Lub thickness ntawm kub-plated PCB feem ntau yog hais txog qhov tuab ntawm cov nyiaj kub, tsis yog lub thickness ntawm pcb substrate. Muaj cov sib txawv ntawm cov tuab ntawm cov txheej kub txheej hauv qab cov txheej txheem sib txawv thiab cov xwm txheej thov kev xaiv:
Cov tuab tuab li
Zoo tib yam pcb: 0.05-0.1 μ m m (ua raws li IPC-4552A tus qauv)
Siab ntauCircuit Court: 0.025-0.05 μ m (txo cov paib teeb liab)
Tub rog / Aerospace: 0.075 ~ 0.125 μ m (txhim kho corrosion tsis kam)
Tshwj Xeeb Cov Txheej Txheem Kho
Cov Kub Hluav Taws Xob: nce mus txog 0.5 ~ 5 μ m (yuav tsum muaj cov khoom siv hluav taws xob txhawb nqa)
Kev Siv Tshuaj Tso Cai Kub: Cov tuab ntawm 0.08 ~ 0.1 μ m
Kev ntsuas tus nqi thiab kev ua tau zoo
For every 0.01 μ m increase in the gold layer, the cost of the single board increases by approximately ¥ 0.03~0.05 (based on an Au price of 300 yuan/g). Excessive thickness (>0.15 μ m) tuaj yeem ua rau kom muaj kev nce ntxiv ntawm qhov av uas muaj ntau thiab ua rau cov txiv kab ntxwv tev tev.
Lub thickness ntawm cov kub tso zis tso rau ntawm PCB Circuit Coffic boards feem ntau yog 1-5 microns. Cov txheej txheem no tau ua tiav los ntawm Electroplating, uas tuaj yeem txhim kho kev coj ua (txo kev sib chwv), thiab soldance solder sib koom ua ke lub zog). Thickness ncaj qha cuam tshuam kev ntseeg tau, piv txwv li: Cov duab hluav taws xob tsim nyog rau cov khoom siv hluav taws xob ntau (xws li siv cov khoom siv tsis zoo rau cov neeg siv khoom tsawg. Lub sij hawm elctropating tuaj yeem tswj cov tuab, thiab tus nqi thiab yuav tsum tau sib npaug raws li cov lus qhia kev sib txuas lus xws li cov khoom sib txuas lus thiab khoom siv kho mob.
Cov kev xav tau rau kub plating (electroplated kub, electroplated kub) ntawm Circuit Court laug cam yog:
Thaum siv los ua cov kev kho sab saum toj Thov saib cov lus qhia rau cov kub kub.
Tam sim no, electroplating kub yog tsis tshua muaj siv los ua cov txheej txheem kev kho mob saum npoo av tau txo qis kub (uas tuaj yeem yooj yim ua rau kub ntev tsis yog tinned).
Tam sim no, cov kub electroplated feem ntau siv rau cov ntiv tes ntiv tes (vim nws cov ntiv tes zoo (ua kom zoo rau cov ntiv tes kub (ua kom muaj kev nkag mus thiab rho tawm). Cov kev yuav tsum tau ua yog qhov tuab ntawm 15U, uas yog ntseeg tau thiab lav zoo (uas yog ntawm cov khoom lag luam siab thiab cov khoom lag luam loj thiab cov khoom lag luam feem ntau yuav tsum tau cov tuab no).
Kuj tseem muaj cov hom phiaj tshwj xeeb thiab kev siv ntawm lwm cov tuab tuab, piv txwv li: Aerospace thiab ntseeg tau yam tsis tau txais kev xav tau ntawm 50U. Rau cov neeg uas tsuas yog caum cov nqi qis-ntev, tsuav lawv tuaj yeem siv, cov ntawv nco, cov npav network, thiab lwm yam.
