Umklamo Owenziwe Ngokwezifiso Ovela ku-Laser Etching PCB
Njengengxenye ebalulekile ezingxenyeni ze-elekthronikhi, i-PCB (ibhodi lesifunda eliphrintiwe) lokuklama nokwakha liyindaba enkulu kubakhiqizi be-elekthronikhi. Ungase ujwayelene nobuchwepheshe bendabuko bokuphrinta be-pcb njengendlela yokudlulisa i-toner futhi uze uzijwayeze ngokwakho. Lapha ngifuna ukwabelana nawe ngezinye izindlela zokuqopha ze-pcb nge-CO2 laser cutter, okukuvumela ukuthi wenze ngokwezifiso ama-pcb ngokwemiklamo oyithandayo.
Isimiso kanye nobuchwepheshe bokuqopha i-pcb
- Yethula kafushane ibhodi lesifunda eliphrintiwe
Umklamo we-pcb olula kakhulu wakhiwe ngesendlalelo sokuvikela kanye nezendlalelo ezimbili zethusi (ezibizwa nangokuthi i-copper clad). Ngokuvamile i-FR-4 (ingilazi elukiwe kanye ne-epoxy) iyinto evamile yokusebenza njengokuvikela, okwamanje ngokusekelwe ezidingweni ezahlukahlukene zemisebenzi ethile, imiklamo yesekethe, kanye nosayizi webhodi, ezinye izinto ze-dielectric ezifana ne-FR-2 (iphepha lekotoni le-phenolic), i-CEM-3 (ingilazi engalukiwe kanye ne-epoxy) nazo zingasetshenziswa. Isendlalelo sethusi sithatha umthwalo wemfanelo wokuletha isignali kagesi ukwakha uxhumano phakathi kwezingqimba ngezingqimba zokuvikela ngosizo lwezimbobo ezidlulayo noma i-solder ebekwe phezu kwayo. Ngakho-ke, inhloso eyinhloko yokuqopha i-pcb ukudala imikhondo yesekethe ngethusi kanye nokususa ithusi elingasebenzi noma ukulenza lihlukaniswe.
Njengoba sibheka kafushane isimiso sokusika i-pcb, sibheka izindlela ezijwayelekile zokusika. Kunezindlela ezimbili ezihlukene zokusebenza ezisekelwe kusimiso esifanayo sokusika ithusi elimboziwe.
- Izixazululo zokuqopha ze-PCB
Umuntu ungowokucabanga okuqondile okuwukususa ezinye izindawo zethusi ezingenamsebenzi ngaphandle kwemigqa yesekethe. Ngokuvamile, samukela isisombululo sokusika njenge-ferry chloride ukuze sifeze inqubo yokusika. Ngenxa yezindawo ezinkulu okufanele zisikwe, kudingeka isikhathi eside kanye nesineke esikhulu.
Enye indlela ihlakaniphile kakhulu ukuqopha umugqa osikiwe (masithi ngokunembile - uhlaka lwesakhiwo sesekethe), okuholela ekuqhutshweni kwesekethe okunembile ngenkathi kususwa iphaneli yethusi engafanele. Kulesi simo, ithusi elincane liyaqopha futhi isikhathi esincane siyachithwa. Ngezansi ngizogxila endleleni yesibili ukuze ngichaze ukuthi iqopha kanjani i-pcb ngokwefayela lomklamo.
Indlela yokudweba i-pcb
Izinto okufanele zilungiswe:
ibhodi lesifunda (ibhodi le-clad lethusi), upende wokufutha (omnyama ongacwebezeli), ifayela lomklamo we-pcb, umsiki we-laser, isixazululo se-ferric chloride (sokuqopha ithusi), i-alcohol wipe (yokuhlanza), isixazululo sokuwasha i-acetone (sokuncibilikisa upende), i-sandpaper (yokupholisha ibhodi lethusi)
Izinyathelo Zokusebenza:
1. Phatha ifayela lokuklama le-PCB libe ifayela le-vector (uhlaka lwangaphandle luzoqoshwa nge-laser) bese ulifaka ohlelweni lwe-laser
2. Ungaligoqi ibhodi elimbozwe ngethusi ngephepha lokusanta, bese uhlanza ithusi nge-rubbing alcohol noma i-acetone, uqinisekise ukuthi akukho mafutha namafutha asele.
