Cov txheej txheem ntau lawm ntawm cov laug cam feem ntau yog ua los ntawm cov txheej txheej sab hauv ua ntej, tom qab ntawd los ntawm kev luam ntawv thiab etching txoj kev los ua ib sab los yog ob sab substrate, thiab mus rau hauv cov txheej txheem ntawm, thiab tom qab ntawd los ntawm cua sov, nias thiab sib txuas, Raws li rau cov tom ntej drilling yog tib yam li ob txoj kev plating los ntawm lub qhov.
1. Ua ntej tshaj plaws, FR4 Circuit Board yuav tsum tau tsim ua ntej.Tom qab plating lub perforated tooj liab nyob rau hauv lub substrate, lub qhov yog sau nrog resin thiab cov nto kab yog tsim los ntawm subtractive etching.Cov kauj ruam no yog tib yam li FR4 lub rooj tsavxwm tshwj tsis yog rau kev sau cov perforations nrog cob.
2. Lub photopolymer epoxy resin yog siv los ua thawj txheej ntawm rwb thaiv tsev FV1, thiab tom qab ziab, photomask yog siv rau cov kauj ruam raug, thiab tom qab raug, hnyav yog siv los tsim lub qhov qis ntawm peg qhov.Hardening ntawm cov resin yog nqa tawm tom qab qhib lub qhov.
3. Lub epoxy resin nto yog roughened los ntawm permanganic acid etching, thiab tom qab etching, ib txheej ntawm tooj liab yog tsim nyob rau saum npoo los ntawm electroless tooj liab plating rau cov tom ntej tooj liab plating kauj ruam.Tom qab plating, tooj liab txheej txheej yog tsim thiab lub hauv paus txheej yog tsim los ntawm subtractive etching.
4. Coated nrog ib txheej thib ob ntawm rwb thaiv tsev, siv tib yam kev nthuav qhia cov kauj ruam los tsim ib lub qhov ntsia hlau hauv qab lub qhov.
5. Yog tias xav tau perforation, koj tuaj yeem siv qhov drilling ntawm qhov los tsim cov perforations tom qab tsim cov tooj liab electroplating etching los ua cov hlau.
nyob rau hauv lub txheej txheej sab nrauv ntawm lub rooj tsav xwm Circuit Court coated nrog cov xim pleev xim, thiab siv txoj kev nthuav dav nthuav tawm los nthuav tawm qhov kev sib cuag.
6. Yog tias cov khaubncaws sab nraud povtseg nce ntxiv, tsuas yog rov ua cov kauj ruam saum toj no.Yog tias muaj cov txheej txheem ntxiv ntawm ob sab, txheej txheej rwb thaiv tsev yuav tsum tau coated ntawm ob sab ntawm lub hauv paus txheej, tab sis cov txheej txheem plating tuaj yeem nqa tawm ntawm ob sab tib lub sijhawm.
