In order to meet customer requirements, the pass-through hole plugging process is varied, the process is particularly long, the process control is difficult, often in hot air leveling and soldering experiment oil loss; Oil explosion after curing.
With the appearance of 100 megabit bus, when the signal edge rate reaches picosecond level, the system performance depends more on the front-end design, requiring accurate timing analysis and calculation at the beginning of design. Timing analysis and sig
It has been proved that the reliability of electronic equipment will be adversely affected even if the circuit diagram is designed correctly and the printed circuit board is not designed properly.
With the development of the electronic industry, the integration degree of electronic components is getting higher and higher, and the volume is getting smaller and smaller, and the BGA type package is widely used.
The development level of printed circuit board industry can reflect the development speed and technical level of electronic industry in a country or region to some extent.
In this way, the printed circuit or printed circuit of the finished board called printed circuit board, also known as printed board or printed circuit board.
There are many kinds and numbers of holes and complex shapes of single-sided paper substrate and double-sided non-metallic holes of epoxy glass cloth substrate.
That is, on the copper foil part of the outer layer of the board to be retained, that is, on the graphic part of the circuit, a layer of lead tin corrosion resistance layer is pre-plated, and then the rest of the copper foil is etched away by chemical mea
he price of PCB is something that many buyers are always confused about, and many people will also question how these prices are calculated when placing an online order. Let's talk about the components of PCB price together.
it is at least attached with a conductive graphic, and cloth holes (such as component holes, fastening holes, metallization holes, etc.), used to replace the chassis of the previous device electronic components, and realize the mutual connection between e
Human body is a very sensitive organism, if disorderly implantation, the human body will reject many things, serious and even life-threatening, which is why ceramic circuit board is said.
PCB is one of the important components of the electronic industry, the industrial output value accounts for about a quarter of the total output value of electronic components, the largest proportion in each electronic component subdivision industry
