nyob zoo cov menyuam !!, Koj yuav muaj lossis tsis tau paub nrog kev luam koj tus kheej PCB kev cai. Muaj ntau txoj hauv kev los ua raws li txhawm rau ua PCB. Ib txoj hauv kev ib txwm luam tawm Circuit yog siv tus qauv (Circuit) rau ntawm daim phiaj tooj liab thiab kos cov tooj liab uas tsis xav tau. Tab sis yog tias peb tuaj yeem ua tooj liab tooj liab rau peb tus kheej, muaj ntau yam muaj tswv yim uas tuaj yeem ua tau. Yog li hauv cov lus qhia no kuv yuav qhia koj txoj hauv kev uas tuaj yeem siv los ua PCB kev cai ntawm ib qho twg uas tsim nyog. Txhua qhov chaw xav kom ua tau qhov no. Txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txheej txheej tooj liab yuav tsum ua kom sov siab dua ib puag ncig 270 degrees Celsius. Cov ntaub ntawv xws li yas tsis ua rau nws. Rau qhov ua piv txwv no kuv xaiv iav. Tab sis vim nws txhawb nqa qhov ntsuas kub uas xav tau thiab nws tseem txaus kom ua cov pob tshab PCB. Yog li tsis muaj ado ntxiv cia pib….
Kauj Ruam 1: Txog Cov Txheej Txheem
Muaj ntau yam txuj ci los ua PCB. Qhov txheej txheem no txawv ntawm cov txheej txheem uas siv los hloov tus qauv (tsim qauv hauv Circuit). Koj tuaj yeem yooj yim kos lub Circuit Court ntawm tooj liab nrog tus tsim khoom ruaj khov. Tab sis qhov ntawd muab cov txiaj ntsig tsis raug. Or koj tuaj yeem siv cov txheej txheem hloov pauv toner. Hauv cov lus qhia no kuv yuav qhia koj yuav siv UV daim npog qhov ncauj kom hloov pauv qhov Circuit Court mus rau lub rooj tsav tooj liab. Nov yog txoj hauv kev uas siv txawm tias muaj ntau lawm ntawm PCB.
UV curable etch tiv taus yog txheej nyias nyias uas nyuaj thaum raug UV lub teeb. Qhov kev tawm tsam no tau muab tso rau ntawm lub rooj tsav tooj liab thiab nthuav tawm rau UV lub teeb los ntawm cov yeeb yaj kiab uas tsis pom kev uas suav nrog cov duab hauv Circuit Court. cov yeeb yaj kiab uas tsis tau kho thiab tau txais cov khoom siv hluav taws xob npaj kom tau txais cov ntawv ntxiv. Tsis txhob poob siab nrog cov lus tsim tawm, nws tsuas yog kev daws teeb meem qis xws li ci dej qab zib uas muaj peev xwm tshem tawm qhov tsis tiv taus UV tiv taus.
Muaj ob hom UV tiv thaiv cov yeeb yaj kiab uas zoo thiab tsis zoo. Thaum tus tsim tawm ntxiv, nthuav tawm ib feem ntawm daim duab tiv thaiv tseem tsis tau daws tau, thaum lwm qhov tau tawg.
Kauj ruam 2: Cov ntaub ntawv
- Daim iav raws li xav tau
- UV yees duab tiv thaiv
- Thaub qab dej qab zib
- Cov ntawv tooj liab
- Ferric tshuaj dawb
- Super kua nplaum (cyanoacralate)
- OHP luam tawm (hla lub taub hau projector luam tawm)
Kauj Ruam 3: Npaj Ua Ntej Tsim Kev Tsim Kho
Raws li tau hais hauv cov kauj ruam saum toj no peb xav tau cov qauv tsim hluav taws xob uas tau hloov mus rau daim ntawv pob tshab. tsim ib lub voj voog. Tus kheej kuv siv software tsim hluav taws xob online hu ua "EASY eda". Nws yog ib qho yooj yim kawm, tsis tau them nqi thiab yooj yim mus nrhiav cov khoom. Qhov mus dhau qee qhov kev qhia thiab koj yuav paub nrog nws.
