Tam sim no, PCBs tuaj yeem yuav pheej yig heev los ntawm Tuam Tshoj. Tab sis cia peb hais tias koj xav tau ib qho hauv 24 teev, ua koj tus kheej yog qhov kev xaiv nkaus xwb. Ntxiv mus, nws yog txoj hauv kev nyuaj dua thiab lom zem!

Hauv Cov Lus Qhia no kuv yuav coj koj mus dhau tag nrho cov txheej txheem ntawm kev ua haujlwm ob tog PCB ntawm tus nqi pheej yig CNC zeb, tsis muaj tshuaj lom neeg! PCB nta:

• Ob tog
• Soldermask (txheej ntsuab)
• Silkscreen (ntawv dawb)
• Tooj tooj liab
• Txawm hais tias qhov plating
• Tinned los (yeem)

Nws tau coj kuv ntau qhov kev sim kom tau mus txog qhov no. Tshwj xeeb tshaj yog cov muag khoom thiab silkscreen tau xav tau qee txoj haujlwm kom los ua cov txheej txheem. Cia peb pib!

Kauj ruam 1: Qhov & Cov Cuab Yeej

Cov cuab yeej

• CNC zeb nrog:

  • 3.175 mm collet (zoo li ER11 collets)
  • Z sojntsuam
• Ntsia ntsia hlau (rau kev ua vias)
• Rauj (rau tsoo lub ntsia hlau punch)
• Sandpaper (nplua daim phiaj)
• UV teeb

Ib qho pheej yig CNC muaj peev xwm ua haujlwm tau zoo. Suav chav nyob yog li ntawm 150-300 $.

Qhov

• PCB blanks / tooj liab clad board
• PCB mills: 0.2 hli, 30 ° ntsis
• PCB xyaum: 1 hli thiab 1.5 hli
• PCB mills: 2 hli thiab 3 hli
• PCB rivets: 0.9 hli thiab 1.3 hli txheej sab nraud
• PCB UV kho tau daim npog qhov ncauj (ntsuab)
• Kho cov kua (tipp-ex)
• 3 hli tuab tuab pins
• PCB thiab kev sib dhos tus pin tuav
• Cov kua nplaum ua kua / tshuaj tin daws (xaiv tau)

Txhua qhov tuaj yeem nrhiav pom rau ntawm pheej yig ntawm AliExpress lossis ebay nrog cov npe saum toj no. Cov tshuaj tin daws yuav nyuaj rau nrhiav thiab tuaj yeem kim heev (kwv yees li 50 daus las rau lub raj mis), tab sis yog qhov ua tau zoo tag nrho. Lub yas dhos PCB thiab tus pin tuav tau siv los txhawm rau txhawm rau PCB ntawm lub txaj CNC. Koj tuaj yeem luam lawv los ntawm cov ntawv zip lossis tus tsim thawj, 2 daim ntawv theej ntawm txhua daim ntawv xav tau.

Kauj ruam 2: Software

Dhau li ntawm CNC zeb thiab qee yam cuab yeej, peb tseem yuav xav tau 3 txoj haujlwm los ua peb tus kheej PCB

• PCB tsim software los tsim koj li PCB
• Flatcam los tsim cov cai rau CNC zeb
• Tswmciab los tswj lub CNC zeb

PCB tsim software

Koj tuaj yeem siv ib qho PCB tsim software uas koj xav tau. Cov kev xaiv nrov muaj xws li: Altium tus tsim qauv, Tus tsim hluav taws xob, Dav dawb hau, Kicad,… Kuv yuav xav tias koj paub tsim PCBs thiab xa cov ntaub ntawv gerber. Yog tias koj tsis paub tias cov no yog dab tsi, tsim cov ntaub ntawv gerber rau PCB yog zoo li tsim PDF rau cov ntawv nyeem. Nws yog txheej txheem txheej txheem kom txuag tau qhov tshwj xeeb ntawm koj li PCB. Koj tuaj yeem pom ntau cov kev qhia hauv online rau qhov no.

Flatcam

Flatcam tsis tshua muaj tshwm sim, tab sis siv tau yooj yim heev. Kuv yuav piav qhia txhua kauj ruam hauv kev nthuav dav thiab coj koj mus rau tag nrho cov txheej txheem. Thaum tsis ntseeg, ua tibzoo saib phau ntawv Flatcam zoo heev. Flatcam yuav coj peb cov ntaub ntawv gerber thiab hloov pauv mus rau hauv lub tshuab txav (gcode) los ntawm cov txheej txheem hu ua kev sib cais. Txhawm rau zeb PCB taug qab, peb yuav tsum zom cov kab sib dhos ntawm txoj kab kom cais nws los ntawm cov tooj liab ib puag ncig, yog li lub npe. Flatcam muaj 4 tabs (saib daim duab):

• Qhov project: muab cov ntsiab lus ntawm cov ntaub ntawv koj qhib lossis tsim
• Xaiv: siv los tsim cov ntaub ntawv tshiab
• Kev xaiv: siv los khaws cov chaw teeb tsa ua ntej
• Cov cuab yeej: siv rau ob tog PCBs

Peb pib los ntawm qhib cov ntaub ntawv gerber nrog Cov Ntaub Ntawv> Qhib Gerber thiab nws yuav tshwm nyob hauv qab qhov Project tab. Tam sim no muaj 3 kauj ruam los hloov qhov gerber no mus rau gcode:

1. Tsim cov cuab yeej cais tawm

   • Nyem rau cov ntaub ntawv gerber hauv Project tab kom xaiv nws thiab nyem rau ntawm Xaiv tab
   • Ntawm no peb tuaj yeem nkag mus rau qhov chaw ntawm cov cuab yeej peb yuav siv thiab nyem rau ntawm Generate geometry
   • Rov qab rau hauv Project tab peb pom cov ntawv tshiab nrog _iso hauv qhov txuas ntxiv

2. Tsim cov duab geometry

   • Nyem cov ntawv cais nyob hauv Txoj Haujlwm tab kom xaiv nws thiab nyem rau Xaiv tab
   • Tam sim no peb nkag mus tob ntawm kev txiav thiab nrawm thiab nyem rau Tsim
   • Rov qab rau hauv Txoj Haujlwm tab ib daim ntawv iso_cnc tau tshwm sim

3. Exporting lub gcode

   • Nyem rau cnc cov ntaub ntawv hauv Txoj Haujlwm tab kom xaiv nws thiab nyem rau qhov Xaiv tab
   • Nyem Export gcode thiab khaws cov ntawv nrog.nc cov ntaub ntawv txuas ntxiv

Cov txheej txheem yooj yim no yuav tsum rov ua dua rau txhua txheej ntawm koj li PCB. Cov kev teeb tsa tshwj xeeb yuav suav nrog hauv cov theem tom ntej thiab yuav hais nyob rau hauv cov ntsuas ntsuas. Tus nqi pub yuav nyob ntawm koj lub tshuab tiag. Rau kev siv: kuv CNC muaj 300W ntxaiv.

Tswmciab

Tswmciab yog siv los tswj lub tshuab CNC; lwm qhov kev xaiv nrov yuav yog Chilipepr. Ib qho software yuav ua haujlwm, tsuav nws muaj kev xaiv los ua qhov siab (ntau ntxiv nyob rau tom qab). Yog koj muaj lub tshuab CNC, koj yuav paub ntau yam kev xaiv thiab yuav tswj lub tshuab li cas. Kuv yuav nkag mus rau cov ntsiab lus rau PCB cov kev xaiv tshwj xeeb peb yuav xav tau.

Cia peb pib milling!
