Mapangidwe Amakonda kuchokera ku Laser Etching PCB
Monga gawo lofunikira pamagawo amagetsi, PCB (bolodi losindikizidwa) pakupanga ndi kupanga ndizovuta kwambiri kwa opanga zamagetsi.Mutha kudziwa zamaukadaulo osindikizira a pcb monga njira yosinthira tona ndipo ngakhale muzichita nokha.Apa ine ndikufuna kugawana nanu njira zina pcb etching ndi CO2 laser wodula, kukulolani flexibly makonda ma pcbs malinga ndi mapangidwe anu ankakonda.
Mfundo ndi njira ya pcb etching
- Mwachidule tchulani bolodi losindikizidwa
Mapangidwe osavuta a pcb amapangidwa ndi chosanjikiza chotchinga ndi zigawo ziwiri zamkuwa (zotchedwanso copper clad).Nthawi zambiri FR-4 (wolukidwa galasi ndi epoxy) ndi zinthu wamba kuti ntchito ngati kutchinjiriza, pakadali pano kutengera zofuna zosiyanasiyana pa ntchito inayake, kamangidwe dera, ndi makulidwe a bolodi, ma dielectrics ena monga FR-2 (phenolic thonje pepala), CEM-3 (galasi losalukidwa ndi epoxy) litha kutengedwanso.Chosanjikiza chamkuwa chimakhala ndi udindo wopereka chizindikiro chamagetsi kuti apange mgwirizano pakati pa zigawo kupyolera muzitsulo zotsekemera mothandizidwa ndi mabowo kapena pamwamba-phiri solder.Choncho, cholinga chachikulu etching pcb ndi kulenga kuda dera ndi mkuwa komanso kuthetsa mkuwa wopanda pake kapena kudzipatula kwa wina ndi mzake.
Kukhala ndi chiwongolero chachifupi pa pcb etching mfundo, timayang'ana njira wamba etching.Pali njira ziwiri zosiyana zogwiritsira ntchito potengera mfundo yofanana yoyika mkuwa wovala.
- Mayankho a PCB etching
Mmodzi ndi wa kuganiza kwachindunji komwe ndiko kuchotsa madera ena amkuwa opanda pake kupatula mayendedwe adera.Nthawi zambiri, timagwiritsa ntchito njira yopangira etching monga ferry chloride kuti tikwaniritse etching.Chifukwa cha madera akuluakulu omwe amayenera kukhazikitsidwa, nthawi yayitali iyenera kutengedwa komanso kuleza mtima kwakukulu.
Njira inansoyi imakhala mwanzeru kuti ikhale ndi mzere wodula (molondola molondola - kalembedwe ka madera ozungulira), zomwe zimapangitsa kuti gawo lenileni la mdera lizikhalapo polowa gulu la anthu osagwirizana.Munthawi imeneyi, mkuwa wocheperako umakhazikika ndipo nthawi yocheperako imadyedwa.M'munsimu ine kuganizira njira yachiwiri mwatsatanetsatane mmene etch a pcb malinga ndi kapangidwe wapamwamba.
Momwe mungayikitsire pcb
Zoyenera kukonzekera:
board board (copper cladboard), utoto wopopera (wakuda matte), pcb design file, laser cutter, ferric chloride solution (kuti etch copper), mowa pukuta (kuyeretsa), acetone kutsuka njira (kusungunula utoto), sandpaper ( kupukuta bolodi lamkuwa)
Njira zogwirira ntchito:
1. Gwirani fayilo ya mapangidwe a PCB ku fayilo ya vector (mzere wakunja udzakhala wokhazikika) ndikuyiyika mu makina a laser
2. Osapaka bolodi lovala zamkuwa ndi sandpaper, ndipo chotsani mkuwa ndi mowa wopaka kapena acetone, kuwonetsetsa kuti palibe mafuta ndi mafuta otsala.
3. Gwirani bolodi la dera mu pliers ndikupereka utoto wonyezimira wopoperapo
4. Ikani bolodi lamkuwa pa tebulo logwira ntchito ndikuyamba laser etching pamwamba penti
5. Pambuyo etching, pukutani utoto zotsalira anazikika ntchito mowa
6. Ikani mu PCB etchant solution (ferric chloride) kuti muyike mkuwa woonekera
7. Konzani utoto wopoperapo ndi zosungunulira zochapira acetone (kapena chochotsera utoto monga Xylene kapena chochepetsera utoto).Sambani kapena kupukuta otsala wakuda utoto pa matabwa ndi kufika.
8. Boolani mabowo
9. Solder zinthu zamagetsi kudzera m'mabowo
10. Anamaliza
Chifukwa kusankha laser etching pcb
Choyenera kudziwa, kuti makina a laser a CO2 amapaka utoto wopopera pamwamba potengera mayendedwe ozungulira m'malo mwa mkuwa.Ndi njira yochenjera yopangira mkuwa wowonekera ndi madera ang'onoang'ono ndipo ukhoza kuphedwa kunyumba.Komanso, chodula champhamvu chochepa cha laser chimatha kupanga chifukwa chochotsa mosavuta utoto wopopera.Kupezeka kosavuta kwa zida ndi kugwiritsa ntchito kosavuta kwa makina a laser CO2 kumapangitsa njirayo kukhala yotchuka komanso yosavuta, motero mutha kupanga pcb kunyumba, kuwononga nthawi yochepa.Komanso, prototyping mwamsanga akhoza anazindikira ndi CO2 laser chosema pcb, kulola zosiyanasiyana ma PC mapangidwe makonda ndi kudya anazindikira.Kupatula kusinthasintha kwa mapangidwe a pcb, pali chinthu chofunikira kwambiri chifukwa chosankha co2 laser cutter kuti kulondola kwakukulu ndi mtengo wabwino wa laser kumatsimikizira kulondola kwa kugwirizana kwa dera.
(Mafotokozedwe owonjezera - co2 laser cutter amatha kujambula ndi kukodza pazinthu zopanda zitsulo. Ngati mukusokonezedwa ndi chodula cha laser ndi chojambula cha laser, chonde dinani ulalo kuti mudziwe zambiri:The Kusiyana: laser engraver VS laser wodula |(mimowork.com)
CO2 laser pcb etching makina ndi oyenera wosanjikiza chizindikiro, zigawo ziwiri ndi zigawo zingapo ma PC.Mutha kugwiritsa ntchito kuti diy mamangidwe anu pcb kunyumba, komanso kuika makina CO2 laser mu kuchita pcbs kupanga.Kubwerezanso kwambiri komanso kusasinthika kolondola kwambiri ndi zabwino kwambiri pakujambula kwa laser ndi kujambula kwa laser, kuonetsetsa kuti ma PCB apamwamba kwambiri.Zambiri zoti mutengelaser chojambula 100.
Kuyika kwa PCB imodzi ndi UV laser, fiber laser
Kuonjezera apo, ngati mukufuna kuzindikira makonzedwe othamanga kwambiri komanso njira zochepa zopangira ma pcbs, laser UV, laser yobiriwira ndi makina a laser akhoza kukhala zosankha zabwino.Mwachindunji laser etching mkuwa kusiya kutsata dera amapereka mwayi waukulu kupanga mafakitale.
✦ Mndandanda wa nkhani adzapitiriza kusinthidwa, mukhoza kupeza zambiri za UV laser kudula ndi laser etching pa pcbs lotsatira.
Mwachindunji kuwombera ife imelo ngati mukufuna njira laser kuti pcb etching
