Zvinogona kucherechedzwa kuti kune akawanda maburi makuru uye madiki mudunhu mudunhu, uye zvinogona kuwanikwa kuti kune maburi mazhinji emawere, uye gomba rimwe nerimwe rakagadzirirwa chinangwa chayo. Aya maburi anogona kukamurwa muPth (pleting kuburikidza negomba) uye npth (vasingatenderi kuburikidza negwenzi "

PCB Mitemo: Kuburikidza negomba, gomba bofu, rakavigwa gomba.

1. Sei kusiyanisa pth uye npth mumakomba?

Inogona kutongwa kana paine inopenya yemagetsi mavara emadziro pamadziro egomba. Gomba rine ma electroplating mamaki ndeye pth, uye gomba risina magetsi emagetsi aripo npth. Sezvinoratidzwa mumufananidzo uri pazasi:

2. TheUSage yeNPTH

Izvo zvinowanikwa kuti kupatsanurwa kweNPTH Kazhinji kupfuura pth, nekuti nPth zvinonyanya kushandiswa sekiya yekukiya, uye zvimwe zvinoshandiswa kuisa zvimwe kubatana kunze kwechinguvana yakatarwa. Mukuwedzera, vamwe vachashandiswa seyekuongororwa bvunzo parutivi rweplate.

3. Kushandiswa kwePth, chii chinonzi?

Kazhinji, pth maburi pane redunhu board anoshandiswa munzira mbiri. Imwe inoshandiswa kumanikidza tsoka dzetsika dzechinyakare. Kuwedzeredzwa kweaya maburi anofanirwa kunge akakura kupfuura dhayisiti yemakumbo ezvikamu, zvekuti mitezo yakaiswa mumakomba.

Chimwe chidiki pth, chinowanzodaidzwa kubiridzira "Pfuura kuburikidza negomba" muchiChinese. Kuburikidza nekuti maburi haana zvachose kubva kunze. Nekuti chinangwa che kuburikidza neye kuitisa mhangura foil yezvikamu zvakasiyana, zvinoda Electroplating kufambiro, saka kuburikidza zvakare nerudzi rwePth.
