I have to design PCBs sometimes in my work, but I have no supervisor or someone to ask. I have to do on my own. And I have no idea how good or bad I am. So, I would like to know how long other experienced people take to design PCBs for my self-assessment and goal.
Hi, I'm fairly new to pcb development and manufacturing. I placed an order for 4 different sets of boards from jlcpcb, which required exposed traces on the bottom so I left out the bottom soldermask during Gerber generation. Everything looked fine in their viewer with exposed traces etc.
Fast forward a few days for shipping and the entire bottom layer is covered in a soldermask completely defeating the point of the board.
Is leaving out the bottom soldermask on me, or should I complain?
Also if anyone has any suggestions on removing soldermask I'm all ears.
Hello, I'm designing a small device that uses an ATtiny-24A with a LoRa and GPS module to track its location. This will be my first project with SPI so I was wondering if everything is wired correctly. Am i missing some pull-up/down resistors? Does the programmer (I will be using a raspberry pi) need some sort of protection? Can the LoRa module (868 MHz) use the same antenna as the GPS module?
Perhaps I will remove the boost converter since a cr2032 already gives 3V.
The 47uF caps are there for when the radio modules suddenly need more power to transmit/receive data.
So my professor in electronics 1 course is requirijg us to use cadence virtuozo (through a university license) to simulate for component parameters, and simulate simple circuits like full wave peak rectifiers. I need a software other than cadence to verify my work because i am starting to question myself with this cadence. It gives such weird results that i started to doubt in myself especially since i changed my major from something i was good at to computer engineering because its what i really want (or so i thought at the time). So anyone got any tips?
Who would be the first person I talk to if I wanted to get a PCB design for a eurorack module idea that I have. Would I need to first employ a circuit designer, then a PCB designer, or do engineers have experience in both areas?
