PCB bare board ngezigaba

Ngokuya ngenani lezendlalelo, ibhodi lesifunda lihlukaniswe nge-single single PCB, Double Layer PCB, kanye ne-multi-layer circuit board imikhakha emithathu emikhulu.

Owokuqala uyibhodi lesifunda elinohlangothi olulodwa. Ku-PCB eyisisekelo kunazo zonke, izingxenye zigxilwe ohlangothini olulodwa nezintambo ngakolunye uhlangothi.Lolu hlobo lwe-PCB lubizwa ngokuthi ibhodi lesifunda elinohlangothi olulodwa ngoba izintambo zivela kuphela ohlangothini olulodwa.Amapaneli angashadile ngokuvamile alula ukwenza futhi aphansi ngezindleko, kepha okubi ukuthi azikwazi ukusetshenziswa kumikhiqizo eyinkimbinkimbi kakhulu.

Amabhodi wesifunda anezinhlangothi ezimbili ukwelulwa kwebhodi lesifunda elenhlangothi elilodwa. Lapho i-wiring single-layer ingakwazi ukuhlangabezana nezidingo zemikhiqizo ye-elekthronikhi, kusetshenziswa iphaneli ephindwe kabili.Zombili izinhlangothi zinezembatho zethusi kanye nezintambo, futhi izintambo eziphakathi kwalezi zingqimba ezimbili zingaqondiswa emgodini ukwakha ukuxhumana okudingekayo kwenethiwekhi.

Ibhodi lesifunda le-Multilayer libhekisa ebhodini eliphrintiwe eliqukethe izingqimba ezintathu noma ngaphezulu zemidwebo ehlukanisiwe nezinto zokwakha ezikuyo, futhi ihluzo elenzayo lixhumene njengoba kudingeka.Imultilayer board board ingumkhiqizo wobuchwepheshe bolwazi ngogesi oqonde ngejubane elikhulu, imisebenzi eminingi, umthamo omkhulu, ivolumu encane, mncane futhi ayisindi.

Ngokuya ngezimpawu zebhodi lesifunda lihlukaniswe laba yibhodi elithambile (i- FPC ), ibhodi eliqinile (i- PCB ), ibhodi elihlangene nelithambile ).

Ungahlukanisa kanjani ibhodi lesifunda elinamasendlalelo amaningi ebhodini lesifunda elinelayini elilodwa

1. Yiphakamisele phezulu ekukhanyeni. Ingqikithi yangaphakathi ilula-okuqinile, okungukuthi, konke kumnyama, okungukuthi, ibhodi le-multilayer; ngakolunye uhlangothi, iphaneli elilodwa nelimbili, kuyilapho iphaneli elilodwa line ungqimba olulodwa kuphela lwesekethe futhi alukho ithusi emgodini.Iphaneli eliphindwe kabili lingolayini bangaphambili nabasemuva, hola umgodi ngethusi.

2. Umehluko obaluleke kunazo zonke inani lemigqa:

Isendlalelo esisodwa sebhodi lesifunda line ungqimba olulodwa lwesifunda (ungqimba lwethusi), zonke izimbobo ziyizimbobo ezingezona ezensimbi, akukho nqubo yokuqothula

Ibhodi lesifunda elinosendlalelo kabili linezingqimba ezimbili zesekethe (ungqimba lwethusi), imbobo yensimbi kanye nomgodi ongagudluki, inqubo yokwenza ugesi

3. Ibhodi lesifunda lihlukaniswe laba yibhodi lesifunda elinohlangothi olulodwa, ibhodi lesifunda elinamacala amabili kanye nebhodi lesifunda elinamatshe amaningi. Ibhodi lesifunda elinamasendlalelo amaningi libhekisele ebhodini lesifunda elinezendlalelo ezintathu noma ngaphezulu.Inqubo yokukhiqiza yebhodi yesekethe enezingqimba eziningi izosuselwa kuphaneli elilodwa neliphindwe kabili kanye nenqubo yokukhiqizwa kokucindezela ungqimba lwangaphakathi.Ukusebenzisa isiphazamiso sokusikwa nakho kungahlaziywa.

Yimiphi imikhiqizo edinga ibhodi le-PCB

Imikhiqizo ye-elekthronikhi edinga amasekethe ahlanganisiwe kufanele iguqulwe ibe amabhodi wesekethe aphrintiwe ukuze konge isikhala, yenze imikhiqizo ibe lula / iqine kakhudlwana / futhi ifinyelele ekusebenzeni okuhle.I-PCB ihlangabezana nezidingo zesikhala / ukusebenza kanye nokwethembeka kahle.

