Uyilo oluSiko oluvela kwi-Laser Etching PCB
Njengenxalenye engundoqo kumacandelo e-elektroniki, i-PCB (ibhodi yesekethe eprintiweyo) yoyilo kunye nokuyila iyinkxalabo enkulu kubenzi bombane.Usenokuba uqhelene neteknoloji pcb yoshicilelo zemveli njenge toner indlela yokudlulisa kwaye nokuba uziqhelanise ngokwakho.Apha ndifuna ukwabelana nawe ezinye iindlela pcb etching kunye CO2 laser cutter, ikuvumela ukuba bhetyebhetye ulungise pcbs ngokwendlela uyilo olukhethayo.
Umgaqo kunye nobuchule be-pcb etching
- Yazisa ngokufutshane ibhodi yesekethe eprintiweyo
Olona yilo lulula lwe-pcb lwakhiwe nge-insulating layer kunye nemigangatho emibini yobhedu (ekwabizwa ngokuba yi-copper clad).Ngokuqhelekileyo i-FR-4 (iglasi ephothiweyo kunye ne-epoxy) yinto eqhelekileyo ukuba isebenze njenge-insulation, okwangoku ngokusekelwe kwiimfuno ezahlukeneyo kwimisebenzi ethile, uyilo lwesekethe, kunye nobukhulu bebhodi, ezinye ii-dielectrics ezifana ne-FR-2 (phenolic cotton paper), I-CEM-3 (iglasi engalukiweyo kunye ne-epoxy) nayo ingamkelwa.Umaleko wobhedu uthatha uxanduva lokuhambisa umqondiso wombane wokwakha uxhulumaniso phakathi kweengqimba ngokusebenzisa i-insulation layers ngoncedo lwe- through-holes or surface-mount solder.Ke ngoko, eyona njongo iphambili ye-etching pcb kukudala umkhondo wesekethe ngobhedu kunye nokuphelisa ubhedu olungenamsebenzi okanye ubenze bahlukane.
Ukuba ne-peek emfutshane kwi-pcb etching umgaqo, sijonga iindlela eziqhelekileyo zokuhombisa.Kukho iindlela ezimbini ezahlukeneyo zokusebenza ezisekelwe kumgaqo ofanayo wokutshiza ubhedu olugqunyiweyo.
-Izisombululo zePCB etching
Omnye ungowokucinga ngokuthe ngqo okukukususa ezinye iindawo zobhedu ezingenamsebenzi ngaphandle kwemikhondo yesekethe.Ngokwesiqhelo, sithatha isisombululo sokutsala esinje nge-ferry chloride ukufezekisa inkqubo yokufaka.Ngenxa yeendawo ezinkulu eziza kufakwa, ixesha elide kufuneka lithathwe kunye nomonde omkhulu.
Enye indlela inobuchule ngakumbi ukukhupha umgca wokusikwa (ngokuchanekileyo ngakumbi - ulwandlalo lwesakhiwo sesekethe), ekhokelela ekuqhutyweni kwesiphaluka esichanekileyo ngelixa uhlukanisa ipaneli yobhedu engabalulekanga.Kulo mqathango, ubhedu oluncinci luyabhalwa kwaye ixesha elincinci lidliwe.Ngezantsi ndiza kugxila kwindlela yesibini kwiinkcukacha zendlela yokubhala i-pcb ngokwefayile yoyilo.
Uyibhala njani iPCB
Zeziphi izinto ekufuneka zilungiselelwe:
ibhodi yesekethe (i-copper clad), ipeyinti yokutshiza (i-matte emnyama), ifayile yokuyila i-pcb, i-laser cutter, isisombululo se-ferric chloride (ukutshiza ubhedu), ukusula utywala (ukucoca), isisombululo sokuhlamba i-acetone (ukunyibilikisa ipeyinti), sandpaper ( ukupolisha ibhodi yobhedu)
Amanyathelo okusebenza:
1. Phatha ifayile yoyilo yePCB kwifayile yevektha (i-contour yangaphandle iya kufakwa ngelaser) kwaye uyilayishe kwinkqubo yelaser.
