PCBs

To the total cost of making a PCB from start to finish consists of several steps starting with the design, passing through the BOM and assembly and ending with the test and debug: they all are equally important aspects, each of which can determine the success or failure of the project, and none of which is immediate to take care of, especially today, where the spatial density of the components and the velocities of the signals are rising dramatically. These steps are transversal to each other: the initial design must foresee the final test phase. The “design for testability” is a crucial step for the success of the manufacturability process. This not only important from a strictly functional point of view, but also in order to develop a product at the lowest possible manufacturing cost, while maintaining an acceptable rate of defects. All these aspects, that lead to the birth of a successful PCB, must take into account increasingly numerous and challenging functional specifications. More and more mixed signal PCBs are designed in a context where the design is also bound to other, increasingly stringent, operational constraints in addition to testability, in the sense of low power, signal integrity, low noise and high density. If you misjudge any of these aspects, you may end up with a design that will not traduce as expected into the manufactured product. An inadequate layout results in problems such as electromagnetic interference, conflicts among components, limited board functionality and even total board failure. Plus, if you don’t get the layout right, you must rework it, which means manufacturing delays and added costs. In this context, TEDIEL offers consolidated experience in design, realization, assembly and test, from counseling to final production of PCBs at the state of the art.
