Pokonza mafoni a m'manja, zojambulazo zamkuwa za bolodi la dera nthawi zambiri zimadulidwa
kuzimitsa. Zifukwa zake ndi izi. Choyamba, ogwira ntchito yokonza nthawi zambiri amakumana ndi zojambula zamkuwa
zingwe chifukwa chaukadaulo wopanda luso kapena njira zosayenera pakuwomba zigawo kapena
mabwalo ophatikizika. Chachiwiri, gawo la foni yam'manja yomwe yawonongeka ndi kugwa
madzi, poyeretsa ndi chotsuka cha akupanga, gawo la zojambulazo zamkuwa za dera
board yatsukidwa. Pankhaniyi, okonza ambiri alibe chochita koma kuweruza mafoni
foni ngati "wakufa". Ndiye momwe mungabwezeretsere kugwirizana kwa zojambulazo zamkuwa?

1. Pezani kufananitsa kwa data
Yang'anani zambiri zokonzetsera kuti muwone kuti ndi pini iti yolumikizidwa ndi
pini pomwe chojambula chamkuwa chimasenda. Mukapeza, gwirizanitsani zikhomo ziwirizo ndi enameled
waya. Chifukwa chakukula kwachangu kwamitundu yatsopano, zosungirako zatsala pang'ono kutha,
ndi kukonzanso deta ya mafoni ambiri ndi zambiri zolakwika, ndipo pali zina
kusiyana poyerekeza ndi zinthu zenizeni, kotero kuti njira imeneyi ndi yochepa mu ntchito
mapulogalamu.

2. Pezani ndi multimeter
Popanda deta, mutha kugwiritsa ntchito multimeter kuti mupeze. Njira ndi: kugwiritsa ntchito digito
multimeter, ikani fayilo pa buzzer (nthawi zambiri fayilo ya diode), gwiritsani ntchito cholembera chimodzi choyesera kuti mugwire
zojambulazo za mkuwa zimachotsa zikhomo, ndi cholembera china choyesa kusuntha zikhomo zina zonse
bolodi lozungulira. Mukamva beep, pini yomwe idayambitsa beep imalumikizidwa ndi pini
kumene chojambula chamkuwa chimagwa. Panthawi imeneyi, mukhoza kutenga kutalika koyenera
enameled waya ndi kulumikiza izo pakati pa zikhomo ziwiri.

3. Reweld
Ngati njira ziwiri zomwe zili pamwambazi ndizosavomerezeka, ndizotheka kuti phazi liribe kanthu. Koma ngati izo ziri
osakhala opanda kanthu, ndipo simungathe kudziwa kuti ndi chigawo chiti chomwe chimalumikizidwa ndi zojambulazo zamkuwa
kusiya, mungagwiritse ntchito tsamba kuti pang'onopang'ono kukwapula zojambulazo zamkuwa za gulu la dera.
Pambuyo pochotsa zojambulazo zamkuwa, gwiritsani ntchito chitsulo chosungunulira kuti muwonjezere Tin mofatsa amatsogolera
amapinira ndi kuwagulitsa ku zikhomo zowonongeka.

4. Kusiyanitsa njira
Pansi pa chikhalidwe, ndi bwino kupeza dera bolodi la mtundu womwewo zachibadwa
makina kufananitsa, yesani malo olumikizirana ndi mfundo yofananira
makina yachibadwa, ndiyeno yerekezerani zojambulazo zamkuwa zomwe zagwa chifukwa cha kugwirizana
kulephera.

Tikumbukenso kuti pamene kugwirizana, ayenera kusiyanitsidwa ngati chikugwirizana
gawo ndi ma radio frequency circuit kapena logic circuit. Nthawi zambiri, ngati logic
chigawo chatsekedwa ndipo sichimalumikizidwa, chidzayambitsa mavuto, ndi gawo la RF
kulumikizana nthawi zambiri kumakhala ndi zotsatira zoyipa. Mafupipafupi a chizindikiro cha dera ndi ochepa
apamwamba. Mzere ukalumikizidwa, magawo ake ogawa amakhala ndi mphamvu yayikulu.
Chifukwa chake, nthawi zambiri sikophweka kulumikiza gawo la ma frequency a wailesi. Ngakhale izo
zilumikizidwe, ziyenera kukhala zazifupi momwe zingathere.
