Ke lumela hore metsoalle e mengata e tla ts'oareha haholo ha u khetha reflow soldering.Ha ba tsebe ho khetha, haholo-holo metsoalle e sa tsebeng reflow soldering e ferekanngoa le ho feta.Se tshwenyehe jwale.Ha re ke re tsebise ka bokhutšoanyane mokhoa oa ho e etsa.Khetha mokhoa oa ho reflow soldering:
1. Sheba ts'ebetso ea ho kenya letsoho ea ontong ea reflow.
Ovine ea boleng bo holimo e na le phello e ntle ea ho boloka mocheso le ts'ebetso e phahameng ea mocheso, empa onto e tlaase ea reflow ha e na mosebetsi o joalo.Le hoja ho le thata ho lekanya katleho ea mocheso oa ontong ea reflow, o ka ama setofo sa reflow le moea oa ho ntša moea ka letsoho.Ha pipeline e sebetsa, khetla e sebelisetsoa ho ahlola mocheso.Haeba u ikutloa u chesa ha u e tšoara ka matsoho kapa u se ke ua iteta sefuba ho e tšoara, ho bolela hore ts'ebetso ea ho kenya letsoho ea sebōpi e fokola 'me tšebeliso ea matla e kholo.Ka tloaelo, letsoho la motho le utloa le chesa hanyenyane (hoo e ka bang likhato tse 50 tsa Celsius).
2. Mofuta oa heater: Lifuthumatsi li ka aroloa ka mabone a infrared le li-heaters tsa mabone tse feto-fetohang.
(1) Tubular heater: E na le melemo ea mocheso o phahameng oa ho sebetsa, bolelele ba mahlaseli a makhutšoane le karabelo e potlakileng ea mocheso.Leha ho le joalo, ka lebaka la ho hlahisa leseli nakong ea ho futhumatsa, e na le liphello tse fapaneng tsa ho bonahatsa likarolo tsa welding tsa mebala e fapaneng.Ka nako e ts'oanang, ha e tšoanelehe ho lumellana le moea o chesang o qobelloang.
(2) Sefuthumatsi sa poleiti: Karabelo ea mocheso e tsamaea butle mme ts'ebetso e tlase hanyane.Leha ho le joalo, ka lebaka la inertia e kholo ea mocheso, ho phunyeha ho loketse ho futhumatsa moea o chesang.Ha e nahane ka 'mala oa likarolo tse cheselitsoeng' me e na le phello e nyenyane ea moriti.Ho phaella moo, hona joale ho rekisoa Liotong tsa reflow, li-heaters ke hoo e batlang e le lipoleiti tsohle tsa aluminium kapa licheso tsa tšepe tse sa hloekang.
3. Sistimi ea ho fetisa mocheso ea reflow soldering e tlameha ho ba le libaka tse 4 ho isa ho tse 5 tsa ho futhumatsa.
Good reflow soldering e na le bonyane heater sebakeng sa preheating, 'me e ka laola ka boikemelo mocheso ho etsa bonnete ba hore mocheso o ka fetisoa ka potlako ho mocheso oa soldering ka litsela tse tharo: conduction, convection, le radiation.
Lintlha tse ka holimo li mabapi le mokhoa oa ho reflow soldering.Ha re khetha reflow soldering, re ka bapisa ho ea ka lintlha tse ka holimo.Ka nako e ts'oanang, re boetse re hloka ho khetha mofuta oa solder ea reflow ho latela litlhoko tsa rona.Ke tšepa hore e ka thusa bohle.
