1. 0.5mm suab QFP ncoo ntev ntev dhau lawm, ua rau luv luv Circuit Court.
2. PLCC qhov (socket) pads yog luv dhau, ua rau tsis muaj tseeb soldering.
3. IC lub ncoo ntev ntev dhau lawm thiab tus nqi ntawm cov muab tshuaj txhuam yog loj uas ua rau luv luv Circuit Court ntawm reflow.
4. Wing-shaped chip pads ntev dhau los cuam tshuam rau pob taws solder txhaws thiab pob taws tsis zoo.
5. Lub ncoo ntev ntawm cov khoom siv nti yog luv dhau, ua rau kev hloov pauv, qhib Circuit Court, tsis tuaj yeem soldered thiab lwm yam teeb meem soldering.
6. Qhov ntev ntawm lub ncoo ntawm chip-type Cheebtsam yog ntev dhau lawm, uas ua rau sawv ntsug, qhib Circuit Court, solder pob qij txha tsawg tin thiab lwm yam teeb meem soldering.
7. Qhov dav ntawm lub ncoo yog qhov dav heev uas ua rau cov khoom txav txav, 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 khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob.
8. Pad dav dav dhau lawm, cov khoom siv pob loj thiab cov ntaub qhwv tsis sib haum.
9. Qhov dav ntawm lub ncoo yog nqaim, cuam tshuam rau qhov loj ntawm cov molten solder raws li cov khoom siv solder kawg thiab cov hlau nto wetting kis ntawm PCB ncoo ua ke, cuam tshuam rau cov duab ntawm cov sib koom ua ke, txo qhov kev ntseeg siab ntawm kev sib koom ua ke.
10. Lub ncoo ncaj qha txuas mus rau thaj tsam loj ntawm cov ntawv ci tooj liab, uas ua rau sawv ntsug, cov khoom cuav thiab lwm yam tsis xws luag.
11. Pad pitch yog loj dhau los yog me me dhau, cov khoom siv qhov kawg tsis tuaj yeem sib tshooj nrog lub ncoo sib tshooj, yuav ua rau lub monument, kev hloov pauv, cov khoom cuav thiab lwm yam tsis xws luag.
12. Lub ncoo pitch yog loj heev uas ua rau tsis muaj peev xwm los ua ib qho kev sib koom ua ke.
