How can P*otel? protel :) I advice u u read a bit this document. With protel only, it might be hard... :) And I heard that this "method" need several prototypes and component implementaton can cause difference as well. Like I've seen something on the inet : I
UN FARUNATELY I HAVE TAKEN pcb LAYOUT design IN VLSI IS IT BETTER WORK OR NOT CAN I CHANGE TO ANY FIELD PLEASE GIVE ME SUSSITION
what is the layout will be for , RF pcb or IC layout khouly
Hi.. I have an interesting query. Is there is any company to which can convert pcb based design into chip ? Also, is it true that every pcb can be coverted into chip ? If it is not true please give some exceptions ?
any company here ineterested with my expertise! I'm very willing to relocate!(europe, usa, singapore etc.) i'm a senior pcb layout design engineer from philippines just send pm

Hello , After I search in this forum ,I found that problem of AD7730 interfacing is a pcb layout design . Anybody can share experiance of failure or success of AD7730 interfacing , pls help me to share them. There are some question about AD7730:- 1. Which power supply is suite for AD7730 , switching power supply or linear power supply ?
Can anyone explain or point me towards any papers that have been published to describe coil behaviour beyond the self resonance of a spiral pcb coil. I have created two different length pcb coils, both with similar inductance and self resonant frequecies but viewing the impedance of the (...)
Hi All, Am using Expediton pcb and design capture SP1. I have drawn the schematic and I have used more than 6 characters for pin numbers (S1-TOP_A11) but the report writer doesnt shows the report more than 4 character. i.e S1 is device ref.designator and TOP_A11 is the pinnuumber but now i get only TOP_ from the report writer. Coul

Hi, I'm very new, but please, I need some help After designing with design View of Mentor's an schematic, compiled with CDB, and no error appeared. I tried to open in pcb, from design View, and directly from Expedition pcb, but the error Job Wizard: Failed to copy all files appeared. In (...)
Hi, I would like to design antenna for inductive coupled circuits. To be more specific, I want to connect device for impedance measuring with passive LC humidity sensors. On the sensor, capacitance is variable due the presence of moisture. Resonant frequency of the sensors is in range 20-80 kHz (I have several) and impedance measuring sy
It's not particularly a coil, rather than a short straight pcb trace. You'll have higher parasitic inductances a many places in your circuit. Unless you're targetting to a mutiple GHz microwave circuit, the note sounds rather ignorant. Strictly spoken, the inductance of a pcb trace can't be calculated without knowing the substrate height an

Hello, Recently I received a pcb stackup design from my client that I feel the design is very odd, but I'm not sure whether the design can be fabricated or not? please refer in the following enquiries: 1) Client intended to use 3 layers(1 copper foil +1 core with 1oz of copper at top and bottom) to form a lamination (...)
they are similiar in some parts. from pcb layout design to ic layout. for the floorplan, they should be the same, and the routing signals should be thought in the same way. but for the IC layout, you need to have some basic knowledge of the how the geometries being drawn into different devices. and some of the basic rules for matching devic
hi. As i heard, most of the companies, especially the big ones separate the schematics and the pcb design for different people. why is it? -because it worked 30 years ago with simplier circuits? -because it works very well? (I dont think so) -because the managers want to separate the required knowledge between employees, to easily replace

Dear Edaboard people, I wish to establish a general approach for determining the trace characteristics required for a Opto-Isolator's dry contact feature. My circuit includes a common 9-PIN D-Type and an Opto-Isolator that are connected on the pcb via various traces and vias. In my opinion, all traces should be solid on external layer (TOP) and

Hi lixnig, Did you checked it i.e.: K.
Yes you can export design rules from one pcb to another. In your pcb rules and Contains Editor there are two section. Right click in the left section where the design rules are listed and select export rules or import rules. Then another panel opens and there you highlight all the rules you would like to export. Use the same (...)
