Kungabhekwa ukuthi kunezimbobo eziningi ezinkulu nezincane ebhodini lesifunda, futhi kungatholakala ukuthi kunezimbobo eziningi eziminyene, futhi imbobo ngayinye yenzelwe injongo yayo. Lezi zimbobo zingahlukaniswa zibe i-PTH (Plating Through Hole) kanye ne-NPTH (Non Plating Through Hole) imboza ngembobo, futhi sithi "ngomgodi" ngoba isuka ngokoqobo isuka kolunye uhlangothi lwebhodi iye kolunye, Eqinisweni, ngaphezu kwembobo edlula ebhodini lesifunda, kunezinye izimbobo ezingekho ebhodini lesifunda.
Imigomo ye-PCB: ngembobo, imbobo eyimpumputhe, imbobo egqitshiwe.
1. Indlela yokuhlukanisa i-PTH ne-NPTH ngemigodi?
Kungahlulelwa uma kukhona izimpawu ezikhanyayo ze-electroplating odongeni lwembobo. Imbobo enamamaki e-electroplating yi-PTH, futhi imbobo engenawo amamaki e-electroplating yi-NPTH. Njengoba kukhonjisiwe esithombeni esingezansi:
2. IUInani eliphakeme kakhulu lama-NPTH
Kutholwe ukuthi indawo yokuvula ye-NPTH ivamise ukuba nkulu kune-PTH, ngoba i-NPTH isetshenziswa kakhulu njengesikulufu sokukhiya, futhi okunye kusetshenziselwa ukufaka okunye ukuxhumana ngaphandle kwesixhumi esilungisiwe. Ngaphezu kwalokho, ezinye zizosetshenziswa njengendawo yokuhlola eceleni kwepuleti.
3. Ukusetshenziswa kwe-PTH, Iyini i-Via?
Ngokuvamile, izimbobo ze-PTH ebhodini lesifunda zisetshenziswa ngezindlela ezimbili. Enye isetshenziselwa ukushisela izinyawo zezingxenye ze-DIP zendabuko. Ukuvuleka kwalezi zimbobo kufanele kube kukhulu kunobubanzi bezinyawo zokushisela zezingxenye, ukuze izingxenye zifakwe emigodini.
Enye i-PTH encane, evame ukubizwa ngokuthi nge (imbobo yokuqhuba), isetshenziselwa ukuxhuma nokuqhuba ibhodi lesifunda (PCB) phakathi kwezingqimba ezimbili noma ngaphezulu zomugqa wethusi we-foil, ngoba i-PCB yakhiwe ngezingqimba eziningi zethusi ezihlanganiswe, ungqimba lwethusi ngalunye (ithusi) luzogandaywa ngongqimba lwe-insulation layer, okusho ukuthi, ungqimba lwethusi alukwazi ukuxhumana ngokusebenzisa isignali yayo, " IsiShayina. Via ngoba izimbobo azibonakali ngokuphelele ngaphandle. Ngoba inhloso ye-via ukwenza i-foil yethusi yezendlalelo ezihlukene, idinga i-electroplating ukuze iqhube, ngakho-ke i-via nayo iwuhlobo lwe-PTH.
