      China Wholesale Pcb Service Pricelist - 6 Layer HASL Blind Buried Via PCB 13699 – Huihe

      Features of the Buried Via The manufacturing process cannot be achieved by drilling after bonding. Drilling must be performed at individual circuit layers. The inner layer must be partially bonded first, followed by electroplating treatment, and then all bonded finally. This process is usually used only on high-density PCBs to increase the available space for other circuit layers The basic process of making HDI blind buried Via PCB Equipment display Automatic Plating Lin...

      Design rules and precautions of Rigid Flex PCB The design of rigid flex PCB is much more complex than the traditional PCB design, and there are many places to pay attention to. In particular, the rigid flexible transition area, as well as the related wiring, through-hole design, all need to follow the requirements of the corresponding design rules. 1. Through hole position In the case of dynamic use, especially when the soft plate is often bent, the through holes on the soft plate should...

      About High-frequency mixed-voltage PCB High-frequency mixed-voltage circuit boards are pressed using different laminated materials to optimize electrical performance and improve system reliability. The biggest challenge in manufacturing this type of high frequency PCB is to match the thermal expansion coefficient (CTE) of the different materials to fit the PCB manufacturing and component assembly. Typically, such circuit designs include a combination of FR-4 materials and PTFE laminated ...

      About the impedance control In the case of transmission of high frequency signals, the controlled impedance helps to ensure that the signal does not decay significantly during transmission. In essence, controlled impedance refers to the matching of the material properties of the substrate to the characteristics of the line/dielectric layer to ensure that the impedance value of the line signal is within the tolerance of the reference value. Controlled impedance PCBs provide reliable and c...

      Impedance is the combination of capacitance and inductance to hinder the circuit under high frequency signal. Impedance is an AC characteristic, which means it is frequency dependent. In the case of transmitting high-frequency signals, the controlled impedance helps to ensure that there is no significant attenuation of the signal during transmission. In essence, the controlled impedance means that the material characteristics of the substrate match the characteristics of the line / dielectric...

      Why are multilayer boards mostly even? Due to the lack of a layer of medium and foil, the cost of raw materials for odd PCB is slightly lower than that for even PCB. However, the processing cost of odd layer PCB is significantly higher than that of even layer PCB. The processing cost of the inner layer is the same, but the foil/core structure significantly increases the processing cost of the outer layer. Odd layer PCB needs to add non-standard lamination core layer bonding process on th...
