I am making a board (111mm x 146mm, 4 layer) with a PZT3904 transistor. It has a heat sink pin and I am uncertain as to how much copper I have to put around that pin so it has adequate heat dissipation. The datasheet says I need the following for a maximum of 1 watt heat dissipation:

Hello,
I need to import a PADS .pcb file (binary) from Siemens into Altium or KiCAD. Do you have any idea? I don't have the full license of PADS layout. I know that Altium can import only from PADS ASCII PCB.
The file I'm interested in is here...
Hello everyone,
I 'm now designing an adapter PCB using Altium Designer. I want to use some vias to reach the figure in picture 1, but now I always get it like in picture 2. I'm new to PCB design and also new to Altium Designer. I don't know why there is always the space around the vias like in...
Good day, all
This is my first attempt at doing this. I want to try my hand at creating a consolidate PCB. Also I am using Eagle for this, again a first time user.
My Goal: a single compact PCB with the Atmega32u4 & BNO080 connected together via I2C, an ICSP header for programming the 32u4, a...
Just found this on alliexpress and I need more then 100 of them. They say it is original but to be honest doesnt look like that. Any of you can help me please. Thanks.
Here is Link .
So I am switching out custom motor controllers for an ebike. But need help identifying the purpose of the wires indicated on the pcb.
In the pics I have highlighted the appropriate acronyms with its wire color. As you can see right off the bat I have one problem. One controller has 6...
Hello,
I was thinking to try and do my own PCB layouts myself, and then generate the gerber files so I can give them to my PCB manufacturer.
But I never used such a software and I would like to ask this forum which one I should use?
It should allow me to design layouts from the smallest. To...
Thanks for everyone help me.;);););)
Now my new project 3D model is done.
I build it with my teacher, and this project takes me a month to do it.
Hooo! Feel free to leave a comment.

As you can see, the thickness of the power line, blue line and red line on the circular pad is different. Is this feasible? The line to the left of the right square pad and the line above it are also different in thickness. Is this OK? I heard that this situation will reflect under high...
To anyone who can help me, PLEASE!!!!!
I have a circuit board I am working on that is to have 3 outputs...
12V at 1-2A, 6.8V at 1-2A, and 33V at a higher amp rating, about 3-4A...

Hello!
I am using FCPF220N80 MOSfet for 400 Volts operation. it is rated for 800Volts. I have one doubts though, The clearance(distance) between the drain and source pins of the mosfet is only 2.5 mm. Will it be able to sustain without any damage...
Hi everyone!
I am new to PCB design. I design circuit manually but basic one now I want to do more serious circuit design using the simulator and design software. Please suggest me good beginning software and easy one so that I can understand and master it myself. Thanks!:)
I've recently started teaching a bunch of school kids about electronics basics. Get them interested while they're young. Since then I've designed a few simple circuits to show them and looked into getting them professionally made. I thought it would cost loads, but I looked into it and wouldn't...
