Product Overview
Sn42Bi58 solder npas yog cov hlau lead-dawb, eutectic alloy muaj li ntawm 42% Tin (Sn) thiab 58% Bismuth (Bi). Qhov kev sib xyaw tshwj xeeb no ua rau muaj qhov sib txawv me ntsis ntawm 138 degree, ua rau nws yog ib qho kev daws teeb meem zoo tshaj plaws rau cov ntawv thov uas cov khoom siv los yog cov khoom siv hluav taws xob kub kub yog qhov kev txhawj xeeb tseem ceeb. Lawv tau siv dav hauv Ball Grid Array (BGA) thiab Chip Scale Package (CSP) thev naus laus zis los tsim cov khoom siv hluav taws xob txhim khu kev qha thiab kev sib txuas.
Ntsiab nta & Cov txiaj ntsig
Ultra-Low Melting Point
Nrog rau eutectic melting point ntawm 138 degree, nws txo qis thermal stress thaum lub sij hawm reflow, tiv thaiv tshav kub-sensitive LEDs, saj zawg zog PCBs, thiab lwm yam ilv Cheebtsam ntawm kev puas tsuaj.
RoHS Raws Li & Eco-Tus phooj ywg
Raws li cov hlau lead-dawb alloy, nws ua tau raws li cov kev cai thoob ntiaj teb ib puag ncig zoo li RoHS, ua kom koj cov khoom muaj kev nyab xeeb rau tib neeg thiab lub ntiaj teb.
Zoo heev Solderability
Muab cov khoom ntub dej zoo heev, ua rau tag nrho, ci ntsa iab solder pob qij txha nrog tsawg kawg nkaus pob los yog bridging. Qhov no ua rau nws haum rau zoo -pitch printing daim ntaub ntawv mus rau 0.3mm.
Txhim khu kev ua tau zoo txhua yam
Muab lub zog sib koom ua ke txaus rau ntau daim ntawv thov, nrog lub zog tensile ib puag ncig 55 MPa thiab shear zog ntawm kwv yees li 27.8 kPa.

Ideal Applications
Sn42Bi58 solder balls yog qhov kev xaiv zoo tshaj plaws rau cov rooj sib txoos uas tsis tuaj yeem tiv taus siab - cov txheej txheem kub:
LED Assembly
Tiv thaiv rhiab LED chips thiab hloov tau yooj yim circuits thaum soldering.
Consumer Electronics
Lub xov tooj ntawm tes lub koob yees duab modules, cov khoom siv coj los siv, thiab lwm yam khoom siv PCBs.
Kub -Sensitive Cheebtsam
MEMS sensors, tej yam yas connectors, thiab cua sov-sensitive substrates.
Kauj ruam -Cov txheej txheem Soldering
Qhov twg cov kauj ruam tom ntej yuav tsum tshwm sim ntawm qhov ntsuas kub qis dua thawj zaug.
Kev txiav txim siab & Kev coj ua zoo tshaj plaws
Txawm hais tias zoo heev rau kev siv qis - kub, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias Sn -Bi alloys xws li Sn42Bi58 tuaj yeem nkig ntau dua li siab dua - kub SAC alloys. Lawv yog qhov zoo tshaj plaws rau cov ntawv thov yam tsis muaj kev cuam tshuam loj heev los yog thermal cycling kev ntxhov siab. Txhawm rau kom tau txais txiaj ntsig zoo, xyuas kom zoo cia (pom zoo 5-10℃rau solder paste) thiab siv nyob rau hauv nws lub txee lub neej los tswj kev luam ntawv.
Vim li cas thiaj xaiv Peb Sn42Bi58 Solder Balls?
Peb muab siab -purity, spherical Sn42Bi58 solder balls nrog zoo sib xws alloy muaj pes tsawg leeg thiab txoj kab uas hla tswj, xyuas kom meej pob txhim khu kev qha txuas thiab zoo heev co-planarity rau koj BGA thiab CSP pob. Peb cov khoom txhawb nqa cov txheej txheem sib dhos ua kom zoo rau siab -yield manufacturing.
Npaj los koom ua ke qis-Tub kub Soldering?
Ua kom koj cov txheej txheem sib dhos ua kom sov-sensitive designs. Tiv tauj peb hnub no rau cov ntaub ntawv qhia kev, cov qauv, thiab cov kws tshaj lij kev txhawb nqa los siv Sn42Bi58 hauv koj qhov project tom ntej.
