Cov pob solder muaj lub siab zoo, siab purity, zoo heev conductivity, thiab soldering stability, ua kom siab - ceev interconnects, txhim kho tshav kub dissipation efficiency, thiab kev txhawb rau lub miniaturization ntawm electronics.
High-Qhov tseeb thiab siab-Txoj kev ntseeg tau txuas
Cov npas solder nthuav tawm qhov siab tshaj plaws thiab micron - theem txoj kab uas hla tolerances (mus txog 80μm), kom ntseeg tau tias kev sib raug zoo thiab kev sib txuas hauv cov pob khoom siab heev xws li BGA / CSP. Lawv du, tsis xws luag-dawb nto thiab cov pa oxygen tsawg txo qhov tsis xws luag xws li txias solder pob qij txha thiab bridging, uas ua rau cov solder joint yield tsis tu ncua siab tshaj 99.6%.
Kev them nyiaj yug rau High -Density thiab Miniaturized Ntim
Nrog rau kev loj hlob tawg nyob rau hauv nti I / O tus pin suav, ib txwm pins tsis txaus kom tau raws li qhov xav tau ntawm qhov chaw. Solder balls hloov pins kom ua tiav cov txheej txheem matrix, nce kev sib txuas ceev los ntawm 5-10 zaug thiab hloov mus rau qhov kev xav tau ntawm cov kev xav tau ntawm 0.15mm pads thiab 0.25mm suab. Nyob rau hauv kev sib piv ntawm miniaturization, 10-30μm solder balls twb tau siv nyob rau hauv 3D IC thiab HBM nco ntim.
Kev ua tau zoo ntawm hluav taws xob thiab cua sov: Cov khoom siv hluav taws xob luv luv ntawm cov teeb liab kis tau tus mob, txo cov kab mob parasitic capacitance thiab inductance, txhim kho siab -frequency signal integrity, thiab tau sib xws nrog siab - ceev interfaces xws li PCIe 5.0/6.0. Thaum ua ke nrog cov ncej tooj liab, thermal conductivity yog ntau dua 40% siab dua cov tin ntshiab, zoo txo cov cua sov dissipation siab ntawm siab - cov khoom siv fais fab xws li AI chips thiab automotive electronics.
Muaj zog tiv thaiv ib puag ncig thiab kev sib raug zoo: Mainstream lead-dawb alloys (xws li Sn96.5Ag3Cu0.5) yog siv, ua raws li RoHS ib puag ncig cov qauv. Haum rau ntau yam txheej txheem xws li laser jetting thiab automated ball placement, nws txhawb nitrogen- tiv thaiv soldering, txo oxidation, thiab enables tag nrho automated ntau lawm.
