Ufakwa njani endaweni echanekileyo amaso esibane se-SMD kwiBhodi yesibane

Kukholelwa ukuba abahlobo abenza i-SMT ukutshintsha amaso wesibane bahlala bedibana. Isibane sethu se-SMT semi-finished isibane siya kubonakala kweso sibane esinye okanye ezibini ezingaqhelekanga ngexesha lovavanyo. Ngenxa yoyilo lwesekethe, uninzi lweebhodi zeesekethe zenzelwe kwindlela enye, kwaye isibane sesibane esingaqhelekanga siya kuchaphazela isibane emva kwesibane ngasemva. Ukusetyenziswa okuqhelekileyo kwe-bead, ngeli xesha kufuneka sitshintshe i-bead yesibane esisodwa. Kukho izinto ezimbalwa ezifakiweyo ngoku, ngokusisiseko zonke zikhona “Isitika setafile ”uhlobo. Ngenxa yokuba iinyawo azikhokelwa, ii-LED zinokusondela kwi-substrate, kwaye iimeko zokutshatyalaliswa kobushushu ziphuculwe ngokupheleleyo. Kungenxa yokuba akukho “unyawo ”Kukwazisa inkxamleko enkulu ekutshintsheni ulondolozo. Masikuthathe uqonde indlela echanekileyo nesebenzayo yokutshintsha isibane esinye. Ukwenza umsebenzi omhle wokutshintsha amaso, kufuneka uhlambe izandla zakho kuqala ukunciphisa ukuxhathisa kwesikhumba ukukhusela amaso esibane ekwenzakalweni yi-electrostatic. Kwaye ulungiselele ezi zixhobo zilandelayo kunye nezinto eziphathekayo, unokuqalisa ukwakhiwa: Umpu womoya oshushu unokukhetha eyona isetyenziswa ngokuqhelekileyo ukugcinwa. IiMondrers kunye ne-alcohol zisetyenziselwa ukunceda ukudibanisa. Ukuwela i-rosin kunye notywala kunokuchithwa. I-sinus isetyenziselwa ukulungiswa kunye neziphumo zokuqhuba izibane zesibane. Amaso isibane LED ukuba kufakwe endaweni yahlulwe ngokubanzi kulandelayo: intetho yokuqala malunga nokuxelisa amaso aqukuqelayo. Ngenxa yokuba olu hlobo lwesibane lukwakwindawo eqaqambileyo, kulula ukuyibuyisela. Okokuqala, sebenzisa i-iron yokutshisa ukutshisa i-solder joints ezimbini ukususa izibane ezimbi, kwaye usebenzise i-iron ye-solder ukuze udibanise iipads ezimbini. Emva koko faka iliso elitsha lesibane kwi-electrode yokuqala ekhayo kunye nekhabayo ukuya kweyoqobo, kwaye emva koko i-welded kancinci kwizikhonkwane. Cinezela iliso lesibane ngeminwe yakho ukuliwelda. Kufuneka kubekho inani elithile le-solder kwintloko yentsimbi ye-solder ngexesha le-welding. Xa usebenza, ungasebenzisa i-iron ye-soldering ngokukhawuleza ujike ngokujika kwiipads ezimbini ukuya kwi-welded 2 ukuya ku-3 amaxesha. Oku kubalulekile, ngaphandle koko kulula ukubangela ukuba amaso amise umoya ukuchaphazela ukutshatyalaliswa kobushushu. Ukongezelela, kungcono ukusebenzisa enye i-thermal conductivity kwi-pad yesetyhula phakathi kokunciphisa ukuchasana kwe-thermal kwi-pad yetyhula phakathi ukunciphisa ukuxhathisa kwe-thermal. Buyisela udidi lwe-5050 “Isitika setafile ”(Ikwaziwa njenge-SMD) Amaso okukhanya aya kujongeka eyingxaki. Ukusebenzisa imipu yomoya oshushu kunye nentsimbi yokuthambisa yombane phantsi, nje ukuba i-aluminium substrate ingatshatyalaliswa. Emva koko sebenzisa i-iron soldering ukususa i-welding engaphezulu kwaye ushiye kuphela umaleko omncinci. Isinyathelo esilandelayo se-welding kufuneka siqale ngasemva, kuba iipads zangaphambili zifihliwe kakhulu, kwaye umpu womoya oshushu uya kutshiswa ngokulula kunye ne-collagen yezibane zesibane. Fumana indawo amaso isibane ngasemva substrate aluminiyam, kwaye uyifudumeze ngethayile enkulu okanye umpu womoya oshushu de i-weld yangaphambili inyibilike ukuwelda amaso isibane. Kwimibhobho yesibane emikhudlwana efana ne-5730, ukongeza kumalungu amabini adityanisiweyo amele iipali ze-LED, kuya kubakho iipads ezikhethekileyo zokuphelisa ubushushu phakathi. Tshisa. Ewe kunjalo, ungasebenzisa izibane ze-aluminiyam okanye eminye imithombo ye-thermal ukutshisa i-aluminium substrates. Nangona kunjalo, ngamanye amaxesha ukonakalisa iliso isibane akunyanzelekanga ukuba kufakwe endaweni yayo. Ukuba ngaphezu kwe-5 i-parallel izibane ze-parallel inokususwa ngokuthe ngqo, iintsimbi zesibane ezimbi zingasuswa ngaphandle kokuhlaziywa; Intambo emfutshane. Kwezi ndlela zimbini zingentla, eyokuqala iya kwandisa intsimbi eseleyo yangoku, kokukhona inani leengqamaniso, elincinane, kwaye akukho mfuneko yakuqwalaselwa. Indlela yesibini ayinayo impembelelo kwiintsimbi zesibane ezisele. Kodwa enye into efanayo kukuba umphezulu wesibane uya kubonakala kumachaphaza amnyama okanye kwiindawo ezimnyama, ezichaphazela ubuhle bonke. Oku kungasentla yindlela esihlala sitshintsha ngayo amaso ezibane. Ndiyathemba ukukunceda. Yimveliso yesibane yesibane se-LED enenani lamalungelo abenzi belizwe. Iimveliso eziphambili zikhanyisa ukukhanya kwe-LED, iintsimbi zesibane se-infrared ze-LED, iintsimbi zesibane se-ultraviolet ze-LED, umbala wesibane se-LED, njl. Inkulu. Ukuba ufuna ukufunda ngakumbi malunga neentsimbi zesibane se-LED, unokubonisana nenkonzo yabathengi!
