Tin-plated copper foil yog cov khoom sib xyaw uas tsim los ntawm kev tso cov tin txheej rau ntawm cov ntawv ci tooj liab substrate. Nws muab cov khoom siv hluav taws xob siab ntawm tooj liab nrog cov khoom tiv thaiv ntawm tin, tuav txoj haujlwm tseem ceeb hauv kev lag luam hluav taws xob. Nws lub substrate thickness feem ntau yog nyob nruab nrab ntawm 0.035 thiab 0.15 hli, thiab cov tin txheej thickness yog tsis tsawg tshaj li 0.3 μm, uas yuav tsum tau kho nyob rau hauv ib ncig ntawm 2.0 μm raws li daim ntawv thov. Lub adhesion ntawm txheej thiab substrate mus txog qib 5B, zoo tiv thaiv delamination thaum ua.
Hais txog kev ua tau zoo, tin -plated copper foil nthuav tawm ntau yam zoo. Hais txog kev ua tau zoo, cov txheej txheem tin ntshiab tau txais los ntawm cov txheej txheem uas tsis yog - soldering tswj qhov chaw tiv thaiv ntawm 0.1 ~ 0.15Ω, thiab kev tiv thaiv kev sib cuag ntawm ob -sided tin- cov khoom plated tuaj yeem tswj tau qis dua 0.5mΩ, ua tau raws li qhov yuav tsum tau ua ntawm kev sib kis ntawm precision circuits. Nyob rau hauv cov nqe lus ntawm corrosion kuj, txheej tiv thaiv tsim los ntawm tin plating ho slows down oxidation txheej txheem thiab zoo heev ncua sij hawm cov khoom tsis ua hauj lwm lub sij hawm nyob rau hauv ib puag ncig ntub. Txawm tias tom qab 3000 qhov kub thiab txias los ntawm -40℃mus rau 125 degree, lub ci tin plating tswj cov pob qij txha ruaj khov. Mechanically, nws combines zoo yooj thiab qaug zog lub zog, tiv thaiv breakage thaum khoov thiab winding. Lub substrate kev ua tau zoo degradation tom qab electroplating tsawg dua 10%, ua rau nws tsim nyog rau txoj kev molding complex.
Hais txog kev siv, tin -plated tooj liab ntawv ci muaj dav siv tau. Hauv cov neeg siv khoom siv hluav taws xob, matte tin plating cov khoom tuaj yeem ua tiav cov khoom siv ruaj khov nrog cov kab dav / qhov sib txawv ntawm 30μm thiab feem ntau siv hauv kev tsim hluav taws xob hloov hluav taws xob. Hauv cov khoom siv hluav taws xob hauv tsheb, nws qhov siab -kub cycling kuj ua tau raws li qhov xav tau ntawm cov khoom xws li ECUs. Siv ob -sided tin plating hauv photovoltaic hlws ris lub thawv tuaj yeem txhim kho lub zog hloov pauv ntawm 0.3%. Tsis tas li ntawd, nws tuaj yeem siv los ua ib txheej electromagnetic yoj tiv thaiv txheej hauv cov khoom siv sib txuas lus lossis leverage etching precision zoo nyob rau hauv siab - ntom ntom Circuit Court board manufacturing.
Nyob rau hauv cov nqe lus ntawm txoj kev loj hlob, breakthroughs tau tiav nyob rau hauv ntsuab tin plating tshuab. Lub cyanide-dawb plating tov system txo tus nqi COD ntawm cov dej khib nyiab los ntawm 5000 mg / L mus rau 50 mg / L, nrog cov tin rov qab tus nqi siab tshaj 99.9%. Tus tshiab Sn-Bi-Ag ternary alloy txheej muaj qhov melting point tsawg li 138℃thiab lub neej nkag siab tshaj 10,000 teev ntawm 125 degree, ntxiv nthuav nws qhov chaw thov hauv thaj chaw xws li cov khoom siv hluav taws xob hloov tau yooj yim.
