Txhawm rau tsim cov ntiv tes cuav, koj xav tau cov ntiv tes tiag. Hauv tsev, koj tuaj yeem ua cov txheej txheem no pib los ntawm nias ib tus ntiv tes mus rau hauv ib lub pob ntawm putty. Cov ntiv tes nyob qis qis, uas yog cov roj pom tsis pom los ntawm koj cov ntiv tes, tseem tuaj yeem siv los tsim cov ntiv tes cuav, tab sis nws yuav siv qee qhov ua siab ntev los teeb tsa qee yam cuab yeej thiab ua cov kauj ruam.

Kauj Ruam 1. Ua tus ntiv tes ntawm cov khoom xws li muab tshuaj txhuam

Putty, "Play-doh" (hom xim av nplaum rau cov menyuam yaus cov khoom ua si), lossis ua qauv av nplaum zoo, tsuav yog lawv tshiab thiab huv. Hloov cov khoom siv uas koj tau xaiv ua ntej mus rau hauv lub pob, tom qab ntawv nias tus ntiv tes uas koj yuav ntiv tes rau ntawm lub npas.

Siv kub, ua kom cov plaub hau sib xyaw ua kom sov zoo yuav muab cov txiaj ntsig zoo dua, tsuav yog koj ua siab ntev tuav koj tus ntiv tes rau tsib rau kaum feeb ntawm qhov chaw

Kauj Ruam 2. Muab cov tshuaj tso rau hauv lub tub yees lossis lub tub yees kom khov nws

Lub hom phiaj yog ua kom cov ntiv tes luam tawm nyuaj li sai tau. Txhua cov khoom siv thiab cov npe yuav hnov txawv txawv rau qhov txias txias, yog li nws muaj peev xwm tias cov tshuaj txhuam no yuav tsis rov siv tau rau tom qab tom qab, tab sis nws muaj txiaj ntsig zoo li cov khoom siv luam tawm rau cov ntiv tes.

Kauj Ruam 3. Ua tuab tuab heev

Boil ib lub lauj kaub me me ntawm cov dej, tom qab ntawd maj mam ntxiv cov gelatin hmoov kom txog thaum sib npaug. Khaws rau ob peb feeb kom txog thaum cov hmoov yaj tag. Txias lub mov paj.

Kauj Ruam 4. Muab cov gelatin tso rau hauv lub microwave

Thaum cov gelatin tau txias thiab tuab, yaj nws hauv lub microwave, tom qab ntawd tso rau hauv tub yees. Rov ua cov txheej txheem no kom txog thaum kev ntxhib los mos yog tuab thiab ywj, thiab tsis muaj npuas ntau hauv gelatin.

Kauj Ruam 5. Ncuav cov gelatin rau ntawm cov ntiv tes

Thaum cov gelatin tau ywj pheej thiab tsis muaj npuas, yaj nws ib zaug zaum kawg, tom qab ntawd ncuav cov kua gelatin kub rau hauv cov kua rau koj cov ntiv tes sau.

Kauj Ruam 6. Khov

Muab cov pwm tso rau hauv uas twb muaj cov gelatin tso rau hauv lub tub yees. Hauv ob peb feeb, gelatin yuav tawv rau hauv cov khoom ua kom khov thiab khov. Ua tib zoo tshem tawm cov gelatin los ntawm cov pwm tso. Ua tus ntiv tes tsis tseeb nrog cov ntiv tes tiag tiag ntawm nws qhov chaw.

Txoj Kev 2 ntawm 2: Siv Cov Txheej Txheem Zoo

Kauj Ruam 1. Nyeem tag nrho cov kauj ruam ua ntej sim nws

Nrog rau cov txheej txheem no, cov ntiv tes tuaj yeem ua tau zoo dua yam tsis tas yuav tsum luam tawm cov ntiv tes ntawm cov tshuaj, tab sis koj yuav xav tau cov cuab yeej tshwj xeeb. Tsis txhob sim nws tshwj tsis yog tias koj muaj cov cuab yeej hauv qab no, suav nrog lub koob yees duab zoo lossis lub tshuab luam ntawv, thiab cov ntawv luam tawm Circuit Board (PCB). Hloov chaw ntawm PCB, koj tuaj yeem siv OHP yas pob tshab, tab sis qhov txiaj ntsig yuav tsis zoo dua.

Kauj Ruam 2. Siv hmoov txhawm rau txheeb xyuas cov ntiv tes

Txoj hauv kev no, koj tuaj yeem tsim cov ntiv tes cuav tsuas yog siv cov ntiv tes tso rau ntawm lub vijtsam kov, lub qhov rooj, lossis lwm yam qhuav, ci ntsa iab. Txhawm rau txheeb xyuas cov ntiv tes, koj tuaj yeem nchuav cov nplaim nrog cov hmoov zeb los ntawm cov av nplaum ua kom zoo, lossis cov hmoov dub tshwj xeeb rau taug qab cov ntiv tes.

Ua tau zoo tshaj plaws ntawm cov xim dawb

Kauj Ruam 3. Nqa tus ntiv tes nrog lub tshuab scanner lossis lub koob yees duab siab

Rau qhov ua tau zoo tshaj plaws, luam theej duab lossis thaij duab nrog daws teeb meem tsawg kawg 2400 dpi. Thauj cov duab rau hauv cov txheej txheem khoos phis tawj nrog kho duab software.

Kauj Ruam 4. Rov qab cov lus qhia thiab xim ntawm daim duab

Siv cov software kho duab kom "ntxeev" cov duab sab laug-rau-sab xis, dhau los ua daim iav. Kuj tseem thim xim ntawm daim duab, yog li cov ntiv tes uas tshwm yog dawb, thiab keeb kwm yav dhau yog dub.

Kauj Ruam 5. Hloov daim duab mus rau PCB lossis OHP

Kom tau txais txiaj ntsig zoo tshaj plaws, luam cov ntiv tes duab ntawm kab ntawv, tom qab ntawd siv lub tshuab UV tshem tawm kom hloov cov ntiv tes mus rau PCB. Yog tias koj tsis muaj cov cuab yeej thiab cov khoom siv no, koj tuaj yeem luam tawm ncaj qha rau ntawm OHP yas, txawm tias cov txiaj ntsig tau tsawg dua li zoo meej.

Kauj Ruam 6. Tsim cov ntiv tes cuav nrog granite thiab ntoo nplaum

Cov ntiv tes duab ntawm PCB lossis OHP yas yog qhov tseeb me ntsis embossed, yog li nws tuaj yeem siv los ua cov lus qhia ntiv tes cuav. Ua ntej, npog daim duab nrog cov hmoov zeb, tom qab txhuam sab saum toj nrog txheej nyias ntawm cov kua ntoo dawb lossis cov kua nplaum ua kua nplaum.

Me ntsis glycerol hauv cov kua nplaum ntoo yuav ua rau nws ntub me ntsis thiab ua haujlwm tau zoo

Kauj Ruam 7. Tshem tawm cov ntiv tes dag los ntawm cov kua nplaum qhuav

Tom qab cov kua nplaum ua kom qhuav, ua tib zoo tev nws tawm ntawm PCB sab saum toj, yog li nws dhau los ua cov tuabneeg dag. Koj tseem tuaj yeem txiav me ntsis kom huv si, tom qab ntawd muab lo rau ntawm koj lub ntsis ntiv tes nrog cov kua nplaum los yog lwm cov tawv nqaij ruaj ntseg.
