Kapangidwe Kapadera kuchokera ku Laser Etching PCB
Monga gawo lofunika kwambiri pazigawo zamagetsi, PCB (bolodi yosindikizidwa) yopangira ndi kupanga ndi nkhani yaikulu kwa opanga zamagetsi. Mutha kudziwa bwino ukadaulo wachikhalidwe wosindikiza wa pcb monga njira yosamutsira toner ndipo mumachita nokha. Pano ndikufuna kugawana nanu njira zina zolembera pcb pogwiritsa ntchito chodulira laser cha CO2, zomwe zimakulolani kusintha mosavuta ma pcb malinga ndi mapangidwe omwe mumakonda.
Mfundo ndi njira yopangira pcb etching
- Fotokozani mwachidule bolodi losindikizidwa la dera
Kapangidwe kosavuta ka pcb kamapangidwa ndi wosanjikiza woteteza ndi zigawo ziwiri zamkuwa (zomwe zimatchedwanso mkuwa wophimba). Nthawi zambiri FR-4 (galasi lolukidwa ndi epoxy) ndiye chinthu chofala chomwe chimagwiritsidwa ntchito ngati chotetezera, pakadali pano kutengera zofunikira zosiyanasiyana pa ntchito zinazake, mapangidwe a circuit, ndi kukula kwa bolodi, ma dielectric ena monga FR-2 (phenolic thonje paper), CEM-3 (galasi losalukidwa ndi epoxy) amathanso kugwiritsidwa ntchito. Wosanjikiza wamkuwa umatenga udindo wopereka chizindikiro chamagetsi kuti apange kulumikizana pakati pa zigawo kudzera mu zigawo zotetezera pogwiritsa ntchito mabowo odutsa kapena solder yoyika pamwamba. Chifukwa chake, cholinga chachikulu cha etching pcb ndikupanga ma circuit traces ndi mkuwa komanso kuchotsa mkuwa wopanda ntchito kapena kuwapangitsa kukhala osiyana.
Pokhala ndi chithunzithunzi chachidule cha mfundo yopangira pcb, tayang'ana njira zogwiritsira ntchito zopangira. Pali njira ziwiri zosiyana zogwiritsira ntchito pogwiritsa ntchito mfundo imodzi yopangira mkuwa wophimbidwa.
- Mayankho okongoletsa a PCB
Limodzi ndi la kuganiza mwachindunji komwe ndi kuchotsa madera ena onse opanda ntchito a mkuwa kupatulapo mizere yozungulira. Nthawi zambiri, timagwiritsa ntchito njira yopangira zinthu monga ferry chloride kuti tikwaniritse njira yopangira zinthu. Chifukwa cha madera akuluakulu oti apangidwe, nthawi yayitali imafunika komanso kuleza mtima kwakukulu.
Njira ina ndi yanzeru kwambiri yodula mzere wodulidwa (monga momwe zilili - mawonekedwe a dongosolo la dera), zomwe zimapangitsa kuti dera liziyenda bwino pamene likulekanitsa gulu la mkuwa losafunikira. Pachifukwa ichi, mkuwa wochepa umadulidwa ndipo nthawi yochepa imatengedwa. Pansipa ndiyang'ana kwambiri njira yachiwiri yofotokozera mwatsatanetsatane momwe mungadulire pcb malinga ndi fayilo yopangidwa.
Momwe mungalembe pcb
Zinthu zokonzekera:
bolodi la dera (bolodi la mkuwa), utoto wopopera (wakuda wosawoneka bwino), fayilo ya kapangidwe ka pcb, chodulira cha laser, yankho la ferric chloride (lopaka mkuwa), chopukutira mowa (choyeretsa), yankho la acetone (losungunula utoto), sandpaper (yopukutira bolodi la mkuwa)
Masitepe Ogwirira Ntchito:
1. Gwirani fayilo ya kapangidwe ka PCB kukhala fayilo ya vekitala (mawonekedwe akunja adzajambulidwa ndi laser) ndikuyiyika mu dongosolo la laser
2. Musamange bolodi lokhala ndi mkuwa ndi sandpaper, ndipo yeretsani mkuwa ndi rubbing alcohol kapena acetone, kuonetsetsa kuti palibe mafuta ndi mafuta otsala.
