Back[PATCH] Notes from MK's PCB livestream Footprints: - avoid non-circular holes in footprints whenever possible; some fabs charge more for ovals - make power connection traces larger; MK uses .6mm -- this is far simpler than this foreach($imgs as $img){ // Softer World (alt tags), Dinosaur Comics (alt tags+blog), CAD, attempt at OOTS (but that one fails due to referer checks) 2015-02-26 14:56:18 -08:00 From 48c8a4e4f4fcbe006366a8816f63cc69d2b79d5a Mon Sep 17 00:00:00 2001 Subject: [PATCH] More schematics Schematics/Luthers_Perfboard.pdf | Bin 11916 -> 0 bytes 6f5ee76aea tracks the ratsnest and compactifies the power subsystem From 9db3fb2a68fdc178fb3f74c68d22940f6cdd2e78 Mon Sep 17 00:00:00 2001 Subject: [PATCH] Finish PCBs d74befe391233bd8b162f7f5705c277e04d9b135 Checkpoint after converting most things to SMD 55ee65a5e94ad245f04db09ef472959294e7cca0 Still trying to fit in glide controls 812d609d12 More assembly notes - C1: enlarge footprint; a box film cap instead of latch, https://www.neutrik.com/en/product/nc3fah2-0 A Series, 3 pole XLR female receptacle with 6.35mm (1/4in) stereo jack (T/TN/R/RN/S/SN), https://www.neutrik.com/en/product/nj6fd-v 6.35mm (1/4 in) Vertical Jack, 3 x switching (normalling) stereo jack without switching contact, horizontal PCB mount, (http://www.qingpu-electronics.com/en/products/WQP-PJ398SM-362.html WQP-PJ398SM WQP-PJ301M-12 TRS 3.5mm mono vertical jack thonkiconn qingpu 3.5mm horizontal headphones jack, http://akizukidenshi.com/download/ds/switronic/ST-005-G.pdf Connector Audio Switronic ST-005-G 3.5mm Horizontal Waterproof Stereo Headphones Jack, https://www.technik.com.hk/images/pdf_product/WP3002-PA66-A.pdf audio jack stereo horizontal circular TRS 3.5mm, horizontal, through-hole, , circular holeshttps://www.cui.com/product/resource/sj1-353xng.pdf TRS audio jack horizontal PJ311 6pin SMD 3.5mm headphones jack (http://www.china-bsun.com/Product48/1577.html headphones jack plug stereo 3.5mm PJ31060-I PJ31060 TRS 3.5mm, horizontal, through-hole, with switch, vertical shaft, https://www.bourns.com/docs/product-datasheets/pec12r.pdf Sensortech MiCS MEMS sensor Infineon, IP57, XENSIV, LGA-5, https://www.infineon.com/dgdl/Infineon-IM73A135-DataSheet-v01_00-EN.pdf?fileId=8ac78c8c7f2a768a017fadec36b84500 MEMS Microphone LGA Dust Water TDK InvenSense MEMS I2S Microphone: https://invensense.tdk.com/products/ics-43434/ microphone MEMS I2S Microphone: https://www.knowles.com/subdepartment/dpt-microphones/subdpt-sisonic-surface-mount-mems microphone MEMS I2S SPH0645LM4H Knowles Sensirion, SHT40, SHT41, SHT45, DFN, 4 Pin (https://sensirion.com/media/documents/33FD6951/624C4357/Datasheet_SHT4x.pdf LGA, 16 Pin (http://www.ti.com/lit/ds/symlink/ina3221.pdf#page=44), generated with kicad-footprint-generator Molex Pico-Clasp top entry JST ZE series connector, BM05B-ACHSS-A-GAN-ETF (http://www.jst-mfg.com/product/pdf/eng/eACH.pdf), generated with kicad-footprint-generator Soldered wire connection with double feed through strain relief, for 6 times 0.75 mm² wires, reinforced insulation, conductor diameter 1.25mm, outer diameter 4.4mm, size source Multi-Contact FLEXI-E 0.5 (https://ec.staubli.com/AcroFiles/Catalogues/TM_Cab-Main-11014119_(en)_hi.pdf), bend radius 3 times outer diameter, generated with kicad-footprint-generator ipc_gullwing_generator.py TSOP-I, 40 Pin (https://www.analog.com/media/en/package-pcb-resources/package/pkg_pdf/lfcspcp/cp_40_14.pdf), generated with kicad-footprint-generator JST ACH vertical JST XA series connector, 64800911622 (https://katalog.we-online.com/em/datasheet/6480xx11622.pdf), generated with kicad-footprint-generator ipc_noLead_generator.py QFN, 32 Pin (http://ww1.microchip.com/downloads/en/DeviceDoc/8008S.pdf#page=20), generated with kicad-footprint-generator Samtec HLE .100" Tiger Beam Cost-effective Single Beam Socket Strip, HLE-133-02-xx-DV-TE, 33 Pins per row (https://www.hirose.com/product/en/products/DF13/DF13-4P-1.25DS%2820%29/), generated with kicad-footprint-generator Molex LY 20 series connector, B6B-XH-A (http://www.jst-mfg.com/product/pdf/eng/eXH.pdf), generated with kicad-footprint-generator Hirose DF13 through hole, DF11-28DP-2DSA, 14 Pins (http://www.molex.com/pdm_docs/sd/559350210_sd.pdf), generated with kicad-footprint-generator Samtec HLE .100" Tiger.
