Good PCB Substrate Selection Makes Your PCB Design Half-successful

Many characteristics of PCB are determined by the substrate,improper selection of the substrate will not only affect some performance of the product. Such as heat resistance, product operating temperature, insulation resistance, dielectric loss, etc. It will even affect the cost of the manufacturing process, so understanding the characteristics of the PCB substrate, selecting the substrate, and choosing the substrate reasonably is one of the important contents of PCB design.However, many PCB des...

What is Impedance Control?

Impedance control (EImpedance Controlling), there will be a variety of signal transmission in the conductors in the circuit board, to increase its transmission rate must increase its frequency, if the line itself due to etching, stack thickness, wire width, and other different factors, will The impedance is worth changing, and the signal is distorted. Therefore, the impedance value of the conductor on the high-speed circuit board should be controlled within a certain range, called "impedance con...

Through-Hole Assembly

Through-hole technology (also spelled "thru-hole"), refers to the mounting scheme used for electronic components that involve the use of leads on the components that are inserted into holes drilled in printed circuit boards (PCB) and soldered to pads on the opposite side either by the manual assembly (hand placement) or by the use of automated insertion mount machines.The quality of the solder joint is important for several reasons. The solder joint is the actual connection between the component...

Basic Information about LED PCB

The LED PCB comes into being with the rapid development of the printed circuit PCB industry. Some LEDs were soldered on PCB to created lighting electronic products.As we all know that LED will generate more heat compared with other electronic parts, which required the PCB to have a better ability for dissipating heat. For these special requirements, metal core PCB are frequently used on LED PCB, especially aluminum core PCB. This is because the aluminum PCB typically includes a thin layer of the...

What is Thick Copper PCB?

Thick copper PCBs are characterised by structures with copper thicknesses from 105 to 400 μm. These PCBs are used for large (high) current outputs and for optimisation of the thermal management. The thick copper allows large PCB-cross-sections for high current loads and encourages heat dissipation. The most common designs are multilayer or double-sided. With this PCB technology it is also possible to combine fine layout structures on the outer layers and thick copper layers in the inner layers. ...

How to Ensure PCB Design Signal Integrity?

Signal integrity (SI) refers to the quality of the signal on the signal line, that is, the ability of the signal to respond with the correct timing and voltage in the circuit. If the signal in the circuit can reach the receiver with the required timing, duration and voltage amplitude, then it can be determined that the circuit has better signal integrity. Conversely, when the signal does not respond properly, a signal integrity problem occurs.With the use of high-speed devices and more and more ...

Impedance Matching in High-Speed PCB Design

Impedance matchingImpedance matching means that when energy is transmitted, the load impedance must be equal to the characteristic impedance of the transmission line. At this time, there is no reflection in the transmission, which indicates that all energy is absorbed by the load. On the contrary, there is energy loss in transmission. In high-speed PCB design, the matching of impedance is related to the quality of the signal.When do PCB traces need to be impedance matched?It does not mainly look...
