1. 0.5mm suab QFP ncoo ntev ntev, ua rau luv luv Circuit Court.
2. PLCC qhov (socket) pads yog luv dhau, ua rau tsis muaj tseeb soldering.
3. Lub ncoo ntev ntawm IC yog ntev dhau lawm thiab tus nqi ntawm cov muab tshuaj txhuam yog loj ua rau luv luv ntawm reflow.
4. Wing chip pads yog ntev dhau los ua rau pob taws txhaws thiab pob taws tsis zoo.
5. Lub ncoo ntev ntawm cov khoom siv nti yog luv dhau, ua rau muaj teeb meem soldering xws li hloov pauv, qhib Circuit Court, thiab tsis muaj peev xwm solder.
6. Qhov ntev ntev ntawm cov ntaub qhwv cov ntaub qhwv lub ntsej muag ua rau muaj teeb meem xws li sawv ntsug, qhib Circuit Court, thiab tsawg dua tin hauv cov pob qij txha.
7. Qhov dav ntawm lub ncoo yog qhov dav heev uas ua rau muaj qhov tsis xws luag xws li kev hloov pauv, khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob.
8. Qhov dav ntawm lub ncoo yog qhov dav dhau thiab cov khoom siv pob loj tsis phim lub ncoo.
9. solder ncoo dav yog nqaim, cuam tshuam qhov loj ntawm cov molten solder raws cov khoom siv solder kawg thiab PCB pads ntawm kev sib xyaw ntawm cov hlau nto ntub dej tuaj yeem ncav cuag, cuam tshuam rau cov duab ntawm cov sib koom ua ke, txo qhov kev ntseeg siab ntawm kev sib koom ua ke. .
10.Solder pads yog txuas ncaj qha mus rau thaj chaw loj ntawm cov ntawv ci tooj liab, uas ua rau muaj qhov tsis xws luag xws li sawv monuments thiab cuav soldering.
11. Solder pad pitch yog loj dhau los yog me me dhau, cov khoom siv vuam kawg tsis tuaj yeem sib tshooj nrog lub ncoo sib tshooj, uas yuav ua rau muaj qhov tsis xws luag xws li sawv monument, kev hloov pauv, thiab cov khoom cuav.
12. Solder pad spacing yog qhov loj heev uas ua rau tsis muaj peev xwm tsim cov pob qij txha.
