Yintoni Umahluko phakathi kweLaser Welding kunye neReflow Welding?

Intshayelelo kureflow oven

Hlaziya i-oveniisebenzisa ukutyabeka okuguquguqukayo, emva koko ifudumeza ibhodi yesekethe/i-flux esebenzayo, emva koko isebenzisa umbhobho wokuwelda kwimowudi yokuwelda.I-welding yentsimbi ye-artificial yokufakelwa idinga ukusebenzisa i-point-to-point welding kwindawo nganye yebhodi yesiphaluka, ngoko ke kukho abaqhubi be-welding.Umatshini wokuthambisa wamaza okhethiweyoyindlela yokuvelisa ibhetshi yemveliso yomgca wokuhlanganisa, ubungakanani obahlukeneyo bombhobho wokuwelda bunokuba yibhetshi yokuwelda, ngokuqhelekileyo ukusebenza kakuhle kwe-welding kunokuphuculwa kaninzi ngaphezu kwe-welding manual (kuxhomekeke kuyilo lwebhodi yesekethe ethile).Ngenxa yokusetyenziswa programmable mobile cylinder tin encinci kunye neentlobo ngeentlobo welding umbhobho bhetyebhetye, (tin cylinder umthamo malunga 11 kg), ngoko ukuwelda zinokusetwa ngenkqubo ukuphepha ibhodi yesekethe phantsi kwezinye izikrufu ezisisigxina kunye nokomelezwa kunye nezinye. iinxalenye, ukuze ungaqhagamshelani ne-solder ephezulu yokushisa kwaye ubangele umonakalo.Le ndlela ye-welding, ngaphandle kokusetyenziswa kwe-tray ye-welding yesiko kunye nezinye iindlela, ifanelekile kakhulu kwiindidi ezininzi, imodi yokuvelisa ibhetshi encinci.

 

I-Reflow welding ineenzuzo ezilandelayo:

Ukusebenza kwemveliso ephezulu kwi-welding, inokuqonda iqondo eliphezulu lokuwelda okuzenzekelayo.

Ulawulo oluchanekileyo lokuma kwenaliti ye-flux kunye nobungakanani benaliti, ukuphakama kwencopho ye-microwave kunye nesikhundla se-welding.

Ukukhuselwa kwe-nitrojeni kumphezulu we-microwave peak;Ukuphuculwa kweeparameters zenkqubo kwijoyinti ngalinye le-solder.

Ukutshintshwa ngokukhawuleza kwemibhobho yobukhulu obuhlukeneyo.

Ukuwelda indawo enye kunye nomngxuma isidibanisi pin ngokulandelelana ukuwelda ubuchwepheshe ezidityanisiweyo.

Ngokweemfuno kunokusetwa solder imilo joint "amanqatha" "obhityileyo" isidanga.

Unokukhetha iimodyuli ezahlukeneyo zokufudumeza (i-infrared, umoya oshushu) kunye nemodyuli yokufudumala eyongezelelweyo ngaphezu kwebhodi.

Ukugcinwa kwempompo ye-electromagnetic simahla.

Ukukhethwa kwezinto zokwakha kulungele ngokupheleleyo ukusetyenziswa kwe-solder-free solder.

Uyilo lwemodyuli lunciphisa ixesha lokulondoloza.

 

Intshayelelo kwi welding laser

Umthombo wokukhanya we-laser welding eluhlaza yi-laser light-emitting diode (LLED), enokuthi igxininise ngokuchanekileyo kwi-solder joint ngokusebenzisa inkqubo ye-optical.Inzuzo ye-laser welding kukuba inokulawula ngokuchanekileyo kunye nokwandisa amandla afunekayo ekudibaniseni.Ilungele inkqubo ye-welding ekhethiweyo okanye ukusebenzisa i-tin wire connector.Kumacandelo e-SMD, i-solder paste kufuneka isetyenziswe kuqala kwaye emva koko i-welded.Inkqubo ye-welding ihlukaniswe ngamanyathelo amabini: okokuqala i-solder paste ishushu, kwaye i-solder joint is preheated.Emva koko, i-solder paste esetyenziselwa i-welding iyancibilika ngokupheleleyo, kwaye i-solder imanziswe ngokupheleleyo kwi-pad ukwenza i-weld.Sebenzisa i-laser generator kunye ne-optical focusing component welding, ubuninzi bamandla, ukuhanjiswa kobushushu obuphezulu, i-welding engaxhunywanga, i-solder. ingaba yintlama ye-solder okanye i-tin wire, ilungele ngokukodwa ukuwelda indawo encinci ye-solder okanye i-solder spot power encinci incinci, yonga amandla.

 

Iimpawu ze-laser welding

Ulawulo lwekhadi lebhodi ye-multi-axis servo motor, ukuchaneka kokubeka okuphezulu.

Indawo encinci yelaser, kubungakanani obuncinci beepads, izixhobo zokubeka izithuba zineenzuzo ezicacileyo zokuwelda.

I-welding engaqhagamshelani nayo, akukho xinzelelo lomatshini, umngcipheko ongatshintshiyo.

Wuxi slag, ukunciphisa inkunkuma flux, ixabiso eliphantsi imveliso.

Iimveliso zeWeldable zizityebi ngohlobo.

Ukukhetha i-solder.

 

Izinto eziluncedo zokuwelda laser

Kwi-substrate ye-elektroniki ye-ultra-fine, i-multi-layer electronic components, "i-teknoloji yendabuko" ayikwazanga ukusebenzisa, nto leyo eyabangela inkqubela phambili ekhawulezayo yeteknoloji.Ukucutshungulwa kwamalungu amancinci amancinci angafanelanga indlela yentsimbi ye-solder yendabuko ekugqibeleni igqitywe nge-laser welding.I-non-contact welding yeyona nzuzo inkulu ye-laser welding.Akukho mfuneko yokuchukumisa i-substrate kunye namacandelo e-elektroniki nonke, kwaye ukubonelela nge-solder kuphela nge-laser irradiation ayifaki umthwalo womzimba.Ukufudumeza okusebenzayo kunye ne-blue laser beam nakho kuyinzuzo, engasetyenziselwa ukukhanyisa iindawo ezinqamlekileyo apho intloko ye-soldering ayikwazi ukungena kunye nee-angles ezahlukeneyo xa kungekho mgama phakathi kwamacandelo asondeleyo kwindibano exineneyo.Intloko yentsimbi ye-solder idinga ukutshintshwa rhoqo, ngelixa iindawo ezisecaleni ze-laser welding kufuneka zitshintshwe zimbalwa kakhulu kwaye iindleko zokugcinwa ziphantsi.
