Lead-free solder paste

Product type: SMT solder paste

Huateng New Material solder paste is a non cleaning solder paste developed and produced in accordance with IPC, JIS and other international standards. It is made of new rosin resin and composite oxidation resistance technology, spherical solder alloy powder with low oxidation degree and paste environment-friendly flux with strong chemical stability. It is suitable for various precision welding produced by electronic assembly process SMT.

Detail

Huateng New Material solder paste has a complete range of types, many alloy models, and a wide range of alloy melting points (138 ℃~287 ℃), which can meet the selection and application of various industries and products.Huateng New Material solder paste is divided into mobile phone solder paste, chip semiconductor packag-ing solder paste, LED solder paste, heat dissipation module low-temperature solder paste, etc.

Product features:

1、 Good printing rolling and leak printing performance, and fine printing can also be completed for pads with

spacing as low as 0.4mm;

2、The continuous printing time is long, there is basically no collapse after several hours of printing, the viscosity

change is small, and the SMD components are not easy to shift;

3、It has excellent welding performance and can complete good wetting in different parts;

4、Good welding performance can still be achieved in a wide range of reflow temperature;

5、There are few residues after welding, the appearance is transparent, the insulation impedance is high, and

PCB will not be corroded, which can meet the requirements of no washing;

6、It has better ICT test performance and will not produce false judgment;

7、It can adapt to the welding of PCB special gold-plated materials without irritating smell.

Lead-free solder paste:

Alloy composition	Melting point (℃)	Characteristic	Application area
Sn96.5Ag3.0Cu0.5	217-221	Field of application General purpose products with high silver content, high welding performance and good appearance, pin measurement, low void ratio, excellent mechanical properties and heat resistance fatigue performance.	Standard SAC alloy is used for LED chip, chip solidification, semiconductor packaging, computer motherboard, precision medical instruments, mobile phones, tablet computers, etc. that can withstand high temperature welding.
Sn98.5Ag1.0Cu0.5	217-226	General purpose product with medium silver content, high welding performance, good mechanical properties and heat resistance fatigue performance.	Low cost SAC alloy is used for most SMT applications, such as computer motherboards, communication equipment boards, home appliance boards, mobile phones, PPC etc.
Sn99Ag0.3Cu0.7	217-227	General purpose products with low silver content, good welding performance, good mechanical properties and heat resistance fatigue performance.	Low cost SAC alloy is used for most SMT applications, such as communication equip ment boards, home appliance boards, LED assembly, photovoltaic terminal boxes, etc.
Sn42Bi58	138	Low temperature Sn Bi eutectic alloy, excellent printability, good wettability and tin bead resistance, bright solder spots.	Products or components suitable for low temperature welding, such as thermistor welding, LED components, tuner, heat dissipation module, etc.
Sn42Bi57.6Ag0.4	138-143	At low temperature, silver is added to improve the vibration drop property, good wettability and tin bead resistance of tin bismuth alloy.	Products or components suitable for low temperature welding, such as thermal sensor welding, LED components, high frequency tuner, double side plate through-hole once reflow process, etc.
Sn64Bi35Ag1.0	139-187	The vibration drop property of Sn Bi alloy is improved by adding silver when the Bi content is reduced, but the temperature is increased, and the wettability and tin bead resistance are good.	Products or components suitable for low temperature welding, such as thermistor, tuner, remote controller, telephone, LED lamp, etc.

Other alloy grades can be produced according to customer requirements。
