Igishushanyo cyihariye gikozwe muri PCB yo gushushanya hakoreshejwe laser
Nk'igice cy'ingenzi mu bice by'ikoranabuhanga, PCB (ikibaho cyo gushushanya no gukora) cyo gushushanya no gukora ni ikibazo gikomeye ku bakora ibikoresho by'ikoranabuhanga. Ushobora kuba uzi ikoranabuhanga risanzwe ryo gucapa pcb nk'uburyo bwo kohereza toner ndetse ukaba wanabikora wenyine. Aha ndashaka gusangira nawe ubundi buryo bwo gushushanya pcb ukoresheje icyuma gikata laser cya CO2, kigufasha guhindura pcb mu buryo bworoshye ukurikije imiterere wifuza.
Ihame n'ubuhanga bwo gushushanya pcb
- Tanga muri make urubuga rwanditseho circuit board
Igishushanyo mbonera cyoroheje cya pcb gikora mu buryo bworoshye bw’urwego rukingira ubushyuhe n’ibice bibiri by’umuringa (byitwa kandi umuringa upfutse). Ubusanzwe FR-4 (ikirahure gikozwe mu irahure na epoxy) ni byo bikoresho bisanzwe bikoreshwa mu gukingira ubushyuhe, hagati aho hashingiwe ku bisabwa bitandukanye ku mikorere yihariye, imiterere y’urusobe rw’amashanyarazi, n’ingano z’urusobe rw’amashanyarazi, bimwe mu bikoresho nka FR-2 (impapuro z’ipamba za phenolic), CEM-3 (ikirahure kidakozwe mu irahure na epoxy) nabyo bishobora gukoreshwa. Urusobe rw’umuringa rufata inshingano zo gutanga ikimenyetso cy’amashanyarazi kugira ngo hubakwe isano hagati y’ibice binyuze mu bice bikingira ubushyuhe hifashishijwe imyobo cyangwa isudira yo gushyira hejuru. Kubwibyo, intego nyamukuru yo gukata pcb ni ugukora uduce tw’urusobe rw’amashanyarazi hakoreshejwe umuringa ndetse no gukuraho umuringa udafite akamaro cyangwa gutuma utandukana.
Dufite isomo rigufi ku ihame ryo gukata icyuma cya PCB, turareba uburyo busanzwe bwo gukata icyuma. Hari uburyo bubiri butandukanye bwo gukora bushingiye ku ihame rimwe ryo gukata icyuma cyambaye ubusa.
- Ibisubizo byo gushushanya PCB
Umuntu agamije gutekereza mu buryo butaziguye, ari byo gukuraho ibice bisigaye by'umuringa udafite akamaro uretse uduce duto tw'uruziga. Ubusanzwe, dukoresha umuti wo gukata nka feri ya chloride kugira ngo tugere ku gikorwa cyo gukata. Kubera ko ahantu hanini hagomba gukata, hagomba gufatwa igihe kirekire ndetse no kwihangana gukomeye.
Ubundi buryo ni ubuhanga cyane mu gukata umurongo waciwe (tuvuge neza - imiterere y'uruziga), biganisha ku gukata neza uruziga mu gihe utandukanya agace k'umuringa kadafite aho gahuriye n'icyo gikoresho. Muri ubu buryo, umuringa muke uracukurwa kandi igihe gito kirakoreshwa. Hasi ndibanda ku buryo bwa kabiri bwo gusobanura uburyo bwo gukata icyuma cya PCB hakurikijwe dosiye y'igishushanyo.
Uburyo bwo gukata PCB
Ibintu byo kwitegura:
ikibaho cy'uruziga (urubaho rw'umuringa), irangi ry'umukara (umukara udapfundikiye), dosiye y'igishushanyo cya pcb, icyuma gikata laser, umuti wa ferric chloride (wo gukata umuringa), ihanagura rya alcohol (ryo gusukura), umuti wo kumesa acetone (wo gushonga irangi), urupapuro rwo gusiga (rwo gusiga irangi ku rubaho rw'umuringa)
Intambwe z'imikorere:
1. Fata dosiye y'igishushanyo cya PCB uyishyire kuri dosiye ya vektori (inyuma y'igishushanyo mbonera igiye gukatwaho inyuguti za laser) hanyuma uyishyire muri sisitemu ya laser
2. Ntukarunge urubaho rw'umuringa n'umusenyi, kandi usukure umuringa ukoresheje inzoga cyangwa asetone, urebe neza ko nta mavuta n'amavuta bisigaye.
3. Fata ikibaho cy'uruziga mu gikoresho hanyuma ushyireho irangi rito kuri icyo
4. Shyira ikibaho cy'umuringa ku meza yo gukoreraho hanyuma utangire gushushanya ubuso hakoreshejwe laser
5. Nyuma yo gukata, kuraho ibisigazwa by'irangi ryacitse ukoresheje alcool
6. Shyira mu gikoresho cya PCB (ferric chloride) kugira ngo ucukure umuringa wagaragaye
7. Shyira irangi ry'umusemburo ukoresheje acetone woza (cyangwa imashini ikuraho irangi nka Xylene cyangwa irangi rigabanya irangi). Oga cyangwa uhanagure irangi ry'umukara risigaye ku mbaho.
8. Gucukura imyobo
9. Gusogota ibikoresho by'ikoranabuhanga binyuze mu mwobo
10. Byarangiye
Kuki wahitamo pcb ikoresha laser etching
Icyitonderwa ni uko imashini ya CO2 laser ikuraho irangi ryo gusukura hejuru hakurikijwe imirongo y’uruziga aho gukoresha umuringa. Ni uburyo bwiza bwo gushushanya umuringa wagaragaye ukoresheje uduce duto kandi ushobora gukoreshwa mu rugo. Nanone, gukata laser gafite imbaraga nkeya bishobora kubikora bitewe nuko irangi ryo gusukura ryoroshye. Kuba ibikoresho byoroshye kubona no gukoresha CO2 laser bituma uburyo bukundwa kandi bworoshye, bityo ushobora gukora PCB mu rugo, ukamara igihe gito. Byongeye kandi, gushushanya byihuse bishobora gukorwa na CO2 laser engraving PCB, bigatuma imiterere itandukanye ya PCB ihindurwa kandi ikamenyekana vuba. Uretse ko imiterere ya PCB ihinduka, hari ikintu cy'ingenzi ku mpamvu yo guhitamo co2 laser cutter ko ikoranabuhanga rihanitse hamwe n’imirasire myiza ya laser bitanga icyizere cy’uko uruziga ruhuza neza.
(Ibisobanuro by'inyongera - co2 laser cutter ifite ubushobozi bwo gushushanya no gushushanya ku bikoresho bitari icyuma. Niba witiranyije na laser cutter n'icyuma gishushanya, kanda kuri iyi link kugira ngo umenye byinshi:Itandukaniro: icyuma gikata laser VS icyuma gikata laser | (mimowork.com)
Imashini yo gushushanya CO2 laser PCB ikwiriye urwego rw'ibimenyetso, urwego rubiri n'urwego rwinshi rwa PCB. Ushobora kuyikoresha mu gukora igishushanyo cya PCB yawe mu rugo, kandi ugashyira imashini ya CO2 laser mu bikorwa bya PCB. Ishobora gusubiramo byinshi kandi ikagira ubuziranenge bwinshi ni inyungu nziza zo gushushanya laser no gushushanya laser, bigatuma PCB zikora neza cyane. Amakuru arambuye yo kuvana kuriicyuma gishushanya hakoreshejwe laser 100.
Gushushanya PCB rimwe hakoreshejwe laser ya UV, laser ya fiber
