Technical field
The present invention relates to a kind of solder(ing) paste, more particularly to a kind of stamp-mounting-paper diode welds special scolding tin
The preparation method of cream.
Background technology
Solder(ing) paste is accompanied by a kind of novel welding material that SMT arises at the historic moment.Solder(ing) paste is a complicated system, is
The lotion formed by solder powder, scaling powder and other additives mixeds.Solder(ing) paste has certain viscosity at normal temperatures, can incite somebody to action
Electronic component is just bonded at commitment positions,, will be by weldering component with the volatilization of solvent and portions additive under welding temperature
It is permanently connected with being formed together with printed circuit pad solder.
Solder(ing) paste is widely used in high-accuracy electronic component, wherein, on the one hand solder(ing) paste can cause electronics
Component and air insulated, and then realize isolation and anti-oxidation；On the other hand solder(ing) paste can ensure the weldering of electronic component
Connect that performance is strong, and then the effect realized high resistance and prevent rosin joint phenomenon from occurring.As electronic technology constantly develops, people couple
The welding quality proposed requirement of electronic product also more and more higher；Clearly to know welding quality, increasing electronics
Product detects its welding performance in postwelding using probe test.
At present, the difficult point of stamp-mounting-paper diode leadless soldering tin paste investigative technique is primarily present three aspects：First, activity is weak.By
In lead-free solder solderability well below tin-lead solder, so its activity performance to scaling powder requires higher.It is based on
Environmental requirement, present solder(ing) paste tend to leave, so activating agent uses organic acid more.Because its effect is soft, bring
Corrosivity it is minimum, will not typically cause larger harm, but the solder(ing) paste activity prepared is weak, solderability is poor, easily causes
Rosin joint.2nd, postwelding residue is more.It is viscous often to add higher boiling, height in order to extend the holding time of solder(ing) paste for most of producers
Degree, the cosolvent of low volatility slow down evaporation rate, can not be printed with ensuring solder(ing) paste not solidify quickly when in use.
Printed board assembly is when being rapidly heated when this has resulted in weld heating, the solvent in solder(ing) paste can not volatilize completely it is clean and
Postwelding forms a large amount of residuals, and not only outward appearance is not good enough, also tacky.3rd, thixotropy is poor.Different printing technique needs different viscosities scope
Solder(ing) paste, especially for the Reflow Soldering of slight gap, the thixotropic property of solder(ing) paste is particularly important.
