IC substrates ua qhov sib txuas ntawm IC nti (s) thiab PCB los ntawm kev sib txuas network ntawm kab thiab qhov. IC substrates txhawb cov haujlwm tseem ceeb nrog rau kev txhawb nqa thiab kev tiv thaiv, tiv thaiv tshav kub, thiab teeb liab thiab faib hluav taws xob.
IC substrates sawv cev rau qib siab ntawm miniaturization nyob rau hauv PCB kev tsim khoom thiab sib koom ntau yam zoo sib xws nrog kev tsim hluav taws xob semiconductor.
IC substrate tau tsim nrog kev loj hlob ntawm cov hom tshiab ntawm ICs zoo li BGA (pob sib kis hauv pob) thiab CSP (chip scale pob) uas hu rau cov nqa khoom tshiab ntawm pob. Raws li ib hom ntawm qib siab tshaj PCB (Luam tawm Circuit Board), IC substrate PCB tau tawg nyob rau hauv ob qho tag nrho cov chaw thiab daim ntawv thov ua ke nrog txhua txheej HDI PCB thiab flex-rigid PCB, tam sim no dav thov hauv kev sib txuas xov tooj thiab hluav taws xob hloov kho.
