Ugcino lwesiqhelo kunye neenkcukacha zogcino olukhulu lwe-oveni yokuphinda igalelwe

Ukugcinwa okufanelekileyo rhoqo kwereflow oveninokwandisa ubomi benkonzo yeumatshini wokuphinda uphinde udibanise, qinisekisa ukusebenza okuqhelekileyo kwe-reflow soldering, kunye nokuphucula ukusebenza kakuhle kwemveliso kunye nomgangatho wemveliso.I-Reflow soldering ngaphambi kokuba ulungiso kufuneka lulungiselele isicoci se-vacuum, iphepha elingenathuli, ilaphu, ibrashi, ibrashi yentsimbi, i-agent yokucoca, i-agent yokucoca isithando somlilo, i-oyile yetsheyini yobushushu obuphezulu, i-oyile ye-anti-rust, utywala.

Ukugcinwa kwemihla ngemihla kweSMT reflow oven:

1. Coca inkangeleko ye-reflow soldering.Jonga ukuba imbonakalo ye-reflow soldering ingcoliswe luthuli.

2. Khangela i-oiler ezenzekelayo, khangela ukugcinwa kweoli ye-chain chain ephezulu kwi-oiler ezenzekelayo.

Xa i-oyile yetsheyini yobushushu obuphezulu kwi-oyile ingaphantsi kwe-1/3 yesikhongozeli, yongeza i-oyile yetsheyini yobushushu obufanelekileyo kwisikhongozeli.

3. Khangela ukuba ngaba kukho imizimba yangaphandle kumphezulu wokutshintsha kombane ekungeneni nasekuphumeni kwezothutho.

Isiqulatho sokugcinwa kwe-oveni kwakhona:

Misa i-oven yokuphinda uphume kwaye uphole kwiqondo lobushushu begumbi ngaphambi kokulungiswa.

1. Coca umbhobho wokukhupha: hlambulula ioli kwipayipi yokukhupha kunye ne-rag kunye ne-detergent.
2. coca uthuli lwe-drive sprocket: coca uthuli lwe-drive sprocket ngelaphu kunye notywala, uze uphinde ujoyine ioli yokuthambisa.Coca i-inlet kunye ne-outlet ye-reflow soldering, khangela ukuba kukho ioli okanye uthuli kwindawo yokungena kunye ne-outlet ye-reflow soldering, kwaye usule ucoceke nge-rag.
3. isicoci se-vacuum siya kuba kwi-furnace flux kunye nezinye i-adsorption engcolileyo.
4. ngelaphu okanye iphepha elingenathuli elifakwe kwisicoci somlilo liya kucoca isicoci asikwazi ukufunxa i-flux kunye nezinye izinto ezimdaka zosula.
5. lungisa utshintsho lokunyuswa kwesithando somlilo UKUVULA igesi yesithando somlilo, jonga ukuba indawo yokuphuma yomlilo kunye nomphezulu ugqunywe nge-flux kunye nezinye izinto ezibiweyo, kunye nefosholo yokuhlambulula izinto ezibiweyo, kwaye emva koko ucoce isicoci somlilo.
6. khangela i-Blower eshushu yomoya injini ephezulu nasezantsi ukuba kukho ukungcola kunye nemizimba yangaphandle, njengokungcola kunye nemizimba yangaphandle inokususwa ngokucoca i-detergent ngokukhawuleza emva kokususwa komhlwa.
7. Khangela ikhonkco lothumelo ukuze ubone ukuba i-deformation iyahambelana ne-gear, kwaye ingaba umngxuma phakathi kwekhonkco kunye nekhonkco ivalwe ngumzimba wangaphandle.Ukuba kukho ibrashi yentsimbi, inokususwa.
8. Jonga isikrini sokucoca kwindawo yokuphuma kunye nebhokisi yokukhupha, khupha ipleyiti yokutywina yangasemva yokungena kunye nebhokisi yokukhupha, khupha isikrini sokucoca, faka isikrini sokucoca kwi-solvent yokucoca, icoce ngebrashi yentsimbi, njalo njalo. kwi.Emva kokucocwa komphezulu wesikrini sokucoca, i-solvent ihlambuluke icocekile, faka isikrini sokucoca kwibhokisi yokukhupha, kwaye ufake ipleyiti yokutywina yebhokisi yokukhupha.
9. Khangela i-lubrication ye-reflow soldering rhoqo, njengeebheringi zentloko yomatshini kunye nekhonkco eyandisiweyo;Ikhonkco le-synchronous, ivili loxinzelelo kunye nokuthwala;Ikhonkco lothutho lwentloko phezu kokuthwala ivili;Isikrufu sentloko yomatshini kunye neebheringi zecala lokuqhuba.

Kufuneka kuqatshelwe ukuba ukuze ugweme ukucocwa ngokungafanelekanga kwesithando somlilo, okubangelwa ukutsha okanye ukuqhuma, kunqatshelwe ngokungqongqo ukusebenzisa i-solvents ephezulu yokucoca ukucoca ngaphakathi nangaphandle kwe-reflow solder.
