PCBA placement process control
In PCBA chip processing, the amount of solder paste, chip glue, and component losses should be managed as one of the key process control contents. PCBA processing and production directly affect the quality of products, so it is necessary to control factors such as process parameters, processes, pers

PCBA processing requirements for plug hole design
Plug-in processing is a process of PCBA processing. Inserting components are generally processed by wave soldering. Since the wave soldering time is very short (3~5s), if the ground/electric layer is connected to the jack, the tin will be poor. Will cause poor soldering. Then if you want to circumve

SMT processing technology requirements for PCB design
Good SMT processing quality is inseparable from good PCB design. If the characteristics and requirements of SMT production equipment and process can be fully considered in PCB design, then SMT processing can achieve twice the result with half the effort. So what are the requirements for SMT processi

Where is the difficulty of multi-layer board proofing?
Everyone knows that the cost of multi-layer board proofing is much higher than that of single-panel proofing. Why is there such a big gap? That's because the manufacturing difficulty increases as the number of boards increases, and the cost will definitely increase. So where is the difficulty of mul

Why do you want to design the circuit on the board to be curved?
We will find that the circuits on the board are curved. Why should we design this? Three reasons are given below. First, if the lines in the board are designed to be straight, the board area will increase by several times. In today's era of pursuing exquisiteness and compactness, the area of the

What are the factors affecting PCB impedance?
When the line is less than 25 mm from the edge of the board, the line impedance value is 1~4 ohms smaller than the middle of the board, and the impedance value is less affected by the position when the line is more than 50 mm from the board edge. Next, it is recommended to preferentially select the
