Identification:
Keypad IC mobile phone pcb par sim ic or ringer ic se kuch badi hoti hai lekin flash ic, cpu, network ic, pfo or power ic se small hoti hai. yah keypad section lagi rahti hai. basically yah CPU ke paas me lagti hai. Yah ic chamakdar black colour, vargaakar or patli hoti hai.
Works: Mobile phone me keypad ke all works ko keypad ic dwara control kiye jate hai.
Faults: Keypad IC ke kharab ho jane par mobile phone ye faults aati hai –
(A). Keypad not working.
(B). Keypad buttons not work.
(C). Some keypad button not working.
Kya Aap Practice Kar Rahe Hai ?
Humne mobile repairing course ke starting me hi aapko bataya tha ki aap khud pcb par all parts or ic identification krna practically sikhe. to continue mobile cell phone repair course ke sath practice bhi krte rahiye.
