Kev Tsim Qauv Tshwj Xeeb los ntawm Laser Etching PCB
Raws li ib qho tseem ceeb hauv cov khoom siv hluav taws xob, PCB (printed circuit board) ntawm kev tsim thiab tsim khoom yog qhov kev txhawj xeeb loj rau cov tuam txhab tsim khoom siv hluav taws xob. Tej zaum koj yuav paub txog cov thev naus laus zis luam ntawv pcb ib txwm muaj xws li txoj kev hloov pauv toner thiab txawm tias xyaum nws ntawm koj tus kheej. Ntawm no kuv xav qhia rau koj lwm txoj hauv kev etching pcb nrog lub tshuab txiav laser CO2, uas tso cai rau koj hloov kho cov pcbs raws li koj cov qauv tsim nyiam.
Lub hauv paus ntsiab lus thiab cov txheej txheem ntawm pcb etching
- Qhia luv luv txog lub rooj tsavxwm luam tawm
Tus qauv pcb yooj yim tshaj plaws yog tsim los ntawm cov txheej rwb thaiv tsev thiab ob txheej tooj liab (tseem hu ua tooj liab clad). Feem ntau FR-4 (iav woven thiab epoxy) yog cov khoom siv dav dav los ua rwb thaiv tsev, thaum lub sijhawm raws li ntau yam kev thov ntawm cov haujlwm tshwj xeeb, cov qauv tsim hluav taws xob, thiab qhov loj ntawm lub rooj tsavxwm, qee cov dielectrics xws li FR-2 (ntawv paj rwb phenolic), CEM-3 (iav tsis-woven thiab epoxy) kuj tuaj yeem siv tau. Cov txheej tooj liab lav ris rau kev xa cov teeb liab hluav taws xob los tsim kev sib txuas ntawm cov txheej los ntawm cov txheej rwb thaiv tsev nrog kev pab los ntawm cov qhov lossis cov khoom siv solder saum npoo. Yog li ntawd, lub hom phiaj tseem ceeb ntawm etching pcb yog los tsim cov kab hluav taws xob nrog tooj liab thiab tshem tawm cov tooj liab tsis muaj txiaj ntsig lossis ua rau lawv cais tawm ntawm ib leeg.
Muaj ib qho kev saib luv luv ntawm lub hauv paus ntsiab lus ntawm pcb etching, peb yuav saib cov txheej txheem etching ib txwm muaj. Muaj ob txoj hauv kev ua haujlwm sib txawv raws li tib lub hauv paus ntsiab lus los txiav cov tooj liab clad.
- Cov kev daws teeb meem PCB etching
Ib tug neeg xav txog kev ncaj qha uas yog tshem tawm cov chaw tsis muaj txiaj ntsig ntawm tooj liab tsuas yog cov kab ntawm lub voj voog xwb. Feem ntau, peb siv cov tshuaj etching xws li ferry chloride los ua kom tiav cov txheej txheem etching. Vim tias thaj chaw loj yuav tsum tau etched, yuav tsum siv sijhawm ntev thiab ua siab ntev heev.
Lwm txoj kev yog qhov ntse dua los kos cov kab txiav (hais kom meej dua - cov qauv ntawm lub voj voog teeb tsa), ua rau muaj kev sib txuas lus ntawm lub voj voog thaum cais cov vaj huam sib luag tooj liab tsis tseem ceeb. Hauv qhov xwm txheej no, tooj liab tsawg dua raug kos thiab siv sijhawm tsawg dua. Hauv qab no kuv yuav tsom mus rau txoj kev thib ob los qhia meej txog yuav ua li cas kos ib lub pcb raws li cov ntaub ntawv tsim.
Yuav ua li cas txiav ib lub pcb
Yuav tsum npaj dab tsi:
Rooj tsav xwm hluav taws xob (tooj liab cladboard), xim tsuag (dub matte), cov ntaub ntawv tsim pcb, tshuab txiav laser, kua ferric chloride (los txiav tooj liab), so cawv (los ntxuav), kua ntxuav acetone (los yaj cov xim), ntawv xuab zeb (los txhuam tooj liab board)
Cov Kauj Ruam Ua Haujlwm:
1. Ua cov ntaub ntawv tsim PCB rau cov ntaub ntawv vector (qhov contour sab nraud yuav raug laser etched) thiab thauj nws mus rau hauv lub laser system
2. Tsis txhob siv ntawv xuab zeb los txhuam lub rooj tsavxwm tooj liab, thiab ntxuav cov tooj liab nrog cov cawv txhuam lossis acetone, kom ntseeg tau tias tsis muaj roj thiab roj seem.
