We offer PCB (printed circuit board) Design & Layout services, PCB fab and PCB Assembly services all under one roof.
NEXT is the ratio of voltage seen on the victim line transmitter end to the voltage that is on the aggressor line. Our Impedance Calculator uses a 2D field solver to calculate near-end crosstalk based on the following equation: NEXT = Vb/Va= ¼ (CmL/ CL+ LmL/ LL) Where, Vbis the ...
PCB DESIGN TOOL Impedance Calculator TRY TOOL 4.Have microvias close to the signal pads to avoid signal reflections Microviasplay a significant role in reducing via stubs, contributing to enhanced signal integrity. The primary purpose of designing microvias is to route high-speed signals through short...
DESIGN TOOL Transmission line calculator Get quick, easy and flexible options when selecting the optimum dimensions of your transmission lines. Download WHITEPAPER The ultimate guide to impedence matching Improperly matched and sub-optimally designed trace lines could substantially reduce wireless performance...
in the “Design” pulldown menu. It will allow you to add, copy, delete, and move physical layers in the PCB stackup. You can add layers for signal routing, power planes, and dielectric layers of the board. The layer stack manager also provides you with an impedance calculator as well...
Although, not often thought of as such, eyeglasses–which have been around for centuries–are wearable technology. What we commonly describe as wearables today can be traced to the 1970s with the introduction of calculator wristwatches. However, since the turn of the century this technology has...
