Txoj hauv kev no tso cai rau kev tsim cov PCBs zoo ib yam thiab zoo hauv tsev nrog ob peb yam khoom siv sib xws thiab nyob rau lub sijhawm luv luv. Nrog txhua cov ntaub ntawv npaj txhij, tag nrho cov txheej txheem tuaj yeem ua tiav hauv ob peb teev.

Cov ntsiab lus ntawm phau ntawv qhia, me meDice:

Rau lub hom phiaj ntawm phau ntawv qhia no, cov txheej txheem yuav piav qhia nrog kev tsim khoom ntawm 3 pawg me me, ib qho hluav taws xob tuag raws li atTiny85 microcontroller nrog software charlieplexing, uas tso cai tswj ntawm 9 LEDs nrog tsuas yog 4 tus pin thiab 4 tus tiv thaiv. Nws yog qhov hloov kho tshiab ntawm kuv li qub me meDice (2014), thiab txhua qhov ntaub ntawv qhov xav tau rau qhov Kev Qhia Qhia no muaj rau rub tawm raws li cov ntawv ntim ntawm cov khoom siv kauj ruam.

Keeb kwm ntawm txoj kev:

Raws li cov neeg siv khoom siv hluav taws xob, Kuv tau muaj kuv qhov kev qhia ncaj ncees ntawm kev ua PCBs yav dhau los, tab sis feem ntau txoj hauv kev hauv tsev yog qhov tsis txaus ntseeg, zoo li Toner hloov txoj hauv kev, lossis ntau dhau nyuaj thiab ua haujlwm hnyav, zoo li CNC router txoj kev lossis UV txoj kev photoresist (uas kuv tau npog yav dhau los ntawm thawj qhov me me Dice). Ib qho ntxiv, qhov kawg ntawm cov khoom lag luam zoo li tsis zoo, tshwj xeeb tshaj yog tias koj sim ua kom siv UV muag khoom muag.

Los ntawm cov kev paub tsis txaus siab no, Kuv txiav txim siab tshawb nrhiav lwm txoj hauv kev los tsim PCBs hauv tsev. Raws li kuv nyuam qhuav pib sim nrog lub tshuab yas yas txiav, nws tshwm sim rau kuv tias daim yas yas tuaj yeem ua daim npog zoo tshaj plaws thiab txhim khu kev qha rau PCB etching. Ntawm kev tshawb fawb online thawj zaug, Kuv tsis pom ib tus neeg siv cov vinyl stamp los ua PCBs, uas ua rau kuv xav tsis thoob vim nws zoo li plausible. Qhov no txhawb kuv kom sim nrog cov txheej txheem thiab nrhiav seb nws puas tuaj yeem ua haujlwm tau zoo thiab muaj txiaj ntsig los hloov PCB cov cim ntawm lub khoos phis tawj mus rau tooj liab.

Kev txhim kho cov txheej txheem:

Ua kom huv thiab zoo ib yam cov tooj liab hauv PCB hauv tsev yog qhov ua tiav, tab sis txhawm rau pof cov PCBs kom ua haujlwm tau zoo thiab kav ntev, lawv xav tau qee yam kev ua haujlwm soldermask, uas tiv thaiv cov choj tsis xav tau thiab tiv thaiv cov tooj liab los ntawm kev xeb. Kev lig kev cai, daim npog ntsej muag uas siv tau yog nyob rau hauv daim ntawv ntawm UV kho kab mob, uas hauv kev coj ua yog qhov nyuaj ua haujlwm nrog.

Thaum xub thawj, kuv npaj siab siv vinyl sickers ncaj qha raws li lub npog ntsej muag rau kev kho UV soldermask. Txawm li cas los xij, ntawm ntau qhov kev sim, Kuv tsis tuaj yeem tau txais UV soldermask kom ntseeg tau kho tau ntawm qhov chaw xav tau nkaus xwb, thiab kuv yeej tsis muaj peev xwm ua kom cov tawv nqaij txaus thiab txawm tias txheej, uas thaum kawg ua rau pawg pawg ntoo puas. Yog li kuv tau muab lub tswv yim ntawd tshem tawm thiab nws tshwm sim rau kuv tias tej zaum qee yam ntawm cov thwj cim tseem tuaj yeem siv ua qhov muag muag, txawm hais tias nws yeej tsis yog yas, vim nws yuav tsis cuam tshuam nrog cua sov ntawm reflow soldering.

Nrog rau qhov no kuv tau saib mus rau Kapton daim kab xev, uas yog tus kheej-nplaum, nyias, thiab cog lus tias yuav tiv taus qhov kub txaus txaus rau kev siv tshuaj yaj yeeb. Kapton daim kab xev tau muag hauv yob, tab sis nws tshwm sim rau kuv tias yog tias nws tau thov dua thaub qab ntawm cov yas yas, nws tuaj yeem txiav ncaj qha rau ntawm cov yas txiav thiab siv ncaj qha ua lub thwj cim. Los ntawm thawj qhov sim ntawm qhov no, nws tau pom tseeb tias Kapton daim kab xev coj tau zoo heev ntawm cov yas txiav, txawm hais tias txhua qhov kev txiav uas hla dhau cov npuas me me tau jagged lossis tsis tiav, yog li tus yuam sij kom zoo meej kapton cov nyiaj muas noj tau siv daim kab xev zoo kawg nkaus ntawm yas thaub qab yam tsis tso cai rau huab cua nkag rau hauv qab. Qhov no pib ua pov thawj tsis yooj yim, vim Kapton yog qhov hnyav dhau thiab nplaum, tab sis thaum sim ua kom nws siv daim npav yas txheem kuv pom tau tias nws tuaj yeem ua tiav thiab yooj yim hauv txoj kev no.

Los ntawm cov kev sim no rov ua haujlwm kuv kuj tau pom qee qhov kev txwv tsis pub siv ntawm cov txheej txheem, uas xa nyiaj tuaj yeem ua nrog daim npog tooj liab thaum xub thawj. Cov kev txwv no hloov pauv mus rau txheej txheej txheej txheem tsim los ua qhov txheej txheem no ntseeg tau.
