  • Proper Stack-Up in a Multilayer PCB to Reduce Noise Coupling and Improve EMI
    by means of the parallel plates. in the PCB, induce noise on the signals passing through the power bus (vias) and. radiate from the edge of the board. The present study focuses on the analysis of. the noise that propagates from a power plane to another power plane due to their. proximity. To mitigate
  • PCB Repair Station Built on Highly Accurate Gantry Reduces Scrapped Boards
    Application Story, PCB Repair Station for Testing. Home > Resources > Automation Application Stories ABOUT US | SITE MAP |. PCB Repair Station Built on Highly Accurate Gantry Reduces Scrapped Boards The rigors of pass-fail are not just the pressure-cooker of classroom angst in the world of education
  • SMD Resistor Thermal Analysis
    combination of the thermal impedance of each layer of the. composite structure. This can be represented as: tot := sub + met + sold + pcb + pre. Because the resistor is typically supplied as a component to the manufacturer of the. circuit it is convenient to separate the calculation at the solder to chip

  • BGA Socket with Heatsink for High Power Devices
    The classic function of a socket is to provide a connection mechanism from the IC (Integrated Circuit) to the circuit board with as little electrical load as possible. This allows the IC to function as it is soldered into the PCB (printed circuit board) but can be replaced by another. Download
