Hi Aaron
As an alternative, try ¡°mebrew¡± instead of pads or square, to create insulated islands on your blank pcb.
- nibbled blank double sided pcb
- 10M¦¸ SMD resistor
- 2.2pF SMD capacitor
- modified jewel screwdriver to cut a circular pattern on blank pcb
- ¡your imagination
I prefer pcb nibbler and jewel screwdrivers, that give me advanced result with that simple technique.
Here is an example of a 40MHz crystal filter with 5032 SMD crystal
73, Pascal