Ua ntej ua daim duab schematic ntawm koj lub Circuit Court. Tom qab ntawd ua qauv PCB txheej txheem. Tom qab ntawd siv cov cuab yeej siv nws tus kheej, hla txoj hauv kev ntawm koj lub Circuit Court. Qhov no yuav zoo li nyuaj rau tus pib. Tab sis nrog qee qhov kev qhia koj yuav ua tau zoo.
Hauv kev tsim muaj ntau cov ntawv tsis xav tau thiab cov duab kos. Rau peb lub hom phiaj peb xav tau tsuas yog cov kab thiab cov pawm. Yog li tom qab koj txaus siab nrog koj qhov kev tsim cais cov kab thiab txheej txheej hauv txheej txheej pallet thiab xa cov duab ib yam li PNG.
Peb siv hom tsis zoo ntawm daim duab tawm tsam, uas txhais tau tias peb yuav tsum nthuav tawm qhov tawm tsam mus rau lub teeb yog peb xav tau nyob twj ywm tooj liab. taug qab thiab cov ntaub qhwv dawb rau ntawm keeb kwm yav dhau dub. Qhov dawb txhais tau tias OHP daim ntawv tseem pob tshab tom qab luam ntawv.
Kauj Ruam 4: Luam Ntawv Tsim
txog tam sim no peb muaj cov qauv tsim thiab xa tawm cov duab. Lub hom phiaj ntawm OHP luam tawm yog ua lub npog ntsej muag uas thaiv UV lub teeb pom kev zoo ntawm qhov tawm tsam hauv thaj chaw tsis xav tau. luam tawm tsis thaiv teeb pom kev zoo. Yog li ntawd 3 daim ntawv luam tau sib dhos thiab muab tso rau ntawm ib leeg thiab sib koom ua kom ruaj khov.
Kauj Ruam 5: Muab Cov Ntawv Tooj Liab rau GLASS
Raws li kuv tau hais los saum no Kuv yuav ua tooj liab uas nyob ntawm ib lub khob. Ua kom qhov no kuv lub hom phiaj yog txhawm rau muab cov ntawv tooj liab tso rau ntawm iav. cov ntawv tooj liab tuab ua rau cov txheej txheem ntau lub sijhawm kim. Qhov tuab ib ncig 0.05mm yog zoo meej.
Txhawm rau npaj iav, ua ntej peb yuav tsum tau ntxuav lub iav thiab cov ntawv ci tooj liab nrog cov cawv cawv. Tom qab ntxuav tso qee cov kua nplaum zoo rau ntawm iav thiab kis thoob lub khob. Tom qab ntawd muab cov ntawv ci tooj liab thiab nias ruaj khov. Neeg kom ntseeg tau tias tsis muaj cua npuas nyob nruab nrab ntawm iav thiab tooj liab ntawv. Rem tshem cov kua nplaum ntau dhau los ntawm kev nyem cov ntawv ci tooj liab. Cia nws kho kom zoo.
Kauj Ruam 6: Ua Ntawv Thov Tiv Thaiv Duab
ua ntej tshaj plaws txiav tawm qhov yuav tsum tau ua daim me me. Qhov duab tiv thaiv tuaj nrog npog hauv ob sab nrog ob daim npog npog. Cov duab tiv cov ntaub ntawv yog nplaum. Thaum lub hau tshem tawm nws tuaj yeem lo rau ntawm lub rooj tsav tooj liab tau yooj yim. Raws li kuv tau hais rau zaj yeeb yaj kiab tiv thaiv muaj ob daim npog. Ua kom lo daim duab tsis kam peb yuav tsum tshem daim npog.to ua li ntawd peb tuaj yeem lo ob daim ntawm daim kab xev nyob saum thiab hauv qab ntawm cov yeeb yaj kiab tiv thaiv. Los cov ntawv kab xev nws muaj peev xwm tshem tau daim npog. Tom qab ntawd ua tib zoo muab sab tsis pom ntawm tooj liab. maj mam nias lub yees duab kom tsis txhob txhawm rau lo lawv ob qho tib si zoo. Nco ntsoov tias koj tsis txhob ua huab cua npuas ntawm daim duab tiv zaj duab xis thiab tooj liab.
