Idizayini Yangokwezifiso evela ku-Laser Etching PCB
Njengengxenye ebalulekile ezingxenyeni ze-elekthronikhi, i-PCB (ibhodi lesekethe eliphrintiwe) lokuklama nokwakha libakhathaza kakhulu abakhiqizi bezinto zikagesi.Ungase ujwayelane nobuchwepheshe bokuphrinta be-pcb bendabuko njengendlela yokudlulisa ithoni futhi uze uzilolonge ngokwakho.Lapha ngifuna ukwabelana nawe ezinye izindlela pcb etching nge CO2 laser cutter, ukuvumela ukuba nezimo ngokwezifiso pcbs ngokusho imiklamo oyikhethayo.
Isimiso kanye namasu we-pcb etching
- Yethula kafushane ibhodi lesifunda eliphrintiwe
Umklamo olula we-pcb wakhiwe ngongqimba oluvikelayo kanye nezingqimba ezimbili zethusi (ezibizwa nangokuthi i-copper clad).Imvamisa i-FR-4(ingilazi elukiweyo ne-epoxy) iyinto evamile ukusebenza njenge-insulation, okwamanje ngokusekelwe ezidingweni ezihlukahlukene zemisebenzi ethile, imiklamo yesekethe, nosayizi bebhodi, amanye ama-dielectrics afana ne-FR-2(phenolic cotton paper), I-CEM-3 (ingilazi engalukiwe ne-epoxy) nayo ingamukelwa.Isendlalelo sethusi sithatha umthwalo wemfanelo wokuletha isignali kagesi ukuze kwakhiwe uxhumano phakathi kwezingqimba ngokusebenzisa izendlalelo zokufakelwa ngosizo lwezimbobo noma i-solder-mount-mount solder.Ngakho-ke, inhloso eyinhloko ye-etching pcb ukudala iminonjana yesifunda ngethusi kanye nokuqeda ithusi elingenamsebenzi noma ukubenza bahlukane.
Ukuba nokulunguza okufushane ku-pcb etching isimiso, sibheka izindlela ezijwayelekile zokuqopha.Kunezindlela ezimbili ezihlukene zokusebenza ezisekelwe kumgomo ofanayo wokunamathisela ithusi eligqoke.
- PCB etching izixazululo
Omunye ungowokucabanga okuqondile okungukususa ezinye izindawo zethusi ezingenamsebenzi ngaphandle kwemikhondo yesifunda.Imvamisa, sisebenzisa isixazululo se-etching njenge-ferry chloride ukuze sifinyelele inqubo yokufaka.Ngenxa yezindawo ezinkulu ezizoqoshwa, isikhathi eside sidinga ukuthathwa kanye nokubekezela okukhulu.
Enye indlela ihlakaniphe kakhulu ukuqopha umugqa wokusika (ukusho ngokunembile - uhlaka lwesakhiwo sesifunda), okuholela ekuqhutshweni kwesifunda okunembile ngenkathi kuhlukaniswa iphaneli yethusi engabalulekile.Kulesi simo, ithusi elincane liyabhalwa futhi kudliwe isikhathi esincane.Ngezansi ngizogxila endleleni yesibili yokucacisa ukuthi ungayifaka kanjani i-pcb ngokusho kwefayela lokuklama.
Ungayifaka kanjani i-pcb |
Yiziphi izinto okufanele zilungiswe:
ibhodi lesifunda (copper clad), spray paint (black matte), pcb design file, laser cutter, ferric chloride solution (to etch the copper), alcohol Sula (ukuhlanza), i-acetone washing solution (ukuncibilikisa upende), sandpaper ( ukupholisha ibhodi lethusi)
Izinyathelo zokusebenza:
1. Phatha ifayela lokuklama le-PCB efayeleni le-vector (i-contour yangaphandle izoqoshwa nge-laser) bese uyilayisha ohlelweni lwe-laser.
2. Ungalinge ulungise ibhodi eligqoke ithusi nge-sandpaper, futhi uhlanze ithusi ngotshwala obuhlikihlayo noma i-acetone, uqinisekise ukuthi awekho amafutha namafutha asele.
