Nov yog txoj hauv kev yooj yim los tsim koj tus kheej PCBs hauv tsev. Txoj hauv kev yog ua raws txheej txheem "5 Bears" (uas yog nws tus kheej raws li Tom Gootee tus txheej txheem). Kuv tau ntxiv ob peb qhov kev hloov kho.

Kauj Ruam 1: Tsim Koj Tus Tsim

Pib tawm los ntawm kev teeb tawm PCB cov ntawv cim & ntaub qhwv nrog koj nyiam CAD lossis PCB tsim qauv. Kuv siv Pad2Pad, feem ntau vim tias kuv pom qhov program zoo nkauj siv yooj yim, thiab nws yog dawb rau rub tawm. Koj yuav tsum siv Pad2Pad los tsim lub rooj tsavxwm, tom qab ntawd xa cov ntawv mus rau lub tuam txhab tsim khoom. Hloov chaw, Kuv siv qhov kev tsim no los tsim kuv tus kheej daim npog ntsej muag. Hmoov tsis zoo, koj tsis tuaj yeem xa cov ntaub ntawv p2p rau lwm hom ntawv. Yog li, kuv tau luam tawm pawg thawj coj saib ua PDF, tom qab ntawd qhib lub PDF rau hauv Illustrator, uas tso cai rau kuv los ntxuav & kho lub suab kom raug thiab cais nws ua cov txheej. Cov txheej txheem no yog tsim kom muaj ib sab ib sab PCBs, yog li kuv tau ua ob daim npog qhov ncauj: Ib qho rau cov tooj liab thiab cov ntaub qhwv, lwm qhov rau daim iav. Koj yuav tsum luam tawm daim iav daim duab ntawm koj lub qhov ncauj qhov ntswg - koj yuav pom yog vim li cas sai sai no - tab sis vim tias cov kab cim mus rau tom qab ntawm lub rooj tsavxwm, koj tuaj yeem luam tawm cov ntawv ib txwm muaj. Daim npog qhov ncauj yuav tsum tau luam tawm rov qab. Kuv siv 2pt kab rau feem ntau ntawm cov cim; uas tawm los txog li 0.028 ".

Kauj Ruam 2: Luam daim npog qhov ncauj

Qhov no yog cov kauj ruam Koj yuav tsum luam tawm lub qhov ncauj qhov ntswg mus rau ntawv tshwj xeeb, thiab ua rau lawv tsaus li qhov ua tau. Nov yog qhov kuv tau ua. Kuv siv Jet Print Multi-Project cov ntawv ci ci. Kuv yuav tsum xaj nws online, tab sis nws yuav muaj nyob ntawm cov khw muag khoom hauv chaw ua haujlwm loj. Tom Gootee pom zoo Staples "Daim Duab Duab"; uas zoo li yooj yim kom tau txais. Hmoov tsis zoo kuv tsis tau nyeem Gootee kab lus kom txog tom qab kuv twb tau txais Jet Luam ntawv lawm. Yog li ntawv Staples tej zaum yuav zoo dua.

Cov ntawv no tau muag raws li cov ntawv number case-jet. Tab sis rau cov txheej txheem no, koj yuav tsum tau khiav lawv los ntawm lub tshuab luam ntawv laser. Toner tsim lub npog ntsej muag. Thiab, koj xav kom lub toner ua kom tsaus thiab tuab raws li qhov ua tau. Kuv pom tias yog tias koj qhia lub tshuab luam ntawv tias koj tab tom luam tawm lub pob tshab, nws yuav siv ntau lub toner. Kuv kuj hloov kho ntau yam teeb tsa ntawm lub tshuab luam ntawv cov ntawv (piv txwv li, lub tshuab luam ntawv ceev, kev ua kom zoo, thiab lwm yam) kom tau txais qhov tuab tshaj plaws luam tau - koj lub tshuab luam ntawv teeb tsa yuav txawv. Sim ua kom pom qhov ua haujlwm zoo tshaj plaws, thiab sau ntawv thaum koj mus yog li koj yuav muaj peev xwm theej koj cov kev ua tau zoo tshaj plaws tom qab. Kuv hlawv los ntawm cov ntawv me me ua ntej kuv tau txais nws raug, tab sis tam sim no kuv tau txais nws yog thawj zaug. Yog tias koj tus PCB tsim muaj cov kab ntsug ntev, koj tuaj yeem taw qhia tus qauv tsim ntawm nplooj ntawv kom cov kab ntawv ntev yog kaum. Vim yog qhov kev taw qhia uas cov ntawv hla los ntawm cov tshuab luam ntawv laser, cov kab ntsug ntev yuav poob qhov toner ntom ze rau hauv qab. Angling cov cim ntev yuav pab khaws lub toner ntom ntawm qhov ntev tag nrho. Nco ntsoov luam daim npog tooj liab "txoj cai nyeem"-piv txwv li TSIS YOG daim iav-tab sis daim npog "silkscreen" yuav tsum luam tawm rov qab. Ua ib daim ntawv lossis ob daim thiab nrhiav daim npog ntsej muag uas tsis sib xws nrog qhov tsawg kawg ntawm qhov pinholes. Ua kom ntseeg tau tias tag nrho cov kab thiab cov ntaub qhwv tau ua tiav.

