Dhizaini Yakagadzirwa NeLaser Etching PCB
Sechinhu chakakosha muzvikamu zvemagetsi, PCB (bhodhi redunhu rakadhindwa) rekugadzira nekugadzira chinhu chinonyanya kukosha kune vagadziri vemagetsi. Ungave uchiziva matekinoroji echinyakare ekudhinda ePCB senge nzira yekutumira toner uye unotoishandisa wega. Pano ndinoda kugovera nemi dzimwe nzira dzekucheka dzePCB neCO2 laser cutter, zvichikubvumidza kugadzirisa maPCB zvinoenderana nemagadzirirwo aunoda.
Nheyo uye nzira yekunyora pcb
- Taura muchidimbu nezvebhodhi redunhu rakadhindwa
Dhizaini yepcb iri nyore inogadzirwa nechikamu chinodziisa simba uye zvikamu zviviri zvemhangura (zvinonziwo copper clad). Kazhinji FR-4 (girazi rakarukwa uye epoxy) ndiyo chinhu chinowanzo shandiswa sechidziisa simba, panguva imwe chete zvichibva pane zvinodiwa zvakasiyana-siyana pamabasa chaiwo, magadzirirwo edunhu, uye saizi dzemabhodhi, mamwe ma dielectric akadai seFR-2 (phenolic cotton paper), CEM-3 (girazi risiri rakarukwa uye epoxy) anogonawo kushandiswa. Chikamu chemhangura chinotora mutoro wekupa chiratidzo chemagetsi kuti chigadzire kubatana pakati pezvikamu kuburikidza nezvikamu zvinodziisa simba nerubatsiro rwemaburi anopinza kana solder inosungirirwa pamusoro. Nokudaro, chinangwa chikuru chekucheka pcb kugadzira maronda edunhu nemhangura pamwe nekubvisa mhangura isina basa kana kuita kuti aparadzane.
Tichitarisa zvishoma nezvepfungwa yekucheka kwePCB, tinoongorora nzira dzakajairika dzekucheka. Kune nzira mbiri dzakasiyana dzekushandisa dzakavakirwa papfungwa imwe chete yekucheka mhangura yakaputirwa.
- Mhinduro dzePCB dzekucheka
Imwe ndeyekufunga zvakananga kubvisa nzvimbo dzese dzemhangura dzisina basa kunze kwenzvimbo dzakatarwa. Kazhinji, tinoshandisa mushonga wekucheka wakaita seferry chloride kuti tiwane nzira yekucheka. Nekuda kwenzvimbo dzakakura dzinofanira kuchekwa, nguva yakareba inoda kutorwa pamwe nemoyo murefu.
Imwe nzira ndeyekuchenjera kucheka mutsetse wakachekwa (taurai nemazvo - chimiro chedenderedzwa), zvichitungamira pakufambiswa kwedenderedzwa kwakanyatsojeka uku uchibvisa panel yemhangura isina basa. Mumamiriro ezvinhu aya, mhangura shoma inochekwa uye nguva shoma inopedzwa. Pasi apa ndichatarisa nzira yechipiri yekutsanangura manyorerwo ekucheka pcb zvichienderana nefaira rekugadzira.
Maitiro ekucheka PCB
Zvinhu zvekugadzirira:
bhodhi redunhu (bhodhi remhangura), pendi yespray (nhema isina kupfapfaidzwa), faira rekugadzira pcb, laser cutter, ferric chloride solution (yekucheka mhangura), alcohol wipe (yekuchenesa), acetone washing solution (yekunyungudutsa pendi), sandpaper (yekupukuta bhodhi remhangura)
Matanho Ekushanda:
1. Bata faira rePCB rekugadzira faira kune faira revector (mufananidzo wekunze uchachekwa nelaser) woriisa musystem yelaser
2. Usakwesha bhodhi rakaputirwa nemhangura nesandpaper, wobva wachenesa mhangura nerubbing alcohol kana acetone, uchiita shuwa kuti hapana mafuta nemafuta zvasara.
3. Bata bhodhi redunhu mupliers wobva wapenda pendi yakapfapfaidza pariri
4. Isa bhodhi remhangura patafura yekushanda wotanga kupenda pamusoro nelaser
5. Mushure mekutema, pukutai zvasara zvependi yakatema uchishandisa doro
6. Isa muPCB etchant solution (ferric chloride) kuti ucheke mhangura yakafumurwa
7. Pedzisa pendi yekupfapfaidza neacetone washing solvent (kana chinobvisa pendi senge Xylene kana pendi thinner). Geza kana kupukuta pendi nhema yasara kubva pamabhodhi.
8. Boora maburi
9. Solder zvinhu zvemagetsi nepaburi
10. Yapera
Sei uchifanira kusarudza laser etching pcb
Zvakakosha kuziva kuti muchina weCO2 laser unocheka pendi yekupfapfaidza pamusoro zvichienderana nemasaiti edunhu panzvimbo pemhangura. Inzira yakangwara yekucheka mhangura yakaratidzwa nenzvimbo diki uye inogona kuitwa kumba. Zvakare, muchina wekucheka laser une simba shoma unokwanisa kuzviita nekuda kwekubvisa pendi yekupfapfaidza zviri nyore. Kuwanikwa kuri nyore kwezvinhu uye kushanda kuri nyore kwemuchina weCO2 laser kunoita kuti nzira iyi ive yakakurumbira uye iri nyore, saka unogona kugadzira pcb kumba, uchishandisa nguva shoma. Uyezve, kukurumidza kugadzira prototyping kunogona kuitwa neCO2 laser engraving pcb, zvichibvumira magadzirirwo akasiyana-siyana epcb kuti agadziriswe uye aonekwe nekukurumidza. Kunze kwekuchinjika kwekugadzirwa kwepcb, pane chinhu chakakosha pamusoro pekuti sei uchifanira kusarudza co2 laser cutter kuti kunyatsoita nemwaranzi welaser wakanaka kunovimbisa kururama kwekubatana kwedunhu.
(Tsananguro yakawedzerwa - co2 laser cutter ine hunyanzvi mukunyora nekunyora zvinhu zvisiri zvesimbi. Kana uchivhiringidzika ne laser cutter ne laser engraver, ndapota tinya link kuti udzidze zvakawanda:Musiyano: muvezi welaser VS mucheki welaser | (mimowork.com)
Muchina weCO2 laser pcb etching wakakodzera masaini ekuisa, machira maviri uye machira akawanda epcb. Unogona kuushandisa kugadzira dhizaini yako yepcb kumba, uye zvakare kuisa muchina weCO2 laser mukugadzirwa kwepcb. Kudzokororwa kwakanyanya uye kugadzikana kwehunyanzvi hwepamusoro zvakanakira laser etching uye laser engraving, zvichivimbisa mhando yepamusoro yePCB. Ruzivo rwakadzama rwekuwana kubvamuvezi welaser 100.
Kucheka kwePCB imwe chete kuburikidza neUV laser, fiber laser
Uyezve, kana uchida kugadzira nekukasira uye nzira shoma dzekugadzira maPCB, UV laser, green laser uye fiber laser muchina ingave sarudzo dzakanaka. Kucheka mhangura zvakananga nelaser kuti usiye macircuit traces kunoita kuti zvive nyore kugadzira maindasitiri.
✦ Nyaya dzakatevedzana dzicharamba dzichivandudzwa, unogona kuwana zvakawanda nezvekucheka kweUV laser uye laser etching paPCBs mune inotevera.
