Which assembled PCB test is most practical for complex circuits?
In Circuit Test (ICT)
1 – In Circuit Test (ICT) An in-circuit test (ICT) is the most robust PCB testing method in existence.
How are PCB design guidelines for high current applications?
PCB Design Guidelines for High Current Applications When it comes to working with electronics and associated technology, one of the key principles or objectives along with producing high quality products in record time is to follow safety principles and keep the process as secure as possible.
How much copper does a high power PCB need?
High power PCBs typically use heavier copper in order to reduce the trace width and still allow it to carry the same amount of current. A smaller trace width takes up less space on the board and makes it less crowded. Higher copper thickness can be anywhere between 35 to 50 microns or 3-4 oz. per square foot if operating at over 10 amps.
What should trace width be for high current PCB?
Traces with higher width will carry more current. Generally, it is a rule of thumb to assume a trace width of 1mm per Amp of current took for a board with standard copper thickness. As you can notice, it soon becomes unreasonable wide when a trace has to carry 10s of amps, and such a path would take up a lot of space.
What to use for high current PCB pads?
Another option you have at your disposal as opposed to using heavy copper thickness is to solder copper bus bars to the PCB pads for the high power and currents. While they may have similar width to the regular traces on your PCB, they have the capability to carry much higher currents as they tend to be much thicker.
