learn nickel net of Solderability : comprehensive guide
welding yes electronic and manufacturing of basic Craftsmanship . This is use melt filling Metal or solder connect two metal surface of process . welding yes Electronic component Assemble middle essential of process , make sure quilt welding Material have good of Solderability crucial .
nickel net yes A sort of widely used for Various application of Material , include Electronic component , filter and Screen . learn nickel net of Solderability for make sure That Used product of quality and reliability crucial . exist Book comprehensive guide middle , us Will Discuss Influence nickel net Solderability of factor , and mention for accomplish good solder joint of basic Skill .
Influence Solderability of factor
have several factor meeting Influence nickel net of Solderability , include surface cleanliness , surface Roughness and oxide of exist . These factor meeting Butt welding material and nickel net of moisten ability and Adhesion force produce major Influence .
surface cleanliness : Influence Solderability of most The key factor one yes nickel net surface of cleanliness . any pollutants , For example Oil , grease or oxide , All meeting inhibition solder moisten surface . must make sure exist welding process Before thorough clean nickel net .
nickel net surface Roughness right That Solderability have Significantly Influence , right thing of effect , because Rough surface reduce Got it and solder Contact surfaces product , and then cause moisten and Adhesion question ; pass appropriate surface deal with method , Solve the problem of way , like fine polishing or plating wait means , so absolute Can efficient promote nickel net Solderability able .
oxide of exist : nickel net surface of Oxidation meeting Significantly Influence That Solderability . oxide meeting form barrier , Prevent solder moisten surface , thereby lead to solder joint bad . prevent Oxidation layer of form and exist welding Go remove any existing of oxide crucial .
accomplish good solder joint of Skill
for use nickel net accomplish good of solder joint , must obey the following hint :
1. surface Prepare : thorough clean nickel net surface , Remove any pollutants and oxide . use Suitable nickel surface of detergent and technology , For example Solvent , ultrasound clean or electrochemistry clean .
2. flux : welding forward exist nickel online Paint superior suitable of flux . flux helpful Remove oxide , improve wettability and Promote solder on the surface of flow . choose and nickel and specific welder art compatible of flux .
3 , welding temperature : Notice welding temperature . nickel have high melting point , therefore must use have suitable melt temperature of solder , and make sure temperature enough high by accomplish appropriate of moisten and Won’t right nickel net cause damage .
4. solder choose : choose and nickel compatible and mention for good wettability and adhesion of solder alloy . Lead-free solder , For example tin silver copper (SnAgCu) or tin silver (SnAg) alloy , usually used for welding nickel net .
5. welding technology : use appropriate of welding technology , For example control heating , adequate of flux application and suitable of welding time , by accomplish solder right nickel net of good moisten and Adhesion .
In short , learn nickel net of Solderability for make sure Electronic component and other use nickel net of product of quality and reliability crucial . pass consider surface cleanliness , surface Roughness and oxide of exist wait factor , and follow accomplish good solder joint of hint , manufacturer Can make sure nickel net of success welding . good of solder joint not only Can improve product of performance , besides help extend product of Service life and reliability .
