Mapangidwe a Reflow Oven

NeoDen IN6NeoDen IN6 Reflow uvuni

1. Reflow soldering uvunikayendedwe ka mpweya: kuthamanga kwambiri kwa mpweya, kuphatikizapo kuthamanga, kuyenda, fluidity ndi mphamvu yolowera.

2. SMT kuwotcherera makina Kutentha makina: moto mpweya wotentha, Kutentha chubu, thermocouple, olimba-boma relay, chipangizo chowongolera kutentha, etc.

3. Reflow soldering transmission system: kuphatikizapo njanji yowongoka, lamba wa mesh (thandizo lapakati), unyolo, magalimoto oyendetsa, kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake ndi mbali zina.

4. Reflow uvuniKuzirala: imatha kuziziritsa mwachangu PCB ikatenthetsa, nthawi zambiri m'njira ziwiri: kuziziritsa kwa mpweya ndi kuziziritsa kwamadzi.

5. Dongosolo la chitetezo cha nayitrojeni la reflow soldering: PCB ndi nayitrogeni wotetezedwa m'malo otenthetsera, malo owotcherera ndi malo ozizira munjira yonseyo, zomwe zingalepheretse oxidation ya solder olowa ndi zojambula zamkuwa pa kutentha kwakukulu, kumapangitsanso kunyowetsa kwachitsulo chosungunula. , kuchepetsa patsekeke mkati ndi kusintha khalidwe la solder olowa.

6. Reflow soldering flux kuchira unit: flux mu zinyalala dongosolo kuchira nthawi zambiri amakhala ndi evaporator, kudzera evaporator adzakhala utsi (kuwotcherera thandizo volatiles) usatenthedwe pamwamba 450 ℃, ndi flux kosakhazikika gasification, kenako madzi ozizira makina pambuyo madzi kuzirala kufalitsidwa. Pambuyo pa evaporator, kutuluka kwa mpweya kupyola mu fani chapamwamba, kupanga madzi oyenda kudzera mu evaporator yozizira kupita ku thanki yochira.

7. Reflow soldering zinyalala gasi mankhwala ndi kuchira chipangizo: cholinga cha mfundo zazikulu zitatu: zofunika kuteteza chilengedwe, musalole kusinthasintha volatiles mwachindunji kutulutsidwa mu mlengalenga;Kukhazikika ndi mpweya wa zinyalala mu kuwotcherera kudzakhudza kuyenda kwa mpweya wotentha ndikuchepetsa mphamvu ya convection, chifukwa chake iyenera kubwezeretsedwanso.Ngati kuwotcherera kwa nayitrogeni kwasankhidwa, kuti mupulumutse nayitrogeni ndikubwezeretsanso nayitrogeni, makina otulutsa mpweya wotulutsa mpweya ayenera kukhala ndi zida.

8. Chida chokwezera mpweya cha reflow kuwotcherera kapu: ndikosavuta kuyeretsa chipinda chowotcherera.Pamene makina otsekemera a reflow amafunika kutsukidwa ndi kusungidwa, kapena mbale ikagwa panthawi yopanga, chivundikiro chapamwamba cha ng'anjo yowonongeka chiyenera kutsegulidwa.

9. Reflow soldering kutulutsa chipangizo: kukakamiza kutulutsa kumatha kuonetsetsa kuti kutulutsa kwabwino, kusefera kwapadera kwa mpweya, kuonetsetsa kuti mpweya umakhala wabwino m'malo ogwirira ntchito, kuchepetsa kuipitsidwa kwa gasi ku chitoliro chotulutsa.

10. Mawonekedwe a mawonekedwe a reflow soldering: kuphatikizapo mawonekedwe, gawo la kutentha ndi kutentha kwa zipangizo.
