Uyilo oluSetyenzisiweyo oluvela kwi-Laser Etching PCB
Njengenxalenye ebalulekileyo kwizixhobo ze-elektroniki, i-PCB (ibhodi yesekethe eprintiweyo) yokuyila nokuyila iyinto exhalabisa kakhulu abavelisi bezixhobo ze-elektroniki. Usenokuba uqhelene nobuchwepheshe bendabuko bokuprinta be-pcb njengendlela yokudlulisa i-toner kwaye ude uziqhelise ngokwakho. Apha ndifuna ukwabelana nawe ngezinye iindlela zokukrola ze-pcb nge-CO2 laser cutter, ekuvumela ukuba wenze ngokwezifiso ii-pcb ngokweedizayini zakho ozithandayo.
Umgaqo kunye nobuchule bokukrola i-pcb
- Yazisa ngokufutshane ibhodi yesekethe eprintiweyo
Uyilo olulula lwe-pcb lwakhiwe ngomaleko wokukhusela kunye neeleya ezimbini zobhedu (ezikwabizwa ngokuba yi-copper clad). Ngokwesiqhelo i-FR-4 (iglasi elukiweyo kunye ne-epoxy) zizinto eziqhelekileyo ezisebenza njenge-insulation, okwangoku ngokusekelwe kwiimfuno ezahlukeneyo kwimisebenzi ethile, uyilo lwesekethe, kunye nobukhulu bebhodi, ezinye ii-dielectrics ezifana ne-FR-2 (iphepha le-phenolic cotton), i-CEM-3 (iglasi engalukwanga kunye ne-epoxy) nazo zingasetyenziswa. Umaleko wobhedu uthatha uxanduva lokuhambisa isignali yombane ukwakha unxibelelwano phakathi kweeleya ngokusebenzisa iileya zokukhusela ngoncedo lwemingxuma edlulayo okanye i-solder ebekwe kumphezulu. Ke ngoko, injongo ephambili yokukrola i-pcb kukudala ii-traces zesekethe nge-copper kunye nokususa ubhedu olungenamsebenzi okanye ukuzenza zahlulwe omnye komnye.
Njengoko sijonga umgaqo wokugrumba we-pcb, sijonga iindlela eziqhelekileyo zokugrumba. Kukho iindlela ezimbini ezahlukeneyo zokusebenza ezisekelwe kumgaqo ofanayo wokugrumba ubhedu olugqunyiweyo.
- Izisombululo zokupeyinta zePCB
Enye imele ingcinga ethe ngqo, eyokususa ezinye iindawo zobhedu ezingasebenziyo ngaphandle kwemigca yesekethe. Ngokwesiqhelo, sisebenzisa isisombululo sokugrumba esifana ne-ferry chloride ukuze sifezekise inkqubo yokugrumba. Ngenxa yeendawo ezinkulu eziza kugrumba, kufuneka kuthathwe ixesha elide kunye nomonde omkhulu.
Enye indlela inobuchule ngakumbi bokukrola umgca osikiweyo (masithi ngokuchanekileyo - umphezulu woyilo lwesekethe), okukhokelela ekuqhutyweni kwesekethe ngokuchanekileyo ngelixa kwahlula iphaneli yobhedu engafanelekanga. Kule meko, ithusi elincinci liyakrolwa kwaye ixesha elincinci lichithwa. Apha ngezantsi ndiza kugxila kwindlela yesibini yokuchaza iinkcukacha zendlela yokukrola i-pcb ngokwefayile yoyilo.
Indlela yokukrola i-pcb
Zeziphi izinto ekufuneka zilungiswe:
ibhodi yesekethe (ibhodi yentsimbi), ipeyinti yokutshiza (i-matte emnyama), ifayile yoyilo lwe-pcb, umsiki we-laser, isisombululo se-ferric chloride (sokukrola ubhedu), isicoci sotywala (sokucoca), isisombululo sokuhlamba i-acetone (sokunyibilikisa ipeyinti), iphepha lesanti (sokupolisha ibhodi yobhedu)
Amanyathelo Okusebenza:
1. Phatha ifayile yoyilo lwePCB kwifayile yevektha (umgca ongaphandle uza kukrolwa nge-laser) kwaye uyilayishe kwinkqubo yelaser
2. Musa ukurhangqa ibhodi egqunywe ngobhedu ngephepha lokusila, uze ucoce ubhedu nge-rubbing alcohol okanye i-acetone, uqinisekise ukuba akukho oyile kunye namafutha aseleyo.