Kauj Ruam 3: Npaj Blank Board

Txiav koj lub rooj tsavxwm kom loj, tawm hauv chav me me nyob ib ncig ntawm cov npoo. Kuv siv lub hacksaw, uas tawm qee qhov burrs. Ua ib qho burrs tawm nrog dremel lossis cov ntawv me me. Koj xav kom cov tooj liab ua kom tiaj li sai tau. Xuab zeb saum npoo av ntawm daim ntawv dawb paug nrog 400-600 cov xuab zeb xuab zeb hauv ob kab lus qhia hauv kab lus hla. Tom qab ntawd, siv acetone ntawm daim ntawv so tes los ntxuav lub rooj kom huv si kom ntau li ntau tau. Roj me ntsis yog koj tus yeeb ncuab! Txhuam lub rooj tsavxwm zoo heev.

Kauj Ruam 4: Txuas daim npog ntsej muag rau ntawm Pawg Thawj Coj

Ua tib zoo txiav daim npog rau sab tooj liab los ntawm koj daim ntawv luam tawm. Tso nws lub ntsej muag-down rau ntawm koj lub rooj tsavxwm, kom lub toner ntsib lub tooj liab. Kuv siv cov ntawv me me ntawm kab xev ntawm txhua ntug los tuav lub npog ntsej muag nyob hauv qhov chaw. Qhov ntawd yuav tsis tsim nyog yog tias koj qhov dawb paug loj dua koj daim npog. Kuv pom tias daim npog ntsej muag zoo li yuav xaub yog tias nws tsis muaj daim kab xev ruaj ntseg; koj xav kom zam qhov ntawd thaum ua haujlwm nrog kev zam nruj.

Kauj ruam 5: Hlau

Qhov no yog cov kauj ruam nyuaj tshaj plaws. Koj yuav tsum teeb koj cov hlau rau nws qhov chaw siab tshaj, tsis muaj pa taws. Muab daim ntawv phuam hla lub rooj tsavxwm & daim npog qhov ncauj; txwv tsis pub, cov nplaum yas yaj uas tawm los ntawm hauv qab ntawm daim npog ntsej muag yuav ua rau txhua yam ua rau koj cov hlau.

Thaum xub thawj thov cov hlau, nias ncaj thiab tsis txhob qoj ib ce lossis xaub lub npog ntsej muag. Cov yas txheej txheej ntawm daim ntawv yuav yaj tam sim, tsim ua ntu ntu ntu ib ntus, uas yuav zoo li swb ib ncig yog tias koj tsis xyuam xim. Nov yog qhov uas nws yooj yim tshaj plaws los ntsaws, kuv xav. Pib los ntawm kev thov khov kho, ruaj siab rau tag nrho pawg thawj coj rau ib feeb, txav cov hlau qee zaus kom ntseeg tau tias tag nrho lub rooj tsavxwm tau ua kom sov zoo. Tom qab ntawd, daim npog ntsej muag zoo nkauj heev rau ntawm lub rooj tsavxwm, yog li tam sim no koj tuaj yeem hla tag nrho lub rooj tsavxwm nrog ntug ntawm cov hlau, me ntsis ib zaug. Kuv siv ntug ntawm cov hlau & ntsaws rau nws qee qhov, muab qhov hnyav hnyav siab ntev raws lub rooj tsavxwm. Tom qab ntawd kuv txav cov hlau ib nti peb lub hlis lossis ntau dua thiab rov ua dua kom txog thaum tag nrho pawg thawj coj tau npog. Tom qab ntawd kuv ua tib txoj kab ntawm "kab siab" dav dav thoob plaws lub rooj tsavxwm. Thaum kawg, Kuv ua tiav nrog qhov siab tag nrho rau ob peb feeb ntxiv. Tag nrho lub sijhawm ironing yog tej zaum 3 feeb, saum.

Kauj Ruam 6: So Tawm Daim Ntawv

Muab lub lauj kaub kub tso rau hauv lub lauj kaub dej kub, nrog rau ib daim phuam ntawv uas tuaj yeem txuas nrog. Qee cov ntawv yuav pib tawm tam sim. Pab nws nrog! Tom qab ob peb feeb, ntau daim ntawv tuaj yeem rub tawm. Kuj tev tawm ib daim kab xev uas koj tau siv los tuav lub npog ntsej muag rau ntawm lub rooj tsavxwm. Tom qab 10-20 feeb, koj yuav nqis mus rau txheej kawg, uas zoo li yas dua li ntawv. Cov cim yuav pom meej txawm tias nws. Tau txais lub ces kaum pib, thiab cov yas yuav tsum tev tawm yooj yim, tawm hauv koj nrog daim npog ntsej muag zoo. Yog tias koj tau ironed zoo txaus, lub toner yuav raug fused rau hauv pawg thawj coj; nws tsis tuaj yeem muab tshem tawm nrog cov rau tes.

