Do not wire under the crystal oscillator to ensure that the floor is completely paved, and do not wire within the 300mil range of the crystal oscillator, which can prevent the crystal oscillator from interfering with the performance of other wiring, devic
The furnace temperature test is carried out twice a day to optimize the furnace temperature curve, and the heating rate cannot be too fast. The temperature of the preheating zone should meet the requirements, not too low, so that the flux can be fully vol
SMT workshop: With imported SMT machines, optical inspection equipment, can produce 4 million points per day. Each process is equipped with QC personnel, who can keep an eye on product quality
The steel mesh is originally made of wire mesh, so it is called the mesh board.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
Accumulated service for thousands of electronic enterprises, involving many types of automotive equipment and industrial control motherboard SMT processing services, products are often exported to Europe and the United States, quality can be affirmed by n
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
In the actual processing of damp MSD, is generally baked in accordance with the manufacturer's original packaging bag warning label baking conditions. For components manufacturers do not have corresponding requirements, it is recommended to use high tempe
Different products, the selected coil diameter is different, the opposite inductance, the DC resistance is not opposite. In high frequency circuit, DC resistance has great influence on Q value
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
