Skills about heat dissipation of PCB design in SMT process
Skills about heat dissipation of PCB design in SMT process smt pick and place machine reflow oven stencil printer There are some skills about heat dissipation of PCB circuit boards before you use the smt pick and place machine. qihe smt will sharing you some tips today .
Quality control of power circuit boards in smt line
Compared with other types of circuit boards, the requirements of power circuit boards are high reliability and special copper thickness requirements. And these two points are difficult to control for circuit board manufacturers, so how to produce high-reliability power circuit boards?Next, author from qihe smt pick and place machine will take you to understand described from the following four aspects:
How to design multi layer PCB board for SMT PNP
Rapid proofing of multi-layer pcb boards for smt pick and place machine has the following difficulties:
How to set the illumination in the smt pick and place machine workshop
The illuminance requirements of the SMT pick and place machine workshop of the patch processing factory are relatively high, and the illuminance requirements of different areas are different. The illuminance requirements of the SMT workshop are as follows
Find soldering problems after smt pick and place machine process
In reflow oven patch processing after we finished the smt pick and place machine mounting process, some quality problems often occur, such as: cold joint, bridges, insufficient wetting, too much tin/less tin, what is the reason for this reflow soldering? how to solve it,
The following Qhsmt technology will be explained to you.
PCBA washing process after reflowing and smt pick and place process
Components controlled by the speed of the conveyor belt are continuously on the conveyor belt and the production cycle time is uninterrupted cleaning method. It is suitable for the cleaning of large quantities of PCBA, and completes all processes of water-based cleaning, water-based rinsing and drying online through different cavities.
Electrostatic protection measures before use qihe smt pick and place machine
Electrostatic protection measures and precautions for PCBA processing
In the process of PCBA processing, electrostatic protection is very important. In PCBA processing and production, good electrostatic protection can effectively protect electronic components and ensure the quality of the patch. So how to take electrostatic protection measures in PCBA processing and production
If PCB is bent before we use smt pick and place machine ？
After the SMT pick and place chip machine processing ,many factories will encounter the phenomenon of bending and rocking of the circuit board during reflow soldering. In severe cases, it may cause bad SMT phenomena such as empty welding of electronic components and tombstones. These phenomena are caused by Because of what? It is because of the uneven pressure on the board or the uneven pressure on the board, which leads to the phenomenon of bending or rocking. When the board passes through the high temperature of reflow soldering, the circuit board will become soft, and the thermal expansion and contraction of the circuit board material. The characteristics of chemical factors have resulted in bent plates and rocker plates.
How To Install a Smoke Detector which is produced by a smt pick and place machine TVM802A / TVM802B
Last time we talked about the case from a client which is the producer of smoke detector from Singapore.
They purchased a set of TVM802BX dekstop smt line for smoke detector controller manufacturing .
Now let’s sharing some tips about How To Install a Smoke Detector .
