Welding is SMT chip process process is anokosha link, kana mune iyi link yakaratidza zvikanganiso zvinokanganisa zvakananga chip processing redunhu bhodhi rakatadza uye rakaraswa, saka mukushongedza kunoda kubata nzira chaiyo yewelding, kunzwisisa nyaya dzakakodzera dzekutarisa kuti udzivise. matambudziko.
1. mukugadzirisa chip kusati kwave kusungirirwa pamapedhi akaputirwa ne flux, uchishandisa simbi yekunyungudutsa kubata nayo kamwe chete, kudzivirira mapedhi asina kuvharwa zvakanaka kana kuti oxidized, kuumbwa kwehuipi hwakaipa, chip hachiwanzofanira kutarisana nacho. .
2. Shandisa tweezers kunyatsoisa PQFP chip paPCB board, teerera kuti usakuvadza mapini.Gadzirisana nemapedhi uye ita shuwa kuti chip yakaiswa munzira kwayo.Isa tembiricha yesimbi inotengeswa inopfuura 300 madhigirii celsius, nyudza muromo wesimbi muchikamu chidiki chekutengesa, dzvanya pasi pane chip nechishandiso chakamisikidzwa pachinzvimbo, wedzera zvishoma solder kune mapini maviri ane diagonally positioned, achiri kudzvanya pasi pachip uye tengesa mapini maviri ane diagonally positioned kuitira kuti chip chigadzirwe uye chisakwanise kufamba.Mushure mekutengesa diagonal, tarisa nzvimbo ye chip kubva pakutanga kuti uone kana yakabatana.Kana zvichidikanwa, gadzirisa kana bvisa uye gadzirisa chinzvimbo paPCB kubva pakatanga.
3. Tanga welding mapini ose, unofanira kuwedzera solder kumucheto wesimbi yesimbi, mapini ose achaputirwa ne solder kuitira kuti mapini anonamatira kumvura.Bata kumucheto kwepini yega yega yechip nemuromo wesimbi inotengeswa kusvika waona solder ichiyerera mumapini.Paunenge uchitengesa, namatira kumucheto wesimbi yekunyungudutsa uye mapini akatengeswa anoenderana kuti usapindirana nekuda kwekunyanyisa solder.
4. Mushure mekutengesa mapini ose, nyorovesa mapini ose ne solder kuitira kuti uchenese solder.Z mushure mekushandisa tweezers kutarisa kana pane nhema solder, tarisa kupedzwa, kubva redunhu bhodhi rakaputirwa nekuyerera, zvichava nyore kune SMD resistive components solder vamwe, unogona kutanga mune solder point patin, wozopfeka imwe mugumo wechikamu, ine tweezers yekubata chikamu, solder kune rumwe rutivi, uye zvino ona kana yaiswa zvakanaka;kana zvakarukwa zvakanaka, solder pane imwe Kana zviri izvo, solder mumwe mugumo.Kudzidzira kwakawanda kunodiwa kuti unyatsobata hunyanzvi hwekusodha.
Zvimiro zveNeoDen IN12Creflow oven
1. Built-in welding fume filtration system, kusefa kunobudirira kwemagasi anokuvadza, kutaridzika kwakanaka uye kuchengetedzwa kwezvakatipoteredza, zvakanyanya maererano nekushandiswa kwepamusoro-soro.
2. Iyo yekudzora sisitimu ine hunhu hwekubatanidzwa kwepamusoro, kupindura panguva yakakodzera, kuderera kwekutadza mwero, nyore kuchengetedza, nezvimwe.
3. Kushandiswa kwepamusoro-inoshanda aluminium alloy inopisa ndiro panzvimbo yekupisa chubhu, zvose zvinoponesa simba uye zvinobudirira, zvichienzaniswa nemafuta anoyerera akafanana pamusika, kutsauka kwekushisa kwemashure kunoderedzwa zvakanyanya.
4. Kupisa kwekudzivirira kuchengetedza dhizaini, kutonhora kwegomba kunogona kudzorwa zvakanaka.
5. Intelligent control, high-sensitivity tembiricha sensor, inoshanda kudzikamisa tembiricha.
6. Tsika-yakagadziridzwa track drive mota zvinoenderana nehunhu hweB-mhando mesh bhandi, kuve nechokwadi chekumhanya kweyunifomu uye hupenyu hurefu.
