PCB dervos medžiagos įtrūkimų priežastys po BGA pagalvėlėmis SMTP apdorojimo metu

Reasons For PCB Resin Material Cracking Under BGA Pads During SMTP Processing Cracking of PCB resin material occurs due to the presence of entrapped moisture. The reason for this is a high soldering temperature that results in an increase in vapor pressure. The cracks can also occur because the board’s thermal expansion causes the spacing […]

Ar dėl impedanso kontrolės linijos padidėja spausdintinės plokštės kaina?

Does the Impedance Control Line Increase the Cost of the PCB Board? Impedance control is an important feature that affects the performance of printed circuit boards. The manufacturer can control the impedance of a PCB board by adjusting the trace configuration and the dielectric constant of the PCB material. It is essential for board designers […]

Mikrovaldiklis ir mikroprocesorius

Microcontroller Vs Microprocessor Microcontrollers and microprocessors are two types of computer chips. The former uses semiconductor technology and is suitable for various uses, while the latter is more powerful and can execute millions of instructions per second. Both have advantages and disadvantages. Microcontrollers are cheaper and require less memory and computing power. Microcontrollers are more […]
