Printed Circuit boards (PCBs) are an essential part of an electronic device. PCBs’ function is to supply connection and wiring mechanisms for different components of a motherboard or an electronic device. In the past, PCBs were used in devices that limited functionality; therefore, it was easy to manufacture them. As a result of innovations, modern electronic gadgets are built to perform multi-tasking and require PCBs that are compatible to perform more complicated functions. In this article, we will discuss the multilayer printed circuit board (PCB) and the benefits of using them in modern electronic gadgets along with their use in the equipment of different industries. The simpler electronic gadgets with limited functions are composed of single or double-layered PCBs. Still, for more sophisticated electronic gadgets like motherboards of modern tablets or cell phones, multiple layer PCBs are needed. Multilayer PCBs are only capable of fulfilling the requirements of these modern and sophisticated electronic gadgets.
Every electronics device is built around PCB. It is an essential part that provides rigidity, thermal dissipation and even brings additional functionality. PCB enables assembling and robustly soldering components. There is no doubt that how good PCB depends on the designer and manufacturing quality. You can make a perfect circuit design, but if PCB is crappy, no manufacturer can help even with the highest precision. All steps from idea to the finished product must be treated with high standards no matter if this depends on you or the second party. PCB manufacturing is a significant step. Depending on board quality, it depends on whether it will be easy to solder if dimensions and holes markings will be within specs. Previous actions influence the automation of further processes of assembly and testing.

Electronics design is a specific niche that involves lots of building steps and expertise. Each electronic device has overcome many manufacturing and refining cycles until it is safe to use. Blends within the environment have necessary and useful features and are much supported. Everything starts from the need for functions electronics can provide. A simple LED lamp is a complicated product that needs to last, operate within specifications, and overcome certifications to be safe to use as a home appliance. It is hardly achievable by a single person. The core of almost every electronic device is its working circuit laid on PCB. Let’s go through PCB manufacturing processes to see what steps are usually involved until design reaches production.
Designing, prototyping, assembling, and testing new electronics-based ideas require high-level expertise, instruments, and proper source channels for materials and parts. Hardly any small businesses can cover all PCB building cycles from design to working prototype. Today when the world is ticking at a fast pace, most of the labor is outsourced. Such practice is standard within a software creation, as there is lower risk – everything can be fixed and modified at any stage. Hardware is a bit more complicated because mistakes made at the initial stage are passed to the following cycles. This is why companies, hobbyists, and enthusiasts usually tend to take most of PCB manufacturing and to assemble control to ourselves. The cost and capabilities of PCB assembly service at PCBWay PCB assembly has never been so cheap. As an example, let’s look at one of the leading PCB manufacturers- PCBWay. They are offering a broad spectrum of PCB related services including prototyping of different types of PCB boards, assembly, testing, and even design when you basically need to provide guidelines of device and care is taken from designing to the finished working device.
Printed circuit boards are the most essential components in all electronic appliances and products. Most of use these boards every day without even realizing what they are. If you ever open up your broken remote, you will see a circuit board which is infused with a lot of wires; it is called the printed circuit board. They are an integral part of electronic devices and are used in our everyday lives. They have many lines on them and continue to be infused in all electronic devices until this day. These boards are responsible for connecting the product to the wires via copper sheet. They are commonly used by the following industries:
Are you in the process of designing your following product? We are sure you want to get every detail right, which is why you can benefit from a flexible PCB. These boards are bendy and capable of accommodating any design. However, you should ensure to pick a reliable flexible printed circuit board manufacturer, and that is not always an easy task. Take a look at this simple but informative guide on flexible PCBs, and learn how to pick the right company to order from today. 1. What Is a Flexible Circuit Board? A flexible circuit board is a PCB that has been specially designed to be flexible. Flexibility is the essential feature of these boards, and it is the reason why they are becoming so popular. Flex PCBs have a wide application field, including but not limited to: You can use them wherever you need adaptability from the circuit board. If you realize that you require a bending circuit during the assembly process, flex PCBs will be the ideal solution.
Many PCB manufacturers offer good quality PCBs for a low price. Anyway, there may be lots of small things that may lead to a few inconveniences if your choice isn’t the best. Of course, the primary source to check out is the Internet. Customer feedback may be a good starting point to evaluate the PCB manufacturing process of the chosen vendor. Other sources worth checking are the social media, colleague recommendations, or other influences. Sometimes there is nothing wrong with trying any manufacturer with some small batch and evaluating PCB manufacturing process and building quality by yourself. There may be a different experiences for different people, and what is bad for one may be suitable for others. Evaluating the quality of delivered PCB If you decided to try a new PCB manufacturer, there are some key points that you may want to check when boards are received. Most of them are PCB quality checks. You may go through several aspects, such as: These are small and basic things that may influence the choice of PCB manufacturer. The PCB quality is the key to a successful build of the electronic device. Design your PCB while keeping an eye on manufacturer requirements…
The term circuit technology usually refers to the various techniques used in the manufacture of electrical circuits. A large number of devices that are used today make use of printed circuit boards (PCBs). These devices provide mechanical support for the various components present within the given device and the components’ electrical connections. The electrical connections present on the PCB are made out of copper sheets laminated on a non-conducting material. Initially, a large copper sheet is laminated on the board, and then the sections that are not required are removed. Various techniques are used for the removal of unwanted copper. Some of them are: Silk Screen Printing: In this technique, an etching-resistant ink is applied to those required areas, and the remaining part is etched off. Photoengraving: Here, a photomask of the circuit required is prepared using the desired software, and then it is applied to the blank PCB. After this, the portions that are not required are etched off. PCB Milling: In this technique, a mechanical milling system that can work on 2 or 3 dimensions is used to remove the copper. The milling system is controlled by software. In some other techniques, only the required copper is added…
TDA7313 and TDA7315 are digital controlled audio processors used in applications where digital control of audio is needed. TDA7313 and TDA7315 are pretty the same just TDA7313 is more complex by having 3 stereo input channels and two outputs (front and rare). Both chips have volume control (step=1.25dB), tone (bass and treble) balance, independent faders for each output processor. Also, there is loudness functionality. TDA7313 and TDA7315 have low distortion and low noise, making them ideal for quality audio applications for car audio and Hi-FI systems. MCU can control both chips via the I2C(TWI) protocol. This makes it easy to interface microcontrollers with additional features like LCD, buttons. Or control directly from PC using RS232 or another interface. Both chips can be found in DIP or SO packages. Here are Eagle libraries of both digital audio processors that I have made. tda7315.zip(2kB) tda7313.zip(2kB) I have intent to make a control board with TDA7315 with LCD and button control using an Atmega8 microcontroller.
