Cov lus qhia no qhia yuav ua li cas thiaj ua cov tshuaj txhuam cov nplaum rau cov ntim qis lossis cov qauv txheej saum npoo PCBs siv lub tshuab txiav laser. Nws tau sim nrog Epilog thiab CCL (pheej yig suav suav sau xws li JSM 40) thiab yuav tsum ua haujlwm yuav luag txhua hom laser txiav uas tuaj yeem siv hom raster thiab muaj lub zog txaus los txiav ntawv.

Spoiler ceeb toom: Cov kua ntses zais cia ntawm cov lus qhia no yog txiav cov hinges nyob rau hauv lub stencil kom cov stencil tus kheej haum nrog PCB.

Thawj kauj ruam yog kom muaj PCB tsim. Kev tsim PCB tiag yog dhau qhov uas tau qhia tseg no. Hauv cov duab piv txwv PCB tau tsim hauv Eagle, ib pob software uas ib txwm muaj.

Kauj Ruam 1: Tua Txheej

Txhawm rau tsim cov duab stencil huv, tua txhua txheej tshwj tsis yog muab tshuaj txhuam thiab qhov ntev. Nco ntsoov tias cov kab dav dav muaj qee qhov dav (qee cov txheej txheem txheej txheej PCB muab cov kab dav dav xoom dav; kos "kab", "khoom"). Yog tias cov kab muaj xoom dav, kho lawv.

Ua kom ntseeg tau tias cov khaubncaws sab nraud povtseg pom tau tias yog xim xim, tsis txhob hla lub qhov.

Muab tshuaj txhuam yog thaj chaw uas koj xav npog hauv cov tshuaj txhuam hniav.

Qhov ntev yog tus qauv ntawm PCB, uas feem ntau suav nrog qhov.

Qhib cov duab hauv cov duab ua haujlwm xws li GIMP (rub tawm dawb), uas tau siv hauv qhov piv txwv no.

Autocrop cov duab kom tshem tawm thaj chaw tsis xav tau, daim duab kawg yuav tsum yog PCB nkaus xwb uas tsis muaj kev hloov pauv.

Teeb tus pib thiab txo cov duab kom dub thiab dawb.

Hloov cov xim. (Feem ntau cov tshuab txiav laser tuaj yeem ua qhov no thaum txiav, tab sis kho qhov no yooj yim dua).

Lwv cov mounting qhov. Yog tias lub qhov tso rau hauv qhov chaw, lawv yuav dhau los ua qhov txiav tawm hauv lub stencil thiab sau nrog cov tshuaj txhuam.

!! KEY STEP !! Lwv qhov chaw nruab nrab ntawm PCB cov lus piav qhia. Tawm ntawm cov ces kaum. Cov kauj ruam no tsim cov lus qhia ua ke kom siv tau thaum kis cov tshuaj txhuam. Thaum koj kaw kab ntawv stencil, cov ces kaum txiav yuav ua rau cov ces kaum ntawm PCB.

Laser txiav tshuab nthuav dav … Epilog txiav qhov tseeb rau qhov loj, qhov pub dawb JSM-40 txiav 1% loj … yog li … ntsuas cov duab yog xav tau.

Qhov piv txwv no siv JSM-40, ib qho laser txiav ntau. Lwm lub tshuab txiav laser yuav xav tau teeb tsa xws li txiav thaj chaw hauv RED.

Ntshuam cov duab ua tiav rau hauv "Kos Duab Tshiab" (lossis koj lub tshuab txiav tshuab laser), teeb tsa lub zog kom txaus los txiav ntawv.

Sau hauv hom raster.

Nco tseg: vim li cas raster thiab tsis yog vector? Siv raster vaporizes daim ntawv, txiav cov nplooj tom qab cov duab plaub me me uas zoo li yuav tua hluav taws (cov hluav taws me me) thiab ua rau lub stencil puas.

Txheeb cov stencil los ntawm txheej txheej stencil thiab PCB, txhua daim ntaub yuav tsum pom kom huv los ntawm stencil. Yog tias cov ntaub qhwv thiab stencil tsis ua kab, txheeb xyuas qhov ntsuas. Piv txwv li kuv JSM-40 xav tau qhov ntsuas ntawm 99% txhawm rau ua kom raug.

Cov tuab lossis "hnyav" ntawm daim ntawv txiav txim siab qhov tuab ntawm cov tshuaj txhuam tom qab stenciling. 70# ntawv ua haujlwm zoo rau 1mm suab, 30# rau.5mm, 20# rau me dua. Ob daim duab kawg no qhia pom qhov ua tau zoo ntawm 70# ntawv.
