I-Laser Etching PCB

(ibhodi lesifunda le-laser etching)

Ungayithola kanjani i-PCB etching ekhaya

Isingeniso esifushane sokunamathisela i-PCB nge-CO2 laser

Ngosizo lwe-CO2 laser cutter, imikhondo yesekethe embozwe upende wesifutho ingaqoshwa ngokunembile futhi ivezwe. Eqinisweni, i-CO2 laser ifaka upende kunethusi langempela. Uma upende usususiwe, ithusi eliveziwe livumela ukuqhutshwa kwesifunda okubushelelezi. Njengoba sazi, i-conductive medium - ibhodi eligqoke ithusi - lisiza ukuxhumanisa izingxenye ze-elekthronikhi kanye nokuqhutshwa kwesifunda. Umsebenzi wethu ukuveza ithusi ngokwefayela lokuklama le-PCB. Kule nqubo, sisebenzisa i-CO2 laser cutter yokushumeka kwe-PCB, eqondile futhi edinga izinto ezitholakala kalula. Ungahlola imiklamo ye-PCB yokudala ngokuzama lokhu ekhaya.

— Lungiselela

• Copper Clad Board • Sandpaper • PCB design file • CO2 laser cutter • Spray Paint • Ferric Chloride Solution • Alcohol Wipe • Acetone Washing Solution

- Ukwenza Izinyathelo (indlela yokuqopha i-PCB)

1. Phatha ifayela lokuklama le-PCB kufayela le-vector (ikhontatha 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

Kuyindlela ehlakaniphile yokufaka ithusi eliveziwe elinezindawo ezincane futhi lingabulawa ekhaya. Futhi, i-laser cutter enamandla aphansi ingayenza ngenxa yokususwa 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.

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 kuyo umqophi we-laser 100.

Ukuqagela okwengeziwe (ngokwereferensi kuphela)

Uma upende we-spray usebenza ukuze uvikele ithusi ukuthi lingagxili, ifilimu noma i-foil ingase ifinyeleleke ukuze ithathele upende njengendima efanayo. Ngaphansi kwesimo, sidinga kuphela ukucwengula ifilimu esikwe ngomshini we-laser okubonakala sengathi kulula kakhulu.

Noma yikuphi ukudideka nemibuzo mayelana nendlela yokwenza i-laser etch PCB

Xhumana nathi

Ungayifaka kanjani i-laser etching PCB ekukhiqizeni

I-laser ye-UV, i-laser eluhlaza, nomai-fiber laserzamukelwa kabanzi futhi zisizakala ngogongolo lwe-laser olunamandla amakhulu ukususa ithusi elingafuneki, lushiye iminonjana yethusi ngokuya ngamafayela okuklama anikeziwe. Asikho isidingo sopende, asikho isidingo se-etchant, inqubo ye-laser PCB etching iqedwa ngephasi eyodwa, kuncishiswe izinyathelo zokusebenza kanye nezindleko zokonga isikhathi nezindleko.

Uzuza ngogongolo lwe-laser oluhle kanye nesistimu yokulawula ikhompuyutha, umshini wokubhala we-laser PCB uphelelisa ikhono lokuxazulula inkinga. Ngaphezu kokunemba, akukho monakalo wemishini kanye nengcindezi endaweni engaphezulu ngenxa yokucubungula okuncane kokuxhumana kwenza i-laser etching igqame phakathi kwesigayo, izindlela zomzila.
