Perakitan PCB Utama: Panduan Pemula untuk Komponen yang Biasa Digunakan

Memahami proses perakitan PCB bisa menjadi tugas yang menantang, terutama jika Anda tidak terbiasa dengan konsepnya. Kami memahami bahwa Anda ingin menjelajahi dunia PCB, karena PCB telah menjadi bagian penting dari semua elektronik modern.

We simply cannot imagine any appliance not using a Printed Circuit Board. So, more and more people are trying to enter the industry, even the ones who have limited information about the Printed Board. In some cases, you might be a student who wanted to learn more about these amazing PCBs.

Regardless of your objective for understanding the basic concepts of the Printed Board, we have come up with an effective beginner-level guide. In this blog post, we are going to talk about the basic components of a PCB.

These components are part of all PCB types. Therefore, learning about these components would provide you with basic information about PCBs.

Main PCB Assembly – Main Components

For a PCB to power the device, it needs to have all its components in the working state. Failure in one component would lead to the failure of the entire Printed Circuit board. This would then result in the malfunctioning of the devices.

So, here are the most commonly used components of a Printed Circuit Board.

Resistor

Among the most common components of PCBs, we have resistors. In addition to being common, they are also extremely easy to understand. The main job is to resist the flow of current. In order to do so, they dissipate electric power as heat.

Resistors are available in a number of types. Moreover, manufacturers use different materials for their construction. Every type of resistor has its own advantages and disadvantages. Nonetheless, the classic resistors are somewhat similar to the hobbyist in the axial style resistors.

Both these resistors have color ring bodies and long ends. The rings are basically the code indicating their resistance value.

Capacitors

Next in line, we have the capacitors. We are sure most of you might have heard this word, even if you are new to the PCB concept. Capacitors are used universally, and all appliances incorporate them one way or the other.

In a PCB, there more resistors than there are capacitors. Capacitors are responsible for holding the electric charge for a short period. Then, they release it to the place where it is needed the circuit. Generally, is first collects the opposite charge on two layers (conductive). To sperate the layers, manufacturers use either the dielectric material or insulation.

To categorization of capacitors depend upon either the dielectric material or the conductor. Thus, resulting in a wide range of capacitors offering different characteristics. Some common types include diverse polymer capacitors, capacitance electrolytic capacitors, or the ceramic disc capacitors.

Inductors

Even though inductors are the last in the linear passive components of the main PCB assembly, yet they do hold great importance. Their main function is to store energy. However, the difference between them and capacitors is that instead of storing electrostatic energy, they save it in magnetic field form.

The current flowing through inductors helps create the energy that they store. The coil wire is perhaps the simplest inductor, you will come across. For a great magnetic field, you need a greater number of windings. Thus, there you are more inductance.

To look for an inductor on a PCB , see its magnetic core. They are wrapped around it. Remember, the magnetic core comes in a number of shapes. In addition to amplifying the magnetic fields, inductors also help in blocking a certain type of signal.

For instance, they are useful for blocking the interference in a radio device.

Potentiometers

They are a sort of variable resistors, and you will mostly find them in the linear and the rotary types. To vary the resistance, you would have to rotate the rotary potentiometer’s knob. This would move the slider contact over a semi-circular resistor.

Have you ever noticed the volume controller of an old-style radio, that is the classic example of the rotary potentiometer? The amount of current supplied to the amplifier is controlled by the potentiometer.

There is no difference in the linear potentiometer expect that the contact between moving slider contact on the resistor is linear. They are perfect especially when you want to fine-tune things in the field.

Transformers

The main objective of a transformer is to transfer energy from one circuit to another. While transferring, there is either a decrease or an increase in the voltage. In other words, we can say that voltage transformation is taking place.

The appearance is similar to that of an inductor. They have minimum tow coils of wire and a soft iron core.  For the source circuit, the primary coil comes into action. Whereas the second coil is for the circuit where the energy will reach too.

Diodes of Main PCB Assembly

Diodes are like a one-way street. It lets the current flow in one direction. The fixed direct is from anode positive to cathode negative. When it does this, it tends to offer zero resistance in one direction, whereas it has a high resistance in the other direction.

Diodes are effective to prevent the current from flowing into the wrong directions. After all, faulty current flow would damage the Papan Sirkuit Cetak . Light-emitting diode or an LED is among the popular diodes that you will find.

Transistors

Transistors hold great importance for modern electronics. In fact, they are claimed as the fundamental building blocks of compact and sophisticated electronics. There are extremely small, and you can find up to several billion in just a single IC chip.

However, these transistors are no more than electronic switches or amplifiers. Transistors can further be categories into PNP or NPN versions. The basic structure of a bipolar transistor compromises three pins including the emitter, collector, and the base.

In the NPN type transistor, the current flows from the base to emitter, it then turns onto another circuit. Thus, causing the current which is larger to flow from collector to emitter. In the case of PNP transistor, the rule is the same, however, the direction is opposite.

Silicon Controller Rectifier of Main PCB Assembly

Silicon Controller Rectifier, also famous as Thyristors, silicone controller rectifier has similar functionalities as that to a diode or a transistor. In simple words, we can say that they are two transmitters put together.

Like the above, SCR has three leads. However, it has four silicone layers. It also acts as a switch, and not as an amplifier. Moreover, you just need a single pulse in order to activate the switch. This is different from the other similar components.

They work well when you need to switch larger amounts of power.

Sirkuit terintegrasi

Ini pada dasarnya adalah komponen dan sirkuit yang menyusut menjadi wafer dari bahan semikonduktor. Sirkuit ini dikemas dalam wadah plastik. Perumahan ini hadir dalam berbagai bentuk dan warna.

Osilator Kristal

Untuk elemen pengaturan waktu yang stabil dan tepat, banyak sirkuit menggunakan osilator kristal. Mereka bertanggung jawab untuk menghasilkan sinyal elektronik berkala. Untuk melakukannya, mereka secara fisik akan menyebabkan bahan piezoelektrik berosilasi.

Setiap osilator kristal memiliki frekuensi getarnya sendiri-sendiri. Selain itu, mereka menawarkan stabilitas yang lebih, faktor bentuk yang lebih kecil dalam hal beberapa metode pengaturan waktu lainnya. Karena alasan khusus ini, kami melihatnya di jam tangan kuarsa dan mikrokontroler.