3. Bamba ibhodi lesifunda ku-pliers futhi unikeze umdwebo omncane wesifutho kulokho
4. Beka ibhodi yethusi etafuleni lokusebenza bese uqala i-laser etching umdwebo ongaphezulu
5. Ngemva kokuqopha, sula insalela kapende egxilile usebenzisa utshwala
6. Yifake kusixazululo se-PCB etchant (i-ferric chloride) ukuze unamathisele ithusi eliveziwe.
7. Xazulula upende wesifutho nge-acetone washing solvent (noma isikhiphi sikapende esinjenge-Xylene noma isinciphisi sopende).Geza noma usule upende omnyama osele emabhodini uyafinyeleleka.
8. Geza izimbobo
9. Solder izinto zikagesi ngokusebenzisa izimbobo
10. Kuqediwe
Kungani ukhetha i-laser etching pcb
Okubalulekile ukuqaphela, ukuthi umshini we-CO2 laser unamathisela upende wesifutho ongaphezulu ngokulandela umkhondo wesekethe esikhundleni sethusi.Kuyindlela ehlakaniphile yokufaka ithusi eliveziwe elinezindawo ezincane futhi lingabulawa ekhaya.Futhi, i-laser cutter enamandla aphansi iyakwazi ukuyenza ngenxa yokukhishwa kalula kopende wesifutho.Ukutholakala kalula kwezinto kanye nokusebenza okulula komshini we-laser CO2 kwenza indlela ethandwa futhi ibe lula, ngaleyo ndlela ungenza i-pcb ekhaya, uchithe isikhathi esincane.Ngaphezu kwalokho, i-prototyping esheshayo ingabonakala nge-CO2 laser eqoshiwe pcb, evumela imiklamo ehlukahlukene yama-pcbs ukuba yenziwe ngezifiso futhi ibonakale ngokushesha.Ngaphandle kokuguquguquka kokuklama kwe-pcb, kunesici esibalulekile mayelana nokuthi kungani ukhetha i-co2 laser cutter ukuthi ukunemba okuphezulu ngogongolo oluhle lwe-laser kuqinisekisa ukunemba kokuxhumeka kwesifunda.
(Incazelo eyengeziwe - i-co2 laser cutter inekhono lokuqopha nokunamathisela ezintweni ezingezona ezensimbi. Uma udidekile nomsiki we-laser nomqophi we-laser, sicela uchofoze isixhumanisi ukuze ufunde kabanzi:Umehluko: laser engraver VS laser cutter |(mimowork.com)
I-CO2 laser pcb etching machine ilungele ungqimba lwesignali, izendlalelo eziphindwe kabili kanye nezingqimba eziningi zama-pcbs.Ungayisebenzisa ukuze diy pcb design yakho ekhaya, futhi ufake umshini laser CO2 ekukhiqizeni pcbs esiwusizo.Ukuphindaphinda okuphezulu nokuvumelana kokunemba okuphezulu kuyizinzuzo ezinhle kakhulu zokuqoshwa kwe-laser nokuqoshwa kwe-laser, okuqinisekisa ikhwalithi ye-premium yama-PCB.Imininingwane eminingi ongayithola kuyoumqophi we-laser 100.
Ukufakwa kwe-PCB ye-pass eyodwa nge-UV laser, i-fiber laser
Ngaphezu kwalokho, uma ufuna ukubona ukucutshungulwa kwesivinini esikhulu kanye nezinqubo ezincane zokwenza ama-pcbs, i-laser ye-UV, umshini we-laser eluhlaza kanye nomshini we-fiber laser kungase kube ukukhetha okuhle.Ngokuqondile i-laser etching ithusi ukushiya iminonjana yesifunda inikeza lula kakhulu ekukhiqizweni kwezimboni.
✦ Uchungechunge lwezihloko luzoqhubeka lubuyekezwa, ungathola okwengeziwe mayelana nokusika kwe-UV laser kanye ne-laser etching kuma-pcbs ngokulandelayo.
