Part ki fault ko multimeter se kaise check krte hai ? Mobile PCB board per small, big or card level parts konse hote hai ? Mobile PCB kya hai etc. ke bare aap in lessons ko sikhne ke bad definitely jaan jayenge. Mobile parts ko multimeter se check krne ke bare me hum next lesson me sikhayenge or pcb per All IC ke bare me batayange. 

Mobile phone ki hardware repairing me IC ke bare me acche se sikhna bahut jaroori hota hai. Kisi bhi part ki hardware fault ko repair 2-3 IC ko heat, reball or replace krke kiya ja skta hai. Ab aate hai hum apne lesson topic per ki mobile ke big parts or IC ki pahchan PCB per kaise kare ? PCB per IC ki karya kya hai ? Kis IC ke Faulty hone se mobile phone me kya problems aati hai etc. ke bare me janange. To chaliye shuru krte hai, PFO ic ki pcb per pahchan krna.


P.F.O. (Power Frequency Oscillator):

👉 P.F.O. Identification on Mobile Phone PCB: 

PFO IC mobile phone ki PCB board per network section me lagi hoti hai. PFO antenna switch or network IC ke aas-pas laga hota hai. Iske pas ek network capacitor laga rahta hai. Jo 2 se bhi adhik non electrolytic capacitor se bana hota hai. Ise P.A. (Power Amplifier), Power Filter Oscillator or B.P.S. (Band Pass Filter) bhi kahte hai. PFO PCB board per sabse upper laga rahta hai. Yah aayat ke shape ka hota hai.
