PCB design and pick and place issues

How to avoid pick and place coordinate offset in KiCad

By AP, 

            
There is a problem (or I am doing something terribly wrong !) with the coordinate system in KiCad.


When exporting fabrication outputs for pick and place, make sure you deselect the “Use drill/ place file origin” from the dialog window. For me this worked best and avoided any issues I got from JLCPCB online quote tool regarding placing components.




Even if I selected the bottom left corner of my board as origin for drill files, it did not work correctly and I got an offset when uploading the CPL file to JlCPCB:




This is a rendered image of the correctly placed components by not selecting the “Use drill/place file origin” option:

Raspberry Pi compatible, SA818 radio node
By AP,  
My new radio node that I designed last month is back from production at jlcpcb. Designed in Romania and built in China 😁. This is my first attempt using jlcpcb for the entire manufacturing chain, from PCB creation to part selection and assembly.


                            

                                
                                                                    
                            

                        

                    

                

                        

                    

                        

                            
Schematic Parity Error
By AP,  
I am already one week into the design of the PCB for my new radio node and today I discovered some schematic errors that I had to fix. Running the DRC (Design Rule Check[er]) KiCad threw some schematic parity errors which “occurs when there’s a mismatch between the schematic diagram and the physical PCB (printed […]

Today I finalzied the designed for my new Raspberry Pi Zero-based radio node. Designed around SA818 and CM108B sound codec, will replace my old dead-bug style radio node that I used for so many years.

RF prototype boards arrived today from JLCPCB. The service was, as always, very fast and flawless. Seems they have a direct arrangements with Customs because I was not required to pay anything. I ordered 100 pcs for a total amount of 157 euros, apx 1.57 euro per piece. This includes manufacturing and shipment via DHL.

This is a general purpose PCB that I designed in KiCad as a helper board for my Manhattan-style mounted RF projects. It allows connection via SMA connector (vertical or edge mount) and BNC. The two completely separated prototyping sections can be interconnected by using the SMAs in the middle or, if you want to save […]

I am not a huge fan of KiCad. However, given the limited and abysmal options that we have for free EDA packages, KiCad is quite ok, although terribly flawed in some areas. Maybe the development team should focus on some simple functionalities like support for rounded traces, net group routing, zones, a simple way to […]
