best regards and good morning black ribbon diodes in primary switching area are fast switching rectifiers, approximately 99% diodes have 1N4148 diode specifications. because in high frequency switching are it needs fast recovery diodes. nearly 99% diodes in switching side are fast switching rectifiers (very few diodes are zener diodes). so we can use diodes from any SMPS's switching section
Good work carried out, if We have theory,there is no problem to.. detect fault . I read some comments I think Haseeb is your firm name and your good name is Mr. ASHRAF am I right ?

I have hot air gun I use it for some special works Otherwise i love Soldering iron I feel relaxed with soldering iron Hot air makes me crazy 🤣 specially when we want to remove one component and then we start to search the other missing components which fly away with hot air hahahahaha 😂😂😂
which one soldering iron fime to desoldering pcb components power supply cause i have one soldering iron of 30w but doesnt desolder power supply components properly it takes too long for heating..
Sir when switching mosfet of power inverter is short battery terminal are also short is very dangerous for lithium ion battery so please give us solution
Really love these smps repairs but can I ask how you knew what the diodes were as no markings. Thank you
best regards and good morning

Sir this npn transistor is comfusing me becuase is connected before the load, if i got it right.
Good work carried out, if

yes, you are right, when anyone gets idea of circuit flow, then he can fix it simply and logically
Salam. Very interesting pathfinding technique. Useful when parts are completely damaged. What does resonnant mean ?
Thank you
wa alaikum salaam brother
resonant converter is switching topogy
named as resonant converter topology
बहुत सुन्दर एवं सराहनीय
great

Sir am following you very long time. Why don't you prefer the smd hot airgun to remove smd components? You work is really awsome. 🎉🎉
I have hot air gun
I use it for some special works
Otherwise i love Soldering iron
I feel relaxed with soldering iron

@@HaseebElectronics yes sir I seen your last desoldering video. One component is fly away.
😅@@HaseebElectronics
Thanks for sharing bro 😊
Can you explain in more details the PFC circuit and how we know if it working.
Best regards.
which one temp should i use on power sipply pcb ..250 degrees or 350 degrees..????

Hello Haseeb, what a professional job! Can you tell me at 4:57 how to know if it might not be a zenner diode?
very informative sir
Thanks and welcome
Teşekkürler hocam. Aleykümselam.
Great video. A few 15:00 where you find it is an npn transistor, how do you know it is not a small mosfet?
can you plz tell what microscope set are you using ?! it has a great image quality
Very informative. Thank you!
Could you please make a video about barcode scanner ?
Nice sir
it is my pleasure
Nice
Sir, smd resistor book purchase, its very helpful different value
1206, ...
you are right, that SMD resistor and capacitor book is very useful
Excellent thanks for sharing this
Thank you and have a great weekend!
Very informative video ❤
Good job....thanks
very nice .your scientific knowledge is very high. thank you.درود برشما تسلط شما بی نظیر
❤
👍
Lovely My lectur, I behind on how to identify smp zener diode
Excellent sharing brother.
thanks a lot bhai
Sharing your knowledge to us is great to you thanks
best regards
it is my pleasure
God bless you, my dear brother
thanks a lot
👍
👌👌👍👍
