Capacitive Electrode for Concrete Slipform

@MuhammadUzair16

Hi I am an embedded systems engineer with over 16 years of experience in PCB design, sensor electrodes, and production-ready hardware documentation. I understand this is an electrode, not a normal circuit board, so I will follow the unusual solder mask and isolation requirements exactly. I can prepare both KiCad 7/8 variants: FF-CAP-100 with the guarded active plate and FF-CAP-100-NG as the unguarded control. I will ensure there is no exposed copper on the front face, the ACT via is at the plate centre, ACT/GRD/SHD remain isolated, the back pads and labels are correct, and the front side stays clean with no silkscreen. I will generate the KiCad source, Gerber RS-274X and Excellon drill files, check the mask layers carefully, then get the JLCPCB/PCBWay quote and confirm the total cost with you before placing the order. I will also ask the fab for the nominal solder mask thickness in microns and report their answer. One small point to confirm: for the NG variant, do you prefer the GRD pad omitted or left present but unconnected? Please contact me to discuss details.

Hi there, I read your offer carefully and understand that this is a capacitive sensor electrode PCB, not a conventional circuit board. I will follow the unusual requirements exactly, including fully solder-mask-covered front copper, the centered ACT via, electrically isolated plate/guard/shield nets, no front silkscreen, no conformal coating, and the intentional removal of the guard ring in Variant 2. I can create both KiCad 7/8 projects, generate validated Gerber and Excellon files, and prepare the manufacturing order for JLCPCB or PCBWay. I can also confirm the total cost before ordering and request the nominal solder-mask thickness from the manufacturer. Just send me a message and we can get started. Best regards, Samuel Tshibangu

Hi. Solder mask thickness 15 micron over copper and 30 micron between copper traces at jlc. I have a question, the via on active pad will leave a hole at ground pad on bottom. Is that intentional? PCB cost at jlc for both boards will be 7$ without shipping and taxes. Rest is simple. Thanks

Hi, I am a Senior PCB Design Engineer with 10+ years of experience in mixed-signal, sensor, and industrial PCB development, having completed 200+ PCB layouts including capacitive sensors, IoT devices, and production-ready 2-8 layer boards using KiCad and Altium. I understand this is a functional electrode PCB where solder mask thickness, copper isolation, and dielectric behavior are critical, and I will strictly follow the specified geometry without applying standard exposed-copper PCB practices. Approach: ✅ I will create the KiCad 7/8 project with two independent 100×100mm PCB variants, defining precise copper zones, isolated nets, central ACT via placement, and required backside pads/silkscreen. ✅ I will verify front solder mask coverage, electrical isolation between ACTIVE, GUARD, and SHIELD nets, and generate manufacturing-ready Gerber and Excellon files. ✅ I will prepare the JLCPCB/PCBWay order configuration, confirm fabrication parameters including solder mask thickness availability, and provide order tracking details after approval. Questions: ✅ Can you confirm whether the active electrode should use the standard JLCPCB solder mask thickness value or if a specific dielectric thickness target is preferred for capacitance calibration? ✅ For Variant 2, I will leave the GRD pad omitted unless you prefer keeping an unconnected test pad for future measurements — please confirm your preference. Best, Yaroslav

@edi45

--MANUFACTURING FEE INCLUDED-- Hi, are you trying to build somekind of capacitive sensor? the solder mask thickness state by JLCPCB is >= 10um, i think if you range within 15-40um will be acceptable. i can build you this PCB quickly and i order many time from JLCPCB, for 5pcs 100x100mm may only takes less than 10USD. the shipping cost may be higher, but i think i can order you on your behalf. and i can ship you this 2 variant (100x100mm) from JLC with no additional charge so you don't have to pay anything anymore. just let me know, i have 11 years of experience in PCB design across multiple application from medical instrument to industrial refinery
