Impamvu zigira ingaruka ku iyimurwa ryibigize mugutunganya chip

Kwishyiriraho neza kandi neza kwubuso bwakusanyirijwe hamwe kumwanya uhamye wa PCB niyo ntego nyamukuru yo gutunganya patch ya SMT. Nyamara, mugikorwa cyo gutunganya, hazabaho ibibazo bimwe na bimwe, bizagira ingaruka kumiterere yipamba, muribyo bikunze kugaragara ni ikibazo cyo kwimura ibice.

Impinduka zitandukanye zo guhinduranya ibintu zitandukanye nibisanzwe

.

(2) Kunyeganyega kwa gari ya moshi yohereza, hamwe nigikorwa cyo kohereza umusozi (ibice biremereye)

(3) Igishushanyo cya padi ntigisanzwe.

(4) Kuzamura padi nini (SOT143).

. Kwihanganira ibice nkibi, nka SIM karita, amakariso cyangwa ibyuma bya mesh Windows igomba kuba munsi yubugari bwa pin yibigize wongeyeho 0.3mm.

(6) Ibipimo byimpande zombi zibigize biratandukanye.

.

(8) Kuruhande rwibice bikunda kunanirwa, nka capacator ya tantalum.

(9) Mubisanzwe, kugurisha paste hamwe nibikorwa bikomeye ntabwo byoroshye guhinduka.

(10) Ikintu cyose gishobora gutera ikarita ihagaze bizatera kwimuka.

Kubwimpamvu zihariye:

Bitewe no gusudira gusudira, ibice byerekana imiterere ireremba. Niba hakenewe imyanya nyayo, imirimo ikurikira igomba gukorwa:

.

.

(3) Mugihe cyo gushushanya, ikinyuranyo hagati yibice byubatswe kandi kigomba kwaguka uko bikwiye.
