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, akhubazeke, njl. 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 (elona qondo lobushushu kumphezulu wePCB lidla ngokuba yi-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 ze-welding 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 yokudibanisa edibeneyo yamacandelo eplagi-in kunye nezixhobo zokunyuka komphezulu ezihlanganiswe kwibhodi yesekethe ngexesha elifanayo libe yifom yendibano eqhelekileyo kwiimveliso zombane, 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 kokubethelwa;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.
