Yintoni iPCB?
I-PCB ibhekisa kwiBhodi yeSekethe eShicileleyo, engumthwali woqhagamshelo lombane lwamacandelo e-elektroniki kunye nenxalenye engundoqo yazo zonke iimveliso zombane.I-PCB ikwabizwa ngokuba yi-PWB (iBhodi yocingo oluShicileleyo).
Zeziphi iintlobo zezixhobo zePCB ezinokusikwa ngabasiki belaser?
Iintlobo zezixhobo zePCB ezinokusikwa ngumsiki welaser ochanekileyo ziquka iibhodi zesekethe ezisekelwe kwisinyithi, iibhodi zesekethe eziprintiweyo ezisekelwe kwiphepha, i-epoxy glass fiber eprinted circuit board, composite substrate eprinted circuit board, special substrate eprinted circuit boards kunye nezinye substrate. izixhobo.
IiPCB zephepha
Olu hlobo lwebhodi yesekethe eprintiweyo yenziwe ngephepha lefiber njengento yokuqinisa, ifakwe kwisisombululo se-resin (i-phenolic resin, i-epoxy resin) kwaye yomiswe, emva koko ifakwe ngeglue ye-copper electrolytic foil, kwaye icinezelwe phantsi kobushushu obuphezulu kunye noxinzelelo oluphezulu. .Ngokwemigangatho ye-ASTM/NEMA yaseMelika, ezona ndidi zingundoqo yi-FR-1, FR-2, FR-3 (ezi zingasentla ziyi-XPC e-flame retardant, XXXPC (ezi zingasentla azi-non-flame retardant) Ezona zisetyenziswa kakhulu kwaye zinkulu- imveliso isikali FR-1 kunye XPC eprintiweyo iibhodi sesekethe.
IiPCB zeFiberglass
Olu hlobo lwebhodi yesekethe eprintiweyo lusebenzisa i-epoxy okanye i-epoxy resin eguquliweyo njengesiseko sezinto zokunamathela, kunye nelaphu lefiber yeglasi njengento yokuqinisa.Ngoku iyeyona bhodi yesekethe inkulu eprintiweyo kwihlabathi kwaye lolona hlobo lusetyenziswayo lwebhodi yesekethe eprintiweyo.Kumgangatho we-ASTM/NEMA, kukho iimodeli ezine ze-epoxy fiberglass cloth: G10 (non-flame retardant), FR-4 (i-flame retardant).I-G11 (gcina amandla okushisa, kungekhona i-flame retardant), i-FR-5 (gcina amandla okushisa, i-flame retardant).Ngapha koko, iimveliso ezingezizo i-flame retardant ziyancipha unyaka nonyaka, kwaye i-FR-4 ibalelwa uninzi.
IiPCB ezihlanganisiweyo
Olu hlobo lwebhodi yesekethe eprintiweyo isekelwe ekusetyenzisweni kwezinto ezahlukeneyo zokuqinisa ukwenza izinto ezisisiseko kunye nezinto eziphambili.I-copper clad laminate substrates ezisetyenzisiweyo zizininzi ze-CEM series, phakathi kwazo i-CEM-1 kunye ne-CEM-3 zezona zimele kakhulu.Ilaphu lesiseko se-CEM-1 lilaphu lefiber yeglasi, izinto eziphambili liphepha, i-resin yi-epoxy, i-flame retardant.Ilaphu lesiseko se-CEM-3 lilaphu lefiber yeglasi, imathiriyeli engundoqo liphepha lefayibha yeglasi, iresin i-epoxy, i-flame retardant.Iimpawu ezisisiseko zebhodi yesekethe edibeneyo eprintiweyo ilingana ne-FR-4, kodwa ixabiso liphantsi, kwaye ukusebenza kwe-machining kungcono kune-FR-4.
IiPCB zentsimbi
I-Metal substrates (isiseko se-aluminiyam, isiseko sobhedu, isiseko sentsimbi okanye i-Invar steel) ingenziwa ibe yinye, kabini, iibhodi zesekethe eziprintiweyo ezininzi zentsimbi okanye iibhodi zesekethe ezingundoqo eziprintiweyo ngokweempawu zabo kunye nokusetyenziswa.
Isetyenziselwa ntoni iPCB?
I-PCB (ibhodi yesekethe eprintiweyo) isetyenziswa kubathengi be-elektroniki, izixhobo zoshishino, izixhobo zonyango, izixhobo zomlilo, izixhobo zokhuseleko kunye nezokhuseleko, izixhobo zonxibelelwano, ii-LED, izixhobo zemoto, izicelo zaselwandle, izixhobo ze-aerospace, ukukhusela kunye nezixhobo zomkhosi, kunye nezinye ezininzi. izicelo.Kwizicelo ezineemfuno eziphezulu zokhuseleko, ii-PCB kufuneka zihlangabezane nemigangatho yomgangatho ophezulu, ngoko ke kufuneka sizithathele ingqalelo zonke iinkcukacha zenkqubo yokuvelisa i-PCB.
