and use of the product, the new and old packaging will be shipped randomly.
Keep away from children.
Avoid contacting with eyes.
Use only with adequate ventilation.
The solder paste contains organic solvent. Avoid repeated contact with skin. If the solder paste gets on your skin, wipe it off with alcohol and rinse thoroughly with water.
In order to be cautious, in the operation, the smoke released by the solvent during operation should be avoided as much as possible, and the skin and mucous membrane tissues should not be contacted for too long. Avoid repeated breathing of vapor.
New technical support, unique chemical formula provides excellent wetting, to ensure high reliability. Adapted to the mobile phone repair industry, computer digital service industries and high-precision circuit board soldering SMT/BGA soldering processes.
The viscosity is moderate, there is almost no patch collapse, and the components do not shift.
The storage time is up to 24 months in a refrigerated environment. Unique high-quality solder tin paste makes the adhesion is long-lasting, it is not easy to dry, and the viscosity time is up to 48 hours.
The residue is colorless and transparent, does not affect the detection, disposable and excellent cleaning performance.
Use of efficient energy thixotropic agents, printing and preheating collapse, special solder ensure a good printing and fine pattern.
Uncompromising performance in an ultra-light ultra-thin body, heavyweight performance without the weight. Fine and flexible packaging, delicate appearance.
