Isicelo

Ibhodi le-PCB elinembobo ewuhhafu lisho inqubo yesibili yokubhoboza nokuma ngemva kokuba imbobo yokuqala ibhoboziwe, futhi ekugcineni ingxenye yomgodi oyinsimbi igodliwe.Inhloso ukushisela ngokuqondile unqenqema lwembobo onqenqemeni oluyinhloko ukuze konge izixhumi nesikhala, futhi kuvame ukuvela kumasekhethi esignali.
Amabhodi esekethe anembobo enguhhafu ajwayele ukusetshenziselwa ukukhweza izingxenye ze-elekthronikhi ezinobukhulu obuphezulu, njengamadivayisi eselula, amawashi ahlakaniphile, okokwelashwa, okokusebenza okulalelwayo nevidiyo, njll. Anika amandla ukuminyana kwesekethe okuphakeme kanye nezinketho eziningi zokuxhumana, okwenza izinto zikagesi zibe zincane, zibe lula. futhi esebenza kahle kakhulu.

Imbobo enguhhafu engagqitshiwe emaphethelweni e-PCB ingenye yezinto ezivame ukusetshenziswa eziklanyweni zenqubo yokukhiqiza ye-PCB, futhi umsebenzi wayo oyinhloko ukulungisa i-PCB.Enqubweni yokukhiqiza ibhodi le-PCB, ngokushiya izimbobo eziyingxenye ezindaweni ezithile onqenqemeni lwebhodi le-PCB, ibhodi le-PCB lingalungiswa kudivayisi noma endlini ngezikulufo.Ngesikhathi esifanayo, phakathi nenqubo yokuhlanganisa ibhodi le-PCB, imbobo enguhhafu isiza futhi ukubeka nokuqondisa ibhodi le-PCB ukuze kuqinisekiswe ukunemba nokuzinza komkhiqizo wokugcina.

Imbobo yesigamu efakwe eceleni kwebhodi lesifunda ukuthuthukisa ukuthembeka kokuxhumeka kohlangothi lwebhodi.Ngokuvamile, ngemva kokusikwa kwebhodi lesifunda eliphrintiwe (PCB), ungqimba lwethusi oluveziwe onqenqemeni luzovezwa, oluthambekele ekubeni ne-oxidation kanye nokugqwala.Ukuze uxazulule le nkinga, ungqimba lwethusi luvame ukumbozwa ungqimba oluvikelayo ngokufaka i-electroplating onqenqemeni lwebhodi lube yimbobo eyisigamu ukuze kuthuthukiswe ukumelana ne-oxidation nokumelana nokugqwala, futhi kungandisa indawo yokushisela futhi kuthuthukise ukwethembeka ukuxhumana.

Enkambweni yokucubungula, indlela yokulawula ikhwalithi yomkhiqizo ngemva kokwenza izimbobo ze-semi-metallized emaphethelweni ebhodi, njengameva ethusi odongeni lwembobo, njll., bekulokhu kuyinkinga enzima ohlelweni lokucubungula.Kulolu hlobo lwebhodi olunomugqa wonke wezimbobo ze-semi-metallized Ibhodi le-PCB libonakala ngobubanzi bembobo encane, futhi lisetshenziselwa kakhulu ibhodi lendodakazi yebhodi lomama.Ngalezi zimbobo, ihlanganiswe nebhodi lomama kanye nezikhonkwane zezingxenye.Lapho i-soldering, izoholela ekuhlanganisweni okubuthakathaka, i-solder yamanga, kanye nokujikeleza okufushane kwebhuloho phakathi kwamaphini amabili.

Imibuzo Evame Ukubuzwa

1.Iyini inhloso yembobo epuletiwe?

Kungase kube usizo ukubeka izimbobo ezinamapulangwe (PTH) onqenqemeni lwebhodi.Isibonelo uma ufuna ukudayisela ama-PCB amabili komunye nomunye nge-engeli engu-90° noma lapho unamathisela i-PCB ku-casing yensimbi.

2.Yimiphi imikhiqizo evame ukusetshenziselwa yona?

Isibonelo, inhlanganisela yamamojula ayinkimbinkimbi e-microcontroler anama-PCB ajwayelekile, aklanywe ngawodwana.Ezinye izinhlelo zokusebenza ziyizibonisi, i-HF noma amamojula e-ceramic adayiswa ebhodini lesifunda eliphrintiwe.

3.PCB inqubo yokukhiqiza for plated uhhafu imbobo

Ukubhoboza- okugqitshwe ngembobo (PTH) - ukufakwa kwephaneli - ukudluliswa kwesithombe - i-pattern plating -pth isigamu sembobo- striping - etching - solder mask - isikrini sikasilika - ukwelashwa kwendawo.

4.Yimuphi usayizi we-PTH uhhafu wembobo odingekayo?

1.Ububanzi ≥0.6MM;

2.Ibanga phakathi komkhawulo wembobo ≥0.6MM;

3. Ububanzi bendandatho yokufaka idinga u-0.25mm;

5.Kungani idinga ukukhokhiswa okwengeziwe nge-pth half-hole PCB?

I-Half-hole iyinqubo ekhethekile.Ukuze kuqinisekiswe ukuthi kunethusi emgodini, kufanele kugaywe kuqala ngaphambi kokucwenga inqubo yethusi.I-PCB yembobo ewuhhafu ejwayelekile incane kakhulu, ngakho-ke izindleko zayo zibiza kakhulu kune-PCB evamile.
