Copper pour hole clearance

...for mounting holes. According the specs there need to be 6.2mm clearance around the hole. In my design I have a +5V power plane and a ground plane, hence shorting these two would be bad. How to I make the sufficient clearance in the design below? ![PCB][2] [2]: /editor/20171115/5a0b5c06485cf.png....

PCB layout for non-recrangular panels

...joins (unless I put a copper cut out area over them?). Then I also get my rounded corners... The whole thing is just a part of my fully self contained electronics test bench for testing components, power distribution, and Arduino programming (via USB or hopefully Bluetooth). It all sits on a porta...

...under a microscope it's consistent and solid. Compare especially the line around U4 to the rev B board in the middle, whose silkscreen is spotty and hard to read. Routing of the internal cutouts is also quite good (although I intentionally rounded as many corners as I could in this version, after ex...

A script for moving components onto the grid in PCB layout?

...cessarily align the pads or through holes with the grid. Currently I edit (round) the component X and Y coordinates. Is there a better way or does someone have a script. Regards AlanC . Hi, Try https://easyeda.com/Doc/Tutorial/API.htm#EasyEDA-API-Plug out.. Hi, I was rather hoping not to have to wri...

Where is the Rotary shaft Potentiometer (Rotary 16mm) ?

... in the silkscreens or anything else gets allowed for and it's just a nice round number. If you really want a narrower silkscreen outline for a so-called 16mm pot then that's easy to fix. You can take the POT_BITech-TTE_P160KN footprint and edit it to make it whatever width you want. I just did: PO...

Essential checks before placing a PCB order

...or and then to forget that the pin order for a MMBF5485 junction FET going round the same SOT23 package in the same order is: Pin 1 = Drain Pin 2 = Source Pin 3 = Gate To change the pin labelling in the schematic to match the PCB footprint: select the part, press the i key then edit the order of the...

Basic 555 Astable Produces Noisy Square Waves And Then Stops Oscillating

...irucit, which should have a period of about 2 seconds and a duty cycle of around 58%, produces a noisy square wave for about 60 seconds and then finishes the last 40 seconds of the simulation at a constant voltage: Basic Astable 555 Period=2s, Duty=58% The not-that-great-looking waveform is: ![Noisy...

first time PCB maker project advice?

...ill, place a copper area (plane) on the bottom of the PCB assigned to the ground net and another on the top layer assigned to the VCC net. Run thin traces between the ground pins to connect them and between VCC pins to connect them and so remove the ratlines that otherwise can be a bit confusing. (I...

Copper area on GTL, GBL Gerbers not shown

...ith the flood drawn in. However, the flood has to have a bigger clearance around the 230V pads and tracks than the small signal pads. So user has to draw the clearance round the 230V pads and tracks by hand. When the user generates, downloads and opens the Gerbers in gerbv, the flood is not shown s...

HOW TO TROUBLESHOOT

...helpful. In the meanwhile, here are some things to consider. The layout around U6, CN2 and the relays makes your schematic hard to read. The LEDs are wired back to front. You have no power supply decoupling. Please read the manufacturer's datasheets for advice on power supply decoupling for th...

Autorouter/Copper Areas tracks and copper through drill holes that have pads on only the opposite side

... Copper area also does not recognise and keep clear the holes and a space around them if it is on the other face of the PCB to the pads with drill holes. Steps to reproduce bug: Make a component with solder pads with drill holes with the solder pads on one side of the board only (ie a 30 pin DIP so...
