Hey Sunny,
Thanks for the suggestion. I know Sierra quite well, in fact, they are making a board for me right now as well. They are pretty good actually, but quite expensive. I have also met Amit before in the past, small world. The only issue I have is if they have mass production...
Thank, yes I always do that.
This company does not do assembly looks like. I can find many companies which can to the flex circuit, but no one can assemble it. Based on their site, it looks like they work with an asia house.
- Looking for an advance PCB fabricator + Assembler
- Looking for an...
Hello,
I am currently working on a design which pretty much pushes the possibilities with PCB design. Currently I can only find a single company capable of fabricating and assembling the design. I can find several companies to implement the fabrication of the flex circuit, however only 2 Ican...
That's what we suspected as well so we did a quick test and broke out the motor leads on a separate cable from the power/signal lines. The same noise was still present. Would a choke on the motor leads help if they are on separate cables?
Hello,
I am using the Avago AEDR-8500-120 IC for a motor rotary controller, and I am having large noise transients on the 5Vdc into the IC, and on the encoder lines. I am a well experienced PCB design, but new to motors.
I have attached the schematic to this email. It's fairly simple.
The...
Hey Everyone,
Looking to implement a system using the Freescale KL02 series MCUs, and possibly using an RTOS such as MQX Lite. Though it seems pretty cool from what I have read, I am looking for people who has experience using this chip, and using an IDE with this (Code Warrior or Keil(using...
Hey Keyur,
The date on this connector is march 2004....that is 8+ yrs old. More than likely this connector is obsolete.
You can call them to see if they can give you a replacement part, but more than likely you're going to have to find a connector that can replace this one all together. Why...
OK so I got it thanks,
works ok, give me ballpark area...but from the pic of that other calculator...it is off.
The rogers says 90-ohm differential is ~25 mils width, this pic says 14 mils...kind of a big difference.
I guess I can choose right in them middle and be fine.

hey LM, I checked out their site and signed up but I didn't see anything like that...all I saw was a copper thinness, temp calculators...and a microwave calulator app.
I found this:

What program is this?
THanks,

Hey keyur,
do you have the datasheet for it? I couldn't find it for you either :( the ASP series exists, but that part # doesnt seem to exist. Double check the part #, or perhaps call Samtec and ask them what is up with the part number.
Finding connectors is an artform, and also the biggest...
Hey LM,
Read that article. Nice thanks! I knew of the coplanar waveguide technique, by using Saturn PCB tool, however they do not do it for differential pairs.
Do you know of a CPWG-differential pair calculator?
Thanks
Hey Loosemoose(awesome name!)
Yeah thanks for the confirmation, I have done tons of high-speed stuff but when I did the calculation for 90-ohm on a 2-layer 62 mils board, the trace came to ~40 mils...which are gigantic....I was shocked.
Basically, I never knew the plane distance effect a...
Hey Guys,
Making a wuick test board using Advanced Circuit's $33, 2-Layer Board special.
here are some of the specs:
- 6 mil trace / space minimum
- 15 mil drill minimum hole size
I need to route USB on this board, but it is a simple 1oz copper 2-layer board. Thus from bottom layer to top...
