When it comes to PCB material selection, making the right choice for your design is important because materials can impact the overall performance. Knowing how the thermal and electrical properties impact your design before you get to the manufacturing stage can save...
PCB design and manufacturing is a complex process managing thousands of components and connections across a multi-layer board. It is of critical importance to ensure the production yield is error-free and one way to improve fabrication yields is to perform a design...
Measuring impedance and checking for faults and discontinuities on different points of a PCB trace is not a cakewalk. This is because impedance is an AC property and cannot be measured like resistance. Time Domain Reflectometer (TDR) impedance measurements are...
Cost control steps should be taken in the early PCB production stages, including the actual circuit development stage. Be aware of the process steps and cost drivers for rigid circuit boards because each process consumes additional cost in terms of process time,...
With the advancement of technology and miniaturization of devices, the heat generated per unit area on a PCB has increased significantly. Components such as ICs generate more heat when running at high speeds. To dissipate this heat away from the PCB we typically use a...
When manufacturing a circuit board, one of the most critical aspects is printing and etching the layout on the copper-clad laminates. The imaging process is central to creating a PCB layout and defines the circuit traces. While the conventional imaging process needs a...
As simple as it is, a prepreg is nothing but an insulation layer. Prepreg is a dielectric material that is sandwiched between two cores or between a core and a copper foil in a PCB, to provide the required insulation. You can call it a binding material as well. It...
While manufacturing a PCB, controlled impedance can be achieved through specific dielectric thickness and by providing the target ohms on each layer. The factors that influence impedance are the PCB materials’ dielectric, the trace thickness, width, and height from...
There are various challenges when it comes to PCB design and manufacture and one of them is retaining signal integrity. When you transmit a signal, the signal received will be subjected to distortion from signal noise, crosstalk, and other undesired effects....
