pcb, breakdown voltage
yes, I checked the standard of PCB material Dielectric BreakDown Voltage data, and it shows normally it could be up to 1KV/mil, which is 40KV/mm, it is the boundary.
so how can I understand this value? can I view the material characteristic constant when voltage is...
pcb breakdown voltage
Anybody can help me to figure out some hints on the PCB characteristics under high AC voltage? It is ESD generator discharged current/voltage, the max voltage can be up to ~4KV, even higher, and the rising edge could be 0.7~1ns.
I am considering if the FR4 eproxy...
Hi, Bros
I want to do some SI simulations to the DDR2 memory with SO-DIMM slot.
I do not know the target Memory Stick information, I mean it end user would probably use any memory stick. And I do not have the SPICE, RLGC or S-parameters of the SO-DIMM connector.
But I know the IBIS model of...

espice simul
Maybe I can show you some differences between IBIS and ESPICE
IBIS models: models the parasities of a device package.It can represent the input characteristics of the device's input model, and the AC operating characteristics of device's output models.
ESpice models:models...
cadence connector
Hi, friends
I have a problem on how to model the connector to make it be used in Cadence PCB SI 630.
The connector has 230pins, and high speed differential signals can run on it. I already have the SPICE Netlist of the connector, it is a RLC network, but not for all 230pins...
using ads for si simulation
Hi, manju
Yes, your answers are quite brief and accurate.
search on google, find some docuements, seems like that AWR can do everything. System deisgn, parameters extraction, layout, simulation&analysis... amazing...
let me get some more information about it...
cadence pcb si
Hi, bros
As we know, now in industry, we have several PCB SI parameter modeling/extraction/simulation solutions, for example:
Cadence PCB SI solutions (SpecctraQuest)
Ansoft AnsoftLinks+Q3D+HFSS+Designer+SIwave solutons
Synopsys HSPICE
Agilent ADS
Mentor Graphics ADMS
etc...
EMC/EMI/ESD have so many standards, for telecommunication, for Motor, for illumination, for cable...
and these standards always need update, for example, EN 55022:1998 is going to be withdrawed on Aug 1st 2007. This will bring us some changes in the EMC test, both on process, and parameters.
so...
I think you can refer to Microsoft's Xp media center OS
You can use mouse and keyboard, even remote controller to control the PC.
any link please refer to MS's website.
it is not abnormal that only has one power plane and one GND plane on a 8-Layer board.
I also suggest you to keep the GND plane to be an intact one, per se, this will provide a intact image plane for the signal layer above and under the GND plane.
High speed signals should be placed in the...
you know, I came across a board using ADI TS201 DSPs, the spec says the impedance between GND and VCC should be 50ohm or something like that, but the actual value I measure on the board between GND and VCC is just 8ohm. That time, I thought it must be short!
But after checked all the possible...
Re: 16Bit ADC
I think IBO is right. When we are using a ADC which has more bits than the processor, we always ignore (Ground them) the low bits of the ADC.
So, here, in your situation, you just need to ignore (Ground them) the lower 6 bits.
That's OK!
