Umatshini wokuthambisa wamaza okhethiweyoinika indlela entsha yokuwelda, enenzuzo engenakuthelekiswa nanto ngaphezu kwe-welding manual, yendabukoumatshini wokuthambisa wamazakunye nomngxumareflow oven.Nangona kunjalo, akukho ndlela ye-welding inokugqibelela, kwaye i-wave soldering ekhethiweyo ikwanayo "imida" egqitywe ziimpawu zezixhobo.
1. Umbhobho okhethiweyo we-wave soldering unokuya phezulu nasezantsi kuphela, amacala ekhohlo nasekunene, akukho kuqonda kokujikeleza kwe-3 d, i-wave soldering i-crest ekhethiweyo ithe nkqo, ingeyiyo i-wave ethe tye (i-lateral wave), ngoko ke ngokufanayo kufakelwe kwisihlanganisi sombane. kudonga lwe-microwave, isigqubuthelo kunye nokufakwa ngokuthe nkqo kumalungu ebhodi yebhodi kwibhodi yesekethe eprintiweyo kunzima ukuphumeza ukuwelda, Kwindibano ye-rf yesiqhagamshelo kunye nendibano yentambo ye-multi-core ayikwazi ukuphunyezwa ukuwelda, ngokuqinisekileyo, ukuwelda kwamaza emveli kunye nokuwelda kwakhona. ayinakwenziwa;Nangona kunye ne-robot welding, kukho "imida" ethile.
2. Umda wesibini we-selective wave soldering isivuno.Ukuthengiswa kwamaza emveli yibhodi yesekethe yonke ngexesha elinye, ukhetho lwe-welding kukuwelda okanye ukuwelda okuncinci kombhobho, kodwa ngophuhliso olukhawulezayo lweshishini lombane, ngokusebenzisa amacandelo umngxuma ngaphantsi nangaphantsi, imveliso ngoyilo lokumodareyitha lokukhetha i-wave soldering, i-multi-cylinder parallel iphuculwe, ngakumbi iteknoloji yaseJamani entsha, umthamo wemveliso ube liqhezu.
3. I-ADAPTS ye-wave soldering ekhethiweyo ukuya kwisithuba se-pin (umgama osembindini).Kwindibano yoxinaniso oluphezulu lwe-PCBA, isithuba seziqhagamshelo zombane kunye neesekethe ezidityanisiweyo ze-double-in-line (DIP) iya isiba ncinci kwaye incinci, isithuba seziqhagamshelo zombane kunye nezikhonkwane ezidityanisiweyo ze-DIP (umgama ophakathi) iye yancitshiswa ukusuka kwi-1.27mm eqhelekileyo ukuya kwi-0.5mm okanye ngaphantsi;Oku kuzisa imiceli mngeni ekuthengiseni amaza emveli kunye nokukhethwa kwe-wave soldering.Xa isithuba sesikhonkwane sesiqhagamshelanisi sombane singaphantsi kwe-1.0mm okanye ukuya kutsho kwi-0.5mm, i-point-by-point welding iya kuthintelwa ngobukhulu bombhobho we-crest, kwaye i-welding yokutsala iya kwandisa isiphene se-welding spot bridging.Ke ngoko, ukungalungi kwe-solder ekhethiweyo kugxininiswa kwindibano yoxinaniso oluphezulu.
4. Xa kuthelekiswa ne-solder wave yemveli, umgama we-welding wezixhobo zokuwelda ezikhethiweyo unokuba mncinci kunezo zemveli ze-solder ngenxa yomsebenzi okhethekileyo we-solder joints "ezincinci".Ukuwelda okuthembekileyo kunokufezekiswa kumacandelo angaphakathi komngxuma kunye nomgama wephini elikhulu kuno okanye elilingana ne-2mm;Kumacandelo angaphakathi komngxuma kunye nomgama we-pin we-1 ~ 2mm, indawo ye-welding "encinci" umsebenzi wesixhobo kufuneka isetyenziswe ukufezekisa i-welding ethembekileyo;Kwimibhobho yomngxuma kunye nomgama we-pin ngaphantsi kwe-1mm, kuyimfuneko ukuyila i-nozzle ekhethekileyo kwaye yamkele inkqubo ekhethekileyo yokufezekisa i-welding engenasiphako.
5. Ukuba umgama ophakathi kwesiqhagamshelo sombane ungaphantsi okanye ulingana no-0.5mm, sebenzisa iteknoloji yoqhagamshelwano oluphezulu lwekhebula.
I-selective wave soldering ineemfuno ezingqongqo kuyilo lwePCB kunye netekhnoloji, kodwa kusekho iziphene zokuwelda, ezinje ngamaso enkcenkce, awona anzima kakhulu ukusombulula.
6. Isixhobo siyabiza, isixhobo sokuthengisa amaza sodidi esisezantsi sixabisa malunga ne-200,000 yeedola, kwaye ukusebenza kakuhle kwe-selective wave soldering kuphantsi.Okwangoku, eyona nto iphambili yokukhetha i-wave soldering ifuna umjikelo we-5s, kwaye kwi-PCB enamalungu amaninzi okuphuma emngxunyeni, ayinakukwazi ukuqhubeka nokubetha kwemveliso kwimveliso yobuninzi, kwaye ixabiso likhulu.
