Team Tekno World ke free mobile repairing course mein aapka swagat hai! Main hoon Rakesh Chauhan, aur yeh humara Lesson 11 – Soldering Iron Use hai.

Pichle lessons mein humne “Testing” (Fault dhundhna) seekh li hai. Ab maan lijiye aapne Multimeter se pakad liya ki ek Track toota hua hai ya Jack kharab hai.

Ab aap kya karenge?

Aapko usey jodna hoga ya badalna hoga. Yahi kaam aata hai humara Soldering Iron.

Mobile repairing mein Soldering karna “Writing” (likhawat) jaisa hai. Agar aapki soldering gandi hai (handwriting kharab hai), toh aap kitne bhi bade expert kyon na hon, aapka kaam safal nahi hoga.

Aaj hum seekhenge: Soldering, Bit Cleaning (Tinning), aur Jumpering.

Soldering Iron Use

1. Soldering Ke 3 Mukhya Saathi (The Trinity)

Achi soldering ke liye aapko in 3 cheezon ka sahi balance chahiye:

1. Soldering Iron (Heat Source): Yeh sirf garmi deta hai. (Temp: 300°C – 350°C rakhein).
2. Solder Wire (Filler): Yeh wo dhaatu (metal – Tin/Lead) hai jo pighalkar jod (joint) banata hai. (Hamesha 0.5mm patla wire use karein).
3. Flux Paste (Cleaner/Magic):Yeh sabse zaroori hai!
   • Bina flux ke soldering “rookhi” (dry) aur kamzor hogi.
   • Flux sookhne nahi deta aur solder ko “chipakne” mein madad karta hai.

2. Sabse Pehle: Iron Ki “Bit” Ko Taiyaar Karna (Tinning)

Zyadaatar naye log yahi galti karte hain. Unka iron garam hota hai, lekin solder pighalta nahi. Kyon? Kyunki Bit kaali (Black/Oxidized) pad gayi hai.

Bit Ko Chamkane Ka Tareeka (Tinning):

1. Garam Iron ki bit ko Cleaning Sponge ya Copper Wire Ball (Jo stand mein hoti hai) par ragad kar saaf karein.
2. Uspar turant thoda sa Solder Wire aur Flux lagayein.
3. Bit kaali nahi, balki Chandi (Silver) jaisi chamakni chahiye.
4. Tabhi wo heat transfer karegi.

3. Soldering Karne Ka Sahi Tareeka (Step-by-Step)

Galti: Log solder wire ko iron ki bit par pighlaate hain aur fir board par le jaate hain. Yeh galat hai! Isse flux hawa mein ud jaata hai aur solder kharab ho jaata hai.

Sahi Tareeka:

1. Safai: Jis point ko solder karna hai, usey IPA se saaf karein.
2. Flux: Wahan thoda sa Flux Paste lagayein.
3. Heat: Iron ki chamakti hui bit ko us point (pad) par rakhein aur usey garam karein (1-2 second).
4. Apply Wire: Ab solder wire ko us garam point par (iron par nahi) touch karein.
5. Remove: Solder pighalte hi pehle wire hatayein, fir iron hatayein.

Result: Ek chamakdaar (Shiny) aur pahaad (Cone) jaisa jod banna chahiye.

4. Jumpering Kya Hai? (Sabse Badi Skill)

Jab PCB par koi Track (Raasta) toot jaata hai (paani ya girne se), toh hum ek patle taar (wire) se us raaste ko dobara jodte hain. Ise “Jumper Maarna” kehte hain.

Jumper Wire Ka Raaz (Insulation):

Jumper wire taambe (copper) ka hota hai lekin uske upar Polish (Insulation) hoti hai taaki wo kahin short na ho.

• Jodne se pehle aapko wire ke sire (tip) se wo polish hatani padti hai.

Jumper Kaise Lagayein?

1. Clean Wire: Jumper wire ke kinare ko iron aur solder blob (boond) mein duba kar rakhein taaki polish jal jaye aur wo silver ho jaye.
2. Flux: Board ke dono points par flux lagayein.
3. Solder: Dono points par thoda sa solder lagakar “ubhaar” (bump) banayein.
4. Connect: Wire ke sire ko point par rakhein aur iron se touch karein. Wo jud jayega.
5. Cut & Clean: Extra wire blade se kaat dein aur clean karein.
6. UV Mask (Protection): Jumper lagane ke baad, taar ko hilne ya short hone se bachane ke liye us par Green UV Mask (Lesson 7) lagayein aur UV light se sukhayein.

5. Desoldering (Kisi part ko nikaalna)

Agar kisi component (jaise MIC ya Connector) ke chhed (holes) se purana solder nikaalna ho, toh hum “Desoldering Wire” (Wick) ka use karte hain.

• Kaise: Wick ko purane solder ke upar rakhein aur uske upar garam iron rakhein. Wick saara purana solder “choos” (absorb) legi aur chhed saaf ho jayega.

Conclusion (निष्कर्ष)

Soldering Iron Use kya hai – Soldering ek din mein nahi aati. Iske liye haath ka “kaampna” (shaking) band hona zaroori hai, aur wo sirf practice se hoga.

Golden Rule: Flux ka use dil khol ke karein, lekin Solder wire ka use kanjoosi se karein.

💡 Aaj Ka Aapka Task – Lesson 11 (Comments & Forum)

1. Practical (सबसे ज़रूरी): Ek kharab motherboard lein.
   • Us par 10 alag-alag points par taanka lagane ki practice karein.
   • Koi bhi do points ke beech ek “Jumper” lagakar dekhein. (Wire ki polish hatana mat bhoolna!)
2. Comment (नीचे): Kya aapse pehli baar mein jumper laga? Sach batana! Comment mein likhein “Yes” ya “No”.
3. Forum: Apni ki hui soldering ya jumper ki photo khinch kar humare Forum (forum.teamtw.in) par “My Practice” section mein daalein. Hum aapko batayenge ki sudhaar kahan chahiye.
