First, the product introduction
Victaulic solder paste is completely self-developed and has a number of national invention patents. Weite's series of no-clean lead-free solder paste is a solder paste that is developed according to IPC and JIS and other international standards to meet future environmental requirements. It uses a new rosin resin and composite anti-oxidation technology, and uses a low-oxidation sphere. Solder alloy powder and paste-like environmentally friendly flux with strong chemical stability. Suitable for all kinds of precision welding in the electronic assembly process SMT production.
We only have a wide range of solder pastes, including mobile phone special solder paste, chip semiconductor package solder paste, LED special solder paste, thermal module low temperature solder paste and so on. The alloy has a melting point of up to 138 °C and a maximum of 287 °C. The alloys are available in a wide range of alloys to suit a wide range of industries and products.
Second, solder paste characteristics

Third, the application guide
1, save and use
The product should be sealed and stored at 2-10 ° C with a shelf life of 6 months (from the date of production).
The solder paste should be removed from the freezer before use. Leave the bottle cap open and leave it at room temperature. To achieve complete heat balance,
It is recommended to have a warm-up time of at least 4 hours.
After returning to the temperature, the solder paste should be thoroughly stirred by a manual or solder paste automatic mixer for 1-3 minutes before use, so that the solder paste and the solder alloy powder are thoroughly stirred to avoid unevenness caused by storage. The specific mixing time should be based on the stirring speed,
The ambient temperature and other factors are determined.
Do not use used solder paste in the same container as unused solder paste. After the solder paste is opened, if there is any solder paste left in the jar, it should not be placed in the air. The lid should be tightened as soon as possible.
2, printing
The recommended printing parameters for solder paste are as follows:
Scraper: stainless steel scraper or polyurethane scraper
Scraper printing angle: 40 ° ~ 60 °
Printing method: suitable for manual printing, semi-automatic or fully automatic machine printing
Printing speed: 20 ~ 100mm / sec
Printing residence time: After solder paste printing, component placement and soldering should be completed as soon as possible, and the residence time should not exceed 12 hours.
In order to avoid affecting component placement and soldering effect temperature/humidity: temperature 25±5°C, relative humidity 50±10%
3, point coating
The appropriate needle can be selected and the appropriate air pressure adjusted according to the size of the product and the dispensing speed.
4, packaging
Bottled 500g package;

Syringes: 10g / support, 30g / support, 100g / support, 200g / support, 500g / support, 1250g / support can also be packaged according to customer needs.
