Maburi panePCBinogona kuiswa mumabhawa kuburikidza nemakomba (pth) uye isina-yakaiswa kuburikidza nemakomba (NPTH) zvichienderana nekubatana kwemagetsi.
Yakarongedzwa kuburikidza negomba (pth) zvinoreva gomba nesimbi inofamba pamadziro ayo, iyo inogona kuzadzisa kubatana kwemagetsi pakati pematanho emukati, kunze kweiyo PCB. Saizi yayo inotemwa nehukuru hwegomba rakakwenenzverwa uye ubvu hwenzvimbo yakarongedzwa.
Isiri-yakarongedzwa kuburikidza nemakomba (NPTH) maburi asina kutora chikamu mukubatana kwemagetsi kwePCB, anozivikanwawo seasina-simbi maburi. Maererano nedanda iro gomba rinopinda mukati mePCB, maburi anogona kutaurwa se-gomba, akavigwa kuburikidza / gomba, uye bole.
Kupfuura-maburi anopinda pani yese uye inogona kushandiswa kune zvemukati kubatana uye / kana kumisikidza uye kukwira zvinhu. Pakati pavo, maburi anoshandiswa pakugadzirisa uye / kana magetsi ekubatanidza aine zvikamu zvidimbu (kusanganisira mapini uye waya) paPCB inodaidzwa kuti zvikamu. Yakarongedzwa kuburikidza-maburi anoshandiswa kune emukati miviri yekubatanidza asi pasina kukwira chikamu chinotungamira kana zvimwe zvinosimbisa zvinhu zvinonzi nemakomba. Kune kunyanya zvinangwa zviviri zvekukwevera kuburikidza ne-maburi pane bhodhi, kubvumira nzira inotevera kuumba magetsi pakati peiyo yepamusoro, uye nzvimbo yemukati yebhodhi; Imwe yacho ndeyekuchengetedza kutendeka kwekuvimbika uye kumisa chokwadi checomputer yekuisa pabhodhi.
Mapofu Mapofu uye akavigwa Vias anoshandiswa zvakanyanya mulents-desity (HDI) tekinoroji yeHDI PCB, kazhinji mune yakakwira matafura PCB mabhodhi. Bofu Viall kazhinji inobatanidza yekutanga dura kune yechipiri layer. Mune mamwe magadzirirwo, mapofu vias anogona zvakare kubatanidza denderedzwa rekutanga kujere. Nekubatanidza mapofu uye akaviga vias, kubatana kwedunhu rakakwira uye rakakwirira rekirabhu rekushongedza rinodiwa HDI rinogona kuwanikwa. Izvi zvinobvumidza kuwedzera dengs deyer mune madiki midziyo kana uchivandudza kutapurirana kwemagetsi. Yakavanzika vias inobatsira kuchengetedza dunhu redunhu lightweight uye compact. Mapofu uye akavigwa kuburikidza nehurongwa hunowanzoshandiswa mune yakaoma-dhizaini, kuremerwa-kuremerwa, uye yakakwirira-inodhura zvemagetsi zvigadzirwa zvemagetsi zvakadaismartphones, mahwendefa, uyeZvekushandisa Zvekushandisa.
Bofu Viasinoumbwa nekudzora kudzika kwekukwezva kana laser kubviswa. Iyo yekupedzisira iripo nzira yakajairika. Kugadziriswa kwe kuburikidza nemakomba anoumbwa kuburikidza nekutsvagira. Izvo zvinokonzerwa nemakomba anokwanisa kuiswa kana kudzikiswa, kuwedzera mamwe ekugadzira uye ekuongorora matanho uye anowedzera mutengo.
Zvinoenderana nechinangwa uye basa remakomba, ivo vanogona kuve vanokatyiswa se:
Kuburikidza nemakomba:
Iwo masimbi makomba anoshandiswa kuzadzisa kubatana kwemagetsi pakati pezvakasiyana zviyero pane PCB, asi kwete nekuda kwechinangwa chekukwirisa.
