A SAC alloy-coated tooj liab core pob yog lub pob sib xyaw nrog cov tub ntxhais tooj liab thiab txheej txheej txheej plated nrog tin-silver tooj liab (SAC) alloy. Nws feem ntau yog siv rau hauv siab - kev ntseeg tau hauv lub ntim khoom siv hluav taws xob, sib txuas lub zog siab ntawm tooj liab nrog kev ua haujlwm zoo heev ntawm SAC alloy.
High-purity tooj liab npas, feem ntau nrog ib txoj kab uas hla ntawm 0.03-0.5 hli, muab cov neeg kho tshuab zoo heev thiab ib tug zoo thermal txoj kev.
Cov txheej txheem nruab nrab (yeem): Ib txheej 2-3 μm tuab npib tsib xee plating txheej txhawm rau txhawm rau cuam tshuam intermetallic compound (IMC) diffusion ntawm tooj liab thiab sab nraud solder, txhim kho kev sib txuas ruaj khov.
Txheej txheej: A 3-30 μm tuab SAC alloy plating txheej (xws li SAC305 lossis SAC405), uas yog ib feem uas tau koom nrog cov txheej txheem soldering thiab muaj cov dej noo zoo, qaug zog tiv thaiv, thiab cov hlau lead-dawb tiv thaiv ib puag ncig.
High thermal conductivity: Cov tub ntxhais tooj liab muaj qhov thermal conductivity zoo dua li cov pob zeb ntshiab, pab kom cov cua sov los ntawm cov nti sai sai thiab txo qhov kev pheej hmoo ntawm kev kub ntxhov.
Muaj zog tiv thaiv rau thermal qaug zog: SAC alloy nws tus kheej muaj kev nkag tau zoo dua li cov tsoos Sn -Pb solder, thiab nws tsis tshua muaj kev tawg thaum rov ua dua thermal.
Kev ntseeg siab ntawm kev sib txuas siab: Tsim nyog rau cov ntawv ntim qib siab xws li BGA, CSP, thiab FC, tshwj xeeb tshaj yog tsim rau siab - cov khoom siv hluav taws xob thiab siab - qhov sib txawv ntawm qhov sib txawv.
