After testing the production of PCB circuit boards, SMT chip processing factories need to use the equipment of SMT chip processing factories. So, you know that during SMT chip processing, the environment inside the factory is also a common accident. The fire and sound insulation equipment of SMT chip processing factories need to be equipped with waterproof functions. So what is the knowledge of fire and sound insulation products of moisture-proof PCB board manufacturers? Next, follow am.

What fire prevention technologies do SMT chip processing factories have? Do all SMT chip processing factories focus on producing SMT chip processing? Some customers may use IPC grade fire-resistant boards, but IPC generally has standards. Some customers may ask, "Is the circuit board board board made of flame-retardant materials? What are these?" That's why they don't have them. What we are talking about here is PCB board. As we all know, PCB board needs to be made of a layer of qualified PP material. If the PCB board is surface treated, will the surface resistance value of the board affect the stability of signal transmission, so that the impedance of the circuit can be controlled within a certain range. However, another important consideration is the dielectric constant of the pcb board. A PCB board needs to be printed with the same thickness of copper foil. Because the dielectric constant of the high-frequency board will be different when the thickness of copper foil is different, so when selecting, pay attention to the placement position as close as possible to the electronic components, and the data should not affect the signal flow of the circuit; Also, be careful not to affect the impedance of the power supply and the formation.
The substrate commonly used for PCB circuit boards is copper foil. Copper foil is an aluminum material, and if covered with a solder mask layer, it is also a common substrate. Because the price of the substrate is lower, compared to aluminum substrates, the price of the substrate is higher. The production and design of PCB circuit boards are usually based on FR4, with FR4 being more commonly used. What are their advantages reflected in? In terms of main materials, it is mainly used to carry the internal resistance of circuits and power lines (U-tubes, non line winding end branch optical resistance, and adjustable optical resistance). Generally, the connection resistance of each node within each square meter should be controlled between 103 and 161 ohms. The line voltage is 15-2 times the line voltage.
