Izinga lokushisa elingenawo umthofu le-reflow soldering liphezulu kakhulu kunezinga lokushisa elisekelwe kumthofu le-reflow soldering.Ukusethwa kwezinga lokushisa kwe-solder-free reflow soldering nakho kunzima ukulungisa.Ikakhulukazi ngenxa yokuthi iwindi lenqubo yokugeleza kabusha kwe-lead-free soldering lincane kakhulu, ukulawulwa komehluko wezinga lokushisa eliseceleni kubaluleke kakhulu.Umehluko omkhulu wezinga lokushisa elingemuva ekufakweni kwe-reflow soldering uzodala ukukhubazeka kweqoqo.Ngakho-ke singawunciphisa kanjani umehluko wezinga lokushisa elingemuva ekufakweni kwe-reflow soldering ukuze sifinyelele umphumela wokudambisa ogeleza kabusha ongenamthofu?I-Chengyuan Automation iqala ezintweni ezine ezithinta umthelela we-reflow soldering.
1. Ukudluliswa komoya oshisayo esithandweni sokushisa sokugeleza esingenamthofu
Njengamanje, i-lead-free reflow soldering evamile isebenzisa indlela yokushisa komoya oshisayo.Enqubweni yokuthuthukiswa kwe-oven soldering ye-reflow, ukufudumeza kwe-infrared nakho kuvele.Kodwa-ke, ngenxa yokushisisa kwe-infrared, ukumuncwa kwe-infrared kanye nokubukeka kwezakhi zemibala ehlukene kuhlukile futhi ngenxa yokwangempela okuseduze Idivayisi ivinjiwe futhi ikhiqize umphumela wethunzi, futhi zombili izimo zizodala umehluko wokushisa futhi zibeka i-lead soldering engozini yokugxumela ngaphandle. yewindi lenqubo.Ngakho-ke, ubuchwepheshe bokushisa kwe-infrared buye baqedwa kancane kancane endleleni yokushisa yama-oven soldering ovens.Ekufakweni kwe-lead-free soldering, kuyadingeka ukunaka umphumela wokudlulisa ukushisa, ikakhulukazi kumadivayisi wangempela anamandla amakhulu okushisa.Uma ukudluliswa kokushisa okwanele kungatholakali, izinga lokushisa elikhuphukayo lizosalela kakhulu ngemuva kwamadivayisi anomthamo omncane wokushisa, okuholela ekuhlukeni kwezinga lokushisa elingemuva.Uma kuqhathaniswa nokusebenzisa ihhavini lokugeleza kabusha elingenawo umthofu ogcwele womoya oshisayo, umehluko wezinga lokushisa ongemuva we-solder-free reflow soldering uzoncishiswa.
2. Ukulawulwa kwesivinini se-chain ye-ovini yokugeleza kabusha engenamthofu
Isilawuli sesivinini seketango le-reflow soldering engenamthofu kuzothinta umehluko wokushisa osemaceleni webhodi lesekethe.Ngokuvamile, ukwehlisa isivinini seketango kuzonikeza amadivayisi anamandla amakhulu okushisa isikhathi esengeziwe sokufudumeza, ngaleyo ndlela kunciphise umehluko wokushisa osemaceleni.Kodwa emva kwakho konke, ukulungiselelwa kwejika lokushisa kwesithando somlilo kuncike ezidingweni ze-solder paste, ngakho-ke ukunciphisa isivinini seketanga elilinganiselwe akunangqondo ekukhiqizeni kwangempela.Lokhu kuncike ekusetshenzisweni kwe-solder paste.Uma kunezingxenye eziningi ezinkulu ezimunca ukushisa ebhodini lesekethe, Ngezingxenye, kutuswa ukwehlisa isivinini seketanga lokuhamba kabusha ukuze izingxenye ezinkulu ze-chip zikwazi ukumunca ngokuphelele ukushisa.
3. Ukulawulwa kwesivinini somoya kanye nevolumu yomoya kuhhavini yokugeleza kabusha engenamthofu
Uma ugcina ezinye izimo kuhhavini ogeleza kabusha ongenawo umthofu zingashintshiwe futhi unciphisa kuphela isivinini sefeni kuhhavini ogelezayo ongenawo umthofu ngo-30%, izinga lokushisa ebhodini lesifunda lizokwehla cishe ngama-degree angu-10.Kuyabonakala ukuthi ukulawulwa kwesivinini somoya kanye nevolumu yomoya kubalulekile ekushiseni ukulawulwa kwezinga lokushisa.Ukuze ulawule isivinini somoya kanye nevolumu yomoya, amaphuzu amabili adinga ukunakwa, anganciphisa umehluko wokushisa ongasemuva esithandweni sokugeleza esingenamthofu futhi kuthuthukiswe umphumela wokudambisa:
⑴Isivinini sefeni kufanele silawulwe ukuguqulwa kwemvamisa ukuze kuncishiswe umthelela wokushintshashintsha kwamandla kagesi kuyo;
⑵ Yehlisa umthamo womoya okhiphayo wezinto zokusebenza ngangokunokwenzeka, ngoba umthwalo omaphakathi womoya okhipha umoya ngokuvamile awuzinzi futhi ungathinta kalula ukugeleza komoya oshisayo esithandweni.
4. I-solder ye-reflow soldering inokuzinza okuhle futhi inganciphisa umehluko wokushisa esithandweni.
Ngisho noma sithola ukulungiselelwa kwephrofayili yephrofayili yezinga lokushisa le-ovini eligeleza kabusha eligcwele umthofu, ukulifinyelela kusadinga ukuzinza, ukuphindaphinda kanye nokuvumelana kokudayiswa okugeleza kabusha okunganomthofu ukuze uqinisekise lokho.Ikakhulukazi ekukhiqizeni umthofu, uma kukhona ukukhukhuleka okuncane ngenxa yezizathu zemishini, kulula ukuphuma efasiteleni lenqubo futhi kubangele i-soldering ebandayo noma umonakalo wangempela wedivayisi.Ngakho-ke, abakhiqizi abaningi ngokwengeziwe sebeqala ukudinga ukuhlolwa kokuzinza kwemishini.
