Kunama-motor amaningana wokugcwalisa kabusha i-solder, iyini imisebenzi yawo?Zingaki izindawo zokushisa ezikhona, futhi liyini izinga lokushisa?

Kuyini i-reflow soldering?

I-Reflow soldering ibhekisela ekusetshenzisweni kwe-solder paste ukuxhuma ingxenye ye-elekthronikhi eyodwa noma ngaphezulu kumaphedi okuxhumana, kanye nokuncibilikisa i-solder ngokushisisa okulawulwayo ukuze kuzuzwe ukubopha okungapheli.Izindlela zokushisisa ezihlukene ezifana namahhavini agelezayo, amalambu okushisa ama-infrared, noma izibhamu zokushisa zingasetshenziswa.okokushisela.I-Reflow soldering iyindlela evame ukusetshenziswa kakhulu yokuhlanganisa izingxenye ze-elekthronikhi kumabhodi esekethe aphrintiwe ngobuchwepheshe bokukhweza komhlaba.Enye indlela iwukuxhuma izingxenye ze-elekthronikhi ngokufaka i- through-hole mounting.

Umsebenzi we-motor we-reflow soldering?

Ukushisa okusebenzayo kwe-reflow soldering kuphezulu kakhulu, futhi umsebenzi oyinhloko we-motor ukushayela isondo lomoya ukuze kukhishwe ukushisa.

Zingaki izindawo zokushisa lapho i-reflow soldering inazo?Liyini izinga lokushisa?Iyiphi indawo eyisihluthulelo?

I-Chengyuan reflow soldering ihlukaniswe ngezindawo ezine zokushisa ngokuvumelana nomsebenzi wendawo yokushisa: indawo yokushisa, indawo yokushisa engashintshi, indawo yokunamathisela, nendawo yokupholisa.

I-solder ye-reflow evamile emakethe ihlanganisa i-solder ye-temperature reflow soldering eyisishiyagalombili, i-solder ye-temperature zone reflow soldering eyisithupha, i-temperature zone reflow soldering eyishumi nambili, indawo yokushisa eyishumi nambili ye-reflow soldering, i-temperature zone reflow soldering eyishumi nane, njll. Lezi zingenziwa ngokuvumelana nezidingo zamakhasimende.Kodwa-ke, i-temperature reflow soldering eyisishiyagalombili kuphela evamile emakethe yobungcweti.Ukuze kufakwe kabusha i-solder ezindaweni zokushisa eziyisishiyagalombili, ukumiswa kwezinga lokushisa kwendawo ngayinye yokushisa kuhlobene kakhulu nokunamathisela kwe-solder kanye nomkhiqizo ozothengiswa.Umsebenzi wendawo ngayinye ubucayi kakhulu.Ngokuvamile, indawo yokuqala neyesibili isetshenziswa njengezindawo zokushisa kuqala, kanti eyesithathu neyesine yizindawo zokushisa kuqala.Indawo yokushisa ehlala njalo, i-678 njengendawo yokushisela (okubaluleke kakhulu yilezi zindawo ezintathu), izindawo eziyi-8 zingasetshenziswa futhi njengendawo eyisizayo yendawo yokupholisa, nendawo yokupholisa, lezi ziyisisekelo, kufanele kushiwo ukuthi zimbalwa. izindawo ziwukhiye , Izinga lomkhiqizo kumele lithuthukiswe, iyiphi indawo ewukhiye!

1. Indawo yokushisa

Indawo yokushisa ishisa ibe ngamadigri angu-175, futhi ubude bayo bungaba ngu-100S.Kungabonakala kulokhu ukuthi izinga lokushisa lendawo yokushisa kuqala lingatholakala (ngoba lo mtshina wamukela ukuhlolwa kwe-inthanethi, awukangeni endaweni yokushisa isikhathi eside kusukela ku-0 kuya ku-46S. , ubude besikhathi 146–46=100S, njengoba izinga lokushisa lasendlini lingu-26 degrees 175–26=149 degrees izinga lokushisa;

2. Indawo yokushisa ehlala njalo

Izinga lokushisa eliphezulu endaweni yokushisa engaguquki lizungeze ama-degree angu-200, ubude besikhathi yimizuzwana engu-80, kanti umehluko phakathi kwezinga lokushisa eliphezulu nezinga lokushisa eliphansi lingama-degree angu-25.

3. Indawo yokugeleza kabusha

Izinga lokushisa eliphakeme kakhulu endaweni yokugeleza kabusha lingama-degree angu-245, izinga lokushisa eliphansi kunawo wonke lingama-degree angu-200, futhi isikhathi sokufinyelela esiqongweni singama-35/S;ukushisisa endaweni yokugeleza kabusha
Izinga: 45 degrees/35S=1.3 degrees/S Ngokuya ngokuthi (indlela yokusetha ijika lokushisa ngendlela efanele), kungabonakala ukuthi isikhathi saleli jika lokushisa ukuze sifinyelele inani eliphakeme kakhulu side kakhulu.Sonke isikhathi sokugeleza kabusha sicishe sibe ngama-60S

4. Indawo yokupholisa

Isikhathi endaweni yokupholisa sicishe sibe ngu-100S, futhi izinga lokushisa lehla lisuka ku-245 degrees liye kuma-degree angaba ngu-45.Isivinini sokupholisa sithi: 245 degrees—45 degrees=200 degrees/100S=2 degrees/S
