Sarrafa Masana'antu da Inganci

Samar da shafuka masu aiki mai kyau yana buƙatar daidaito:

1. Tsarin rufi: Shafukan jan ƙarfe da aka yi da nickel suna amfani da electroplating (kauri 1.8±0.3μm) ko electroplating (kauri 1.0±0.3μm) don tabbatar da daidaiton rufewa.
2. Gyara gefen: Zaren ƙarfe masu kauri fiye da 0.2mm suna buƙatar a yanke gefen don guje wa matsalolin rufi da haɗarin zubewa.
3. Gwaji mai tsauri:
   1. Gwaje-gwajen nutsewa ta hanyar electrolyte: Shafuka dole ne su kasance da ƙarfin rufewa >15N/15mm bayan awanni 24 a zafin 85°C.
   2. Gwaje-gwajen lanƙwasa: Dole ne shafuka su jure lanƙwasawa sau 5-7 (ya danganta da kauri) don tabbatar da dorewa a cikin yanayin girgiza (misali, motocin lantarki).

Hanyoyin Haɗin Shafi

Haɗa shafuka zuwa da'irorin waje ya ƙunshi dabaru da dama:

1. Maƙallin injina: Hakowa da ƙulle-ƙulle suna ba da haɗin kai mai rahusa da ƙarfi amma suna buƙatar kulawa mai kyau game da kauri.
2. Haɗin gwiwa: Na'urar solder mai ƙarancin zafin jiki M51 tana aiki ga ƙarfe daban-daban (misali, jan ƙarfe da aluminum) amma tana da tsada.
3. Walda ta Ultrasonic: Hanya mafi dacewa don batirin wutar lantarki, ta amfani da girgiza mai yawan mita don haɗa siririn foil ɗin shafi (0.01mm) ba tare da zafi mai yawa ba.

Kammalawa

Shafukan na iya zama ƙanana, amma ƙirarsu da ingancinsu suna shafar aikin batirin jaka kai tsaye. Yayin da buƙata ke ƙaruwa don aminci da inganci a cikin motocin lantarki da adana makamashi, ci gaba a cikin kayan tabs (misali, manne mai layuka da yawa) da kera (misali, sanyaya daidai) zai kasance mai mahimmanci. Fahimtar halayen tabs shine mabuɗin inganta amincin baturi da tsawon rai a aikace-aikace daban-daban.
