About
PCB yakagadzira kubva kune imwe-layer kuenda kune kaviri-mativi, akawanda-layer uye anochinjika mabhodhi, uye ari kuramba achikura munzira yekwakanyanya kurongeka, kusimba kwepamusoro uye kuvimbika kwakanyanya.Kuramba kuchidzikira saizi, kuderedza mutengo, uye kuvandudza mashandiro kuchaita kuti bhodhi redunhu rakadhindwa richiri kuchengetedza simba rakasimba mukuvandudza zvigadzirwa zvemagetsi mune ramangwana.Mune ramangwana, maitiro ekuvandudza akadhindwa edhisheni bhodhi kugadzira tekinoroji ndeyekukudziridza munzira yekukwira kwepamusoro, kurongeka kwepamusoro, kuvhura diki, waya yakatetepa, diki diki, kuvimbika kwakanyanya, akawanda-layer, kukurumidza-kumhanya, huremu huremu uye. chimiro chitete.
Yakadzama matanho uye ekudzivirira kwePCB kugadzirwa
1. Dhizaini
Nzira yekugadzira isati yatanga, iyo PCB inoda kugadzirwa / kurongeka neCAD opareta zvichibva pane yebasa redunhu schematic.Kana iyo dhizaini yapera, seti yezvinyorwa inopihwa kumugadziri wePCB.Mafaira eGerber anosanganisirwa mune zvinyorwa, izvo zvinosanganisira layer-by-layer configuration, drillthrough mafaira, tora uye isa data, uye zvinyorwa zvinyorwa.Kugadziridza maprints, kupa mirairo yekugadzirisa yakakosha pakugadzira, ese PCB maratidziro, zviyero uye kushivirira.
2. Kugadzirira kusati kwagadzirwa
Kana iyo PCB imba yagamuchira faira remugadziri, vanogona kutanga kugadzira chirongwa chekugadzira uye artwork package.Madimikira ekugadzira anozotarisa hurongwa nekunyora zvinhu zvakaita semhando yemhando, kupedzisa kwepamusoro, plating, hurongwa hwemapaneru ebasa, process routing, nezvimwe.Mukuwedzera, seti yezvigadzirwa zvemuviri zvinogona kugadzirwa kuburikidza nemugadziri wemafirimu.Artwork ichasanganisira ese akaturikidzana ePCB pamwe nehunyanzvi hwekugadzira soldermask uye temu yekumaka.
3. Kugadzirira zvinhu
Iyo PCB yakatarwa inodiwa nemugadziri inosarudza rudzi rwezvinhu, ukobvu hwepakati uye huremu hwemhangura hunoshandiswa kutanga kugadzirira zvinhu.Single-sided uye kaviri-sided rigid PCBs haidi chero yemukati layer yekugadzirisa uye inoenda yakananga kune yekuchera maitiro.Kana iyo PCB ine-multi-layered, gadziriro yezvinyorwa zvakafanana ichaitwa, asi nenzira yemukati, iyo inowanzova yakatetepa uye inogona kuvakwa kusvika kune yakatemerwa yekupedzisira ukobvu (stackup).
Saizi yekugadzira yakajairika ndeye 18 ″ x24 ″, asi chero saizi inogona kushandiswa chero iri mukati mePCB kugadzira kugona.
4. Multilayer PCB chete - inner layer processing
Mushure mezviyero zvakafanira, rudzi rwezvinhu, ukobvu hwepakati uye huremu hwemhangura hwemukati hwemukati hwakagadzirirwa, inotumirwa kunodhiza maburi emuchina wozodhinda.Mativi ese maviri ematanho aya akaputirwa nephotoresist.Rongedza mativi uchishandisa yemukati dhizaini uye maburi emidziyo, wobva wafumura divi rega rega kuUV mwenje unotsanangura iyo yekuona isina kunaka yemateki uye maficha akatsanangurwa kune iyo layer.Chiedza cheUV chinowira paphotoresist chinosungirira kemikari kunzvimbo yemhangura, uye kemikari yakasara isina kuvhurwa inobviswa mubhavhu rinokura.
Nhanho inotevera ndeyekubvisa iyo yakafumurwa mhangura kuburikidza ne etching process.Izvi zvinosiya zvironda zvemhangura zvakavigwa pasi pe photoresist layer.Munguva ye etching process, zvese kusungirirwa kweiyo etchant uye nguva yekuratidzwa ndiyo yakakosha paramita.Iyo yekupikisa inobva yabviswa, ichisiya mavara uye maitiro pane yemukati layer.
Vazhinji vatengesi vePCB vanoshandisa otomatiki optical yekuongorora masisitimu kuti vatarise maseru uye post-etch punches kuti ikwidze maburi emidziyo yekushandisa.
