Chii chinonzi heavy copper PCB?

Iyi PCB classic ndiyo yekutanga sarudzo kana mafungu akakwira asingadzivisike: iyo gobvu yemhangura PCB , yakagadzirwa mune chaiyo etching tekinoroji. Makobvu maPCB emhangura anoratidzwa nezvimiro zvine hukobvu hwemhangura kubva pa105 kusvika 400 µm. Aya maPCB anoshandiswa kune hombe (yepamusoro) zvinobuda uye nekugadzirisa kweiyo thermal manejimendi. Iyo gobvu mhangura inobvumira yakakura PCB-muchinjika-zvikamu zvemitoro yakakwira ikozvino uye inokurudzira kupisa kupisa. Magadzirirwo anonyanyozivikanwa ndeakawanda kana maviri-mativi. 

Kunyange zvazvo pasina tsananguro yakajairika yeHeavy Copper, inogamuchirwa kuti kana 3 ounces (oz) yemhangura kana kupfuura yakashandiswa mukati uye kunze kwezvikamu zvebhodhi redunhu rakadhindwa, inonzi PCB inorema yemhangura . Chero dunhu rine hukobvu hwemhangura hunopfuura 4 oz paskweya tsoka (ft2) inoiswawo muchikamu sePCB inorema yemhangura. Mhangura yakanyanyisa zvinoreva 20 oz paft2 kusvika 200 oz paft2.

PCB yemhangura inorema inozivikanwa sePCB ine hukobvu hwemhangura 3 oz pa ft2 kusvika 10 oz pa ft2 muzvikamu zvekunze nemukati. PCB yemhangura inorema inogadzirwa nehuremu hwemhangura kubva pa4 oz paft2 kusvika pa20 oz paft2. Iyo yakagadziridzwa huremu hwemhangura, pamwe chete neyakakora plating uye yakakodzera substrate mumaburi-maburi inogona kushandura bhodhi isina simba kuita inogara kwenguva refu uye yakavimbika wiring chikuva. Heavy copper conductors inogona kuwedzera iyo yose PCB ukobvu zvakanyanya. Ukobvu hwemhangura hunofanira kugara uchitariswa panguva yedunhu rekugadzira danho. Ikozvino-inotakura simba inotarirwa kubva pahupamhi uye kukora kwemhangura inorema.

Chakanyanya bhenefiti yemabhodhi edunhu rinorema mhangura kugona kwavo kurarama vachigara vachisangana neakanyanya ikozvino, tembiricha yakakwira uye kudzokororwa kuchovha bhasikoro, izvo zvinogona kuparadza bhodhi redunhu mumasekondi. Iyo inorema mhangura bhodhi ine yakakwirira kushivirira kugona, iyo inoita kuti ienderane nekushandisa mumamiriro ezvinhu akaoma senge, kudzivirira uye aerospace indasitiri zvigadzirwa.

Mamwe emamwe mabhenefiti eanorema emhangura edunhu mabhodhi ndeaya:

Compact chigadzirwa saizi nekuda kwehuremu hwemhangura akati wandei pane imwechete layer yedunhu

Heavy copper-plated vias inopfuudza yakakwira yazvino kuburikidza nePCB uye inobatsira kuendesa kupisa kune yekunze kupisa singi.

Musiyano pakati peiyo Yakajairwa PCB uye Gobvu Copper PCB

Standard PCBs inogona kugadzirwa nemhangura etching uye plating maitiro. Aya maPCB akaputirwa kuti awedzere ukobvu hwemhangura kundege, mitsvairo, PTHs, uye mapadhi. Huwandu hwemhangura hunoshandiswa mukugadzira maPCB akajairwa i1oz. Mukugadzirwa kwePCB yemhangura inorema, huwandu hwemhangura hunoshandiswa hwakakura kupfuura 3oz.

Kune akajairwa edunhu mabhodhi, mhangura etching uye plating matekiniki anoshandiswa. Nekudaro, inorema yemhangura PCB inogadzirwa kuburikidza nekusiyanisa etching uye nhanho platting. MaPCB akajairwa anoita mabasa akareruka nepo mabhodhi emhangura anorema achiita mabasa anorema.

Standard PCBs inoitisa yakaderera ikozvino nepo inorema mhangura PCBs inoitisa yakakwira ikozvino. Makobvu emhangura maPCB akanakira kushandiswa kwepamusoro-soro nekuda kwekugovera kwavo kupisa kwakanaka. Heavy mhangura PCBs ane zviri nani mechanical simba pane standard PCBs. Heavy copper circuit boards inowedzera kugona kwebhodhi maanoshandiswa.

Zvimwe zvinhu zvinogadzira maPCB akakora emhangura akasiyana nemamwe maPCB

Huremu hwemhangura: Ichi ndicho chinonyanya kusiyanisa chimiro chePCB inorema yemhangura. Huremu hwemhangura zvinoreva huremu hwemhangura hunoshandiswa munzvimbo ine sikweya tsoka. Huremu uhwu hunowanzoyerwa nemaonzi. Inoratidza ukobvu hwemhangura padandemutande.

Outer layers: Aya anoreva zvidimbu zvendarira zvekunze zvebhodhi. Zvigadzirwa zvemagetsi zvinowanzobatanidzwa kune zvikamu zvekunze. Matunhu ekunze anotanga nefoiri yemhangura iyo yakashongedzwa nemhangura. Izvi zvinobatsira kuwedzera ukobvu. Huremu hwemhangura hwematanho ekunze hwakagadzirirwa dhizaini yakajairwa. Heavy copper PCB mugadziri anogona kushandura huremu uye ukobvu hwemhangura kuti ienderane nezvaunoda.

Inner layers: Ukobvu hwedielectric, pamwe nehuremu hwemhangura hwezvikamu zvemukati, zvakafanotsanangurwa kumapurojekiti akajairwa. Nekudaro, huremu hwemhangura uye ukobvu muzvikamu izvi zvinogona kugadziridzwa zvichienderana nezvaunoda.

Heavy copper PCBs anoshandiswa kune zvinangwa zvakawanda zvakadai mumapurani emagetsi, kupisa kupisa, kugovera simba guru, magetsi ekushandura, nezvimwewo. Pane kuwedzera kudiwa kwemapuranga anorema emhangura mumakombiyuta, motokari, mauto, uye maindasitiri ekutonga.

Heavy copper yakadhindwa edunhu mabhodhi anoshandiswawo mu:

Zvigadzirwa zvemagetsi, magetsi anoshandura

Kugovera simba
