Decoupling capacitors should be placed as close as possible to the source for the signal being decoupled. This means at the pin for ICs and near the connector for input and out signals. To remove LF transients from input and output signals, the capacitor should be placed in series with the trace.Depending on the capacitor type. If it is non-polarized, it doesn’t matter. But if it is polarized, it matters which way you connect it. For example, Electrolytic ones are polarized.Today qihe smt pick and place machine sharing Correct connection of filter capacitors in PCB design .
Commonly used filter circuits in PCB design include passive filtering and active filtering. Capacitive filtering is passive filtering. This article introduces the working principle and role of capacitive filtering in detail.
Simply put, the function of the filter capacitor is to make the filtered output voltage a stable DC voltage. Its working principle is that when the rectified voltage is higher than the capacitor voltage, the capacitor charges, and when the rectified voltage is lower than the capacitor voltage, the capacitor discharges. During the charging and discharging process , so that the output voltage is basically stable.
The filter capacitor has a large capacity, so electrolytic capacitors are generally used. When wiring, pay attention to the positive and negative poles of the electrolytic capacitor. The capacitor filter circuit uses the charging and discharging effects of the capacitor to smooth the output voltage.
In many PCB designs, I found that many friends had problems with the wiring of filter capacitors, so I made a few pictures to explain, hoping it will be helpful to everyone.
The figure below is the correct connection.
According to this painting method, the filtering effect will be much better.
If you think this is not good-looking, it is correct to deal with it as shown in the figure below. You can also find that the following treatment method is also used in some PCB designs.

What is SMT in engineering?
Surface mount technology is a part of the electronic assembly that deals with the mounting of electronic components to the surface of a PCB. Electronic components mounted this way are called surface-mounted devices (SMD). SMT was developed to minimize manufacturing costs while making efficient use of board space.Qihe SMT company develops and produces all kinds of SMT equipment suitable for world wide market, including pnp machine,reflow oven,stencil printer,pcb handling machines,and other products.

Offline Automated Programming vs Inline SMT Programming
Qihe pick and place machine can be programmed directly on the SMT equipment .
Or Coordinates can also be imported csv file through programming software.
Currently supported software such as protel,DXP,Altium Designer,Pads,Candes,proteus,DXP.
Inline SMT programming is a solution to consider for narrow segments of device programming requiring short programming times, with medium to high volume, for just one device type. tvm802a,tvm802ax,tvm802b,tvm802bx
WHAT IS SMT pick and place machine?

WHAT IS SMT ASSEMBLY LINE?
With the development of technology, future electronic products will be lighter, smaller and thinner. Traditional assembly technology can no longer meet the requirements of high-precision and high-density assembly. A new type of PCB assembly technology-SMT (Surface Mount Technology) has emerged. SMT Assembly is the use of automated machines to assemble electronic components on the surface of the circuit board. Its density, high speed, standardization and other characteristics occupies an absolute advantage in the field of circuit assembly technology. In addition, SMT assembly has a wide range of uses.
