exist involving electronic , Aerospace and car wait field application middle , nickel net because of unique physics and chemical properties and quilt widely used . nickel net Solderability as That performance evaluate The essential index , right truly of ensure electronic dynamic link library and components Function stability and persistence have Decide Qualitative Influence . of great importance , Influence too Pass far-reaching ! for discuss in depth Influence nickel net Solderability factor , Influence of Element , and soon beg optimization and promote Strategy by achieve excellence able Target , This thesis describe Will focus exist this one core question , need solve of matter , and try by A sort of complex and easy to produce Confuse Way conduct Elaborate .
exist explore Influence nickel net Solderability factor hour , first need clear yes , Material itself chemical composition , microscopic structure , surface state as well as and solder between interaction mechanism all right That Solderability produce direct Influence . of great importance , Influence too Pass far-reaching ! Come ! I First for you Lift Case son , nickel purity , alloy element content , grain size distributed , Oxidation layer exist or not as well as surface clean degree wait factor , Influence of Element , All very have possible Significantly Change change nickel net and solder combine quality and stability , Incomparable happiness !
further land , constantly optimization nickel net Solderability Strategy often need comprehensive consider above factor , Influence of Element , and pass Adjustment Craftsmanship parameter〔 like temperature , time , pressure wait〕 as well as use specific surface deal with technology〔 like electroless plating , physics gas phase deposition wait〕 Come accomplish . introduce appropriate flux , by improve nickel net surface wettability and Promote solder diffusion and fill seam , also yes promote Solderability important means .
Specific implementation process middle , conduct of process middle , must Must take into account each factor between complex interaction , avoid over optimization and promote guide To Increased costs or performance Degenerate… Establish comprehensive Model , smoothly pass right different parameter combination system experiment analyze , impressive revel night view ! by turn up optimal balance point , appear Particularly important . This kind of complex and subtle optimization and promote process not only test With project teacher expertise and technology ability , also right equipment Accuracy , operator experience as well as entire Production Process Controllability propose Got it compare Gao Yao beg .
I personal think Influence nickel net Solderability factor Quite a few Sample and complex , impressive revel night sky ! optimization and promote this one performance need Never few indivual Dimensions Set off , Incomparable happiness ! comprehensive consider Material characteristic , Craftsmanship condition and surface deal with wait Quite a few indivual aspect , Each has his or her own strengths , complement each other , by accomplish Efficient , Stablize and economy solve Certainly plan .
1 , surface cleanliness : Influence nickel net Solderability of most The key factor one yes That surface of cleanliness . any pollutants , like Oil , oxide or other the remains , All meeting hinder nickel net surface solder of moisten and bonding . therefore , thorough of clean and surface Processing technology for make sure good of Solderability crucial . this Can pass Solvent Clean , base Clean or use Abrasive of mechanical Clean wait method Come accomplish .
2 , surface Roughness : nickel net of surface Roughness also able right That Solderability produce major Influence . Rough of surface meeting lead to solder moisten and Adhesion bad , thereby lead to solder joint Fragile and No Depend on . therefore , pass electrolysis polishing or mechanical polishing wait Craftsmanship carefulness control nickel net of surface Roughness by get smooth Uniform of surface Very important .
3 , surface Oxidation : nickel very easy occur Oxidation , especially in high temperature Down , Can exist That surface form layer Nickel oxide . Should Oxidation layer meeting hinder solder moisten and bonding , lead to Solderability Poor . therefore , pass Handle it correctly and store nickel net , as well as use Protect coating or surface deal with Come prevent Oxidation , maximum limit land reduce Oxidation layer of form Very important .
4 , alloy Element : mesh Used Nickel alloy of Element also meeting Influence That Solderability . some alloy element , like chromium or titanium , Can improve nickel surface solder of wettability and adhesion . therefore , for specific welder art choose correct of alloy Element for accomplish good of Solderability crucial .
5 , welder art parameter : Apart from nickel net itself of performance outside , welder art parameter , like temperature , time and flux chemical composition , also meeting Influence nickel net of Solderability . optimization These parameter by make sure appropriate of moisten , Adhesion and form firm of solder joint Very important .
nickel net Solderability right That exist each field application performance arrive close important , special especially yes exist it , constantly optimization The key factor like surface cleanliness , Roughness , Oxidation degree , alloy Element as well as welder art parameter , abnormal witty ! able truly of ensure nickel net Related dynamic link library and components stability and persistence , thereby promote Electronic equipment and system overall quality and efficacy , Can imagine this Once passed Procedure full Got it technology challenge and detail consider .
