AZEnvy - From the idea to the finished product - A success story

Hi, my name is Niklas Heinzel and I am the inventor of AZEnvy, the world's first environmental development board based on the ESP12F with a wide range of options for every maker, hobbyist, student and developer. But the path from the idea to the finished product, which can be sold, is rocky and not always easy. But it's definitely worth ambition and to believe in what you're working on.The idea was to create a multifunctional board that is as small as possible, energy-saving and versatile. In my...

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 ...

LM317 Current Boosting Secrets

By Hesam Moshiri, Anson BaoLM317 is one of the most popular adjustable regulator chips. The output voltage of the regulator can be adjusted from 1.25V to 35V. However, the chip can deliver currents up to 1.5A which is not enough for some power applications. In this article, I will discuss two methods of LM317 current boosting, using power PNP and NPN pass transistors.[A] Circuit AnalysisAccording to the LM317 datasheet: “The LM317 [1, 2] device is an adjustable three-terminal positive-voltage re...

In industrial co...

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...

Stack-up Design in PCB

In general, PCB stack-up design mainly follows two rules:1. Each trace layer must have an adjacent reference layer (power or ground layer);2. Maintain a minimum distance between the adjacent main power layer and the ground layer to provide a large coupling capacitance; The following is an example to explain the stack-up from two-layer board to eight-layer board:I. Stack-up of single-sided PCB boards and double-sided PCB boardsFor two-layer boards, the problem of lamination is no longer due to th...
