    How important is a PCB prototype

    Contemporary printing technology has led to a significant reduction in performance compared to conductor switches on different planes, resulting in reduced space requirements and increased packaging density in electrical components. Nonetheless, modern VLSI and other multi-pin configuration devices have dramatically increased packing density, and therefore the focus of interconnected lines.

    The designer integrates all the functionality that can fit into the board. Sometimes the necessities are extensive and the board can be large and very complex. Many things are needed to get the design into the prototype phase. Reliability and functionality have priority. The number of layers required depends on the complexity of the need. Some cheap PCBs are only two layers, but in detailed applications they can reach over 32 layers. Size is also important. The board should fit into the system for which it was designed.

    The low caliper board was under extreme control. Everything should be checked during the production process. All lines and marks are re-measured to ensure density before plate pressure. The holes are drilled using very advanced equipment that must be pre-programmed for each plate. When components are added to the surface, electrical signals are again checked and tolerances checked. After making the board according to specifications, the prototype is then tested and re-examined.

    Each step of producing a PCB prototype should be carefully examined for efficiency and reliability. The board is tested independently to ensure functionality before it is integrated into the environment for which it is designed. Each step is documented and recorded. All failures need to be solved in their entirety, and in some cases a new prototype with modifications has to be built. This prototype remains under proper supervision until it is in line with expectations.
