Kungaphangwa ukuthi kunezimbobo eziningi ezinkulu nezincane ebhodini lesekethe, futhi kungatholakala ukuthi kunezimbobo eziningi eziminyene, futhi umgodi ngamunye wenzelwe inhloso yawo. Lezi zimbobo zingahlukaniswa ngehlukaniswe nge-pth (ifaka amapuleti nge-hole) ne-npth (i-npth (i-annow pay hole) ipuleti ngokusebenzisa umgodi, empeleni, isuka kolunye uhlangothi lweBhodi liye kwelinye, kunezinye izimbobo ezingezona ngeBhodi Yesekethe.

Imibandela ye-PCB: Ngokusebenzisa umgodi, imbobo eyimpumputhe, umgodi ongcwatshwe.

1. Ungayihlukanisa kanjani i-Pth ne-NPTH ngokusebenzisa izimbobo?

Ingahlulelwa uma kukhona amamaki akhanyayo we-electroplating odongeni lomgodi. Umgodi onamamaki we-electroplating yi-pth, futhi umgodi ngaphandle kwamamaki we-electroplating yi-npth. Njengoba kukhonjisiwe esithombeni esingezansi:

2. TheUsage of NPTH

Kutholakala ukuthi i-actionture ye-NPTH imvamisa inkulu kune-pth, ngoba i-tyth isetshenziswa kakhulu njengesikulufa sokukhiya, kanti eminye isetshenziselwa ukufaka ukuxhumana okuthile ngaphandle kwesixhumi esilungisiwe. Ngaphezu kwalokho, ezinye zizosetshenziswa njengokulungiswa kokuhlola ohlangothini lwepuleti.

3. Ukusetshenziswa kwe-PTH, yini nge-via?

Ngokuvamile, izimbobo ze-pth ebhodini lesekethe zisetshenziswa ngezindlela ezimbili. Eyodwa isetshenziselwa ukufudumeza izinyawo zezingxenye zendida zendabuko. Ukuthambekela kwalezi zimbobo kumele kube kukhulu kunesilinganiso sezinyawo ze-welding zezingxenye, ukuze izingxenye zifakwe ezitsheni.

Enye into encane, evame ukubizwa nge (Hole Dollerction Hole), isetshenziselwa ukuxhuma kanye ne-PCB) phakathi kwezendlalelo ze-topper (i-PCB) kuzokuthi, ungqimba lwethusi luzokwazi ukuxhumeka komunye nomunye, okushiwoyo "Dlula ngomgodi" ngesiShayina. Nge-Ngenxa yokuthi izimbobo azibonakali ngokuphelele ngaphandle. Ngoba inhloso ye-Via ukwenza i-foil ye-Copper yezendlalelo ezahlukene, kudinga i-electroplating ibe yinto yokuziphatha, ngakho-ke nge-via futhi iluhlobo lwept.