5. Multilayer PCB chete - Laminate
Iyo yakatemerwa stack yemaitiro inotangwa panguva yekugadzira maitiro.Iyo lamination process inoitwa munzvimbo yakachena yekamuri nharaunda ine yakazara yemukati layer, prepreg, copper foil, press mahwendefa, mapini, Stainless simbi spacers uye backing plates.Imwe neimwe inodhinda stack inogona kugarisa 4 kusvika 6 mabhodhi pakuvhurwa kwekudhinda, zvichienderana nekukora kwePCB yapera.Muenzaniso we4-layer board stackup ingave: platen, separator yesimbi, foil yemhangura (4th layer), prepreg, core 3-2 layer, prepreg, foil yemhangura, uye dzokorora.Mushure mekunge 4 kusvika ku6 maPCB aungana, chengetedza platen yepamusoro uye woiisa mumuchina welamination.Muchina wekudhinda unokwira kusvika kune contours uye unoshandisa kumanikidza kusvikira resin yanyunguduka, panguva iyo prepreg inoyerera, ichibatanidza zvidimbu pamwe chete, uye mushini unotonhora.Pakubudiswa uye kugadzirira
6. Kuchera
Kuchera kunoitwa neCNC-inodzorwa multi-station yekuchera muchina inoshandisa yakakwirira RPM spindle uye carbide drill bit yakagadzirirwa PCB kuchera.Typical vias anogona kuva diki se 0.006 ″ kusvika 0.008 ″ akadhirowa nekumhanya pamusoro 100K RPM.
Nzira yekuchera inogadzira mudhuri wegomba wakachena, wakatsetseka usingakanganise mativi emukati, asi kuchera kunopa nzira yekubatana kwemukati mezvikamu mushure mekuputirwa, uye iyo isiri-kuburikidza negomba inoguma yave kumba kune kuburikidza-gomba zvikamu.
Makomba asina kuputirwa anowanzo dhiriwa sechivhitivhiti chechipiri.
7. Copper plating
Electroplating inoshandiswa zvakanyanya mukugadzirwa kwePCB uko kwakaputirwa nemakomba kunodiwa.Chinangwa ndechekuisa chidimbu chemhangura pane conductive substrate kuburikidza nenhevedzano yemakemikari marapirwo, uyezve kuburikidza neanotevera nzira dze electroplating yekuwedzera ukobvu hwemhangura kune yakasarudzika dhizaini ukobvu, kazhinji miriyoni imwe kana kupfuura.
8. Outer layer kurapwa
Iyo yekunze dhizaini yekugadzirisa inongofanana neiyo nzira yakambotsanangurwa yemukati yemukati.Mativi ese ari maviri epamusoro uye epasi akafukidzwa nephotoresist.Rongedza mativi uchishandisa artwork yekunze uye maburi emidziyo, wobva wafumura divi rega rega kuUV mwenje kudonongodza maitiro asina kunaka ematehwe uye maficha.Chiedza cheUV chinowira pane photoresist chinosungirira kemikari kunzvimbo yemhangura, uye kemikari yakasara isina kuburitswa inobviswa mubhavhu rinokura.Nhanho inotevera ndeyekubvisa iyo yakafumurwa mhangura kuburikidza ne etching process.Izvi zvinosiya zvironda zvemhangura zvakavigwa pasi pe photoresist layer.Iyo yekupikisa inobva yabviswa, ichisiya mavara uye maitiro pane yekunze layer.Outer layer hurema hunogona kuwanikwa pamberi pe solder mask uchishandisa otomatiki optical ongororo.
9. Solder paste
Solder mask application yakafanana neyemukati uye yekunze layer process.Musiyano mukuru ndewekushandiswa kwemasikisi inogoneka pachinzvimbo chephotoresist pamusoro pese pese penzvimbo yekugadzira.Wobva washandisa dhizaini kuti utore mifananidzo iri pamusoro nepamusoro.Mushure mekuratidzwa, mask inobviswa munzvimbo ine mufananidzo.Chinangwa ndechekufumura chete nzvimbo iyo zvikamu zvichaiswa uye kutengeswa.Iyo maski zvakare inodzikamisa kupera kwepamusoro kwePCB kunzvimbo dzakafumurwa.
10. Kurapa kwepamusoro
Pane zvakawanda zvingasarudzwa zvekupedzisira kwepamusoro pekupedzisira.Ndarama, sirivheri, OSP, lead-free solder, lead-container solder, etc. Zvose izvi zvinoshanda, asi bhodhora pasi kune zvinodiwa zvekugadzira.Ndarama nesirivha zvinoshandiswa ne electroplating, nepo vatengesi vasina mutobvu uye vane mutobvu vanoiswa zvakachinjika nemhepo inopisa solder.
11. Nomenclature
Mazhinji maPCB akadzivirirwa pamicherechedzo iri pamusoro pavo.Aya mamark anonyanya kushandiswa mukuita gungano uye anosanganisira mienzaniso yakaita sereferensi mamaki uye polarity mamaki.Zvimwe zvinomaka zvinogona kuve nyore sechikamu chekuzivikanwa kwenhamba kana macode emazuva ekugadzira.
12. Sub-bhodhi
MaPCB anogadzirwa mune akazara ekugadzira mapaneru anoda kubviswa kubva mukugadzira kwavo contours.Mazhinji maPCB akaiswa mumitsetse yekuvandudza kushanda kwegungano.Panogona kuve nenhamba isingaperi yearrays aya.Haikwanise kutsanangura.
Mazhinji arrays angave akagaiwa pachigayo cheCNC achishandisa maturusi ecarbide kana kuhwina uchishandisa maturusi akavharwa nedhaimani.Nzira dzose dziri mbiri dzinoshanda, uye sarudzo yenzira inowanzosarudzwa neboka regungano, iro rinowanzobvumira hurongwa hwakavakwa pakutanga.
13. Muedzo
Vagadziri vePCB vanowanzo shandisa probe inobhururuka kana mubhedha wekuyedza zvipikiri.Nzira yekuyedza inotarwa nehuwandu hwechigadzirwa uye/kana midziyo iripo
