Goridhe Finger: (Gold Finger kana Edge Connector) Isa imwe mugumo we Pcb bhodhi mukati meiyo yekubatanidza kadhi slot, uye shandisa pini yekubatanidza sekubuda kwepcb board kuti ubatanidze kune kunze, kuitira kuti padhi kana ganda remhangura ribatane nepini panzvimbo inoenderana Kuti uwane chinangwa chekufambisa, uye nickel. -goridhe rakaputirwa paden iri kana ganda remhangura repcb board, rinonzi chigunwe chegoridhe nekuti chiri muchimiro chemunwe. Ndarama yakasarudzwa nekuda kwepamusoro conductivity uye oxidation kuramba. Abrasion resistance. Zvakadaro, nekuda kwekudhura kwakanyanya kwegoridhe, rinongoshandiswa pakunamira goridhe seminwe yegoridhe.

Goridhe kupatsanurwa kwemunwe uye kuzivikanwa, maitiro

Cheat classification: kubiridzira kwakajairwa (zvigunwe zvekugezesa), cheats refu uye pfupi (kureva, kubiridzira kusina kuenzana), uye cheats yakakamurwa (kubiridzira kwepakati).

1. Zvigunwe zvegoridhe zvakajairika (zvigunwe zvinoputika): mapedhi ane rectangular ane urefu hwakafanana uye hupamhi anorongwa zvakanaka pamucheto webhodhi. Mufananidzo unotevera unoratidza: makadhi etiweki, makadhi emifananidzo uye mamwe marudzi ezvinhu zvemuviri, ane zvimwe zvigunwe zvegoridhe. Mamwe mahwendefa madiki ane zvigunwe zvegoridhe zvishoma.

2. Zvigunwe zvegoridhe zvirefu uye zvipfupi (kureva zvigunwe zvegoridhe zvisina kuenzana): mapedhi ane rectangular ane urefu hwakasiyana pamucheto webhodhi 3. Zvigunwe zvegoridhe zvakakamurwa (zvigunwe zvegoridhe zvinopinda): mapedhi ane rectangular ane urefu hwakasiyana pamucheto webhodhi, uye iyo chikamu chepamberi bvisa.

Iko hakuna chimiro uye chinyorwa, uye inowanzova solder mask yekuvhura hwindo. Zvimiro zvizhinji zvine grooves. Chigunwe chegoridhe chikamu chinobuda kubva kumucheto kwebhodhi kana kuti iri pedyo nemucheto webhodhi. Mamwe mapuranga ane zvigunwe zvegoridhe kumativi ose maviri. Zvigunwe zvegoridhe zvakajairika zvine mativi ese, uye mamwe mabhodhi epcb ane zvigunwe zvegoridhe zvine divi rimwe chete. Zvimwe zvigunwe zvegoridhe zvine mudzi mumwe wakafara.

Parizvino, iyo inowanzo shandiswa yegoridhe gilding process inonyanya kusanganisira anotevera marudzi maviri:

Imwe ndeyekutungamirira kubva kumagumo emunwe wegoridhe sewaya yakaputirwa negoridhe. Mushure mekunge kuputirwa kwegoridhe kwapera, mutobvu unobviswa nekugaya kana kuti etching. Zvisinei, zvigadzirwa zvinogadzirwa nemhando iyi yemaitiro zvichange zviine masara emutobvu zvakatenderedza zvigunwe zvegoridhe, zvichikonzera kuratidzwa kwemhangura, iyo isingakwanisi kusangana nezvinodiwa zvekusabvumira kuratidzwa kwemhangura.

Imwe yacho ndeyekutungamirira waya kwete kubva kuminwe yegoridhe, asi kubva mukati kana kunze kwemukati mebhodhi redunhu rakabatanidzwa kune zvigunwe zvegoridhe kuti uwane goridhe rakapfekedzwa zvigunwe zvegoridhe, nekudaro kudzivirira kubuda kwemhangura pazvigunwe zvegoridhe. Zvisinei, kana dhizaini yebhodhi yedunhu yakakwira zvikuru uye dunhu racho rakanyanyisa, iyi nzira inogona kusakwanisa kuita zvinotungamirira munharaunda yedunhu; uyezve, chirongwa ichi hachina simba kune zvigunwe zvegoridhe zvega (kureva kuti, zvigunwe zvegoridhe hazvina kubatana nedunhu).
