Cov yam ntxwv ntawm PCB qauv
1. Solderresistant number case (Solderresistant/SolderMask): Tsis yog txhua qhov chaw tooj liab yuav tsum tau noj cov khoom tin, yog li thaj chaw uas tsis yog-tin-noj yuav raug luam tawm nrog ib txheej ntawm cov khoom (feem ntau yog epoxy resin) uas cais cov tooj liab ntawm cov khoom noj tin mus rau zam tsis- soldering.Muaj ib qho luv luv ntawm cov kab tinned.Raws li cov txheej txheem sib txawv, nws muab faib ua roj ntsuab, roj liab thiab xiav roj.
2. Dielectric txheej (Dielectric): Nws yog siv los tswj cov rwb thaiv tsev ntawm cov kab thiab txheej, feem ntau hu ua substrate.
3. Kev kho deg (SurtaceFinish): Txij li cov tooj liab nto tau yooj yim oxidized nyob rau hauv ib puag ncig, nws tsis tuaj yeem tinned (tsis zoo solderability), yog li cov tooj liab nto yuav tsum tau tinned yuav tiv thaiv.Cov kev tiv thaiv muaj xws li HASL, ENIG, Immersion Silver, Immersion TIn, thiab organic solder preservative (OSP).Txhua txoj kev muaj nws qhov zoo thiab qhov tsis zoo, sib sau ua ke hu ua kev kho saum npoo.
