Seo re Lokelang ho se Tseba ka "Tinning Rods"

Litlhoko tsa boitokiso le boleng ba lithupa tsa tinning/strips

Tin rod, joalo ka ha lebitso le bolela hore ke rod solder, e bitsoa indasteri ea tin rod. Haholo-holo e sebelisetsoang ho solder le ho qoelisoa ka metsi, hona joale ke tšebeliso e kholo ka ho fetisisa ea mefuta e sa tšoaneng ea solder ea elektronike; chelete e nyane e boetse e sebelisoa bakeng sa ho chesoa ha lelakabe kapa tšepe ea soldering ea likarolo tse kholo tsa sebopeho le li-welds tse telele. Ke sesebelisoa sa bohlokoahali se hokahanyang lihlahisoa tsohle tsa elektroniki le tsa motlakase mme tšebeliso ea selemo le selemo ea lefats'e e ka ba lithane tse 100,000.

Mokhoa oa ho lokisa oa tin strip o bonolo, ho kenyelletsa le batching, ho qhibiliha le ho lahlela, 'me tekanyo ea oxidation le litaba tsa litšila tsa tšepe le tse seng tsa tšepe li laoloa ka thata. Thempereichara ea ho qhibiliha le mocheso oa ho lahlela li na le tšusumetso e kholo boleng ba thini. Ho lokisoa ha likhoele tsa tin ho bonolo 'me moeli oa tekheniki o tlase, kahoo tlholisano e matla haholo. Theko ea hona joale e eketsa feela tefiso e fokolang ea ho sebetsa litšenyehelong tsa thepa e tala. Hang ha theko ea thepa e tala e feto-fetoha haholo ka nako e khutšoanyane, phaello e fokolang e ka 'na ea felisoa, kapa esita le tahlehelo.

Litlhoko tsa mantlha tsa boleng ba tin strip ke tse latelang:

(1) Bokaholimo ba lesela le boreleli;

(2) Mokelikeli o motle le ho ba metsi nakong ea ho cheselletsa;

(3) Lintho tse ntle tsa mochine;

(4) Lenonyeletso le khanyang la solder;

(5) Masala a fokolang a oxidation.

Litšitiso tse atileng holim'a lesela la thini ke matheba a lipalesa le lipululana. Litšitiso tsena li bakoa ke mokhoa oa tlhahiso le tšebeliso ea hlobo. Ka mohlala, ha ho na sebaka sa ho senya nakong ea tlhahiso, tsamaiso ea ho pholile ha e ntle, 'me hlobo ha e boreleli, e leng se tla lebisa mathateng a ka holimo. Sesosa sa ho phatloha ho amana le boemo ba leholimo boo bo entsoeng ho bona. Basebeletsi ba tlhahiso ba nka bareng ea thini, ba se ke ba sebelisa letsoho ka kotloloho, mongobo o letsohong o tla ama khanya ea tin bar, phetolelo ea tin bar ea tšebeliso e ntle ea pampiri ea polasetiki, ka bobeli e ka bona khanya, eseng mongobo. Ha nako ea polokelo e le telele kapa sebaka sa polokelo se le mongobo haholo, ho tla ba le lera la oxide holim'a lesela la tin, le tla etsa hore khanya ea lesela la tin e time, empa e na le phello e fokolang ts'ebetsong ea ts'ebeliso. .

Ho aroloa ha li-tin strips:

Lithapa tsa masenke li arotsoe ka tšireletso ea tikoloho, ho kenyeletsoa likhoele tse nang le loto le likhoele tse se nang loto.

Hona joale, marapo a tloaelehileng a sebelisoang a se nang loto ke: thini ea koporo e se nang lead tin strip (Sn99.3Cu0.7), tin strip ea koporo e se nang lead (Sn96.5Ag3.0Cu0.5), 0.3 silver lead- mahala tin strip (Sn99Ag0.3Cu0.7), mocheso o phahameng oa mofuta oa lead-free tin strip (SnSb).

The ka tloaelo sebelisoa lead tin eleketrode haholo-holo e akarelletsa: 63/37 solder bareng (Sn63/Pb37), 60/40 solder bareng (Sn60/Pb40) le phahameng mocheso solder bareng (400 likhato ka holimo tjheseletsa).

Ho phaella linthong tse ka sehloohong tsa thini, lead, koporo, silevera, hangata li na le lintho tse ling tse nyenyane, tse kang nickel, antimony, bismuth, in, lefatše le sa tloaelehang joalo-joalo.

Lintho tsena tse nyane tsa alloy strip tin li na le tšusumetso e kholo ho thepa ea 'mele le mochini oa tin strip: bismuth e ka fokotsa mocheso o qhibilihang oa lesela le ho ntlafatsa ho kolobisa le ho hasa thepa, empa bismuth e ngata haholo e tla fokotsa bophelo ba mokhathala le polasetiki ea solder. manonyeletso, 'me palo e loketseng ea bismuth e ka bang 0.2 ~ 1.5%. Ni ka ntlafatsa thepa ea mechine le mokhathala bophelo ba manonyeletso solder ka ho fetola microstructure le ho hloekisa lijo-thollo. Moqapi o hlophisitsoeng oa sebopeho sa lik'hemik'hale, ho hlakile hore moqapi o tšepa hore lesela la tin le ka finyella tekanyo e nepahetseng likarolong tse fapaneng tsa ts'ebetso, tse kang ts'ebetso ea ho tjheseletsa, mocheso o qhibilihisang, matla, polasetiki le bophelo ba mokhathala, joalo-joalo.
