Fix Protel PCB design to correctly implement guard ring

Hello. I made a correction PCB, as laid guard ring. Added a jumper J1. link:--- [login to view URL] ***end_link.

Dear Sir, I am an experienced PCB designer who has over 12 years design experience on complex PCB design. I can provide you with design service from schematic entry to PCB layout. I can support your PCB fabrication also. Most of my designs are ARM-Based Platform and FPGA boards. Proved working records can be found here. I have some knowleges on EC probe design. But I can not visit the link. I can not get your documents. I guess you meant for GND copper surrounding to minimize the noise. This is common rules in PCB design. I can provide all docs you need though I am using latest altium designer. Please message me if you are interested or want to learn more. Thanks

Hi. I am a professional Electronics Engineer having smart skills in PCB design. I am interested in this task of guard ring PCB design. Contact me!

I just bid on your previous project. I think its a pretty straightforward job...fixing a PCB. I can do it for you in much less money than the bids I see below. If you say, i can provide example PCB layout to you. I know that Chinese fella will appear much more preferable to you but trust me he is ripping you off.....rest are just following suite

Hi, There is a few ways how to fix it. An easy way to remove the ground plane around the connector/trace and pin3 of U1 and cover them with a copper plane on top side connected to pin 2 of U1 in-circuiting pin2 and the signal path from the sensor. On bottom side a similar plane around the connector pins. One of suggestions: you can replace the from end chip with LMP2231. It is more expensive but just a better part with less input current, less offset and better thermal stability. Regards, DSnejko

Dear Hiring Manager, I have gone through the job posting and find it's exactly matching with my technical capabilities with Protel and willing to work on it. For last more than 10 years, I am working on product design in embedded and electronics area. I have exposure on circuit design, schematic & PCB design, BOM, components selection, Prototype assembly etc. I have developed many single/double/multi layer PCB board designs using Protel, Altium Designer etc. I have worked on simple to complex PCB designs as per requirements. I will do PCB design as per your requirement considering design standards DIN EN 50178 and EMI/EMC design points, creepage & clearance distance for CE compliance etc. Looking forward to hear from you. Thanks with Kind Regards, Ghanshyam
