welding yes electronic manufacture middle of The essential Craftsmanship , make sure reliable durable of Connector for Electronic equipment of performance and Service life crucial . exist welding nickel net hour , maximum limit land improve Solderability for accomplish solid reliable Connector crucial .
nickel net because of Excellent of conductivity , Durability and Corrosion resistance and widely used At electronic application . However , because That surface able compare Low , nickel net exist welding hour possible meeting bring challenge . maximum limit land improve nickel net of Solderability need carefulness consider surface deal with , welding Material and Craftsmanship parameter .
for maximize nickel net Solderability , make sure do it That surface at ideal state arrive close important . this involving Clear surface all pollutants , type very many , include oil stains , Oxidation layer as well as other very have possible Influence solder wettability the remains . this Once passed Procedure usually pass use Suitable Solvent and detergent conduct comprehensive and thorough surface clean and go fat Come Finish . in addition , With the help of sandblasting or polish wait Manipulator part , so absolute Can further Enhance surface texture , thereby Significantly promote solder wettability able .
correct choose welding Material for maximum limit land improve nickel net of Solderability also crucial . choose correct of solder alloy and flux for make sure solder right nickel surface of good Adhesion and moisten crucial . Lead-free solder alloy ( For example SAC305 or SnCu ) because of right environment and healthy of benefit and become electronic application of First choice . rosin base or water soluble flux usually used for Promote solder moisten and maximum limit land reduce welding process middle of surface Oxidation .
Apart from surface deal with and welding Material outside , optimization welder art parameter for maximum limit land improve nickel net of Solderability also crucial . this include control welding operate period of temperature , time and pressure . appropriate of Heat pipe reason for make sure solder Uniform flow and moisten nickel surface and No damage grid crucial . answer carefulness control welding time and pressure , Just in case end grid Been on Spend heating and mechanical stress , thereby lead to Warp or deformation .
also , use appropriate of welding technology , For example Reflow soldering or wave soldering , also meeting Influence nickel net of Solderability . For example , Reflow soldering Can better land control welding temperature and time , thereby form Even consistent , Even reliable Connector . on the other hand , wave soldering catch possible Suitable Larger area of application , in entire grid Can once welding .
In short , want maximum limit land improve nickel net of Solderability , by get reliable , durable of Connector , need use A sort of system method , include surface deal with , welding Material and Craftsmanship parameter . pass carefulness consider These factor and implement optimal practice , manufacturer Can make sure electronic components middle of Connector solid reliable , finally improve product performance and Service life .
