Since every switching power supply generates broadband noise, it is even more difficult to integrate the DC/DC converter in the automotive circuit board network into the automotive control device while meeting the EMC standards of the automotive OEM. . Typically, noise from DC/DC converters and other high-speed circuits propagates and radiates through the connecting cables …
Impedance matching means that when energy is transmitted, the load impedance is required to be equal to the characteristic impedance of the transmission line. At this time, the transmission will not produce reflection, which means that all energy is absorbed by the load. On the contrary, there is energy loss in transmission. In high-speed PCB …
For electronic equipment, a certain amount of heat will be generated during work, which will cause the internal temperature of the equipment to rise rapidly. If the heat is not dissipated in time, the equipment will continue to heat up, and the device will fail due to overheating. The reliability of electronic equipment Performance will …

EMC-design of PCB board layout services shield PCB antenna module products such as GPS & GPRS modules; there are also some products with RF function modules that we will use metal shielding covers when designing: the structure is as follows (full shielding), we must focus on the interference of external signals ; GPRS module design; …
The following is the case of LLC resonant power supply, and I will share it with readers and friends. The drive uses an isolation transformer, the secondary side uses a full-wave rectifier circuit, and the loop uses TL431 type 2 compensation The main circuit
PCBA welding process mainly refers to the production process of welding PCB circuit boards prototype and components through soldering process. During the welding process, poor welding such as virtual welding and false welding are prone to occur. Virtual welding and false welding will seriously affect the reliability of the product and greatly increase the maintenance …

Printed circuit board (PCB) refers to the use of printing technology to form a conductive circuit pattern or a functional board containing printed components on an insulating substrate according to a predetermined design, which is used to realize the interconnection and relay transmission between electronic components. It is an indispensable basic component of electronic information …
The growing need for digitization in consumer and industrial electronics has driven many innovations in the PCB manufacturing process. Advanced PCB substrate materials such as epoxy resin and polyamide meet the growing demands of the global PCB market. Recycling of PCBs is now being given extensive attention to meet environmental and sustainability guidelines set by …
Using a through-hole-reflow (THR) process can save money during assembly and enables a more compact placement of components. On my iMX8 PCB I´m using a THR process for the HDMI, USB-C and Industrial Ethernet connector. In this process the through hole pads are filled with solder paste during the stencil printing. Before placing the components on …
