custom pcb boards design complaints Let's examine the footprint. Here is my list of complaints when I design the custom pcb boards. The origin point is well outside the outline of the part, this can cause it to be obscured by other parts, part is rotated 90 degrees counter clockwise, and there is no need [...]
In my first article I submitted the proposition about PCB design that a small scale designer might find it more worthwhile to design his own custom libraries instead of trying to work with existing libraries. Examples of PCB design tips Let us test this proposition by designing a circuit with only 3 parts, a pair [...]
There are three goals in designing PCBs for signal integrity and electrical performance. They are 1- PCB should be immune from interference from other systems 2- It should not produce emissions that cause problems for other systems. PCB cross talk . 3- It should demonstrate the desired signal quality. A common factor relating these three [...]
All PCB manufactures are using some special machine to control and manufacture the PCB. In the end of the project, it is quite OK if you can add some PCB file text or dimensions of PCB, stack up, copper thickness color of solder mask and plating method. Manufacture will try to import your Gerber files, because [...]
Congratulations to ourpcb group, won the military standard certification!
How do I start to create my Custom Circuit Board One of the first questions a new PCB Designer asks is “How do I start to create my Custom Circuit Board". My first project was a digitally controlled power supply for kinetic toys. I assembled the circuit on prototype boards, but designed a circuit board [...]
In my 5th article, we will examine Circuit Board Printing, and trace this missing information mentioned in my last article. OurPCB prides itself on the attention to detail in Circuit Board Printing. Good Circuit Board Printing necessitates attention to detail as small as ensuring component names are not printed on top of via's, causing the [...]
A Starter Guide to Custom Circuit Board Creation - Part 4 In this episode I am going to describe a not so unique dilemma one faces when implementing a Circuit Board Project. I am developing a simple Analog / Digital interface to a popular off the shelf micro controller development platform. These development platforms are [...]
