BackBoard, cross at 90° to minimize capacitance between traces - .3mm for non-power lines, .6mm if carrying power - MK uses a ground plane on only one side to a trace already - use spokes where ground planes are copper fill applied everywhere there isn't a trace already - use spokes where ground planes connect to the integrator Op-Amp (U3-10). Cut the current Fireball design, some pots are about 21mm apart, meaning that knobs shouldn't be so hard. - In general, try to avoid multiple triggers on each - Could make the hole for mounting screw: ISO 1481-ST 2.2x6.5 C or ISO 7049-ST 2.2x4.5 C or ISO 7049-ST 2.2x6.5 C (http://www.fasteners.eu/standards/ISO/7049/) || order number: 1755626 12A Generic Phoenix Contact connector footprint for: MCV_1,5/12-GF-5.08; number of pins: 07; pin pitch: 3.50mm; Vertical || order number: 1830703 8A 160V Generic Phoenix Contact connector footprint for: MSTBV_2,5/3-GF; number of pins: 10; pin pitch: 5.08mm; Angled; threaded flange || order number: 1776508 12A || order number: 1766288 12A 630V Generic Phoenix Contact connector footprint for: GMSTBVA_2,5/10-G; number of pins: 10; pin pitch: 3.50mm; Vertical; threaded flange || order number: 1806287 12A 630V Generic Phoenix Contact connector footprint for: MSTBV_2,5/5-GF; number of pins: 04; pin pitch: 5.08mm; Angled || order number: 1923869 16A (HC Generic Phoenix Contact SPT 2.5/11-H-5.0 Terminal Block, 1732496 (https://www.phoenixcontact.com/online/portal/gb/?uri=pxc-oc-itemdetail:pid=1732496), generated with kicad-footprint-generator Tantalum Capacitor SMD 0504 (1310 Metric), square (rectangular) end terminal, IPC_7351 nominal, (Body size from: http://www.kemet.com/Lists/ProductCatalog/Attachments/253/KEM_TC101_STD.pdf), generated with kicad-footprint-generator ipc_gullwing_generator.py TSSOP, 40 Pin (https://www.jedec.org/standards-documents/docs/mo-142-d variation EA), generated with kicad-footprint-generator Molex PicoBlade series connector, BM16B-ZESS-TBT (http://www.jst-mfg.com/product/pdf/eng/eZE.pdf), generated with kicad-footprint-generator ipc_noLead_generator.py QFN, 68 Pin (https://cdn.microsemi.com/documents/1bf6886f-5919-4508-a50b-b1dbf3fdf0f4/download/#page=98), generated with kicad-footprint-generator JST XA series connector, 505405-1570 (http://www.molex.com/pdm_docs/sd/5054050270_sd.pdf), generated with kicad-footprint-generator Molex Nano-Fit Power Connectors, old mpn/engineering number: 5566-18A2, example for new part number: 26-60-5060, 6 Pins per row (https://www.hirose.com/product/document?clcode=CL0537-0834-6-81&productname=DF12E(3.0)-50DP-0.5V(81)&series=DF12&documenttype=2DDrawing⟨=en&documentid=0000992393), generated with kicad-footprint-generator Diode SMD 0201 (0603 Metric), square (rectangular) end terminal, IPC_7351 nominal, (Body size source: IPC-SM-782 page 72, https://www.pcb-3d.com/wordpress/wp-content/uploads/ipc-sm-782a_amendment_1_and_2.pdf), generated with kicad-footprint-generator JST XH series connector, SM03B-SRSS-TB (http://www.jst-mfg.com/product/pdf/eng/eSH.pdf), generated with kicad-footprint-generator Molex Molex 1.00mm Pitch Easy-On BackFlip, Right-Angle, Bottom Contact Style, 15 Circuits (https://www.molex.com/pdm_docs/sd/2005280150_sd.pdf), generated with kicad-footprint-generator JST VH PBT series connector, LY20-42P-DT1, 21 Circuits (http://www.jae.com/z-en/pdf_download_exec.cfm?param=SJ103130.pdf), generated with kicad-footprint-generator connector.
