PCB Industry Terms and Definitions– Power Integrity
Power integrity (PI) Power Integrality, referred to as PI, is to confirm whether the voltage and current of Power source and destination meet the requirements. Power integrity remains one of the biggest challenges in high-speed PCB design. The level of power integrity includes chip level, chip pa...Read more -
PCB plate percolation occurs during dry film plating
The reason for the plating, it shows that the dry film and copper foil plate bonding is not strong, so that the plating solution deep, resulting in the “negative phase” part of the coating thickening, most PCB manufacturers are caused by the following reasons: 1. High or low exposure ...Read more -
Metal substrate plug hole technology
With the rapid development of electronic products to light, thin, small, high-density, multi-functional and microelectronic integration technology, the volume of electronic components and printed circuit boards is also shrinking exponentially, and the assembly density is increasing.In order ...Read more -
Ways to find defective PCB board
By Measuring Voltage The first thing to confirm is whether the voltage of each chip power pin is normal or not, then check whether the various reference voltage is normal or not, in addition to the point of the working voltage. For example, a typical silicon triode has a BE junction voltage o...Read more -
Panel of PCB
Why need to make the the panel? After PCB design, SMT should be installed on the assembly line to attach components. According to the processing requirements of the assembly line, every SMT processing factory will specify the most appropriate size of the circuit board. For example, if the size ...Read more -
Printed circuit board
Printed circuit boards, also called Printed circuit boards, they are electrical connections for electronic components. Printed circuit boards are more often referred to as “PCB” than as “PCB board”. It has been in development for more than 100 years; Its design is mainly...Read more -
What is a PCB Tooling hole？
Tooling hole of PCB refers to determining the specific position of PCB through hole in the PCB design process, which is a very important in the PCB design process. The function of the locating hole is the processing datum when the printed circuit board is made. PCB tooling hole positioning method...Read more -
Back Drilling Process of PCB
What is the back drilling? Back drilling is a special kind of deep hole drilling. In the production of multi-layer boards, such as 12-layer boards, we need to connect the first layer to the ninth layer. Usually, we drill a through hole (a single drill) and then sink copper.In this way, ...Read more -
PCB Circuit Board Design Points
Is a PCB complete when the layout is completed and no problems are found with connectivity and spacing? The answer, of course, is no. Many beginners, even including some experienced engineers, due to limited time or impatient or too confident, tend to be hurry, ignoring...Read more -
Why Multilayer PCB Are Even Layers?
PCB board has one layer, two layers and multiple layers, among which there is no limit on the number of layers of multilayer board. Currently, there are more than 100 layers of PCB, and the common multilayer PCB is four layers and six layers. So why do people say, “why are PCB multilayers m...Read more -
Temperature Rise of Printed Circuit Board
The direct cause of PCB temperature rise is due to the existence of circuit power dissipation devices, electronic devices have different degrees of power dissipation, and the heating intensity varies with the power dissipation. 2 phenomena of temperature rise in PCB: (1) local temperature rise or...Read more -
