Can I Generate Gerber File From PDF?
Hi,there is a PDF on my hand, how can I generate gerber file from PDF?
As the impedances of the PCB is so high, the advantage is actually quite small. You get the most benefit from grounded metal shields around the circuit; usually the chassis. If this can't be connected to signal ground, you may want to design a second floating shield inside.
For audio work though , the capacitive reactance will be low to decrease your concern. inductive reactance of traces will likewise be negligible in effect . This is not to say that one can ignore good housekeeping practices . Theorily , any circuit with gain at or over unity can be made to whistle or suffer from deleterious effects accidentally , given enough bad engineering .
For most audio frequency circuits , a pcb will cause no more hassle than hand wiring . High gain circuits can give fits. Sometimes the use of all grounds connecting back to a central point will eliminate loops . good ground planes can help eliminate problems , while bad ones can cause problems.
The dimensions of the stitched side-to-side vias and areas can form resonant circuits or cause problems at rf frequencies.
