Birashobora kugaragara ko hari umwobo munini kandi muto kandi muto, kandi urashobora kuboneka ko hari umwobo mwinshi, kandi buri mwobo wateguwe kubwintego zayo. Izi mwobo zirashobora kugabanywa muri pth (gutoranya umwobo) na NPHT (idahwitse binyuze mu mwobo, kandi tukava mu mwobo mu kibaho mu kindi, kuko byanyuze mu mwobo mu kigo cy'akarere, kuko biri mu mwobo mu kibaho cy'akarere, mu kigo kiri mu kibaho cy'akarere.

Amagambo ya PCB: Unyuze mu mwobo, umwobo uhumye, umwobo washyinguwe.

1. Nigute ushobora gutandukanya Pth na NPH mu mwobo?

Irashobora gucirwa urubanza niba hari ibimenyetso byiza bya electraplating kurukuta. Umwobo ufite ibimenyetso bya electraplating ni Pth, n'umwobo udafite ibimenyetso bya electraplating ni NPTH. Nkuko bigaragara ku ishusho hepfo:

2..Uumunyabwenge npth

Biboneka ko aperture ya NPH iri nini kuruta pth, kuko npth ikoreshwa ahanini nkumugozi ufunze, kandi bimwe bikoreshwa mugushiramo amasano, kandi bimwe bikoreshwa mugushiramo amasano hanze yumuhuza hanze. Byongeye kandi, bamwe bazakoreshwa nkibizamini kuruhande rwisahani.

3. Imikoreshereze ya Pth, ni iki gikubiyemo?

Mubisanzwe, ibyobo byimyobo ya Pth kumuzunguruko bikoreshwa muburyo bubiri. Imwe ikoreshwa mugusumura ibirenge by'ibice gakondo. APERTure yizi myobo igomba kuba nini kuruta diameter yibirenge byuzuye byibice, kugirango ibice byinjizwe mu mwobo.

Ikindi gihe ugereranije na pth, mubisanzwe byitwa binyuze muri (umwobo wagiranye), ukoreshwa muguhuza ibice byikirere bibiri cyangwa byinshi byumuringa (umuringa) kidashobora gushyirwaho ikimenyetso cyikirere, kidashobora gushyirwaho ikimenyetso cyacyo, niyo mpamvu yitwa "kunyura mu mwobo" mu Gishinwa. Binyuze kuko ibyobo bitagaragara rwose hanze. Kuberako intego yakoreshejwe ni ugukora umuyoboro wumuringa wibice bitandukanye, bisaba kandi imyitwarire nayo ni ubwoko bwa pth.
