Iyini i-PCB?
I-PCB ibhekisele ku-Printed Circuit Board, okuwumthwali wokuxhunywa kukagesi wezingxenye ze-elekthronikhi kanye nengxenye ewumongo yayo yonke imikhiqizo kagesi. I-PCB yaziwa nangokuthi PWB (Printed Wire Board).
Yiziphi izinhlobo zezinto ze-PCB ezingasikwa ngabasiki be-laser?
Izinhlobo zezinto ze-PCB ezingasikwa ngomsiki we-laser onembile zihlanganisa amabhodi wesifunda asekelwe ensimbi, amabhodi wesifunda asekelwe ephepheni, amabhodi esifunda e-epoxy glass fiber, amabhodi wesifunda aphrintiwe ahlanganisiwe, amabhodi esifunda aphrintiwe akhethekile kanye nenye i-substrate. izinto zokwakha.
Ama-PCB wephepha
Lolu hlobo lwebhodi lesifunda eliphrintiwe lenziwe nge-fiber paper njengento yokuqinisa, efakwe kwisisombululo se-resin (phenolic resin, epoxy resin) futhi yomisiwe, bese imbozwa nge-glue-coated electrolytic foil yethusi, futhi icindezelwe ngaphansi kwezinga lokushisa eliphezulu nokucindezela okukhulu. . Ngokwamazinga e-American ASTM/NEMA, izinhlobonhlobo eziyinhloko yi-FR-1, FR-2, FR-3 (okungenhla kuyi-XPC e-flame retardant, XXXPC (okungenhla ayi-non-flame retardant). Esetshenziswa kakhulu futhi inkulu- ukukhiqizwa kwesikali kukhona amabhodi esekethe e-FR-1 kanye ne-XPC.
Ama-PCB we-Fiberglass
Lolu hlobo lwebhodi lesifunda eliphrintiwe lisebenzisa i-epoxy noma i-epoxy resin eguquliwe njengesisekelo sezinto zokunamathisela, kanye nendwangu yengilazi yefiber njengento eqinisayo. Njengamanje iyibhodi lesifunda eliphrintiwe elikhulu kunawo wonke emhlabeni futhi iwuhlobo olusetshenziswa kakhulu lwebhodi lesifunda eliphrintiwe. Kuzinga le-ASTM/NEMA, kunamamodeli amane endwangu ye-epoxy fiberglass: G10 (non-flame retardant), FR-4 (flame retardant). I-G11 (gcina amandla okushisa, hhayi i-flame retardant), FR-5 (gcina amandla okushisa, i-flame retardant). Eqinisweni, imikhiqizo engeyona i-flame retardant iyancipha unyaka nonyaka, futhi i-FR-4 ilandisa ngobuningi.
Ama-PCB ahlanganisiwe
Lolu hlobo lwebhodi lesifunda eliphrintiwe lusekelwe ekusetshenzisweni kwezinto zokuqinisa ezihlukene ukuze kwakhiwe izinto eziyisisekelo kanye nezinto eziyinhloko. Ama-substrates ane-copper clad laminate asetshenziswayo ikakhulukazi uchungechunge lwe-CEM, phakathi kwawo i-CEM-1 ne-CEM-3 ezimele kakhulu. Indwangu eyisisekelo ye-CEM-1 iyindwangu ye-fiber yengilazi, i-core material iyiphepha, i-resin i-epoxy, i-flame retardant. Indwangu eyisisekelo ye-CEM-3 iyindwangu ye-fiber yengilazi, i-core material iyi-glass fiber paper, i-resin i-epoxy, i-flame retardant. Izici eziyisisekelo zebhodi lesifunda eliphrintiwe eliyisisekelo elihlanganisiwe zilingana ne-FR-4, kodwa izindleko ziphansi, futhi ukusebenza komshini kungcono kune-FR-4.
Ama-PCB ensimbi
Ama-Metal substrates (isisekelo se-aluminium, isisekelo sethusi, isisekelo sensimbi noma insimbi ye-Invar) angenziwa abe amabhodi wesekethe, aphindwe kabili, anezingqimba eziningi zensimbi noma amabhodi esekethe aphrintiwe ensimbi ngokwezici zawo kanye nokusetshenziswa kwawo.
Isetshenziselwa ini i-PCB?
