Re: conformal coating for oil and gas electronics
@Klaus, I already sent request from their webform seek for help if they are interested.
@Kajunbee, the place I have PTH parts, there is nothing generates heat. so i should be ok.
Does anybody know other companies in north america that are...
Re: conformal coating for oil and gas electronics
Klaus,
Thanks for reply, May I get the contact info of the company in Nurenberg please.

No it doesnt beading away.
I tried also to turn it upside down, it didn't work so far :(, maybe I should try more.
Hi all,
I am trying to manufacturer a PCBA which is required to operate on a nasty environment.
Application: downhole OIL and gas
temp:-50C to 125C, lots of shock/vibration and humidity.
the PCB is a flexible PCB, so I can not pot it. I also have bunch of PTH components. I used MG422B, two...
just bare with me, I have limited background in communication, so you might here some none-sense from me. sorry about that in advance.
I am thinking to use instead of NRZ use 4 different voltage level which are going to be translated into 4 symbols. so if everything is done right, each symbol...
Hi all,
Its been a while I am reading about forward error correction (FEC) and I am not sure what scheme works the best. My application requires to send a byte (signal). this signal after passing the channel should be decoded in receiver and it should be corrected if it has error. In this...
quartz is one of the best you can get in this class, in terms of temperature stability, .... you can use oscillator like this one: https://www.frequencymanagement.com/html/oscillators.html
I am trying to understand the operational block diagram a buck-converter of the IC LTC3824.
I am not sure about the D6, D7,and D8. I think the direction of them is backward. am I wrong?
Hi all,
I encounter a lot with the term "off-line" converter or "offline" switcher. for example I read "Optimized For Off-line and DC-to-DC Converters
today on the datasheet of UC3845. I just wonder what "off-line" does mean here? Thanks in advance.
Re: Why cap accross resistor in the circuit
cap is short circuited while u feed 50Hz input, and the resistor is just to discharge the charge accumulated on the cap in the absence of input AC voltage. what do u mean about the values? which values?
Re: What is RTOS in embedded system n how it is build in the end product?
I don't think you need RTOS, and learning a RTOS is typically a time consuming task, even if you are already familiar with micro-controller itself. But as adelmon and bsprajc and evilheart said, If you need multiple task...

When I was doing image processing, I did all algorithm test and implementation on MATLAB to just check the quality of the algorithm, output performance, and measuring the simplicity of the algorithm itself. and then I...
Thank you Keith1200rs,
How about PCB? is there anyway to simulate on that. I haven't done or seen any simulation over the PCB, is there any free tools (open source) that I can try and see if the parts are connected right on PCB and I would get the expected signals ..... ?
Hi all,
I am fairly new to simulation area of electronics parts. I have used multisim and orcad a bit. I am tasked to design circuits for high temperature application (+175 C). I am not sure if i can simulate the circuit for that temperature range and even if the schematic works out, is there...