3. Bamba ibhodi yesekethe kwi-pliers uze upeyinte i-spray encinci kuloo nto
4. Beka ibhodi yobhedu etafileni yokusebenza uze uqalise ukupeyinta umphezulu nge-laser
5. Emva kokugcaba, sula intsalela yepeyinti egcabayo usebenzisa utywala
6. Yifake kwisisombululo se-PCB etchant (i-ferric chloride) ukuze ikhuphe ubhedu oluveziweyo
7. Sombulula ipeyinti yokutshiza nge-acetone washing solvent (okanye i-remover yepeyinti efana ne-Xylene okanye i-paint thinner). Hlamba okanye usule ipeyinti emnyama eseleyo kwiibhodi.
8. Bhoboza imingxunya
9. Thengisa izinto ze-elektroniki ngemingxunya
10. Igqityiwe
Kutheni ukhetha i-laser etching pcb
Kubalulekile ukuqaphela ukuba umatshini we-laser we-CO2 ubhala ipeyinti yokutshiza umphezulu ngokwemikhondo yesekethe endaweni yobhedu. Yindlela ekrelekrele yokukrola ubhedu oluveziweyo ngeendawo ezincinci kwaye lunokwenziwa ekhaya. Kwakhona, umsiki we-laser onamandla aphantsi uyakwazi ukwenza oku ngenxa yokususwa lula kwepeyinti yokutshiza. Ukufumaneka lula kwezinto kunye nokusebenza lula komatshini we-laser we-CO2 kwenza le ndlela ithandwe kwaye ibe lula, ngaloo ndlela ungayenza i-pcb ekhaya, uchithe ixesha elincinci. Ngaphezu koko, ukwenza iiprototype ngokukhawuleza kunokufezekiswa yi-pcb yokukrola i-laser ye-CO2, okuvumela uyilo olwahlukeneyo lwe-pcbs ukuba lwenziwe ngokwezifiso kwaye lufezekiswe ngokukhawuleza. Ngaphandle kokuguquguquka koyilo lwe-pcb, kukho into ephambili malunga nokuba kutheni ukhethe umsiki we-laser we-co2 ukuba ukuchaneka okuphezulu kunye nomqadi we-laser ocolekileyo kuqinisekisa ukuchaneka koqhagamshelo lwesekethe.
(Ingcaciso eyongezelelweyo - umsiki we-laser we-co2 unamandla okukrola nokukrola kwizinto ezingezizo ezesinyithi. Ukuba udidekile ngumsiki we-laser kunye nomkroli we-laser, nceda ucofe ikhonkco ukuze ufunde okungakumbi:Umahluko: umkroli welaser VS umsiki welaser | (mimowork.com)
Umatshini wokukrola we-CO2 laser pcb ulungele umaleko wesignali, iileya ezimbini kunye neeleya ezininzi ze-pcb. Ungawusebenzisa ukwenza uyilo lwakho lwe-pcb ekhaya, kwaye ufake umatshini we-CO2 laser kwimveliso esebenzayo ye-pcbs. Ukuphindaphinda okuphezulu kunye nokuhambelana kokuchaneka okuphezulu ziingenelo ezintle zokukrola kwe-laser kunye nokukrola kwe-laser, okuqinisekisa umgangatho ophezulu wee-PCB. Ulwazi oluneenkcukacha onokulufumanaumkroli welaser 100.
Ukukrola i-PCB enye nge-UV laser, i-fiber laser
Ngaphezu koko, ukuba ufuna ukufezekisa ukucubungula okukhawulezayo kunye neenkqubo ezimbalwa zokwenza ii-pcb, i-UV laser, i-green laser kunye nomatshini we-fiber laser zinokuba lukhetho olufanelekileyo. Ukukrola ubhedu ngqo nge-laser ukuze ushiye imikhondo yesekethe kunika lula kakhulu kwimveliso yemizi-mveliso.
✦ Uthotho lwamanqaku luza kuhlala luhlaziywa, unokufumana okungakumbi malunga nokusika i-UV laser kunye nokukrola i-laser kwi-pcbs kwinqaku elilandelayo.