Kauj Ruam 7: Ua Teeb Kom Teeb Rau Lub Teeb
Tom qab siv daim duab tiv thaiv tam sim no peb yuav tsum tau teeb tsa. Qhov OHP luam tawm uas peb tau ua yav tas los. Nco ntsoov tso rau sab xis ntawm daim ntawv yog tias tsis yog tag nrho cov ntawv luam tawm tuaj yeem pom tom qab ntawd muab ib daim iav los ua kom ntseeg tau tias OHP luam tawm kom nruj rau ntawm lub rooj tsav tooj liab. nws lub sijhawm los nthuav tawm rau pom.
Kauj Ruam 8: Qhia rau Lub Teeb
Tam sim no peb yuav tsum nthuav tawm teeb tsa kom pom kev. Koj muaj txoj kev ywj pheej los siv cov khoom siv dag siv dag zog UV.bright lub hnub ci ci yog qhov zoo ntawm UV teeb. Nyob ib puag ncig 5 min ntawm kev nthuav tawm rau lub hnub ci yuav ua txoj haujlwm. Nco ntsoov ua kom tag nrho teeb tsa ruaj khov txawm tias tawm ntawm cov txheej txheem nthuav tawm. Qhov ntawd yog cov clip ua haujlwm tau zoo.
Tom qab 5-7min coj lub teeb tawm ntawm lub hnub ci ci thiab tshem tawm txhua yam. Koj yuav tsum pom me ntsis cov ntawv luam tau kho ntawm qhov tsis kam. Nws tau qhia hauv daim duab.
Kauj Ruam 9: Tsim Kev Tiv Thaiv
Cov yeeb yaj kiab tiv thaiv muaj lwm txheej txheej npog rau saum nws. Txhawm rau txhim kho nws. Peb yuav tsum tshem tawm qhov ntawd ntxiv.
Siv qee cov dej qab zib thiab ua qhov kev daws teeb meem tawm ntawm nws. Txhua qhov kev daws teeb meem yooj yim yuav teev nws txoj haujlwm. Yog tias koj tsis tuaj yeem pom cov dej qab zib rov qab, yaug cov hmoov kuj ua txoj haujlwm zoo kawg nkaus. Txawm li cas los xij tom qab ua tus tsim tawm (thim rov qab dej qab zib/ yaug hmoov tov) poob lub rooj tsavxwm thiab khaws ib pliag. Tom qab ntawd coj nws tawm thiab ntxuav maj mam. Koj yuav tsum pom Cov seem uas tsis tau pom yuav raug muab tshem tawm. Ua cov txheej txheem kom txog thaum tag nrho cov khoom uas tsis pom pom raug ntxuav tawm.
Thaum kawg koj yuav xaus nrog lub rooj tsav tooj liab nrog cov kab uas kho tau zoo Tam sim no nws yog lub sijhawm los cim …
Kauj ruam 10: Etching
Siv qee qhov nyiaj ntawm ferric cloride hmoov thiab yaj hauv kwv yees li 150ml ntawm cov dej qhov kev daws teeb meem yuav tsum tsaus. Yog tias tsis ntxiv ferric cloride ntau ntxiv. Tom qab ua qhov kev daws teeb meem poob lub tooj liab tooj liab hauv cov tshuaj. Tsoo lub rooj tsavxwm ntau zaus kom ua tau zoo Tom qab ib ncig 10-15 feeb tag nrho cov tooj liab uas tsis xav tau tuaj yeem tshem tawm txoj kev seem.
Kauj Ruam 11: Cov Khoom Kawg
Nrog qee qhov acetone lossis dej sov nws tuaj yeem tshem tawm qhov tawm tsam hla txoj kev tooj liab.
Yog li dab tsi tam sim no,,. ua PCB ntawm Cov iav yuav tsis muab cov khoom siv hluav taws xob zoo. Qhov hom kev siv hluav taws xob no tuaj yeem siv rau ntau qhov haujlwm cuam tshuam nrog kev ua kom pom kev yog qhov xav tau.such raws li cov teeb tsa coj los ntawm hom Circuit Court no yuav txaus.
Cov txheej txheem no qhib txoj hauv kev rau ntau yam muaj tswv yim. Txawm ntawm qhov nkhaus peb tuaj yeem tsim PCB. Hloov iav nrog kab xev kapton nws muaj peev xwm ua kom hloov pauv tau yooj yim.
Kuv yuav tso qhov no ntawm no. Kuv xav tias koj tau kawm qee yam tshiab ……