2. Akukho rhabaxa ibhodi efakwe ubhedu ngesandpaper, kwaye ucoce ubhedu kunye ne-alcohol yokuxubha okanye i-acetone, uqinisekise ukuba akukho mafutha kunye negrisi eseleyo.
3. Bamba ibhodi yesekethe kwipliers kwaye unike umzobo obhityileyo wokutshiza kuloo nto
4. Beka ibhodi yobhedu kwitafile yokusebenza kwaye uqale i-laser etching umzobo womphezulu
5. Emva kokucocwa, sula intsalela yepeyinti echotshiweyo usebenzisa utywala
6. Yibeke kwisisombululo se-PCB etchant (i-ferric chloride) ukutshiza ubhedu oluveziweyo.
7. Sombulula ipeyinti yesitshizi nge-acetone washing solvent (okanye isisusi sepeyinti esifana neXylene okanye ipeyinti encinci).Hlamba okanye usule ipeyinti emnyama eseleyo kwiibhodi ziyafikeleleka.
8. Gqoka imingxuma
9. Solder izinto zombane ngokusebenzisa imingxuma
10. Kugqityiwe
Kutheni ukhetha i-laser etching pcb
Kubalulekile ukuqaphela, ukuba umatshini we-CO2 we-laser ubeka ipeyinti yokutshiza phezulu ngokweendlela zesekethe endaweni yobhedu.Yindlela ehlakaniphile yokufaka ubhedu oluveziweyo kunye neendawo ezincinci kwaye zinokubulawa ekhaya.Kwakhona, i-laser cutter yamandla aphantsi iyakwazi ukuyenza ngenxa yokususwa ngokulula kwepeyinti yokutshiza.Ukufumaneka lula kwezinto kunye nokusebenza lula komatshini we-CO2 we-laser yenza indlela ethandwa kwaye ilula, ngaloo ndlela unokwenza i-pcb ekhaya, uchithe ixesha elincinci.Ngaphaya koko, iprototyping ekhawulezayo inokuqondwa yiCO2 laser ekrola ipcb, evumela uyilo lwe-pcbs olwahlukeneyo ukuba lulungiselelwe kwaye luphunyezwe ngokukhawuleza.Ngaphandle kokuguquguquka koyilo lwe-pcb, kukho umba ophambili malunga nokuba kutheni ukhethe i-co2 laser cutter ukuba ukuchaneka okuphezulu kunye ne-laser beam elungileyo iqinisekisa ukuchaneka koqhagamshelwano lwesekethe.
(Ingcaciso eyongezelelweyo - i-co2 laser cutter inamandla ekukroleni nasekufakeni kwizinto ezingezo zetsimbi. Ukuba udidekile kunye ne-laser cutter kunye ne-laser engraver, nceda ucofe ikhonkco ukuze ufunde ngakumbi:Umahluko: laser umkroli VS laser cutter |(mimowork.com)
CO2 laser pcb umatshini etching ilungele umaleko uphawu, umaleko kabini kunye nemigangatho ezininzi pcbs.Ungayisebenzisa ukuba diy uyilo pcb yakho ekhaya, kwaye kwakhona ubeke umatshini laser CO2 kwimveliso pcbs practical.Ukuphindaphinda okuphezulu kunye nokungaguquguquki kokuchaneka okuphezulu zizibonelelo ezibalaseleyo zokukrolwa kwelaser kunye nokukrolwa kwelaser, ukuqinisekisa umgangatho weprimiyamu yeePCB.Ulwazi oluneenkcukacha onokuthi ufumane kuloumkroli we-laser 100.
I-PCB yokupasa enye nge-laser ye-UV, i-fiber laser
Ngaphezu koko, ukuba ufuna ukuqonda ukusetyenzwa kwesantya esiphezulu kunye neenkqubo ezincinci zokwenza ii-pcbs, i-laser ye-UV, i-laser eluhlaza kunye nomatshini we-laser inokuba lukhetho olufanelekileyo.Ngokuthe ngqo kwe-laser etching ubhedu ukushiya umkhondo wesekethe inika uncedo olukhulu kwimveliso yemizi-mveliso.
✦ Uthotho lwamanqaku luya kuhlala luhlaziywa, unokufumana ngakumbi malunga nokusikwa kwe-UV laser kunye ne-laser etching kwiipcbs ngokulandelayo.
