Ubuyobozi Bwiza Bucapishijwe Inzira Yumuzingi PCB

Ubushobozi bwa PCB (Inteko ya PCB)

Ibyerekeye

PCB yateye imbere kuva kumurongo umwe kugeza kumpande ebyiri, ibice byinshi kandi byoroshye, kandi ihora itera imbere mubyerekezo bisobanutse neza, ubwinshi bwinshi kandi bwizewe.Gukomeza kugabanya ingano, kugabanya ikiguzi, no kunoza imikorere bizatuma ikibaho cyumuzingo cyacapwe gikomeza kugira imbaraga zikomeye mugutezimbere ibicuruzwa bya elegitoroniki mugihe kizaza.Mu bihe biri imbere, iterambere ryiterambere ryimyandikire yumuzunguruko wanditse ni ugutezimbere mu cyerekezo cyinshi, cyuzuye, aperture nto, insinga ntoya, ikibuga gito, kwizerwa cyane, ibyiciro byinshi, kwanduza umuvuduko mwinshi, uburemere bworoshye na inoze.

Intambwe zirambuye nuburyo bwo kwirinda umusaruro wa PCB

1. Igishushanyo
Mbere yuko inzira yo gukora itangira, PCB igomba gutegurwa / imiterere nu mukoresha wa CAD ukurikije igishushanyo mbonera cyakazi.Igishushanyo mbonera kimaze kurangira, urutonde rwinyandiko rutangwa kubakora PCB.Amadosiye ya Gerber ashyirwa mubyangombwa, bikubiyemo iboneza-by-ibice, amadosiye ya drillthrough, gutoranya no gushyira amakuru, hamwe no gutangaza inyandiko.Gutunganya ibyapa, gutanga amabwiriza yo gutunganya aringirakamaro mubikorwa, PCB ibisobanuro byose, ibipimo no kwihanganira.

2. Kwitegura mbere yo gukora
Inzu ya PCB imaze kwakira dosiye yububiko, barashobora gutangira gukora gahunda yo gukora hamwe nibikorwa byubuhanzi.Gukora ibisobanuro bizagena gahunda mugutondekanya ibintu nkubwoko bwibintu, kurangiza hejuru, isahani, umurongo wibikorwa byakazi, inzira ikurikirana, nibindi byinshi.Mubyongeyeho, urutonde rwibikorwa byumubiri birashobora gushirwaho binyuze mumashusho ya firime.Ibikorwa byubuhanzi bizaba birimo ibice byose bya PCB kimwe nubuhanzi bwa saleermask hamwe no gushiraho ikimenyetso.

3. Gutegura ibikoresho
Ibisobanuro bya PCB bisabwa nuwabishizeho agena ubwoko bwibintu, uburebure bwibanze nuburemere bwumuringa bikoreshwa mugutangira gutegura ibikoresho.Uruhande rumwe kandi rufite impande ebyiri zikomeye PCBs ntisaba gutunganyirizwa imbere imbere hanyuma ukajya mubikorwa byo gucukura.Niba PCB ifite ibice byinshi, imyiteguro isa nkiyi izakorwa, ariko muburyo bwimiterere yimbere, ubusanzwe iba yoroheje cyane kandi irashobora kubakwa kugeza mubyimbye byanyuma (stackup).
Ingano yumusaruro rusange ni 18 ″ x24 ″, ariko ubunini ubwo aribwo bwose burashobora gukoreshwa igihe cyose buri mubushobozi bwo gukora PCB.

4. PCB igizwe na PCB gusa - gutunganya imbere
Nyuma yubunini bukwiye, ubwoko bwibintu, uburebure bwibanze hamwe nuburemere bwumuringa murwego rwimbere byateguwe, byoherejwe gucukura umwobo wakozwe hanyuma ugacapura.Impande zombi zibi bice zometseho amafoto.Huza impande ukoresheje ibishushanyo mbonera by'imbere hamwe n'ibikoresho by'ibikoresho, hanyuma werekane buri ruhande kumucyo UV urambuye optique ya optique yibiranga nibiranga byerekanwe kuri urwo rwego.Umucyo UV ugwa kumafoto uhuza imiti hejuru yumuringa, naho imiti isigaye idakurwa ikurwa mubwogero bukura.

Intambwe ikurikiraho ni ugukuraho umuringa wagaragaye binyuze muburyo bwo gutobora.Ibi bisiga umuringa wihishe munsi yumurongo wa fotore.Mugihe cyo guswera, byombi kwibanda kuri etchant nigihe cyo kumurika nibintu byingenzi.Kurwanya noneho biramburwa, hasigara ibimenyetso nibiranga kurwego rwimbere.

Abatanga PCB benshi bakoresha sisitemu yo kugenzura optique yo kugenzura kugirango igenzure ibice na post-etch kugirango bongere ibikoresho bya lamination.