Akuzona zonke izinto zikagesi ezidinga ibhodi lesifunda, izinto zikagesi ezilula ezingazenza ngaphandle kwesekethe njengemoto kagesi Kodwa izinto ezinemisebenzi ethile zidinga ukuthi amabhodi wesifunda asetshenziswe njengamathelevishini, imisakazo, amakhompyutha, nokunye okuningi. Isipheki selayisi sine-PCB ezansi, umbusi kufeni,

Hlobo luni imikhiqizo sebenzisa PCB ibhodi

Ibhodi lesifunda elinzima i-PCB ngokuvamile ibhekisele, kubhodi yomama efana nekhompyutha, igundane, imidwebo, imishini yehhovisi, amaphrinta, amakhophi, isilawuli kude, zonke izinhlobo zamashaja, umshini wokubala, ikhamera yedijithali, umsakazo, i-motherboard ye-TV, ikhebuli yesikhulisi, iselula, ukuwasha umshini, isikali se-elekthronikhi, ifoni, amalambu e-LED namalambu, izinto zasendlini ezisebenza ngogesi: ama-air conditioners, amafriji, umsindo, i-MP3, imishini yezimboni, i-GPS, imoto, izinsimbi zomculo, izinsimbi zokwelapha, izindiza, izikhali zamasosha, imicibisholo, iziphuphutheki, njll. I-APCB nayo iyibhodi yesifunda, kepha ithambile, njengesembozo sokuxhuma ifoni se-clamshell futhi ukhiye ophakathi kwesifunda uyasetshenziswa ebhodini lesifunda).

Ibhodi lomama lomakhalekhukhwini, cindezela ibhodi lokhiye, ibhodi elinzima; Amafoni okushelela noma ama-clamshell axhunywe kulayini yipuleti elithambile.Isilawuli kude ngokuvamile SISEBENZISA ipuleti lefilimu lekhabhoni.Ibhodi lezingcingo ezisuka phezulu liye ngokulandelana i-rf isekethe, isekethe yamandla, isekhethi elilalelwayo, isifunda esinengqondo

Ngokuvamile nje ukufudumeza iketela akukho ibhodi lesifunda, ubakaki wocingo uxhunywe ngqo.Ama-dispensers wamanzi anamabhodi wesifunda.Abapheki belayisi bavame ukuba namabhodi wesifunda.I-cooker yokungeniswa inebhodi lesifunda.Kunebhodi lesifunda ku-fan kagesi, kepha ngokuvamile idlala umsebenzi wokulawulwa kwejubane, isikhathi, isibonisi njalonjalo, futhi ukusebenza kwesiphepheli sikagesi akunamphumela osebenzayo.

Yimiphi imikhiqizo esebenzisa izingqimba eziphindwe kabili nokuthi yimiphi imikhiqizo esebenzisa izendlalelo eziningi

Ngokuyinhloko kuncike ekutheni izidingo zokusebenza zedesika ephindwe kabili zingahlangatshezwa yini, njengekhono lokulwa nokuphazanyiswa, izintambo, izidingo ze-EMC nokunye ukusebenza kwedeski eliphindwe kabili kungafezekiswa, asikho isidingo sokusebenzisa ibhodi enezingqimba eziningi.

Yikuphi okungcono, ibhodi lesifunda elinama-multilayer noma ibhodi elilodwa lesifunda

I-Multilayer board iyinhlangano yebhodi lesifunda esetshenziswa kakhulu empilweni yansuku zonke.Yiziphi izinzuzo zesicelo sebhodi yesifunda se-PCB esinezendlalelo eziningi?

Izinzuzo Isicelo multi-ungqimba PCB ibhodi:

1.Umhlangano ophakeme kakhulu, ivolumu encane nesisindo esincane ziyahlangabezana nezidingo zokukhanya nokusebenzisa kancane imishini kagesi;

2. Ngenxa yobuningi bomhlangano omkhulu, ukuxhumana phakathi kwengxenye ngayinye (kufaka phakathi izinto) kuncishisiwe, ngokufakwa okulula nokuthembeka okuphezulu;

3. Ngenxa yokuphindaphindwa nokufana kwemidwebo, amaphutha okuhlanganisa izintambo nawomhlangano ancishisiwe futhi isikhathi sokugcinwa, ukulungisa amaphutha nokuhlolwa kwemishini siyagcinwa;

4. Lingenyuka inani lezendlalelo zezintambo, ngaleyo ndlela kwandiswe ukuguquguquka kokuklama;

I-5, ingakha isifunda esithile se-impedance, ingakha isifunda sokudlulisa esinejubane elikhulu;

6. Isendlalelo sokuvikela isekethe nesibuthe singasethwa, futhi ungqimba wensimbi wokushisa ukushisa ongasetshenziswa nawo ungasethwa ukuhlangabezana nezidingo zemisebenzi ekhethekile njengokuvikela nokuchitha ukushisa.

Ngokuthuthuka okuqhubekayo kobuchwepheshe be-elekthronikhi kanye nekhompyutha, ezokwelapha, ezokundiza nezinye izimboni ekuthuthukisweni okuqhubekayo kwezidingo zemishini ye-elekthronikhi, amabhodi wesifunda ancipha ngevolumu, anciphisa ikhwalithi futhi anda ngobuningi.Ngenxa yomkhawulo wendawo etholakalayo, akunakwenzeka ukuqhubeka nokuthuthukisa ukuminyana kwenhlangano yamabhodi aphrintiwe angamacala amabili nelilodwa. Ngakho-ke, kuyadingeka ukuthi ucabangele ukusebenzisa amabhodi wesekethe anezendlalelo eziningi ngezendlalelo eziningi nobukhulu bezinhlangano eziphakeme.Ibhodi lesifunda lesendlalelo esinemiklamo eguquguqukayo, ukusebenza ngogesi okuzinzile nokunokwethenjelwa nokusebenza kwezomnotho okuphakeme, kusetshenziswe kabanzi ekukhiqizeni i-elekthronikhi imikhiqizo.
