Ukufunyanwa kwe-Welding engalunganga ye-BGA kunye neengxaki ze-Welding kwakhona

Ukuba jikeleleUmatshini weX-reyiIngxaki ye-welding yenyani ayinakujongwa, ungasebenzisa i-inki ebomvu kunye necandelo lokufumana ingxaki?Kodwa ukuba ukufudumeza okanyereflow ovenwelding, PCBA processing emva kovavanyo kwaye waphumelela, ke wenze inki ebomvu kunye novavanyo isilayi iya kuba luncedo?Ukuba umthengi ucela ukuba athathe ibhodi elungileyo ukuba ayenze kwakhona, ngaba sinokubona ukuba yingxaki yenkqubo?

I-Q1: Ngokuqhelekileyo, ukuba i-welding yobuxoki yamacandelo angenayo i-BGA inokubonwa ngeso lenyama, kuba i-solder ye-welding yobuxoki iya kwenza i-welding defect ecacileyo, enokuthi ibonwe ngokulula phantsi kwemeko yesiqhelo ye-solder.

Ukusuka kwinkcazo yombuzo, sinokuqikelela ukuba umntu obuza umbuzo kufuneka adibane nomgangatho ongaqhelekanga we-BGA okanye we-IC welding yecandelo.I-3DX-Ray scanning imaging ingasetyenziselwa ukukhangela i-welding yobuxoki kwi-SMT SMT processing.Esi sesona sixhobo sisebenzayo kunye nendlela yokuhlolwa kwe-welding yamacandelo e-BGA/IC, eqinisekiswa ngokungathandabuzekiyo luninzi lwabavelisi bePCBA.

Kodwa ukuba ibhola ngokwayo yaphukile okanye umgangatho webhola awuqhelekanga, kusenokufuneka ukuba ihlalutywe kusetyenziswa i-inki ebomvu kunye novavanyo lwesilayi, kuba le ngxaki ayibonwa ngeX-reyi.

I-Q2: Ukuba ingxaki ye-BGA ayiqinisekiswanga, i-solder paste yi-reflow welding ye-oven kwakhona, enokuthi igubungele eyona ngxaki.Ukongezelela, enye ingxaki kukuba umthombo wamanqaku asemgangathweni uya kutshatyalaliswa, ngoko akuqinisekiswanga ukuba sinokujonga amanqaku amabi okwenene.

Ukungaphumeleli kwe-BGA kufuneka kuqala kuphelise iingxaki zomgangatho webhola yetoti ngokwayo, kwaye abanye kufuneka baqinisekiswe njengeengxaki ze-welding interface okanye uhlengahlengiso lobushushu.Amakhonkco ahlukeneyo aya kuvelisa amanqaku angaqhelekanga ahlukeneyo.Kwaye uninzi lwe-welding ye-BGA embi ayiyongxaki yenkqubo.
Ukuba ngenene sifuna ukuhlalutya, kuyacetyiswa ukuba kuthathwe isiqwenga seemveliso ezineziphene ukuze kuchongwe yonke indawo, siqinisekise ngomgangatho odidayo wekhonkco ngalinye, ukubonisa ukuba siyadibana na nolu hlobo lwesiphene, size sisombulule ngokufanelekileyo.

I-Zhejiang NeoDen Technology Co., LTD., Yasekwa ngo-2010, ngumvelisi oqeqeshiweyo okhethekileyo kwi-SMT pick and place machine, i-oven reflow, umatshini wokushicilela we-stencil, umgca wemveliso we-SMT kunye nezinye iiMveliso ze-SMT.Izakhono kunye nenkxaso yesiNgesi yobuchwephesha kunye neenjineli zenkonzo, ukuqinisekisa impendulo ekhawulezileyo kwiiyure ezisi-8, isisombululo sibonelela ngeeyure ezingama-24.Eyodwa phakathi kwabo bonke abavelisi baseTshayina ababhalise kwaye bavunywa i-CE yiTUV NORD.
