PCB high-speed signal impedance test skills sharing
For low-frequency boards, PCB is to interconnect the components in the design drawings , but with the increasing frequency, PCB has begun to play t...
Talking about the method of protecting the printed circuit board (PCB) from ESD damage
Large steel buildings, cars, mountains, and even people can survive real atmospheric lightning. Humans can also create their own miniature lightnin...
What is a PCB array? How to calculate the size of an array?
This process is called "eviction" of a single board. It is often called "step-by-step repetition". Other terms used to describe arrays are: paneled...
Length Matching Routing for PCB Busses
Shortening and folding traces takes creativity and persistence, as long as the timing budget is met.
PRINTED CIRCUIT BOARDS are becoming mo...
The key point of High Frequency PCBs design
High frequency circuit design is a very complicated design process, and its wiring is crucial to the entire design! Next, I will share with you som...
Nixie Thermometer - Finished!
Today I got the PCBS for the Nixie thermometer from PCBHERO:
Here are the two sides of a PCB in detail:
I started the assembly by soldering the c...
OPTIMIZING PCB COMPONENT ORIENTATION
With low-frequency circuits, PCB designers can place components on the board in almost any orientation they prefer. If while routing a part, a trac...