Isebenza njani i-laser cutter kwiiPCBs?
Okokuqala, ukusika iPCB ngelaser kwahlukile ekusikeni ngoomatshini abanjengokugaya okanye ukunyathela.Ukusika kweLaser akuyi kushiya uthuli kwi-PCB, ngoko ke akuyi kuchaphazela ukusetyenziswa kwamva, kwaye uxinzelelo lomatshini kunye noxinzelelo lwe-thermal oluziswa yi-laser kumacandelo alunamsebenzi, kwaye inkqubo yokusika ithambile.
Ukongeza, itekhnoloji ye-laser inokuhlangabezana neemfuno zococeko.Abantu banokuvelisa i-PCB ngokucoceka okuphezulu kunye nomgangatho ophezulu ngokusebenzisa iteknoloji yokusika i-laser ye-STYLECNC ukunyanga izinto ezisisiseko ngaphandle kwe-carbonization kunye nokuguqulwa kwebala.Ukongeza, ukuze kuthintelwe ukungaphumeleli kwinkqubo yokusika, i-STYLECNC iye yenze noyilo oluhambelanayo kwiimveliso zayo ukuthintela.Ke ngoko, abasebenzisi banokufumana isivuno esiphezulu kakhulu kwimveliso.
Enyanisweni, nje ngokulungelelanisa iiparitha, umntu unokusebenzisa isixhobo esifanayo sokusika i-laser ukucubungula izinto ezahlukeneyo, ezifana nezicelo eziqhelekileyo (ezifana ne-FR4 okanye i-ceramics), i-substrates ye-metal insulated (IMS) kunye ne-system-in-packages (SIP).Oku kuguquguquka kwenza ukuba iiPCB zisetyenziswe kwiimeko ezahlukeneyo, ezifana nokupholisa okanye ukufudumeza iinkqubo zeenjini, i-chassis sensors.
Kuyilo lwePCB, akukho zithintelo kulwandlalo, iradiyasi, ileyibhile okanye eminye imiba.Ngokusikwa kwesangqa esipheleleyo, iPCB inokubekwa ngokuthe ngqo etafileni, ephucula kakhulu ukusebenza kakuhle kokusetyenziswa kwendawo.Ukusika iiPCB ngelaser kugcina izinto ezingaphezu kwe-30% xa kuthelekiswa neendlela zokusika ngoomatshini.Oku akuncedi nje ukunciphisa iindleko zokuvelisa iiPCB zenjongo ethile, kodwa kukwanceda nokwakha ubume bemekobume bendalo.
Iinkqubo zokusika ze-laser ze-STYLECNC zinokudibaniswa lula kunye neeNkqubo zokuSebenza zoMveliso ezikhoyo (MES).Inkqubo ye-laser ephezulu iqinisekisa ukuzinza kwenkqubo yokusebenza, ngelixa i-automatic feature yenkqubo nayo yenza lula inkqubo yokusebenza.Ngombulelo kumandla aphezulu omthombo we-laser odibeneyo, oomatshini be-laser banamhlanje bafaniswa ngokupheleleyo neenkqubo zoomatshini ngokwesantya sokusika.
Ngaphaya koko, iindleko zokusebenza kwenkqubo yelaser ziphantsi njengoko kungekho malungu anxitywayo afana neentloko zokusila.Iindleko zeendawo ezitshintshiweyo kunye nexesha lokuphumla okubangelwa koko kunokuphetshwa.
Zeziphi iindidi zabasiki belaser ezisetyenziselwa ukwenziwa kwePCB?
Kukho iintlobo ezintathu eziqhelekileyo zePCB abasiki laser ehlabathini.Unokwenza ukhetho olufanelekileyo ngokweemfuno zakho zoshishino lokwenziwa kwe-PCB.
I-CO2 Laser Cutters ye-Custom PCB Prototype
Umatshini wokusika we-CO2 we-laser usetyenziselwa ukusika ii-PCB ezenziwe ngezinto ezingezizo, njengephepha, i-fiberglass, kunye nezinye izinto ezidibeneyo.CO2 laser PCB cutters amaxabiso ukusuka $3,000 ukuya $12,000 ngokusekelwe iimpawu ezahlukeneyo.
Umatshini wokusika iFayibha yeLaser yePrototype yePCB eSiko
I-fiber laser cutter isetyenziselwa ukusika iiPCB ezenziwe ngezinto zetsimbi, ezifana ne-aluminiyam, ubhedu, intsimbi, kunye nentsimbi ye-Invar.
