CNC Milled PCBs with Manual Solder Mask - Looking for tips to improve consistency Hey everyone! I’ve been experimenting with a purely DIY PCB workflow to avoid chemicals and long shipping times. Current Progress: * **Milling:** Using a CNC with 0.1mm V-bits for isolation routing. * **Masking:** I’ve started manually applying UV-curable ink (solder mask). **The Challenge:** * **Automated Solder Mask:** Hand-coating is messy and uneven. Since I have the CNC set up, has anyone experimented with **automatic dispensing syringes** or using a **laser module** to ablate a pre-coated mask? I'm looking for a repeatable, "set and forget" way to clear the pads. * **Via Connectivity:** Manual wire-looping is killing my soul on complex designs. Are **conductive pastes** (silver/carbon) reliable for long-term use in milled boards, or is the consensus still to stick with **copper rivets/eyelets**? * **Auto-leveling:** I’m using Candle’s heightmap, but I still get uneven traces on larger PCBs.…
