Testing Your Printed Circuit Board Components

There are different electrical elements that make up a printed circuit board. These include transistors, capacitors, resistors, diodes and fuses. These components should function properly in order to maximize the performance of a PCB. If one of the components is damaged, the performance might be degraded. Hence, it is important to monitor and test each component.



These are made up of insulating materials. The main function of capacitors is storing energy as electrostatic field. In printed circuit boards, they enable indirect current flow by blocking the direct current flow. When direct current voltage is applied, each conductive plate stores the electric charge. The current flow stops when the capacitors are full. The capacitor type is determined by the insulating material. Some of the insulating materials that are commonly used are silver mica, polycarbonate and ceramic.

In printed circuit boards, the board itself has a capacitor with different layers of power conductor, metal conductive areas and ground conductor, which stabilize a capacitor. The decoupling capacitors in PCBs, on the other hand, reduce the noise and lessen the impacts of some components on the board.

In testing a capacitor, you should remove the other end of the capacitor from the circuit. To avoid overloading of the device, the power of direct current voltage should be matched with the capacitor’s range. When you apply the voltage, there are different possible outcomes. If there is a leakage, the meter reading will register high followed by dropping low again. If the capacitor is open or has too low capacitance, the meter will register no jump.


A resistor is a small electronic device that has two terminals. It is responsible for transmitting electric current to create voltage. An ohmmeter is used to test the resistor. You should first isolate the resistor to establish accurate reading. Next, you should connect the multi-meter to a specific resistor. Then, run a test. If the resistor is open, it will acquire an output value higher than 0.6 volts.


A diode is an electrical device that transmits current in a single direction. It is composed of two semi-conductive materials on both ends: n-type and p-type. While transmitting current in a single direction, diode blocks current in the opposite direction.

P-C-BIt can be a sensitive operation to test a diode. If done improperly, it can cause permanent damage. It is always recommended to seek help from professionals before testing any electrical components. When you are ready in testing the diode, you should disconnect its one end from the board. Next, identify the black and red meter probes with an analog meter. Then, connect the red probe to the anode and the black probe to the cathode. Set the meter reading between 1 and 10 ohms. If the diode is open, the meter will register no reading. If the diode is leaky, the meter will register two readings. If there is a forward bias, the meter will register some resistance.


Fuses are usually located at the PCB input. When there is overvoltage, the materials inside the fuse melt. Thus, it prevents the electric components from getting burn.

Before testing the fuses, make sure that the main electricity is switched off. In testing the fuses, you need to use an analog meter. You should first set the meter to X1 Ohm range. Then, place the probes either way. You can connect the black test probe to one end cap and the red probe to the other end. If the meter registers a reading, the fuse is in good condition. It does not need a replacement. If the meter registers no reading, the fuse might have an opened circuit.

Dependability of a Portable Storage Container

Container-houseWhat’s so good about metal storage containers nowadays? There are more options to choose from including portable storage container. Unlike before, you need to travel and check the different storagecontainer facilities to get the best one in your opinion. You need to see if they have what it takes to safeguard your things all day and even during weekends and holidays. If you need to retrieve something from your container, you need to travel just to get it.


Now, you can have your own storage container which also comes with tight security feature right in your property. You don’t have to go far or make the trip just to access the things that you kept inside your storagecontainer. You just need to take a few steps and you can retrieve the things you need. It is also easier for you to store away the things that you don’t need around the house but still need those for future use.

The Versatility of the Metal Storage Container

The portable storage container can efficiently keep your belongings safe and protected. You can keep a lot of things in your container and you only need to make sure that rust won’t invade your metal.

You can turn your metal container into a study room where you can have almost unlimited access to a calm and peaceful surrounding. The metal container can keep noise under control.

You can also turn your container into an office or even a place where you can do business. You can even turn it into a hobby room and play room for your little ones; but make sure that when they are playing in the storage container, there is always someone who keeps them company.

With a bit of imagination, you can turn your container into something that you really need.

More Safe and Secure

The modern storage containers are made of steel and come with a tighter security feature that you will surely appreciate. Your container is completely safe in your property and you can still choose to add more security if you still feel like you have to.

Great for Moving

If you already own a portable storage container and you need to move to another place, then all you need to do is pack your important stuff inside your container and hire a hauler to help you transport your container. It is more convenient if you can pack all of your things inside. If not, you can leave the less important ones out and hire a moving company to transport it to your destination.

Amazing Help when you are Selling your House

ContainerIf you want to sell your house without any intention of moving out until the last minute, then renting a storage container where you can store away some of your stuff is a practical thing to do. You want to make your house is presentable to possible clients and you can only do that if you don’t have so much stuff inside. You need to make the house look organized and fresh as if no one has lived in it.

Transferring your important things in a storage container can also make you feel at ease whenever someone tries to inspect your house. You can be certain that your valuables are intact with you.

During Renovation

It is hard to get on with your renovation if you have so much stuff in your house and you need to be there to see if everything goes according to your specifications. You can rent a portable container to store your things for the meantime and make the workers do their job with ease.
