    Prepreg PCB Impedance Control

    Prepreg PCB Impedance Control

    Again, unmatched impedance in different points on the Prepreg PCB surface increases the signal reflection to a certain extent that the real signal gets totally distorted. It declines the efficiency of high-frequency PCB projects. That’s why you need to consider impedance matching in this PCB manufacturing.

    What Is The Dielectric Constant Of A Prepreg PCB?

    The dielectric constant of a prepreg PCB covers a wide scale. It varies from 3.5 to 10 at 10 GHz frequency. This value always does not remain fixed in the case of prepreg materials. You can notice different DK values before and after the lamination process.

    A low DK is convenient for ensuring a low dissipation factor and high transition temperature. Besides, it also affects the CTE of prepreg materials. In a multilayer PCB stackup, variable DK is effective in many ways.

    Prepregs having different dielectric constants can be used in separate layers. This develops the robustness and electrical properties in the PCB layers. That’s why prepreg PCB has turned into a reliable choice for high-layer count PCB projects.

    How To Etch A Prepreg PCB?

    PCB etching is a crucial part of the prepreg PCB fabrication process. There are multiple methods of PCB etching. Like chemical etching, laser etching, etc. But concerning the budget constraints and manufacturing scale, the chemical process is the most worthwhile etching technique.

    You have to follow the instructions provided below to ensure a faultless chemical etching in the prepreg PCB.

    • As etching is a process that eliminates unnecessary copper from the PCB surface, you must cover the required zone to avoid the removal of essential portions.
    • Then place this circuit board in a toxic chemical solution like ferric chloride for around half an hour. You should vary this time based on the strength of this standard solution. Sometimes, cupric chloride is also used in this process, but ferric chloride delivers better toxicity and is more time-saving.
    • When all the unwanted copper gets dissolved in chemicals, pick the board and wash it through the water.
    • Rub it by applying alcohol and then dry it up properly.

    PCB Etching Process
