This Post is Explained we'll talk acer laptop repair  about how to test an integrated circuit there is many integrated circuit type the response a train see not separate procedure procedure and many thing if you see something like this that's me Pisces damaged I need to test it is already damaged you need to change it or you can't check the temperature of temperature acer laptop service  too high that's me also I see is damaged what is inside I see the voltage you can see there is mean thing voltage input voltage output sony laptop service  ground signal input signal output this is the main thing for every integrated circuit now we will make some tests for this power I see this using nano station I always said 1212 as you see this 8 pin until a circuit there is pin number Seven's voltage in input and pin number one is voltage output and the pin number thing round pin number four is feedback and the five physical comparator and pin number eight is Dell laptop service  V base now we'll test it using normal of a meter as you see here we check pin number seven is voltage supply or a voltage input it's coming from nano adapter is 24 voltage so input is okay and we'll check input output output voltage this pin number lenovo laptop service   one is given 5 volt pass mean this is okay this is the simple way to test integration circuit as you know you must have the schematic diagram for the integrated circuit and you must know each pin what's shown in the schematic diagram  laptop repair services voltage input output ground and etc another pin thank you for watching if you liked it join our channel please thank you
reflow best laptop repair  properties of how the surface mount components act so put heat on there and a little bit of solder on the ground pad here and if you get it just right kind of hard to show Eric there it is so you just got to pull away just quick enough and it'll sit in the hp laptop service   right spot and you don't need to hold it or anything like that and then that's a perfectly placed component so I'm not using a fine tip at all we are lenovo laptop service   using the standard chisel tip with this I I've only used two tips for this whole thing and if you really wanted to you could use this chisel tip for everything to mount on this including these uh LEDs here the 50-50 LED or the the crystal and it's capacitors asus laptop repair   I just use the same method when I'm hand mounting them it doesn't change at all it's very easy to do in fact once you get used to this all I think most laptop keyboard repair  people that switch over from through-hole will find that this is actually a lot easier to work with you can see here in pull passes off and change them out and test them on the board really easy and that comes in handy when you're dell laptop service  doing them you know here's a finished this is one of my electrode Nativity ones going from the breadboard to the final PCB due to hp laptop service  the ground plane and the change in the reactance of the basically of the traces and everything I had to adjust the components ever so slightly to get my oscillation just right so that's kind of a lesson there of the differences between through-hole components and surface mount components when you're moving from a breadboard acer laptop service   to a PCB but that's a different video entirely and I hope you found these little tips and tricks for doing surface mount soldering hopeful so I will link to some other videos especially Mike's video on the component placement that's  Laptop service  an awesome video and I will link to some soldering equipment here like the there you go you can see the vacuum pickup tool and my hot air station  toshiba laptop repair and yeah I mean that's basically got get yourself a nice iron with a good tip flux lots of flux good solder some solder paste if you intend to do it and some cleanup tools and laptop repairs  it's really easy to work with these types laptop repairing  of components I'll link to those other channels and if you found this video helpful go ahead and give me a thumbs up and share it or leave some comments it will really help my channel out and thank you goodbye English (auto-generated)
