-One of the most common inquiries I get on the Razer Blade laptops is a "no charging issue". So is it not charging because of the battery? The charger itself? Or the motherboard? In the majority of cases, it comes down to the motherboard. Here is a list of cases when it's most likely a board issue
Another common charging issue is
So what goes wrong on the board to cause some of these problems? It can be a number of things such as
An ultrasonic cleaner is a device that is used in many fields ranging from hospitals to clean and sterilize surgical tools, to automotive mechanics to clean
certain parts, to electronic repair shops to clean boards from flux or corrosion caused by liquid damage. Ultrasonic cleaners come in a large variety of types,
but what they all have in common is that they work through a process known as "cavitation". In simple terms, the frequency of the waves through the solution create
microscopic bubbles that will implode. This creates a powerful cleaning force inside the solution. When searching for an ultrasonic cleaner for PCB cleaning
it is important to choose one that meets a few simple requirements. If you use it improperly, you can even kill a working board.
So what should you look for in an ultrasonic cleaner for use in electronics? For one, you want to make sure the size you are buying will appropriately accommodate
the electronics you plan to clean. My business foundation is predominantly Macbook and Razer Blade motherboard repairs, so I went with a 1.5 gallon, as this is the minimum size
needed to fit these boards.
Once you have determined what size you need, you will want to look for one that is heated. A temperature control is important because heat helps to maximize the
cleaning potential of the solution. For example, a repaired board will most likely be covered in flux(a compound that helps in the soldering process), but most
are in the form of a paste at room temperature. Heating the solution to a temperature such as 70 Celsius will allow it to be removed easier.
It is also important to make sure you are using the correct temperatures, for example, the most delicate components on the board are rated at a tj max of 85C,
this means they arent designed to handle temperatures higher than this for an extended period of time. We want to find a good balance between an optimal cleaning
temperature but one that also will provide as little stress as possible to the components. Another important thing to keep in mind is what the fluid you are using
in your cleaner is rated at. Branson EC fluid for example doesn't recommend going much over 71C.
The next thing you will want to look for is a sweep frequency. What this does is vary the frequency of the transducing typically by a very small percentage.
This "sweep" of the frequency assures that not one area is hit too hard repeatedly and is generally a safer option for sensitive electronic components.
Now that the basics are covered, you need to know what type of solution to put into the ultrasonic. This is also very important because you can also destroy
a good board by using a bad solution. Don't cheap out on the solution! I use and recommend Branson EC Fluid. I also mix this with distilled water,
not tap water, not spring water, but distilled. If you follow the directions on the bottle, you will see that an "optimal" concentration is around 3% of total
volume and I do follow this. There are 3,785.41 ml in a gallon, so if we take 3% of that, we will get 113.5623 ml, which is the "optimal" amount of Branson EC we should
use per gallon of distilled water.
The last thing to take note of is "time". If you have a heavily corroded board then it may need to be cleaned for longer than if you are just trying to remove flux from
a board after component level repair. Times may range from 6 minutes all the way up to 20 minutes. I personally do not recommend going beyond this time limit. Typically
you want to use the least amount of time possible to get the job done, as the longer you keep it in there, the higher chance there is for it to start taking a toll on the components.
So which ultrasonic cleaner do I use personally? I use the XTRONIC #6000-XTS 6.0 Liter "Platinum Edition". This is a very good ultrasonic cleaner for the price, that meets all
of the minimum requirements I suggest, such as temperature control and sweep frequency. It is in my opinion, the best ultrasonic cleaner you will get for under $500,
and it does work extremely well.
