Printed Circuit Boards (PCBs) yog * tsis * semiconductors; es, lawv nyob txawv theem nyob rau hauv lub electronics kev lag luam mov saw. Lub PCB ua haujlwm raws li cov qauv kev txhawb nqa lub cev thiab cov khoom siv hluav taws xob sib txuas rau cov khoom siv hluav taws xob, hos semiconductors yog cov khoom siv tseem ceeb siv los tsim cov chips.
Lub rooj tsavxwm luam tawm yog lub substrate tsim los txhawb thiab sib cuam tshuam cov khoom siv hluav taws xob; nws feem ntau muaj cov ntaub ntawv insulating (xws li fiberglass lossis yas) thiab cov khoom siv hluav taws xob (xws li tooj liab ntawv ci). Nws lub luag haujlwm tseem ceeb yog muab kev txhawb nqa txhua yam thiab kev sib txuas hluav taws xob, es tsis yog nthuav tawm cov khoom siv hluav taws xob tswj tau -insulative yam ntxwv ntawm semiconductors.
Lub semiconductor yog ib yam khoom uas muaj hluav taws xob conductivity theem nyob nruab nrab ntawm tus neeg xyuas pib thiab ib qho insulator; nws cov khoom siv hluav taws xob tuaj yeem tswj tau los ntawm cov txheej txheem xws li doping lossis kev siv hluav taws xob. Cov khoom siv semiconductor zoo ib yam-xws li silicon, germanium, thiab gallium arsenide- tau siv dav hauv cov khoom siv hluav taws xob xws li transistors, diodes, thiab kev sib xyaw ua ke.
Txawm hais tias ob qho tib si luam tawm Circuit boards thiab semiconductors yog cov khoom tseem ceeb ntawm kev lag luam hluav taws xob, lawv txawv heev ntawm lawv cov haujlwm thiab kev siv. PCBs feem ntau ua haujlwm rau mount thiab interconnect electronic Cheebtsam, whereas semiconductors tsim cov ntaub ntawv tseem ceeb los ntawm cov khoom no yog fabricated. Cov txheej txheem tsim khoom rau PCBs suav nrog cov kauj ruam xws li etching, drilling, thiab plating, whereas semiconductor manufacturing entails complex processes such as photolithography, doping, and thin{2}}film deposition.
