Mitundu ya uvuni wa reflow I

Gulu molingana ndiukadaulo

1. Ovuni yotulutsa mpweya wotentha
Ovuni ya Reflow imachitika motere pogwiritsa ntchito ma heater ndi mafani kuti azitenthetsa kutentha kwamkati mosalekeza kenako ndikuzungulira.Mtundu uwu wa kuwotcherera reflow umadziwika ndi kutuluka kwa laminar kwa mpweya wotentha kusamutsa kutentha kofunikira pakuwotcherera.Ubwino wake ndi wakuti mphamvu ya kutentha nthawi zonse imasungidwa mumtundu wina wa kutentha pamene kuwotcherera, sipadzakhala kutentha kwadzidzidzi ndi kuzizira, kotero kuti kuwotcherera kumakhala kosavuta, kupambana kumakhala kopambana.

2. Kuwotcherera kwa gasi wotentha
Kuwotcherera kwa gasi wotentha kumadziwika ndi kugwiritsa ntchito kuwotcherera kwa gasi wotentha.Njira yowotcherera imafunikira kusintha kosalekeza kwa mfundo zowotcherera molingana ndi makulidwe osiyanasiyana, zomwe zimachepetsa kwambiri kuwotcherera.

3. Hot waya reflow kuwotcherera
Chitsulo chotenthetsera chimagwiritsidwa ntchito kuwotcherera mwachindunji, chomwe nthawi zambiri chimagwiritsidwa ntchito mu chingwe, ndipo zolumikizira zake zimakhala ndi kusinthasintha kwina.Choncho, kuwotcherera ikuchitika ndi Kutentha popanda solder phala, chifukwa ndi zovuta kuwotcherera luso, kotero kuwotcherera liwiro ndi pang'onopang'ono, amene m'mbuyo ntchito dzuwa.

4. Kuwotcherera reflow induction
Pogwiritsa ntchito mfundo ya inductive eddy current, mankhwalawa safunikira kulumikizana ndi makina, motero amachepetsa chonyamulira, motero amawongolera kwambiri kutentha.Komabe, chifukwa cha kusowa kwa chonyamulira, zimakhala zovuta kulamulira kutentha, ndipo n'zosavuta kulakwitsa ngati teknoloji palibe kunyumba.

5. kuwotcherera laser reflow
Reflow kuwotcherera ndi Kutentha kwa laser, chifukwa laser ali ndi lolunjika bwino ndi mwachindunji, kugwiritsa ntchito kuwotcherera laser kungakhale wabwino kuwotcherera mfundo processing, kuti kuwotcherera mankhwala akhoza bwino ankalamulira kuchepetsa kupatuka.

6. IR reflow kuwotcherera ng'anjo
Mtundu uwu wa reflow kuwotcherera ng'anjo ndi makamaka conveyor lamba mtundu, koma conveyor lamba yekha amasewera gawo lothandizira, kutengerapo gawo lapansi, Kutentha mode ake makamaka zochokera infuraredi kutentha gwero kutentha mu njira cheza, kutentha mu ng'anjo ndi zambiri. yunifolomu kuposa njira yapitayi, mauna ndi okulirapo, oyenera kusonkhana mbali ziwiri za gawo lapansi lotenthetsera kuwotcherera.Mtundu uwu wa ng'anjo ya reflow ukhoza kunenedwa kuti ndi mtundu woyambirira wa ng'anjo yotsitsimula.Amagwiritsidwa ntchito kwambiri ku China, ndipo mtengo wake ndi wotsika mtengo.

7. Gasi gawo reflow kuwotcherera
Gasi gawo reflux kuwotcherera amatchedwanso VaporPhaseSoldering (VPS), koma amatchedwanso condensationsolding.Malo osungunuka ndi pafupifupi 215 ℃.Nthunzi imapangidwa ndi kuwira.Pali mapaipi okometsera pamwamba ndi kuzungulira ng'anjoyo kuti achepetse nthunzi mung'anjoyo.America poyamba ntchito kuwotcherera wa wandiweyani filimu Integrated dera (IC), mpweya zobisika kutentha kumasulidwa parker si tcheru dongosolo thupi ndi mawonekedwe a SMA, akhoza kupanga zigawo zikuluzikulu wogawana Kutentha kwa kuwotcherera kutentha, kuwotcherera kutentha kusunga, popanda njira kutentha kulamulira ntchito kukwaniritsa zosowa zosiyanasiyana kutentha kuwotcherera, VPS gasi gawo ndi zimalimbikitsa nthunzi ndi otsika mpweya okhutira, matenthedwe kutembenuka mlingo ndi mkulu, koma kukwera mtengo kwa zosungunulira, ndi mmene ozoni kutha zinthu, kotero ntchito pa malire a mayiko masiku ano zofunika kuti asagwiritsenso ntchito njira imeneyi kuwononga chilengedwe.

NeoDen imapereka mayankho athunthu a mzere wa SMT, kuphatikiza uvuni wa SMT reflow, makina osokera, makina osankha ndi malo, makina osindikizira a solder, PCB loader, PCB unloader, chip mounter, SMT AOI makina, makina a SMT SPI, makina a SMT X-Ray, Zida zopangira msonkhano wa SMT, Zida zopangira PCB SMT zida zosinthira, ndi zina zilizonse makina a SMT omwe mungafune, chonde titumizireni kuti mumve zambiri:
