Solder, sechinhu chinobatanidza zvinhu munzvimbo dzakawanda dzakadai semagetsi, mota, ndege, nezvimwewo, hunhu hwayo uye mashandiro ayo zvinokanganisa zvakananga kuvimbika nekugadzikana kwezvigadzirwa. Nekufambira mberi kwetekinoroji, zvinodiwa zvekuchena, magadzirirwo emukati, uye mashandiro esolder zviri kuramba zvichikwira. Semuchina wepamusoro wesimbi wekukanda, muchina wevacuum unotenderera wakabata zvishoma nezvishoma wakakwezva kutariswa muindasitiri yekukanda, zvichipa mhinduro inoshanda yekugadzira solder yemhando yepamusoro.

1、Musimboti wekushanda weVacuum chinjikira kuramba vachikanda muchina

Muchina wekukanda unochinjika unochinjika unonyanya kugadzirwa nechoto, crystallizer, mudziyo wekudhonza billet, system yekubvisa mvura, nezvimwe zvikamu. Kutanga, isa zvinhu zvinosungirirwa muchoto chinonyunguduka wozvipisa kuti zvisvike pakupisa kwemvura kwakakodzera. Zvadaro, nzvimbo yekukanda inobviswa kusvika pamwero wakati kuburikidza nesystem yekubvisa mvura kuti kuderedze kusanganiswa kwetsvina yegesi. Pasi pesimba regiravhiti nekumanikidzwa kwekunze, solder yemvura inoyerera ichipinda mu crystallizer yakaiswa yakatwasuka, iyo inotonhodzwa nemvura inotenderera kuti iome zvishoma nezvishoma uye iome pamadziro ayo emukati, zvichiita goko. Nekudhonza zvishoma nezvishoma kwemudziyo wekukanda, solder itsva yemvura inoramba ichizadzwa mu crystallizer, uye goko re solder rakasimba rinoburitswa nguva dzose, nokudaro zvichiita maitiro ekukanda nguva dzose.

Vacuum chinjikira kuramba vachikanda muchina

2、Mabhenefiti eMuchina weVacuum Horizontal Continuous Casting

()1）Kuvandudza kuchena kwe solder

Kukanda zvinhu munzvimbo isina chinhu kunogona kudzivirira kusvibiswa kwemagasi akadai seokisijeni nenitrogen kupinda musolder, kuderedza kuumbwa kwe oxide inclusions nema pores, kunatsiridza zvakanyanya kuchena kwesolder, uye kunatsiridza kunyorova kwayo uye kufamba kwayo zvakanaka panguva yekusveta, nokudaro zvichivandudza mhando yesolder yakasveta.

()2）Kuvandudza magadzirirwo emidziyo ye solder

Munguva yekukanda zvinhu zvakachinjika zvakachinjika, mwero wekusimba kwemuchina wekusonesa mvura wakaenzana, uye mwero wekutonhodza unodzoreka, izvo zvinobatsira kugadzira chimiro chakafanana uye chegorosi rakatsetseka uye kuderedza kupatsanurwa. Chimiro ichi chakafanana chehurongwa chinoita kuti hunhu hwemuchina wekusonesa huve hwakagadzikana, senge simba rekusimba uye kureba, izvo zvinovandudzwa uye zvinosangana nezvimwe zviitiko zvinoda kushandiswa kuti sonesa ishande zvakanaka.

()3）Kugadzirwa kunoshanda nguva dzose

Zvichienzaniswa nenzira dzechinyakare dzekukanda, michina yekukanda inochinjika inochinjika inogona kugadzira zvinhu zvinoenderera mberi uye zvisingachinji, zvichivandudza zvikuru mashandiro ekugadzira. Panguva imwe chete, ine mwero wepamusoro wekuzvigadzira otomatiki, ichideredza matanho ekushanda nemaoko, ichideredza simba revashandi nemari yekugadzira, uye inoita kuti maitiro ekugadzira ave akasimba uye akavimbika, izvo zvinoita kuti pave nekudzora kunaka kwechigadzirwa nguva dzose.

()4）Deredza marara ezvinhu zvisina kugadzirwa

Nekuda kwemaitiro ekukanda anoramba achienderera mberi uye kutonga kwakaringana kwehukuru nechimiro chebhillet, zvichienzaniswa nedzimwe nzira dzekukanda, inogona kushandisa zvinhu zvakabikwa zvinobudirira, kuderedza marara ezvinhu anokonzerwa nekucheka, mvumo yemichina, nezvimwewo, kuvandudza mwero wekushandiswa kwezvinhu zvakabikwa, uye kuderedza mari yekugadzira.

3、Mashandisirwo chaiwo muindasitiri yekusonesa

()1）Maitiro ekugadzira

Mukugadzira solder, danho rekutanga nderekusanganisa zvinhu zvinodiwa zve solder uye kuwedzera zvinhu zvakagadzirwa muchoto chemuchina we vacuum unochinjika unochinjika. Tanga sisitimu ye vacuum, deredza kumanikidzwa mukati mechoto kusvika padanho rakakodzera re vacuum, kazhinji pakati pemakumi e pascals nemazana e pascals, wobva wapisa nekunyungudutsa solder wochengetedza tembiricha yakagadzikana. Gadzirisa kumhanya kwekukanda uye huwandu hwemvura inotonhorera ye crystallizer kuti uve nechokwadi chekuti solder yemvura inonamira zvakaenzana mu crystallizer uye inoburitswa nguva dzose, zvichiita kuti pave netsananguro yakati ye solder billet. Bleak inogadziriswa kuburikidza nematanho anotevera ekumonera, kudhirowa uye mamwe ekugadzirisa kuti pagadzirwe maumbirwo akasiyana-siyana uye matsananguro ezvigadzirwa zve solder, zvakaita se welding wire, welding strip, solder paste, nezvimwewo, kuti zvisangane nezvinodiwa zve welding zveminda yakasiyana.

