Mubikorwa bya PCB, inzira yo kuvura hejuru nintambwe ikomeye. Ntabwo bigira ingaruka gusa isura ya PCB gusa, ariko nayo ifitanye isano itaziguye n'imikorere, kwizerwa no kuramba kwa PCB. Inzira yo kuvura hejuru irashobora gutanga urwego rukingira kugirango wirinde ruswa yumuringa, kuzamura imikorere yo kugurisha, kandi utange imitungo myiza yamashanyarazi. Ibikurikira ni isesengura ryibikorwa byinshi bikunze kuvura ibintu bya PCB.
一 .Hasl (ikirere gishyushye cyoroshye)
Ihangane rishyushye (Hasl) ni tekinoroji ya PCB gakondo ya PCB ikorera PCB muri colten tin / kuyobora alloy hanyuma ugakoresha umwuka ushushe kugirango "utera" indege imwe. Inzira ya Hasl ni ikiguzi gito kandi kibereye gukora ibicuruzwa bitandukanye bya PCB, ariko birashobora kugira ibibazo birimo amakaramu no mu mbuga zidahuye.
二 .nig (chimique nikel)
Icyamamare cya electroless nackel (enig) nigikorwa cyo gushinja ickeli na zahabu hejuru ya pcb. Ubwa mbere, ubuso bwumuringa burasukuwe kandi bugakora, noneho igipimo gito cya nikel kishyirwa mubikorwa byo gusimbuza imiti, hanyuma hashyizweho igice cya zahabu cyashyizwe hejuru ya Nikeli. Igikorwa cya enig gitanga icyerekezo cyiza no kwambara kurwanya kandi bikwiranye nibisabwa byibaze, ariko ikiguzi ni kinini.
三, zahabu ya chimique
Imiti ya zahabu yometse igice cyoroshye cya zahabu hejuru ya PCB. Iyi nzira ikunze gukoreshwa mubisabwa bidasaba kugurisha umugurisha, nka radiyo (RF) na Microwave, kuko zahabu itanga inzira nziza kandi irwanya imyanda. Zahabu ya chimique igura munsi ya enig, ariko ntabwo irwanya ikananga nka enig.
四, OSP (film yo gukingira kama)
Filime yo gukingira kama (OSP) ni inzira igira film organic on filnge yumuringa kugirango wirinde umuringa ukomoka. OSP ifite inzira yoroshye kandi ikiguzi gito, ariko uburinzi itanga isake kandi ibereye kubika igihe no gukoresha PCB.
五, zahabu ikomeye
Zahabu ikomeye nigikorwa cyo kubitsa igice cya zahabu cya zahabu kuri PCB hejuru ya electraplating. Zahabu ikomeye irambara cyane kuruta zahabu yimiti kandi ibereye guhuza bisaba gucomeka kenshi no gucomeka cyangwa gucomeka cyangwa pcbs ikoreshwa mubidukikije bikaze. Zahabu igura ibiciro birenze zahabu yimiti ariko itanga uburinzi bwiza.
六, Ifeza
Kwibiza ifeza ni inzira yo kubishyira hejuru ya feza hejuru ya PCB. Ifeza ifite imyitwarire myiza nuburyo bwiza, bigatuma porogaramu zigaragara kandi zishaje. Igiciro cyo kwibiza inzira ya feza giciriritse, ariko urwego rwa feza rusabwe byoroshye kandi rusaba ingamba zo kurinda.
七, kwibiza amabati
Kwibiza amabati nigikorwa cyo kubishyira hejuru ya Tin hejuru ya PCB. Igice cya TIn gitanga imitungo myiza yo kugurisha hamwe no kurwanya ruswa. Kwibiza inzira ya TIn bihendutse, ariko urwego rwa TIn rurabyimba byoroshye kandi mubisanzwe rusaba urwego rukingira.
八, kunyura hasi
Hasl-yubusa ni rohs-yubahiriza inzira ikoresha amabati / ifeza / umuringa Inzira-yubusa ituje itanga imikorere isa nibisabwa nibidukikije.
Hariho inzira zitandukanye zo kuvura hejuru, kandi buri nzira ifite ibyiza byihariye nibisabwa. Guhitamo inzira yo kuvura hejuru bisaba gusuzuma ibidukikije, ibisabwa, ibisabwa, ingengo yimari nibidukikije bya PCB. Hamwe no guteza imbere ikoranabuhanga rya elegitoronike, inzira nshya yo kuvura hejuru ikomeje kugaragara, itanga abakora pcb hamwe nuburyo bwinshi bwo guhitamo kugirango bahize isoko.