PS: Via mabhebhi anogona kuwedzeredzwa mukati me-gomba, akaviga gomba, uye hole bofu, zvichienderana nedumbu rakapinda mukati mePCB sezvataurwa pamusoro apa.
Component Holes:
Ivo vanoshandiswa kutengesa uye kugadzirira plug-muzvikamu zvemagetsi, pamwe neye-maburi anoshandiswa pakubatana kwemagetsi pakati pezvakasiyana zviyero. Component maburi anowanzo kuve simbi, uye anogona zvakare kushanda seinzvimbo dzekuwana dzekubatanidza.
Kukwirisa Makomba:
Iwo maburi akakura ari paPCB anoshandiswa kuchengetedza PCB kune iyo casing kana imwe yekutsigira chimiro.
Slot maburi:
Ivo vanoumbwa pamwe nekubatanidza otomatiki akawanda maburi kana kubaya grooves muchirongwa chekurovedza chemuchina. Ivo vanowanzoshandiswa sekukwira mapoinzi emapipi ekubatanidza, senge madiki-akaumbwa-akaumbwa pini yechibvumirano.
Backdrill maburi:
Ivo vane makomba akadzika akadzika vakadamwa mumabhawa akapetwa pane PCB kuti iparadzanise stub uye kuderedza chiratidzo chekutapurirana panguva yekutapurirana.
Kutevera ndedzimwe maburi ebetsero iyo PCB Vagadziri vanogona kushandisa muPCB Kugadzira Processkuti PCB Dhizaina mainjiniya anofanirwa kujaira:
● Kuwana maburi matatu kana mana maburi kumusoro uye pasi pePCB. Mamwe maburi ari pabhodhi akabatanidzwa nemakomba aya seyenongedzo nzvimbo yekuisa mapini uye kugadzirisa. Zvakare zvinozivikanwa seanenge target maburi kana chinzvimbo chinzvimbo hove, ivo vanogadzirwa neyekuchina hole muchina
●Romukati layer alignmentMakomba mamwe maburi ari pamucheto weiyo multlayer bhodhi, yaishandiswa kuona kana paine kutsauka mune iyo multilayer bhodhi usati wairaira mukati mebhodhi. Izvi zvinosarudza kana chirongwa chekurovedza chinoda kugadziriswa.
● Makomba emitsara itsetse madiki madiki matombo kune rimwe divi rebhodhi rinoshandiswa kuratidza rumwe ruzivo, semuchina wechigadzirwa, etces codes, mafekitori mazhinji anoshandisa laser chiratidzo pachinzvimbo.
● Makomba emakwenzi mamwe maburi ehukuru hwakasiyana pamucheto webhodhi, aimbozivisa kana dhizaini yekudhara iri chaiyo panguva yekukwevera. Mazuva ano, mafekitori mazhinji anoshandisa mamwe matekinoroji nechinangwa ichi.
● BreakAy tabs ari kuisa maburi anoshandiswa kune PCB yekunyora uye kuongororwa kuti aratidze mhando yemakomba.
● Yakarongedzwa maburi emabhawa akavezwa maburi anoshandiswa pakuedza kutadza kwePCB.
● Mahwanda anofungidzira anowanzove maburi asina-akasarudzika anoshandiswa kudzivirira bhodhi riri kuiswa kumashure, uye kazhinji anoshandiswa mukumisa panguva yekuumbwa kana kufungidzira maitiro.
● Kusimudza maburi kazhinji makomba asina-akasarudzika anoshandiswa kune zvinoenderana nemaitiro.
● Rivet maburi asina-akaiswa maburi anoshandiswa pakugadzirisa riviti pakati pega yega yega yeCore zvinhu uye sheething sheet panguva yekuchinjika kwemugwagwa. Chinzvimbo cheRivet chinoda kubhururuka kuburikidza nekukwevera kwekudzivirira kuti udzivise mabhuruku kubva panzvimbo iyoyo, iyo inogona kukonzera kuputsa kwebhodhi mumabhodhi gare gare maitiro.