3. Gwirani bolodi lamagetsi mu pliers ndikujambula pang'ono pa izo
4. Ikani bolodi lamkuwa patebulo logwirira ntchito ndikuyamba kujambula pamwamba pogwiritsa ntchito laser
5. Mukamaliza kupukuta, pukutani zotsalira za utoto wopukuta pogwiritsa ntchito mowa
6. Ikani mu PCB etchant solution (ferric chloride) kuti muphwanye mkuwa wowonekera
7. Thirani utoto wopopera ndi acetone washing solvent (kapena chochotsera utoto monga Xylene kapena utoto wothina). Sambitsani kapena pukutani utoto wakuda wotsalawo kuchokera pa bolodi.
8. Boolani mabowo
9. Soldering elements zamagetsi kudzera m'mabowo
10. Yatha
Chifukwa chiyani mungasankhe laser etching pcb
Chofunika kudziwa ndi chakuti makina a CO2 laser amajambula utoto wopopera pamwamba pa nthaka motsatira mizere ya circuit m'malo mwa mkuwa. Ndi njira yanzeru yojambula mkuwa wowonekera ndi malo ang'onoang'ono ndipo ukhoza kuchitidwa kunyumba. Komanso, chodulira cha laser chotsika mphamvu chimatha kuchipanga chifukwa cha utoto wopopera mosavuta. Kupezeka mosavuta kwa zipangizo komanso kugwiritsa ntchito mosavuta makina a CO2 laser kumapangitsa kuti njirayi ikhale yotchuka komanso yosavuta, motero mutha kupanga pcb kunyumba, mutakhala nthawi yochepa. Kuphatikiza apo, kupanga prototyping mwachangu kumatha kuchitika ndi CO2 laser engraving pcb, zomwe zimathandiza kuti mapangidwe osiyanasiyana a pcb asinthidwe ndikudziwika mwachangu. Kupatula kusinthasintha kwa kapangidwe ka pcb, pali chinthu chofunikira chokhudza chifukwa chake muyenera kusankha chodulira cha CO2 laser kuti kulondola kwambiri ndi kuwala kwa laser kosalala kumatsimikizira kulondola kwa kulumikizana kwa circuit.
(Kufotokozera kwina - co2 laser cutter ili ndi luso lolemba ndi kulemba zinthu zosakhala zachitsulo. Ngati mukusokonezeka ndi laser cutter ndi laser engraver, chonde dinani ulalo kuti mudziwe zambiri:Kusiyana: chojambula cha laser VS chodulira laser | (mimowork.com)
Makina ojambulira a CO2 laser pcb ndi oyenera kupanga ma signal layer, ma double layers ndi ma PCB angapo. Mutha kugwiritsa ntchito kupanga ma PCB anu kunyumba, komanso kuyika makina a CO2 laser mu ma PCB othandiza. Kubwerezabwereza kwambiri komanso kusinthasintha kwa kulondola kwambiri ndi zabwino kwambiri pakujambula ndi laser, kuonetsetsa kuti ma PCB ndi abwino kwambiri. Zambiri mwatsatanetsatane kuti mupeze kuchokerachosema cha laser 100.
Kujambula kwa PCB kamodzi kokha ndi laser ya UV, laser ya fiber
Komanso, ngati mukufuna kupanga zinthu mwachangu komanso njira zochepa zopangira ma PCB, UV laser, green laser ndi fiber laser makina akhoza kukhala chisankho chabwino. Kujambula mkuwa mwachindunji ndi laser kuti musiye ma circuit traces kumapereka mwayi wabwino kwambiri popanga mafakitale.
✦ Nkhani zingapo zipitiliza kusinthidwa, mutha kupeza zambiri zokhudza kudula kwa laser ya UV ndi kudula kwa laser pa ma PCB mtsogolomu.
Titumizireni imelo mwachindunji ngati mukufuna njira ya laser yothetsera pcb etching
Kodi ndife ndani?
Mimowork ndi kampani yoganizira zotsatira zomwe imabweretsa ukatswiri wazaka 20 wochita zinthu mozama kuti ipereke mayankho opangira laser ndi kupanga kwa mabizinesi ang'onoang'ono ndi apakatikati (mabizinesi ang'onoang'ono ndi apakatikati) mkati ndi pafupi ndi zovala, magalimoto, ndi malo otsatsa malonda.
Chidziwitso chathu chochuluka cha njira zothetsera mavuto pogwiritsa ntchito laser chomwe chimachokera kwambiri mu malonda, magalimoto ndi ndege, mafashoni ndi zovala, kusindikiza kwa digito, ndi mafakitale a nsalu zosefera zimatithandiza kufulumizitsa bizinesi yanu kuyambira pa njira mpaka kuchita tsiku ndi tsiku.
