Kwishyiriraho neza ibice byiteranirizo byubuso kumwanya uhamye wa PCB nintego nyamukuru yo gutunganya patch ya SMT, mugikorwa cyo gutunganya ibishishwa byanze bikunze bigaragara ibibazo bimwe na bimwe bigira ingaruka kumiterere yipamba, nko kwimura ibice.
Muri rusange, niba muburyo bwo gutunganya ibice, niba hari ihinduka ryibigize, nikibazo gikeneye kwitabwaho, kandi isura yacyo irashobora gusobanura ko hari ibindi bibazo byinshi murwego rwo gusudira. None niyihe mpamvu yo kwimura ibice mugutunganya chip?
Impamvu zisanzwe ziterwa nimpinduka zitandukanye
.
(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.
Kemura impamvu zihariye
Bitewe no gusudira gusudira, ibice byerekana imiterere ireremba. Niba hakenewe imyanya nyayo, imirimo ikurikira igomba gukorwa:
.
.
(1) Mugihe cyo gushushanya, ikinyuranyo hagati yibice byubatswe kandi kigomba kwaguka uko bikwiye.
Ibyavuzwe haruguru nibintu bitera kwimura ibice mugutunganya ibice, kandi ndizera ko nzaguha ibisobanuro ~
