1, Phom pob
(1) Before luam ntawv, ham muab tshuaj tsis tau tag nrho ua kom sov yaj thiab do ua kom sib npaug.
(2)Tom qab luam ntawv rau ntev ntev yam tsis muaj reflow, cov kuab tshuaj evaporates, thiab cov tshuaj txhuam ua cov hmoov qhuav thiab poob rau hauv tus number case.
(3)Kev luam ntawv yog tuab heev, thiab qhov muab tshuaj txhuam kom ntau dhau lawm tom qab qhov cuam tshuam raug nyem cia.
(4)Qhov kub nce siab heev thaum lub sij hawm REFLOW (SLOPE> 3), ua rau cov menyuam pob.
(5)Lub siab mounting dhau dhau lawm, thiab hauv qab qis siab ua rau cov ham tsis zoo rau lub vau.
(6)Kev cuam tshuam rau ib puag ncig: huab cua ntau dhau, ib txwm kub 25+ / -5, av noo 40-60 %, nce txog 95 % thaum nws los nag, dehumidification yog qhov yuav tsum tau ua.
(7)Cov duab ntawm lub ncoo qhib tsis zoo, thiab tsis muaj kev tiv thaiv kev tiv thaiv kev tiv thaiv kev ua tiav.
(8)Cov kev ua ntawm solder muab tshuaj yog qhov tsis zoo, nws dries nrawm dhau, los yog muaj tin ntau dhau nrog cov hmoov me me.
(9)Cov muab tshuaj txhuam zeem rau yog ua rau lub chaw oxidizing ntev heev thiab nqus cov dej noo hauv huab cua.
(10)Tsis txaus preheating, dhau lawm qeeb thiab tsis txaus cua sov.
(11)Luam tawm offset, kom ib feem ntawm cov ham muab tshuaj txhuam rau cov PCB.
(12)Kev ceev scraper yog nrawm heev, ua rau muaj kev sib tsoo tsis zoo tom qab thiab pob pob tom qab reflow.
(13)Qhov lub taub ntawm pob solder yuav tsum tsawg dua 0.13MM, los yog tsawg dua 5 hauv 600 square millimeters.
