The steel mesh is originally made of wire mesh, so it is called the mesh board. At first it was nylon (polyester) mesh, and later due to durability, barbed wire appeared. Copper wire mesh, and finally stainless steel mesh. But no matter what the material
High-end equipment can be attached to precision shaped parts, BGA, QFN, 0201 materials. Also can be template patch, loose material hand. Sample and size batch can be produced, proofing from 800 yuan, batch 0.008 yuan/point, no start-up fee.
Adhering to the high quality products, fast delivery, perfect service, good reputation, flexible marketing as the basis for market competition, business has expanded to Europe, America, Asia and Australia and other countries and regions. The goal of the f
Adjusting the running view point of the scraper to 45° in the printing direction can significantly improve the imbalance of different steel mesh opening directions of the solder paste and damage the fine-spaced steel mesh opening; The scraper pressure is
In the process of patch processing, in order to ensure the welding quality of printed circuit boards, we must always pay attention to whether the reflow process parameters are reasonable. If there is a problem with the parameter setting, the welding quali
Quality control of electronic processing is an important step to ensure product quality and production efficiency in electronic processing plants. Taking the reflow process as an example, although the temperature in the furnace can be controlled by the fu
In addition to labor costs can not be compressed, production efficiency will also be seriously reduced, SMT proofing small batch processing due to a small amount of production line just started to stop, which undoubtedly has a great impact on production e
When the PCB enters the insulation area, the PCB and components are fully preheated to prevent the PCB from suddenly entering the welding high temperature area and damaging the PCB and components.
In the first manned Apollo spacecraft, for example, an electrostatic discharge caused an explosion that killed three astronauts. Electrostatic discharge (ESD) in the process of gunpowder manufacturing, resulting in explosion casualties often occur.
the components on the PCB should be evenly distributed, especially the high-power devices should be dispersed to avoid local overheating stress on the PCB when the circuit is working, affecting the reliability of the solder joint.
Pre-welding quality inspection also includes: PCB electronic assembly design audit/or review; Audit/or review of welding process plans and procedures; Identification of outsourced units such as printed boards, components, welding process materials, and ac
Right-angle PCB board is easy to produce a card during transmission, so when designing PCB board, it is necessary to do arc Angle processing on the board frame, and determine the radius of arc Angle according to the size of the PCB board.
