1. Mehato ea ts'ebetso eamochini oa solder.
1).Thepa ea solder ea maqhubuho lokisa pele ho tjheseletsa
Sheba hore na PCB e tla rekisoa e mongobo, hore na manonyeletso a solder a na le oxidized, a holofetse, joalo-joalo;phallo e amana le segokanyimmediamentsi sa sebolokigolo ea sprayer.
2).Ho qala ha lisebelisoa tsa wave soldering
Fetola bophara ba lebanta la mochini oa mochini oa solder (kapa sebopeho) ho latela bophara ba boto ea potoloho e hatisitsoeng;bulela matla le ts'ebetso ea fan ka 'ngoe ea mochini oa wave soldering.
3).Beha litekanyetso tsa ho tjheseletsa tsa lisebelisoa tsa wave soldering
Phallo ea Flux: Ho latela hore na phallo e kopana joang tlase ho PCB.Flux e hlokeha ho koaheloa ka ho lekana ka tlase ho PCB.Ho qala ho tloha ka lesoba ho PCB, ho lokela ho ba le phallo e nyane holim'a lesoba le phunyeletsang ho tloha ka lesoba ho ea ho pad, empa e sa kenelle.
Mocheso oa preheating: o behiloe ho latela boemo ba 'nete ba sebaka sa preheating sa ontong ea microwave (mocheso oa 'nete o kaholimo ho PCB hangata ke 90-130 ° C, mocheso oa poleiti e teteaneng ke moeli o kaholimo bakeng sa boto e kopaneng e nang le tse ling tse ngata. Likarolo tsa SMD, le moepa oa ho phahama ha mocheso o ka tlase ho kapa o lekana le 2°C/S;
Lebelo la lebanta la conveyor: ho ea ka mechini e fapaneng ea mochini oa solder le litlhophiso tsa PCB tse lokelang ho rekisoa (ka kakaretso 0.8-1.60m / min);mocheso oa solder: (e tlameha ho ba mocheso oa sebele oa tlhōrō o bontšitsoeng ho sesebelisoa (SN-Ag-Cu 260±5℃ , SN-Cu 265±5 ° C). Kaha mochine oa mocheso o ka har'a bateng ea tin, mocheso oa meter kapa LCD e ka ba 3 ° C holimo ho feta mocheso oa sebele oa tlhōrō;
Tekanyo ea bophahamo ba tlhoro: ha e feta tlase ho PCB, ikamahanya le 1/2 ~ 2/3 ea botenya ba PCB;
Welding angle: tšekamelo ea phetisetso: 4.5-5.5 °;tjheseletsa nako: ka kakaretso 3-4 metsotsoana.
4).Sehlahisoa se lokela ho rekisoa le ho hlahlojoa (ka mor'a hore litekanyetso tsohle tsa welding li fihle ho boleng bo behiloeng)
Ka bonolo beha boto ea potoloho e hatisitsoeng holim'a lebanta la conveyor (kapa sesebelisoa), mochini ka bohona o fafatsa likhopo, preheats, solders tsa wave le ho pholisa;boto ea potoloho e hatisitsoeng e hokahane ho tsoa ha solder ea wave;ho latela maemo a tlhahlobo ea feme.
5).Fetola li-parameter tsa welding ho latela liphetho tsa welding tsa PCB
6).Etsa tlhahiso e tsoelang pele ea ho tjheseletsa, hokela boto ea potoloho e hatisitsoeng sebakeng sa solder ea wave, e kenye ka lebokoseng la li-anti-static turnover ka mor'a tlhahlobo, 'me u romelle boto ea tlhokomelo bakeng sa ts'ebetso e latelang;nakong ea ts'ebetso e tsoelang pele ea tjheseletsa, boto e 'ngoe le e' ngoe e hatisitsoeng e lokela ho hlahlojoa, 'me mefokolo ea ho cheselletsa Liboto tse hatisitsoeng tse matla li lokela ho rekisoa hape hang-hang.Haeba ho ntse ho e-na le bofokoli ka mor'a ho cheselletsa, sesosa se lokela ho fumanoa, 'me welding e lokela ho tsoela pele ka mor'a ho lokisa mekhoa ea ts'ebetso.
2. Lintlha tsa ho ela hloko ts'ebetsong ea wave soldering.
1).Pele ho soldering ea wave, hlahloba boemo ba ts'ebetso ea lisebelisoa, boleng ba boto ea potoloho e hatisitsoeng e lokelang ho rekisoa le boemo ba plug-in.
2).Ha u ntse u etsa soldering ea wave, u lokela ho lula u ela hloko ts'ebetso ea lisebelisoa, hloekisa li-oxide ka holim'a bate ea tin ka nako, eketsa polyphenylene ether kapa oli ea sesame le li-antioxidants tse ling, 'me u tlatse solder ka nako.
3).Ka mor'a hore ho be le wave soldering, boleng ba welding bo lokela ho hlahlojoa block by block.Bakeng sa palo e nyane ea lintlha tse sieo tsa solder le bridging soldering, welding ea ho lokisa ka letsoho e lokela ho etsoa ka nako.Haeba ho na le palo e kholo ea mathata a boleng ba welding, fumana mabaka ka nako.
Wave soldering ke mokhoa o seng o hōlile oa indasteri oa soldering.Leha ho le joalo, ka palo e kholo ea likopo tsa lisebelisoa tsa holim'a holim'a holim'a metsi, ts'ebetso ea ho kopanya e tsoakiloeng ea lisebelisoa tsa plug-in le likarolo tsa holim'a holim'a metsi tse bokelitsoeng holim'a boto ea potoloho ka nako e le 'ngoe e fetohile mokhoa o tloaelehileng oa kopano lihlahisoa tsa elektronike, kahoo e fana ka mekhoa e mengata ea ts'ebetso. bakeng sa theknoloji ea wave soldering.E le ho finyella litlhoko tse thata, batho ba ntse ba tsoela pele ho hlahloba litsela tsa ho ntlafatsa boleng ba soldering ea wave soldering, ho akarelletsa le: ho matlafatsa taolo ea boleng ba boto ea potoloho e hatisitsoeng le likarolo pele ho soldering;ho ntlafatsa lisebelisoa tsa ts'ebetso tse kang flux le solder Taolo ea boleng;nakong ea tshebetso tjheseletsa, optimize tshebetso paramethara tse kang preheating mocheso, tjheseletsa pina tšekamelo, bophahamo leqhubu, mocheso tjheseletsa joalo-joalo.
