Imibuzo Evame Ukubuzwa

Q: Kuyini 2 layer PCB?

I-PCB enezingqimba ezi-2 iyithusi embozwe nhlangothi zombili ngongqimba oluvikelayo phakathi nendawo.Inezingxenye ezinhlangothini zombili zebhodi, yingakho ibizwa nangokuthi i-PCB enezinhlangothi ezimbili.Akhiwa ngokuhlanganisa izendlalelo ezimbili zethusi ndawonye, ​​kube nento edielectric phakathi.

Q: 2 izendlalelo PCB vs. 4 izingqimba PCB: yini umehluko?

Ungakwazi ukuphetha ngokuthi uyini umehluko obonakalayo phakathi kwezingqimba ezi-2 ze-PCB nezingqimba ezi-4 ze-PCB ngokwamagama azo.2 izendlalelo PCB has imikhondo ezimbili emaceleni nge ungqimba phezulu naphansi, kuyilapho 4 izingqimba PCB has 4 izendlalelo.Uma uqonda kangcono izinhlobo ezimbili zamabhodi e-PCB, uzothola ukuthi kunomehluko omningi endleleni akhiwe ngayo kanye nendlela yokusebenza.

Q: Ama-PCB Asohlangothini Olulodwa Namaceleni Amabili - Uyini Umehluko?

Ukulandelelwa kwe-PCB yohlangothi olulodwa kukhona ohlangothini olulodwa kuphela, kuyilapho ama-PCB anezinhlangothi ezimbili anemikhondo nhlangothi zombili enezendlalelo ezingaphezulu neziphansi.Izingxenye nethusi eliqhutshwayo kugitshezwe nhlangothi zombili ze-PCB enamacala amabili, futhi lokhu kuholela ekuhlanganeni noma ukugqagqana komkhondo.

Q: Ngingathola i-oda le-prototype lamahhala lebhodi lezingqimba ezi-2?

Yebo, vele usithumelele ifayela lakho le-gerber.

Q: Yisiphi isikhathi sokuhola esijwayelekile se-oda lesibonelo?

3WDS.

I2 ungqimba PCB(i-PCB enezinhlangothi ezimbili) iyibhodi lesifunda eliphrintiwe elinethusi elimbozwe nhlangothi zombili, phezulu nangaphansi.Kukhona i-insulating layer phakathi, okuyibhodi lesifunda eliphrintiwe elivame ukusetshenziswa.Zombili izinhlangothi zingahlelwa futhi zithengiswe, okunciphisa kakhulu ubunzima bokuhlelwa, ngakho-ke isetshenziswa kabanzi.

Ukuze usebenzise ama-circuits ezinhlangothini zombili, kufanele kube nokuxhumana kwesifunda okufanele phakathi kwezinhlangothi ezimbili."Amabhuloho" phakathi kwamasekhethi anjalo abizwa ngokuthi i-vias.I-Via iyimbobo encane ebhodini le-PCB egcwele noma embozwe ngensimbi, engaxhunywa namasekhethi nhlangothi zombili.Ngenxa yokuthi indawo yebhodi enezinhlangothi ezimbili iphindwe kabili kunebhodi elilodwa elihlangene, ibhodi elinezinhlangothi ezimbili lixazulula ubunzima bebhodi elilodwa ngenxa yesakhiwo esihlanganisiwe (ingaxhunywa ngakolunye uhlangothi. ngokusebenzisa izimbobo), futhi ifaneleka kakhulu kumasekethe ayinkimbinkimbi kunebhodi elinohlangothi olulodwa.

Sidinga imikhiqizo ye-elekthronikhi esebenza kahle kakhulu, usayizi omncane, kanye nemisebenzi eminingi, ekhuthaza ukuthuthukiswa kokukhiqizwa kwebhodi lesifunda eliphrintiwe ukuze kube lula, kube mncane, kufushane, futhi kuncane.Ngesikhala esilinganiselwe, imisebenzi eminingi ingenziwa, ukuminyana kwesakhiwo kuye kwaba kukhulu, futhi ububanzi bembobo buncane.Ububanzi bembobo obuncane bomthamo wokumba owenziwe ngomshini wehlile ukusuka ku-0.4mm kuya ku-0.2mm noma ngisho nangaphansi kwalokho.Ububanzi bembobo ye-PTH buba buncane futhi buncipha.Izinga le-PTH (I-Plated Through Hole) lapho ukuxhumeka kwesendlalelo kuya kwesendlalelo kuncike ngokuqondile kuhlobene nokuthembeka kwebhodi lesifunda eliphrintiwe.
