Wave soldering nkqu tin izizathu kunye neendlela zonyango

Umatshini we-wave solderingnkqu netoti yingxaki eqhelekileyo kwimveliso yeemveliso zombane iplagi-in wave soldering, ikakhulu ngenxa amaza soldering nkqu netoti okubangelwa izizathu ezahlukeneyo.Ukuba ufuna ukulungelelanisa i-soldering ye-wave ukuze unciphise i-tin, kuya kufuneka ufumanise izizathu zokubethelwa kwamaza kunye ne-tin.Apha ukwabelana ngoonobangela kunye nemibono yokucubungula.

I-Wave soldering enezizathu zetoti.

1. Ubushushu be-Flux preheating buphezulu kakhulu okanye buphantsi kakhulu, ngokubanzi kwi-100 ~ 110 degrees, ukufudumeza kuphantsi kakhulu, umsebenzi we-flux awuphezulu.Ukushisa okuphezulu kakhulu, kwi-tin steel flux iphelile, kodwa kulula nokuba i-tin.
2. Akukho flux okanye i-flux ayanelanga okanye ayilingani, ukuxinezeleka komphezulu we-tin etyhidiweyo ayikhutshwa, okukhokelela ekubeni kube lula ukuyifaka.
3. Jonga ubushushu beziko letin, ulawulo malunga nama-265 degrees, kungcono ukusebenzisa ithemometha ukulinganisa ubushushu be-wave crest xa i-wave wave ibetha, kuba isivamvo sobushushu sesixhobo sinokuba sisezantsi kwiziko. okanye ezinye iindawo.Preheating lobushushu akwanelanga kuya kukhokelela amacandelo ayikwazi ukufikelela iqondo lobushushu, inkqubo welding ngenxa yecandelo ukufunxa ubushushu, nto leyo ephumela inkonkxa utsalo amahlwempu, kunye nokwakheka nkqu inkonkxa.Kusenokubakho ubushushu obuphantsi beziko letoti, okanye isantya sokuwelda sikhawuleza kakhulu.
4. Ukuhlolwa rhoqo ukwenza uhlalutyo lokubunjwa kwe-tin, kunokwenzeka ukuba ubhedu okanye omnye umxholo wesinyithi ugqithise umgangatho, okubangela ukunciphisa ukuhamba kwe-tin, okubangelwa lula nokuba yi-tin.
5. Jonga i-engile yengoma ye-soldering, i-7 degrees iyona nto ingcono, ilula kakhulu ukuxhoma i-tin.
6. I-IC kunye nomqolo woyilo olubi, zidityaniswe, amacala amane IC isithuba seenyawo ezishinyeneyo <0.4mm, akukho angle yokuthambeka ebhodini.
7. PCB eshushu embindini deformation deformation okubangelwa nkqu netoti.
8. Intsimbi yenkcenkce iphezulu kakhulu, eyokuqala itya inkonkxa kakhulu, ityebe kakhulu, kufuneka ilingane.
9. Iipadi zebhodi yesiphaluka aziyilwanga phakathi kwedama le-solder, edibeneyo emva kokushicilela kwi-solder paste;okanye ibhodi yesekethe ngokwayo yenzelwe ukuba idama solder / ibhulorho, kodwa kwimveliso egqityiweyo ibe yinxalenye okanye zonke off, ke kwakhona kulula nokuba toti.

Wave soldering nkqu iindlela zonyango inkonkxa.

1. I-Flux ayanele okanye ayanele, yandisa ukuhamba.
2. I-tin edibeneyo ukukhawulezisa inqaku lesantya, indawo yokwandisa i-engile yomzila.
3. Musa ukusebenzisa i-1 wave, kunye namaza ama-2 e-wave enye, udle ukuphakama kwe-tin akufuneki kube yi-1/2, unokuchukumisa nje emazantsi ebhodi ngokwaneleyo.Ukuba unetreyi, ngoko ke umphezulu wenkcenkce okwitreyi ogxunyekwe ngaphandle kowona mphezulu uphezulu ulungile.
4. Nokuba ibhodi ikhubazekile.
5. Ukuba i-2 wave single hit ayilunganga, kunye ne-1 wave punch, i-2 wave ibetha ezantsi chukumisa izikhonkwane ezikuyo, ukuze ukwazi ukulungisa imilo yejoyinti ye-solder, ngaphandle kokulungileyo.