3. Bamba ibhodi lesekhethi eziplazini bese upenda upende omncane wokufutha kulokho
4. Beka ibhodi yethusi etafuleni lokusebenza bese uqala ukupeyinta ubuso nge-laser
5. Ngemva kokuqopha, sula insalela yopende oqophayo usebenzisa utshwala
6. Yifake esixazululweni se-PCB etchant (i-ferric chloride) ukuze uqophe ithusi eliveziwe
7. Xuba upende ofafazwayo nge-acetone washing solvent (noma i-remover yopende efana ne-Xylene noma i-paint thinner). Geza noma usule upende omnyama osele emabhodini.
8. Bhoboza imigodi
9. Thela izinto zikagesi ngemigodi
10. Kuqediwe
Kungani ukhethe i-laser etching PCB
Kufanele kuqashelwe ukuthi umshini we-laser we-CO2 uqopha upende wokufutha wobuso ngokwemikhondo yesekethe esikhundleni sethusi. Kuyindlela ehlakaniphile yokuqopha ithusi eliveziwe ngezindawo ezincane futhi lingenziwa ekhaya. Futhi, umsiki we-laser onamandla aphansi uyakwazi ukukwenza ngenxa yokususwa kalula kopende wokufutha. Ukutholakala kalula kwezinto zokwakha kanye nokusebenza okulula komshini we-laser we-CO2 kwenza indlela ithandwe futhi ibe lula, ngakho-ke ungenza i-pcb ekhaya, uchithe isikhathi esincane. Ngaphezu kwalokho, ukwenza i-prototyping esheshayo kungabonakala nge-pcb yokuqopha i-laser ye-CO2, okuvumela imiklamo ehlukahlukene ye-pcbs ukuthi yenziwe ngezifiso futhi ibonakale ngokushesha. Ngaphandle kokuguquguquka komklamo we-pcb, kunesici esibalulekile mayelana nokuthi kungani ukhethe umsiki we-laser we-co2 ukuthi ukunemba okuphezulu ngomsebe we-laser omncane kuqinisekisa ukunemba kokuxhumeka kwesekethe.
(Incazelo eyengeziwe - umsiki we-laser we-co2 unekhono lokuqopha nokuqopha ezintweni ezingezona ezensimbi. Uma udidekile ngomsiki we-laser nomsiki we-laser, sicela uchofoze isixhumanisi ukuze ufunde kabanzi:Umehluko: umqophi we-laser VS umsiki we-laser | (mimowork.com)
Umshini wokuqopha we-laser pcb we-CO2 ulungele ungqimba lwesignali, izendlalelo ezimbili kanye nezendlalelo eziningi ze-pcb. Ungawusebenzisa ukwenza umklamo wakho we-pcb ekhaya, futhi ufake umshini we-laser we-CO2 ekukhiqizweni kwe-pcb okusebenzayo. Ukuphindaphinda okuphezulu kanye nokuvumelana kokunemba okuphezulu kuyinzuzo enhle kakhulu yokuqopha kwe-laser kanye nokuqopha nge-laser, okuqinisekisa ikhwalithi ephezulu yama-PCB. Ulwazi oluningiliziwe ongaluthola kuloumqophi we-laser 100.
Ukuqopha kwe-PCB okudlula kanye nge-UV laser, i-fiber laser
Ngaphezu kwalokho, uma ufuna ukucubungula ngesivinini esikhulu kanye nezinqubo ezimbalwa zokwenza ama-pcb, i-UV laser, i-green laser kanye nomshini we-fiber laser kungaba ukukhetha okuhle. Ukuqopha ithusi ngokuqondile nge-laser ukuze kushiye iminonjana yesekethe kunikeza lula kakhulu ekukhiqizweni kwezimboni.
✦ Uchungechunge lwezihloko luzoqhubeka lubuyekezwa, ungathola okwengeziwe mayelana nokusika i-UV laser kanye nokuqoshwa kwe-laser kuma-pcb esikhathini esizayo.