I-PCB (ibhodi lesifunda eliphrintiwe) isetshenziswa kuma-electronics abathengi, okokusebenza kwezimboni, ezinsizakalweni zezokwelapha, okokusebenza komlilo, okokuvikela nokokuvikela, okokusebenza ngocingo, ama-LED, izingxenye zezimoto, izinhlelo zokusebenza zasolwandle, izingxenye ze-aerospace, ezokuvikela nezempi, kanye nezinye eziningi. izicelo. Ezicelweni ezinezidingo zokuphepha eziphezulu, ama-PCB kumele ahlangabezane nezindinganiso zekhwalithi ephezulu, ngakho-ke kufanele sithathe yonke imininingwane yenqubo yokukhiqiza ye-PCB ngokungathi sína.
Isebenza kanjani i-laser cutter kuma-PCB?
Okokuqala, ukusika i-PCB nge-laser kuhlukile ekusikeni ngemishini efana nokugaya noma ukugxiviza. Ukusika i-laser ngeke kushiye uthuli ku-PCB, ngakho-ke ngeke kuthinte ukusetshenziswa kwakamuva, futhi ukucindezeleka komshini nokucindezeleka okushisayo okwethulwa yi-laser ezingxenyeni akunakwa, futhi inqubo yokusika imnene impela.
Ngaphezu kwalokho, ubuchwepheshe be-laser bungahlangabezana nezidingo zokuhlanzeka. Abantu bangakhiqiza i-PCB ngokuhlanzeka okuphezulu kanye nekhwalithi ephezulu ngokusebenzisa ubuchwepheshe bokusika be-laser be-STYLECNC ukuphatha izinto eziyisisekelo ngaphandle kwe-carbonization kanye nokushintsha umbala. Ngaphezu kwalokho, ukuze kuvinjelwe ukwehluleka enqubweni yokusika, i-STYLECNC iphinde yenza imiklamo ehlobene emikhiqizweni yayo ukuze ivimbele. Ngakho-ke, abasebenzisi bangathola izinga eliphezulu kakhulu lokukhiqiza ekukhiqizeni.
Eqinisweni, ngokulungisa nje amapharamitha, umuntu angasebenzisa ithuluzi elifanayo lokusika i-laser ukucubungula izinto ezihlukahlukene, njengezinhlelo zokusebenza ezijwayelekile (ezifana ne-FR4 noma i-ceramics), ama-substrates ensimbi e-insulated (IMS) kanye ne-system-in-packages (SIP). Lokhu kuvumelana nezimo kwenza ama-PCB asetshenziswe ezimeni ezihlukahlukene, njengokupholisa noma amasistimu okushisa ezinjini, izinzwa ze-chassis.
Ekwakhekeni kwe-PCB, akukho mikhawulo kuhlaka, irediyasi, ilebula noma ezinye izici. Ngokusika umbuthano ogcwele, i-PCB ingabekwa etafuleni ngqo, okuthuthukisa kakhulu ukusebenza kahle kokusetshenziswa kwesikhala. Ukusika ama-PCB ngelaser kusindisa izinto ezingaphezu kuka-30% uma kuqhathaniswa namasu okusika imishini. Lokhu akusizi nje kuphela ukunciphisa izindleko zokukhiqiza ama-PCB enhloso ethile, kodwa futhi kusiza ukwakha indawo ezungezile enobungani.
Amasistimu wokusika we-laser we-STYLECNC angahlanganiswa kalula nama-Manufacturing Execution Systems (MES) akhona. Uhlelo lwe-laser oluthuthukisiwe luqinisekisa ukuzinza kwenqubo yokusebenza, kuyilapho isici esizenzakalelayo sohlelo senza inqubo yokusebenza ibe lula. Ngenxa yamandla aphezulu omthombo we-laser odidiyelwe, imishini ye-laser yanamuhla iqhathaniswa ngokugcwele nezinhlelo zemishini ngokwejubane lokusika.
Ngaphezu kwalokho, izindleko zokusebenza kohlelo lwe-laser ziphansi njengoba zingekho izingxenye ezigqokiwe ezifana namakhanda okugaya. Izindleko zokushintshwa kwezingxenye kanye nesikhathi sokuphumula esiwumphumela singagwenywa.
Yiziphi izinhlobo zabasiki be-laser ezisetshenziselwa ukwenziwa kwe-PCB?
Kunezinhlobo ezintathu ezivame kakhulu zokusika i-PCB laser emhlabeni. Ungenza ukukhetha okufanele ngokuya ngezidingo zakho zebhizinisi lokwenziwa kwe-PCB.
