Raws li cov khoom siv hluav taws xob hloov mus rau ntau zaus, kev nrawm dua, thiab kev ua haujlwm me me, kev xaiv cov khoom siv raw yuav tsum coj mus rau hauv tus account hauv qab no:
Kev siv dav dav ntawm High-Frequency Substrates: Qhov kev thov rau cov khoom siv uas tsis tshua muaj dielectric poob tau nce hauv cov haujlwm xws li 5G kev sib txuas lus thiab tsheb radar; yog li ntawd, kev sib koom ua lag luam rau PTFE-raws li substrates (Df Tsawg dua lossis sib npaug rau 0.001) thiab ceramic-cov substrates puv (Df Tsawg dua lossis sib npaug rau 0.002) txuas ntxiv nthuav dav.
Kev kho dua tshiab ntawm Flexible Substrates: Wearable devices and foldable smartphones are driving the evolution of PI films to ultra-thin profiles (Less than or equal to 12.5 μm) and high modulus values (Ntau dua los yog sib npaug rau 4 GPa). Raws li qhov tshwm sim, LCP (Liquid Crystal Polymer) cov yeeb yaj kiab tau pib hloov PI hauv qee yam kev siv vim lawv qhov nqus dej tsawg heev (tsawg dua lossis sib npaug li 0.04%).
Heightened Environmental Standards: EU cov cai xws li RoHS thiab REACH txwv tsis pub siv cov khoom phom sij- suav nrog cov hlau lead thiab halogens- ua cov hlau lead- cov solders dawb (tshwj xeeb yog Sn-Ag-Cu system) thiab eco- daws teeb meem ntawm cov phooj ywg kev lag luam tus qauv.
Kev xaiv cov khoom yuav tsum muaj kev ntsuam xyuas tag nrho ntawm cov kev xav tau ntawm kev ua haujlwm, kev txwv nyiaj txiag, thiab kev tsim khoom muaj peev xwm. Piv txwv li, mainboards rau cov neeg siv khoom siv hluav taws xob feem ntau siv kev sib xyaw ua ke ntawm FR-4 substrates, electrolytic tooj liab ntawv ci, thiab kua dej photosensitive number case. Automotive electronics, conversely, yuav tsum tau siab -Tg (iav hloov kub siab tshaj los yog sib npaug rau 170 degree) substrates thiab dov tooj liab ntawv ci los tiv thaiv thermal cycling kev ntsuam xyuas xws li -40℃mus rau 150℃. Cov ntawv luam tawm yooj yim (FPCs), lub sijhawm no, ua qhov tseem ceeb ntawm kev siv PI zaj duab xis thiab ultra-thin tooj liab ntawv ci los pab txhawb kev ua haujlwm zoo ntawm kev khoov.