Yog tias cov kab me me tau ua rau txhua txoj hauv kev - piv txwv li, yog tias cov hlau ntog - koj tuaj yeem tshem tawm cov toner fused nrog acetone thiab pib dua nrog daim npog tshiab.

Kauj ruam 7: Etch

Muab lub rooj tsavxwm tso rau hauv koj qhov kev daws teeb meem. Tsis txhob cia cov tshuaj lom nkag mus rau txhua yam uas ua los ntawm hlau! Kuv siv lub ntim yas loj. Lwv lub rooj tsavxwm kom txog thaum tooj liab uas ploj lawm. Nyob ntawm seb qhov tshiab & sov cov tshuaj lom li cas, nws tuaj yeem siv sijhawm 10-30 feeb.

Kauj Ruam 8: Ntxuav Daim npog qhov ncauj

Siv acetone los ntxuav lub toner. Koj yuav tau sab laug nrog lub vaj huam sib luag ci ci zoo nkauj!

Kauj Ruam 9: Siv Silkscreen Layer

Tam sim no nws yog lub sijhawm ntxiv "silkscreen" mus rau lwm sab ntawm pawg thawj coj saib. Nws tsis yog tiag tiag silkscreen; nws yog qhov txheej txheem tib yam li tau piav qhia saum toj no, tshwj tsis yog tias koj tso lub fused toner rau ntawm lub rooj tsavxwm thiab tsis txhob ua cov etch thiab ntxuav tawm.

Txhawm rau ua kom "txhob lo lo ntxhuav", Kuv laum lub qhov nyob hauv plaub daim ntaub qhwv pob kws. Tom qab txiav daim npog lo lo lo ntxhuav, kuv tso nws toner-sab-down tawm tsam sab ntawm lub rooj tsavxwm yam tsis zoo ib yam. Tuav nws mus rau lub teeb, koj yuav tsum muaj peev xwm pom plaub lub kaum qhov los ntawm daim npog qhov ncauj. Siv cov no los ua kab ntawm daim npog ntsej muag kom raug, tom qab ntawd kaw nws mus rau lub rooj tsavxwm nrog daim kab xev. Tom ntej no, hlau lub rooj tsavxwm tib yam koj tau ua rau sab tooj, thiab thaum kawg tsau cov ntawv zoo li hauv qib 6.

Kauj Ruam 10: Laum Lub Qhov

Nov yog qhov nyuaj me ntsis, tab sis tuaj yeem ua tiav yam tsis tas yuav siv lub laum xovxwm lossis lwm yam cuab yeej zoo nkauj. Kuv siv lub cuab yeej dremel nrog #60 ntsis. Qhov ntawd yog qhov tsawg tshaj plaws kuv tuaj yeem pom ntawm lub khw muag khoom kho vajtse hauv ib cheeb tsam. Qhov me ntsis yog clamped rau hauv lub collet, uas nyob rau hauv lem yog tuav hauv dremel's chuck.

Nov yog kuv li kev zais ntau qhov me me nrog qhov tuav tes: siv cov khoom seem ntawm acrylic ua cov ntawv qhia laum. Laum ib lub qhov hauv acrylic, tom qab ntawd dhau los ntawm lub qhov thiab hla lub rooj tsavxwm. Cov acrylic ntshiab ua rau nws yooj yim rau kab kab me ntsis kom raug ntawm qhov nruab nrab ntawm txhua lub ncoo. Tom qab kaum lub qhov los yog li ntawd, "qhia qhov" hauv cov acrylic yuav pib "xoob tawm" - tsuas yog laum lwm qhov qhia & ua mus ntxiv.

Kauj ruam 11: Ua tiav

Pawg thawj coj tau npaj siv.

Kuv tau ua plaub pawg siv txoj hauv kev no. Thawj qhov yog qhov zoo tshaj plaws, tab sis tau tawg los ntawm qhov tsis zoo. Qhov thib ob thiab thib plaub kuj zoo tag nrho & ua haujlwm tau zoo hauv cov phiaj xwm. Ntawm lub rooj tsavxwm thib peb, kuv tau txav cov hlau thaum kuv xub thov nws, yog li daim npog tau plam thiab qhov muag tsis pom. Nrog kev xyaum me ntsis, koj tuaj yeem ua lub rooj tsavxwm hauv ob peb teev (tsis suav nrog lub sijhawm tsim).
