PCB slotting

1. The formation of slots during the PCB design process includes: Slotting caused by the division of power or ground planes; when there are many different power supplies or grounds on the PCB, it is generally impossible to allocate a complete plane for each power supply network and ground network...

How to prevent holes in plating and welding?

Preventing holes in plating and welding involves testing new manufacturing processes and analyzing the results. Plating and welding voids often have identifiable causes, such as the type of solder paste or drill bit used in the manufacturing process. PCB manufacturers can use a number of key stra... Read More

Method of disassembling printed circuit board

1. Disassemble the components on the single-sided printed circuit board: toothbrush method, screen method, needle method, tin absorber, pneumatic suction gun and other methods can be used. Table 1 provides a detailed comparison of these methods. Most of the simple methods for disassembling electr... Read More

PCB design considerations

According to the developed circuit diagram, the simulation can be performed and the PCB can be designed by exporting the Gerber/drill file. Whatever the design, engineers need to understand exactly how the circuits (and electronic components) should be laid out and how they work. For electronics ... Read More

Disadvantages of PCB traditional four-layer stacking

If the interlayer capacitance is not large enough, the electric field will be distributed over a relatively large area of the board, so that the interlayer impedance is reduced and the return current can flow back to the top layer. In this case, the field generated by this signal may interfere wi... Read More

The conditions for PCB circuit board welding

1. The weldment has good weldability The so-called solderability refers to the performance of an alloy that can form a good combination of the metal material to be welded and the solder at an appropriate temperature. Not all metals have good weldability. In order to improve solderability, measur... Read More

Welding of PCB board

The welding of PCB is a very important link in the production process of PCB, welding will not only affect the appearance of the circuit board but also affect the performance of the circuit board. The welding points of PCB circuit board are as follows: 1. When welding PCB board, first check the ... Read More

How to manage high-density HDI holes

Just as hardware stores need to manage and display nails and screws of various types, metric, material, length, width and pitch, etc., PCB design also needs to manage design objects such as holes, especially in high-density design. Traditional PCB designs may only use a few different pass holes, ... Read More

How to place capacitors in PCB design?

Capacitors play an important role in high-speed PCB design and are often the most used device on PCBS. In PCB, capacitors are usually divided into filter capacitors, decoupling capacitors, energy storage capacitors, etc. 1.Power output capacitor, filter capacitor We usually refer to the capacitor...

Advantages and disadvantages of pcb copper coating

Copper coating, that is, the idle space on the PCB is used as the base level, and then filled with solid copper, these copper areas are also called copper filling. The significance of copper coating is to reduce the ground impedance and improve the anti-interference ability. Reduce voltage drop, ... Read More
