Team Tekno World ke free mobile repairing course mein aapka swagat hai! Main hoon Rakesh Chauhan, aur yeh humara Lesson 8 hai.
Pichle lesson (Lesson 7) mein humne apne “Hathiyaar” (Tools) taiyaar kar liye hain. Ab aapka mann kar raha hoga ki turant phone kholkar repairing shuru kar dein.
Safety First: ESD Kya Hai?
Lekin Rukiye! 🛑
Phone ko chhoone se pehle aapko ek “Silent Killer” (खामोश कातिल) ke baare mein jaanna zaroori hai, jo dikhta nahi hai lekin aapke haath lagate hi phone ki ICs ko jalakar raakh (Fry) kar sakta hai.
Us killer ka naam hai: ESD Kya hai (Electrostatic Discharge).
Aaj hum seekhenge ki ESD kya hai aur apne phone ko isse kaise bachayein.
1. ESD Kya Hai? (What is Electrostatic Discharge?)
ESD ka full form hai: Electrostatic Discharge.
Aasan bhasha mein, yeh “Ruka hua current” (Static Electricity) hai.
- Real Life Example: Kya kabhi aapne sardi mein kambal (blanket) mein haath hilaya hai aur “Chat-Chat” ki awaaz suni hai? Ya kisi plastic ki kursi par baithne ke baad kisi lohe (metal) ko chhua hai aur “Current” ka jhatka laga hai?
- Bas, yahi ESD hai!
Jab hum chalte hain ya kapde ragadte hain, toh humare shareer (Body) mein hazaaron volts ka current jama ho jaata hai. Humare liye yeh sirf ek chhota sa jhatka hai, lekin mobile ke nanhe components ke liye yeh maut (death) hai.
2. Yeh Khatarnaak Kyon Hai?
Aap sochenge, “Mujhe toh jhatka mehsoos bhi nahi hota, phone kaise kharab hoga?”
Yahi sabse badi galatfehmi hai:
- Insaan ko jhatka tab mehsoos hota hai jab voltage 3,000 Volts se zyada ho.
- Lekin mobile ke CPU, Memory (eMMC) ya Power IC sirf 10 se 30 Volts ke jhatke se hi kharab ho sakte hain.
Iska matlab: Aapko pata bhi nahi chalega, aur aapke haath lagate hi phone ka motherboard short ho jaayega.
3. ESD Se Bachne Ke Upay (Safety Tools)
Isse bachne ka sirf ek tareeka hai: “Grounding” (अर्थिंग). Hamein apne shareer ke current ko zameen mein bhejna hoga. Iske liye humein 2 zaroori tools chahiye:
A. Antistatic Wrist Strap
- Yeh kya hai: Ek patta jo aap haath mein pehante hain, jisse ek taar (wire) juda hota hai.
- Kaise use karein: Ise apni kalai (wrist) par baandhein aur iske taar ke doosre sire (crocodile clip) ko kisi lohe ki table ya Earth point se jod dein.
- Kaam: Yeh aapke shareer ke saare current ko phone mein jaane ki bajaye taar ke zariye ground (zameen) mein bhej deta hai.
B. ESD Mat (Antistatic Mat)
- Yeh kya hai: Ek neele (Blue) ya kaale rang ki rubber ki chatai (Mat).
- Kaise use karein: Ise apni repairing table par bichhayein aur iska ground wire connect karein. Apna phone hamesha isi mat par rakh kar kholein.
- Kaam: Yeh phone ko table ke static charge se bachata hai aur parts ko idhar-udhar fisalne se rokta hai.
4. Safety Ke 3 Golden Rules
- Strap Pehno: Jab bhi motherboard ko haath lagayein, Antistatic Wrist Strap zaroor pehnein.
- Kapde: Woolen (ooni) ya Polyester kapde pehan kar repairing na karein, inmein sabse zyada static banta hai. Cotton (Sooti) kapde best hain.
- Battery Disconnect: Phone kholte hi sabse pehle Battery Connector alag karein. (Yeh ESD se nahi, par shorting se bachata hai).
Conclusion (निष्कर्ष)
ESD safety koi “option” nahi hai, yeh ek “zaroorat” hai. Ek 200 rupaye ka Wrist Strap aapke grahak ke 20,000 rupaye ke phone ko bacha sakta hai. Ek professional technician hamesha safety ke sath kaam karta hai.
💡 Aaj Ka Aapka Task – Lesson 8 (Comments & Forum)
- Shopping: Agar aapne abhi tak ESD Mat aur Wrist Strap nahi khareeda, toh Lesson 7 ki list se turant order karein. Yeh sabse sasta insurance hai.
- Comment (नीचे): Kya aapne kabhi repairing karte waqt kisi part ko ESD se kharab hote dekha hai? Ya current mehsoos kiya hai? Comment mein batayein.
- Forum (सवाल-जवाब): ESD Grounding kaise set karein (Apne table par wire kaise lagayein), iski photo dekhne ke liye humare Forum (forum.teamtw.in) par jaayein.
Agla Lesson: Ab hum poori tarah taiyaar hain! Kal se hum apna pehla “Electronic Tool” seekhenge. Agla lesson hai: “Lesson 9: Multimeter Ka Use Kaise Karein (Mobile Repairing ka Doctor)”।
