Drill pairs for 4 layer PCB

--- Quote from: mikeselectricstuff on July 08, 2019, 12:17:59 pm ---There are typically 2 ways - specify the layer as a plane, which produces a negative gerber, or a normal signal layer, onto which you place pours.
The former can be better for single planes as it can reduce screen clutter, the latter is better if you have multiple planes and traces on that layer.

I agree the former is better and I would have preferred that method.
According to "thinkfat" that method is not compatible to JLCPCB. Unless ofcourse if there is a workaround to that.
Otherwise signal layers as discussed above would have to be done.

I remember when i did a 6 layer HDI PCB with blind vias (no burred) for a 0.4mm BGA the pcb order cost ~US$1000 for around 25 pcs from PCBway.

The boards arrived and a day later i was told the product was to change and the pcbs were no longer needed.   :palm:
