Re: Minimum Track Width for Very Long Tracks
|
I don't think there is any guidance on this unless this is a flex pcb. If you are really worried, you need to make sure that 1. You put enough screw points to prevent flexing, 2. You make sure your fr4 is thick enough to minimize it, 3. Put back means (pads or through holes) to use wires in the event it does break contact along the way.?
Hi,
Does anyone know of any guidance as to how wide very long straight
tracks should be to avoid manufacturing difficulties or breakage due to
board flexing (or any other potential problem I haven't thought of)?? ?I
have to run a couple of signal tracks a distance of 500 mm and I'm
guessing that my usual 0.2 mm width would be a bad idea, but I don't
want to make them excessively wide as that would add unwanted capacitance.
Regards,
Robert
