Yog koj xav li cas tiag Printed Circuit Boards (PCBs) yog thiab lawv yuav ua li cas, ces koj tsis nyob ib leeg.Ntau tus neeg muaj kev nkag siab tsis meej ntawm "Circuit Boards", tab sis tiag tiag tsis yog cov kws tshaj lij thaum nws tuaj yeem piav qhia seb lub Printed Circuit Board yog dab tsi.PCBs feem ntau yog siv los txhawb thiab txuas hluav taws xob txuas cov khoom siv hluav taws xob txuas rau lub rooj tsavxwm.Qee qhov piv txwv ntawm cov khoom siv hluav taws xob rau PCB yog capacitors thiab resistors.Cov no thiab lwm yam khoom siv hluav taws xob sib txuas los ntawm cov kab hluav taws xob, cov kab hluav taws xob lossis cov kab teeb liab uas tau etched los ntawm cov nplooj ntawv tooj liab uas tau laminated mus rau cov tsis muaj hluav taws xob substrate.Thaum lub rooj tsavxwm muaj cov kab hluav taws xob thiab tsis muaj kev coj ua, cov laug cam qee zaum hu ua Printed Wiring Board (PWB).Thaum lub rooj tsavxwm muaj cov xaim hluav taws xob thiab cov khoom siv hluav taws xob sib txuas, Lub Rooj Tswjhwm Saib Circuit Court tam sim no hu ua Printed Circuit Assembly (PCA) lossis Printed Circuit Board Assembly (PCBA).

Printed Circuit Boards feem ntau pheej yig, tab sis tseem muaj kev ntseeg siab heev.Tus nqi pib yog siab vim tias qhov kev siv dag zog yuav tsum tau siv sijhawm ntau thiab cov peev txheej, tab sis PCBs tseem yog tus nqi ntau dua thiab sai dua los tsim cov khoom ntim ntau.Ntau qhov kev lag luam PCB Tsim, kev tswj kom zoo, thiab cov qauv sib dhos tau teeb tsa los ntawm Association Connecting Electronics Industries (IPC) lub koom haum.

Thaum tsim cov PCBs, feem ntau ntawm cov ntawv luam tawm yog tsim los ntawm kev sib txuas cov txheej tooj liab hla lub substrate, qee zaum ntawm ob sab, uas tsim ib qho dawb paug PCB.Tom qab ntawd, qhov tsis xav tau tooj liab raug tshem tawm tom qab lub npog ntsej muag ib ntus tau siv los ntawm etching.Qhov no tsuas yog tso cov kab tooj liab uas xav tau nyob hauv PCB.Nyob ntawm seb qhov ntim ntawm qhov ntau lawm yog rau Cov Qauv / Qauv ntau npaum li cas lossis qhov ntim ntau lawm, muaj cov txheej txheem ntawm ntau yam electroplating, uas yog cov txheej txheem nyuaj uas ntxiv cov kab lossis ib txheej tooj liab nyias ntawm cov substrate mus rau qhov liab qab substrate.

Muaj ntau txoj hauv kev rau kev rho tawm (lossis tshem tawm cov tsis xav tau tooj liab ntawm lub rooj tsavxwm) thaum tsim cov PCBs.Txoj kev lag luam tseem ceeb ntawm cov khoom ntim ntau yog silk screen luam ntawv thiab cov duab thaij duab (feem ntau yog siv thaum kab dav dav zoo).Thaum lub ntim ntau lawm yog me me, txoj hauv kev tseem ceeb ntawm kev siv yog laser luam tawm tiv thaiv, luam tawm mus rau pob tshab zaj duab xis, laser resist ablation, thiab siv CNC-mills.Cov txheej txheem feem ntau yog silk screen printing, photoengraving, thiab milling.Txawm li cas los xij, muaj cov txheej txheem uas tseem muaj nyob uas feem ntau siv rau multilayer circuit boards vim nws yooj yim rau plating-dhau ntawm lub qhov, uas yog hu ua "Addictive" los yog "Semi-Addictive".
