The correct usage method of no-clean solder materials - Shenzhen JJY

No-cleaning solderWhat is the correct way to use materials? Nowadays, the electronics industry is developing at an increasingly rapid pace, and many industries are constantly expanding and developing.SMTIt is also an indispensable part of the current society, and many fields involve it. Why did traditional industries always flake off solder when using it in the past and some bad situations occurred? Therefore, a new type of "no-clean" solder emerged to meet the needs of the development of the electronics industry. But what is the function of this one and how to use it? Let's take a look next:

No-cleaning flux is a new type of flux that does not contain halide active agents and does not require cleaning after soldering. The use of this type of flux not only saves the investment in cleaning equipment and cleaning solvents, but also reduces the pollution to the environment caused by the discharge of waste gas and waste water. Therefore, replacing traditional fluxes with no-cleaning fluxes has significant economic and social benefits.

When using solder containing no-clean flux, it has the advantages of no environmental pollution, low cost, short production cycle and simple process. No-clean flux will be the trend of industry development.

Advantages of no-cleaning flux:

It has good solderability, full solder joints, and no defects such as solder beads or bridging

Non-toxic, does not pollute the environment and is safe to operate

After welding, the plate surface is dry, non-corrosive and does not stick to the plate

It has the ability to conduct online testing after welding

withSMDandPCBThe board has corresponding material compatibility

After welding, the surface insulation resistance value complies with the regulations.SIR)

Adapt to welding processes (dip welding, foaming, spraying, coating, etc.)

No-cleaning solder wireIt is classified into halogen-containing type and halogen-free type according to whether the solid flux used contains halogen. For halogen-containing typesMLIt indicates that it is for halogen-free useMIndicate. An example of the grade of halogen-containing no-clean solder wire is expressed as:MLSn60 An example of the grade of halogen-free no-clean solder wire is expressed as:MSn60 Specification and marking The specifications of the no-clean solder wire consist of the grade, the amount of flux and the wire diameter. If the welding content is60%The wire diameter is0.8mm,The flux content is1.0%. The marking of halogen-containing no-clean solder wire is:MLSn60Φ0.8(1.0%). Appearance quality: The surface of the no-clean solder wire should be smooth and clean, without cracks, oil stains or inclusions. Function: When soldering objects with tin, it is necessary to apply sulfuric acid or solder paste to the surface to be soldered. The purpose is to clean the soldering surface so that solder can be used. No-clean solder wire is this type of solder wire that has already been filled with rosin and other substances, so there is no need to use solder paste or the like during the soldering process. This provides convenience for consumers to operate.
