Smt pick and place machine, Stencil Printer, Reflow Oven Manufacturers
Qihe Electrical Technology Co., Ltd.
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.
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.
Today we are going to share a case from the client of a TVM802B automatic desktop pick and place machine with vision from Los Angeles.
smt pick and place machine programming, it must be turned on according to the operating procedures to ensure personal and equipment safety. QHSMT tech will briefly describe the steps for starting the placement IC mounter:
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
Today we share a case from a long-term partner from Ho Chi Minh city，Vietnam.
They not only calibrating and setting up the device qihe smt equipment to customers .
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.
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 .
Why use lead-free soldering for SMT chip processing
When customers inquire about SMT chip processing, they often ask whether you are using lead-free soldering or leaded soldering. We will tell customers that both lead-free and leaded soldering are available, and the prices are different. What is the difference between leaded soldering and why should lead-free soldering be used for SMT chip processing? We will introduce the difference between leaded and lead-free soldering.
