When choosing a Bluetooth speaker, I hesitated to buy ¥1688 Beats or ¥199 Sounds Beehive 2S+, and later bought “Yuande†on the ground that “anyway, just listen to a ring†and found out, “Although just listening, But I can't accept this ring." So he bought a pill again. Pill+ is Beats By Dr. Dre's third-generation Pill product. It was also the first speaker to be launched after Beats was acquired by Apple. (In fact, there was a Pill XL, but it was all recalled due to security risks.) ). There are indeed many Apple genes in product design. If the governor is a loyal fan of side B, I also provide you with a video of pastime. No reviews yet, come and grab the sofa!

What is a PCB and its components?
The Chinese name of PCB is printed circuit board, also known as printed circuit board. It is an important electronic component, the support of Electronic Components, and the carrier of the electrical connection of Electronic Components. Because it is made by electronic printing, it is called a "printed" circuit board.  PCBA one-stop service,PCB component ,professional PCB factories ,Pcba Assembly and Part, turnkey pcb assembly HAODA ELECTRONIC CO.,LIMITED , https://www.pcbhdi.com
The perfect match for the large base monitor: Sounder's sound cell 2S Bluetooth speaker I think that now mobile phone charging is developing for wireless charging, so this time considering the formation of a completely wireless desktop environment, with wireless headphones, speakers, wireless mouse and keyboard Fun games (of course not limited to games), just want a little more concise desktop.

The PCB board has the following three main types of division:
1. Single panel
The single panel is on the most basic PCB, the parts are concentrated on one side, and the wires are concentrated on the other side (when there are SMD components and the wires are on the same side, the plug-in device is on the other side).
2. Double panel
Double-sided board This type of circuit board has wiring on both sides, but to use wires on both sides, there must be a proper circuit connection between the two sides.
3. Multilayer board
In order to increase the area that can be wired, multi-layer boards use more single or double-sided wiring boards.
PCB features
The reason why PCB can be used more and more widely is that it has many unique advantages, which are summarized as follows.
1. It can be high-density. (HDI PCB)
For decades, the high density of printed boards has been able to develop along with the improvement of integrated circuit integration and the advancement of mounting technology.
2. High reliability.
Through a series of inspections, tests and aging tests, the PCB can work reliably for a long time (usually 20 years).
3. Designability.
For PCB performance (electrical, physical, chemical, mechanical, etc.) requirements, printed board design can be achieved through design standardization, standardization, etc., with short time and high efficiency.
4. Manufacturability.
With modern management, standardized, scaled (quantitative), automated and other production can be carried out to ensure product quality consistency.
5. Testability.
A relatively complete test method, test standard, various test equipment and instruments have been established to detect and appraise the eligibility and service life of PCB products.
6. Assemblability.
PCB products are not only convenient for standardized PCB assembly of various components, but also for automated and large-scale mass production. At the same time, PCB and various component assembly parts can also be assembled to form larger parts and systems, up to the Box Build Assembly of the whole machine.
7. Maintainability.
Since PCB products and various component assembly parts are designed and produced on a large scale, these parts are also standardized.
PCBA is actually a PCB where components are assembled. The core part of all electronic products is composed of PCBA; the realization of all functions is inseparable from PCBA. Taking a desktop computer as an example, the units inside the chassis do not contain PCBA except for the heat dissipation part, and all the remaining functional units have PCBA. There are PCBA in the hard disk and power supply. The display other than the host has a display driver board (PCBA) and an LCD screen, and there is also a PCBA inside the LCD screen. There is also a small PCBA in the mouse, keyboard, and even the Bluetooth receiver of the wireless mouse and keyboard. Therefore, PCBA is the basic unit of all functions in the electronics industry.
PCBA is the most important part of all electronic product components, similar to the neural network of the human body. The brain of electronic products: CPU is installed on PCBA. The lifespan, operating speed, reliability and stability of general consumer electronic products have the most direct relationship with PCBA. Therefore, the quality of PCBA is also the most direct determinant of the overall quality of electronic products.
