Hi, I am designing a PCB which consist of Instrumentation Amplifiers, Programmable Gain Amplifiers, Switched Cap Filters, FPGAs & many ADCs. Involves low level Analog signals. How to patrician the layout so Analog & Digital signals do not interfere.

Problems using NC in RF circuits are peculiar. Depending on the situation [ie, circuit layout, frequency of use, processes used, materials, and what not], a particular NC flux may not work with a RF circuit. Various NC fluxes leave different levels

I just buy a used Contact 3AV machine. Afer fixed some things I think the machine can be ready to run and in fact for first time the machine power up, pass all self testing, homing is done, moving of table, heads, actuator is good, pneumatic function

I recently heard (but can�t remember the source) that radio receiving antennas much smaller than the quarter wavelength or so necessary to obtain sufficient signal strength were being developed. I think the process may be based on digitally correlati

The front plate of the S15 head gives you access to the signal amplifier boards. You'll find 4 potentiometers adjusting the voltage and the symmetry of track A and B. A digital scope turned to X+Y provides an image of a circle, which is been adjusted

Justin, you will find measuring equipment at http://www.omega.com All sensor signals are in uV or mV and require a signal amplifier. If you get an amplifier with display, you can program a conversion factor for mV to board stretch and it will show a

We are currently checking parts on our boards with a digital multimeter to make sure values are correct. This process takes a large amount of time and is very in accurate Can someone please recommend a low capital budget system that is good and repea

We are going to try out a PCB manufacturer that has an Alpha Level for ensuring a flat finish on the PCB's. I am interested to know if anyone has and experiences, either good or bad on how boards treated with this process are to assemble. Is there a

Also look at IPC 7095 which is all abotu BGA processes including rework. the profile will be 100% based on your board - how many layers, how many are ground & signal, how many of those are the BGA connected to directly or indirectly, the component we