5. PCB nyinshi PCB gusa - Laminate

Ikibanza cyateganijwe mbere yimikorere gishyirwaho mugihe cyo gushushanya.Igikorwa cyo kumurika gikorerwa mucyumba gisukuye gifite icyumba cyimbere cyuzuye, prereg, foil y'umuringa, amasahani yo gukanda, pin, icyuma kitagira umwanda hamwe nicyapa cyinyuma.Buri kinyamakuru gishobora kwakira imbaho ​​4 kugeza kuri 6 kuri buri gufungura kanda, bitewe nubunini bwa PCB yarangiye.Urugero rwibibaho 4 byubatswe byaba: platine, icyuma gitandukanya ibyuma, icyuma cyumuringa (layer ya 4), prereg, intangiriro ya 3-2, prereg, file yumuringa, hanyuma usubiremo.Nyuma ya 4 kugeza kuri 6 PCB ziteranijwe, shyira hejuru ya platine hanyuma uyishyire mumashini yamurika.Imashini irazamuka igera kuri kontour hanyuma igashyiraho igitutu kugeza resin ishonga, icyo gihe prereg igatemba, igahuza ibice hamwe, hamwe nabanyamakuru bakonje.Iyo ikuwe hanze kandi yiteguye

6. Gucukura
Igikorwa cyo gucukura gikozwe na CNC igenzurwa na mashini yo gucukura sitasiyo nyinshi ikoresha spindle ndende ya RPM hamwe na carbide drill bit yagenewe gucukura PCB.Viyasi isanzwe irashobora kuba ntoya nka 0.006 ″ kugeza 0.008 ″ yacukuwe kumuvuduko uri hejuru ya 100K RPM.

Igikorwa cyo gucukura gikora urukuta rusukuye, rworoshye rudashobora kwangiza ibice byimbere, ariko gucukura bitanga inzira yo guhuza ibice byimbere nyuma yo kubisiga, kandi umwobo utanyuze urangirira kuba murugo uciyemo umwobo.
Ibyobo bidafite isahani mubisanzwe biracukurwa nkigikorwa cya kabiri.

7. Isahani y'umuringa
Electroplating ikoreshwa cyane mubikorwa bya PCB aho bisabwa binyuze mu mwobo.Intego ni ukubika igice cyumuringa kuri substrate yuyobora binyuze murukurikirane rwimiti ivura imiti, hanyuma hakoreshejwe uburyo bwa electroplating uburyo bwo kongera umubyimba wurwego rwumuringa mubyerekezo byihariye, mubisanzwe mil 1 cyangwa irenga.

8. Kuvura hanze
Gutunganya ibice byo hanze mubyukuri birasa nuburyo byasobanuwe mbere murwego rwimbere.Impande zombi zo hejuru no hepfo zometseho amafoto.Huza impande ukoresheje ibihangano byo hanze hamwe nu mwobo wibikoresho, hanyuma ugaragaze buri ruhande kumucyo UV kugirango ubone ibisobanuro byiza bya optique yibimenyetso nibiranga.Umucyo UV ugwa kumafoto uhuza imiti hejuru yumuringa, hanyuma imiti isigaye idakurwa ikurwa mubwogero bukura.Intambwe ikurikiraho ni ugukuraho umuringa wagaragaye binyuze muburyo bwo gutobora.Ibi bisiga umuringa wihishe munsi yumurongo wa fotore.Kurwanya noneho biramburwa, hasigara ibimenyetso nibiranga kurwego rwo hanze.Inenge yo hanze irashobora kuboneka mbere yo kugurisha mask ukoresheje igenzura ryikora ryikora.

9. Solder paste
Porogaramu ya Solder isa niyimbere ninyuma yimikorere.Itandukaniro nyamukuru nugukoresha mask yifoto yerekana amashusho aho gufotora hejuru yubuso bwibikorwa.Noneho koresha ibihangano kugirango ufate amashusho hejuru no hepfo.Nyuma yo kwerekanwa, mask yakuweho ahantu hafashwe amashusho.Ikigamijwe ni ugushyira ahagaragara gusa ibice bizashyirwa kandi bigurishwa.Mask nayo igabanya ubuso bwa PCB ahantu hagaragara.

10. Kuvura hejuru

Hano hari amahitamo menshi yo kurangiza kurangiza.Zahabu, ifeza, OSP, umugurisha udafite isasu, uwagurishije arimo gurş, nibindi byose bifite agaciro, ariko mubyukuri bitetse kubishushanyo mbonera.Zahabu na feza bikoreshwa na electroplating, mugihe ibicuruzwa bidafite isasu kandi birimo isasu bikoreshwa mu buryo butambitse nugurisha ikirere gishyushye.

11. Amazina
PCB nyinshi zirinzwe kubimenyetso hejuru yabyo.Ibimenyetso bikoreshwa cyane mubikorwa byo guterana kandi birimo ingero nkibimenyetso byerekana ibimenyetso bya polarite.Ibindi bimenyetso birashobora kuba byoroshye nkigice cyo kumenyekanisha igice cyangwa kode yitariki yo gukora.

12. Sub-board
PCBs ikorerwa mumashanyarazi yuzuye agomba kwimurwa mubikorwa byabo.PCBs nyinshi zashyizweho muburyo bwo kunoza imikorere yinteko.Hashobora kubaho umubare utagira ingano wiyi array.Ntushobora gusobanura.

Imirongo myinshi ni umwirondoro usya ku ruganda rwa CNC ukoresheje ibikoresho bya karbide cyangwa amanota ukoresheje ibikoresho bya diyama bisize.Ubwo buryo bwombi bufite ishingiro, kandi guhitamo uburyo mubisanzwe bigenwa nitsinda ryinteko, ubusanzwe ryemeza umurongo wubatswe hakiri kare.

13. Ikizamini
Abakora PCB mubisanzwe bakoresha iguruka cyangwa uburiri bwikizamini cyo gupima imisumari.Uburyo bwikizamini bugenwa nubunini bwibicuruzwa na / cyangwa ibikoresho bihari
