1. Amanyathelo okusebenza kweumatshini wokuthambisa wamaza.
1).Izixhobo zokuthambisa zamazaukulungiswa phambi kwe-welding
Khangela ukuba i-PCB eza kuthengiswa ifumile, ingaba amalungu e-solder afakwe i-oxidized, akhubazekile, njl.i-flux idityaniswe kwi-nozzle interface yesitshizi.
2).Ukuqaliswa kwezixhobo zokubethelela amaza
Lungisa ububanzi bebhanti ye-soldering machine drive (okanye i-fixture) ngokobubanzi bebhodi yesekethe eprintiweyo;vula amandla kunye nomsebenzi wefeni nganye yomatshini wokuthengisela amaza.
3).Cwangcisa iiparitha ze-welding zesixhobo se-wave soldering
I-Flux Flow: Kuxhomekeke kwindlela i-flux iqhagamshelana ngayo emazantsi e-PCB.Umjikelo uyafuneka ukuba uqatywe ngokulinganayo emazantsi ePCB.Ukuqala ukusuka kumngxuma ophumela kwi-PCB, kufuneka kubekho isixa esincinci sokuqukuqela kumphezulu womngxuma ophumela kumngxunya ophumela kwipad, kodwa ungangeni.
Ubushushu bokufudumala: Iseti ngokweyona meko ye-oven microwave preheating zone (ubushushu bokwenyani kumphezulu wePCB ngokuqhelekileyo bungama-90-130°C, iqondo lobushushu lepleyiti eshinyeneyo ngumda ophezulu webhodi edityanisiweyo kunye nokunye okuninzi. Amacandelo e-SMD, kunye ne-slope yokunyuka kweqondo lokushisa ngaphantsi okanye ilingana ne-2 ° C / S;
Isantya ibhanti Conveyor: ngokutsho oomatshini amaza ezahlukeneyo soldering kunye nezicwangciso PCB ukuba solder (ngokubanzi 0.8-1.60m / min);ubushushu be-solder: (kufuneka ibe yinyani yokushisa ephezulu eboniswe kwisixhobo (SN-Ag-Cu 260±5℃, SN-Cu 265±5 °C). okanye i-LCD imalunga ne-3 ° C ngaphezulu kweqondo lobushushu lokwenene;
Umlinganiselo wobude bencopho: xa idlula ezantsi kwePCB, lungelelanisa ukuya kwi-1/2 ~ 2/3 yobukhulu bePCB;
I-angle ye-welding: ukuthambekela kokudluliselwa: 4.5-5.5 °;ixesha welding: ngokubanzi 3-4 imizuzwana.
4).Imveliso kufuneka ithengiswe kwaye ihlolwe (emva kokuba zonke iiparamitha ze-welding zifikelele kwixabiso elimiselweyo)
Beka ngobunono ibhodi yesekethe eprintiweyo kwibhanti yokuhambisa (okanye i-fixture), umatshini utshiza ngokuzenzekelayo i-rib flux, i-preheats, i-solders wave kunye nokupholisa;ibhodi yesiphaluka eprintiweyo idibaniswe ekuphumeni kwe-soldering wave;ngokomgangatho wokuhlolwa kwefektri.
5).Lungisa iiparamitha zokuwelda ngokweziphumo ze-welding PCB
6).Yenza imveliso ye-welding eqhubekayo, qhagamshela ibhodi yesekethe eprintiweyo kwindawo yokukhupha i-soldering wave, uyibeke kwibhokisi ye-anti-static turnover emva kokuhlolwa, kwaye uthumele ibhodi yokugcinwa kwenkqubo elandelayo;ngexesha lenkqubo ye-welding eqhubekayo, ibhodi nganye eprintiweyo kufuneka ihlolwe, kwaye iziphene ze-welding Iibhodi eziprintiweyo ezibukhali kufuneka ziphinde zithengiswa ngokukhawuleza.Ukuba kusekho iziphene emva kwe-welding, isizathu kufuneka sifumaneke, kwaye i-welding kufuneka iqhutyelwe emva kokulungelelanisa iiparitha zenkqubo.
2. Amanqaku okuqwalaselwa kwi-wave soldering operation.
1).Ngaphambi kokuthengiswa kwamaza, jonga imeko yokusebenza kwesixhobo, umgangatho webhodi yesekethe eprintiweyo ukuba ithengiswe kunye nobume beplagi.
2).Kwinkqubo yokuthengiswa kwamaza, kufuneka uhlale unikela ingqalelo ekusebenzeni kwezixhobo, ucoce i-oxides kumphezulu webhafu ye-tin ngexesha, yongeza i-polyphenylene ether okanye ioyile yesesame kunye nezinye i-antioxidants, kwaye uzalise i-solder ngexesha.
3).Emva kwe-wave soldering, umgangatho we-welding kufuneka uhlolwe ibhloko ngebhloko.Kwinani elincinci lezinto ezilahlekileyo ze-soldering kunye ne-bridging soldering points, ukulungiswa kwe-welding manual kufuneka kuqhutywe ngexesha.Ukuba kukho inani elikhulu leengxaki zomgangatho we-welding, fumana izizathu ngexesha.
I-Wave soldering bubuchule obuqolileyo bokuthengisa kwimizi-mveliso.Nangona kunjalo, ngenani elikhulu lezicelo zezixhobo zokunyuka komphezulu, inkqubo yokuhlanganisa i-plug-in yamacandelo kunye nezixhobo zokunyuka komhlaba ezihlanganiswe kwibhodi yesekethe ngaxeshanye ibe yindlela eqhelekileyo yokuhlanganisa kwiimveliso ze-elektroniki, ngaloo ndlela ibonelela ngeeparitha zenkqubo. kwitekhnoloji yokuthengisa amaza.Ukuze kuhlangatyezwane neemfuno ezingqongqo, abantu basaphonononga rhoqo iindlela zokuphucula umgangatho we-soldering of soldering wave, kuquka: ukuqinisa ulawulo lomgangatho woyilo lwebhodi yesekethe eprintiweyo kunye namacandelo phambi kokubambisa;ukuphucula izixhobo zenkqubo ezifana ne-flux kunye ne-solder Ulawulo lomgangatho;ngexesha lenkqubo welding, nokwandisa inkqubo parameters ezifana preheating lobushushu, ukuthambekela track welding, ukuphakama amaza, ubushushu welding njalo njalo.