3. Tuav lub rooj tsavxwm hauv cov pliers thiab muab ib qho xim pleev xim nyias rau ntawm qhov ntawd
4. Muab lub rooj tsavxwm tooj liab tso rau ntawm lub rooj ua haujlwm thiab pib laser etching qhov chaw pleev xim
5. Tom qab etching, so cov xim etched seem siv cawv.
6. Muab tso rau hauv cov tshuaj PCB etchant (ferric chloride) los txiav cov tooj liab uas raug tshem tawm.
7. Siv cov tshuaj ntxuav acetone (lossis cov tshuaj tshem xim xws li Xylene lossis cov tshuaj pleev xim thinner) los ntxuav cov xim tsuag. Muab dej los yog so cov xim dub uas seem ntawm cov laug cam kom huv si.
8. Tho cov qhov
9. Siv cov khoom siv hluav taws xob los ntawm cov qhov
10. Tiav lawm
Vim li cas thiaj xaiv laser etching pcb
Tsim nyog sau tseg, tias lub tshuab CO2 laser txiav cov xim tsuag saum npoo raws li cov kab ntawm lub voj voog es tsis yog tooj liab. Nws yog ib txoj hauv kev ntse los txiav cov tooj liab uas raug rau thaj chaw me me thiab tuaj yeem ua tiav hauv tsev. Tsis tas li ntawd, lub tshuab txiav laser qis zog tuaj yeem ua nws ua tsaug rau qhov yooj yim tshem tawm cov xim tsuag. Qhov yooj yim muaj cov ntaub ntawv thiab kev ua haujlwm yooj yim ntawm lub tshuab CO2 laser ua rau txoj kev nrov thiab yooj yim, yog li koj tuaj yeem ua pcb hauv tsev, siv sijhawm tsawg dua. Ntxiv mus, kev tsim qauv sai tuaj yeem ua tiav los ntawm CO2 laser engraving pcb, tso cai rau ntau yam qauv pcbs kom raug kho thiab ua tiav sai. Dhau li ntawm qhov yooj ywm ntawm kev tsim pcb, muaj ib qho tseem ceeb txog vim li cas thiaj xaiv co2 laser cutter uas qhov tseeb siab nrog lub teeb laser zoo ua kom ntseeg tau qhov tseeb ntawm kev sib txuas ntawm lub voj voog.
(Piav qhia ntxiv - co2 laser cutter muaj peev xwm engraving thiab etching rau cov khoom tsis yog hlau. Yog tias koj tsis meej pem nrog lub laser cutter thiab laser engraver, thov nyem qhov txuas kom paub ntau ntxiv:Qhov Txawv: laser engraver VS laser cutter | (mimowork.com)
Lub tshuab CO2 laser pcb etching yog tsim rau txheej teeb liab, ob txheej thiab ntau txheej ntawm pcbs. Koj tuaj yeem siv nws los ua koj tus qauv pcb hauv tsev, thiab tseem muab lub tshuab CO2 laser rau hauv kev tsim pcbs. Kev rov ua dua siab thiab kev sib xws ntawm qhov tseeb siab yog qhov zoo heev rau laser etching thiab laser engraving, kom ntseeg tau tias qhov zoo tshaj plaws ntawm PCBs. Cov ntaub ntawv ntxaws kom tau txais los ntawmlaser txiav 100.
Ib zaug dhau PCB etching los ntawm UV laser, fiber laser
Tsis tas li ntawd xwb, yog tias koj xav ua kom tiav cov txheej txheem ceev ceev thiab tsawg dua cov txheej txheem rau kev ua pcbs, UV laser, laser ntsuab thiab fiber laser tshuab yuav yog cov kev xaiv zoo tshaj plaws. Kev txiav cov tooj liab ncaj qha los ntawm laser kom tawm ntawm cov kab hluav taws xob muab kev yooj yim heev rau kev tsim khoom lag luam.
✦ Cov ntawv xov xwm yuav hloov kho tshiab, koj tuaj yeem tau txais ntau ntxiv txog UV laser txiav thiab laser etching ntawm pcbs hauv qhov tom ntej.