()2）Kuvandudza mhando yezvinhu zvinosungirirwa

Tichitora Sn Ag Cu solder isina lead inowanzoshandiswa muindasitiri yemagetsi semuenzaniso, kana yakagadzirwa uchishandisa muchina wevacuum horizontal continuous casting, huwandu hweokisijeni mu solder hunogona kudzorwa zvakanyanya padanho rakaderera, kudzivirira kusvibiswa kwakadai se tin slag inokonzerwa ne oxidation uye kuvandudza mwero wekushandiswa kwakanaka kwe solder. Panguva imwecheteyo, chimiro chakafanana chesangano chinogonesa solder kuzadza zviri nani mipata midiki ye solder panguva ye micro soldering process ye electronic components, kuderedza zvikanganiso zve welding zvakaita se virtual soldering and bridgeing, uye kuvandudza kuvimbika kwe welding uye mashandiro emagetsi ezvigadzirwa zvemagetsi.

Mukushanda kwesimbi yekuputira muindasitiri yemotokari, kune solder ine simba guru rakagadzirwa nearuminiyamu, solder inogadzirwa nemuchina wekuputira unochinjika une simba riri nani uye unodzivirira ngura. Chimiro chayo chezviyo zvakafanana chinovimbisa kugadzikana kwesimbi yekuputira panguva yekuputira inodziya zvakanyanya, iyo inogona kubatanidza zvikamu zvemotokari zvakasimba uye kuvandudza mashandiro ese uye hupenyu hwebasa rezvikamu zvemotokari.

()3）Mienzaniso yekushandisa

Kambani inozivikanwa yekugadzira solder yakaunzamuchina wekudzikisa simbi unoenderera mberi, izvo zvakawedzera kuchena kwezvigadzirwa zvayo zve tin lead solder kubva pa98% kusvika pamusoro pe99.5%, uye zvakaderedza zvakanyanya huwandu hwe oxide inclusions. Mukushandiswa kwe welding kwema electronic circuit boards, mwero we welding failure wakaderera kubva pa5% kusvika pasi pe1%, zvichivandudza zvikuru kukwikwidzana kwechigadzirwa pamusika. Panguva imwe chete, nekuda kwekuvandudzwa kwekushanda zvakanaka kwekugadzira uye kudzikiswa kwemarara ezvinhu zvakabikwa, mutengo wekugadzira webhizinesi waderedzwa neinenge 15%, zvichiwana mabhenefiti akanaka ehupfumi nemagariro.

4、Tarisiro yebudiriro

Nekukurumidza kukura kwemaindasitiri akadai semagetsi, simba idzva, uye kugadzira michina yepamusoro-soro, zvinodiwa zvemhando yepamusoro uye mashandiro emidziyo yekusolder zvicharamba zvichiwedzera. Muchina wekusolder unochinjika une mikana yakawanda yekushandisa muindasitiri yekusolder nekuda kwezvakanaka zvawo zvakasiyana. Mune ramangwana, nekufambira mberi kuri kuitwa tekinoroji yekugadzira michina, sisitimu yawo yekusolder ichave inoshanda uye yakagadzikana, mwero wekudzora otomatiki uchawedzerwa, uye kutonga kwakanyatsojeka kwema process parameter kunogona kuwanikwa, zvichigadzira zvigadzirwa zvemhando yepamusoro uye zvakagadzirwa nemunhu. Panguva imwecheteyo, nezvinodiwa zvakanyanya zvezvakatipoteredza, mabhenefiti emuchina wekusolder unochinjika wevacuum mukuderedza kushandiswa kwesimba uye kusvibiswa kwemhepo kuchaitawo kuti ive tekinoroji yakakosha yekusimudzira indasitiri yekusolder.

5、 Mhedziso

Kushandiswa kwemuchina wekukanda unochinjika unochinjika muindasitiri yekusona kunopa vimbiso yakasimba yekugadzira solder yemhando yepamusoro uye inoshanda zvakanyanya. Nekuvandudza kuchena kwesolder, kusimbisa chimiro chesangano, kuwana kugadzirwa kunogara kuripo, uye kuderedza mitengo, kudiwa kuri kuwedzera kwesolder muindasitiri yemazuva ano kwasangana. Nekuvandudzwa nekugadziriswa kwetekinoroji kunoramba kuripo, kushandiswa kwayo muindasitiri yekusona kuchawedzera uye kwakadzika, zvichikurudzira kukura kweindasitiri yekusona kune mhando yepamusoro, kushanda kwepamusoro, uye kuchengetedzwa kwezvakatipoteredza kwakasvibirira, zvichipa zvinhu zvekubatanidza zvemhando yepamusoro uye zvakavimbika kune maindasitiri mazhinji anovimba nekubatanidza solder, uye kukurudzira kuvandudzwa kwetekinoroji uye kufambira mberi kwecheni yese yeindasitiri.

Mukufambira mberi kweindasitiri yekusonesa mune ramangwana, mabhizinesi anofanirwa kuziva zvizere kugona uye kukosha kwemuchina wekukanda unoenderera mberi wevacuum level, kutanga nekushandisa tekinoroji iyi yepamusoro, kusimbisa hunyanzvi hwetekinoroji uye kugadzirisa maitiro, kuramba vachivandudza kukwikwidzana kwavo mumusika, uye kusimudzira pamwe chete indasitiri yekusonesa kuti iende padanho idzva rekukura.
