Iyini i-PCB?
I-PCB ibhekisele ku-Printed Circuit Board, okuwumthwali wokuxhunywa kukagesi wezingxenye ze-elekthronikhi kanye nengxenye ewumongo yayo yonke imikhiqizo kagesi. PCB yaziwa nangokuthi PWB (Printed Wire Board).
Yiziphi izinhlobo zezinto ze-PCB ezingasikwa ngabasiki be-laser?
Izinhlobo zezinto ze-PCB ezingasikwa a ukunemba laser umsiki zihlanganisa amabhodi wesifunda aphrintiwe asekelwe ensimbi, amabhodi wesifunda asekelwe ephepheni, amabhodi wesifunda epoxy glass fiber aphrintiwe, amabhodi wesifunda aphrintiwe we-substrate, amabhodi wesifunda aphrintiwe we-substrate akhethekile nezinye izinto ze-substrate.
Ama-PCB wephepha
Lolu hlobo lwebhodi lesifunda eliphrintiwe lenziwe nge-fiber paper njengento yokuqinisa, efakwe kwisisombululo se-resin (i-phenolic resin, i-epoxy resin) futhi yomisiwe, bese ihlanganiswa ne-glue-coated electrolytic foil yethusi, futhi icindezelwe ngaphansi kokushisa okuphezulu nokucindezela okukhulu. Ngokusho kwe-American ASTMAmazinga we-NEMA, izinhlobo eziyinhloko yi-FR-1, FR-2, FR-3 (okungenhla kuyi-XPC ye-flame retardant, XXXPC (okungenhla akukona ukubuyiswa kwamalangabi). Okuvame ukusetshenziswa kakhulu nokukhiqiza okukhulu i-FR-1 kanye namabhodi esekethe aphrintiwe we-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. Ku-ASTM/NEMA ejwayelekile, kunamamodeli angu-4 endwangu ye-epoxy fiberglass: G10 (non-flame retardant), FR-4 (i-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, okomlilo, okokuvikela nokuvikeleka, okokuxhumana ngocingo, ama-LED, izingxenye zezimoto, izinhlelo zokusebenza zasolwandle, izingxenye ze-aerospace, izicelo zokuvikela nezempi, kanye nezinye izinhlelo zokusebenza eziningi. 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 STYLECNCUbuchwepheshe bokusika i-laser ukuphatha izinto eziyisisekelo ngaphandle kwe-carbonization kanye nokushintsha umbala. Ngaphezu kwalokho, ukuze uvimbele ukwehluleka ohlelweni lokusika, STYLECNC futhi wenze imiklamo ehlobene emikhiqizweni yayo ukuyivimbela. 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 nge-laser kusindisa okungaphezu kwalokho 30% impahla uma kuqhathaniswa namasu okusika ngomshini. Lokhu akusizi nje kuphela ukunciphisa izindleko zokukhiqiza ama-PCB enhloso ethile, kodwa futhi kusiza ukwakha indawo ezungezile enobungani.
STYLECNCAmasistimu wokusika we-laser 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 ezi-3 ezivame kakhulu zabasiki be-laser be-PCB emhlabeni. Ungenza ukukhetha okufanele ngokuya ngezidingo zakho zebhizinisi lokwenziwa kwe-PCB.
CO2 Ama-Laser Cutter for Custom PCB Prototype
A CO2 umshini wokusika we-laser usetshenziselwa ukusika ama-PCB enziwe ngezinto ezingezona ezensimbi, njengephepha, i-fiberglass, nezinye izinto eziyinhlanganisela. CO2 abasiki be-laser PCB banentengo kusuka $3,000 kube $12,000 ngokusekelwe ezicini ezahlukene.
Umshini Wokusika I-Fiber Laser WePrototype Ye-PCB Yangokwezifiso
I-fiber laser cutter isetshenziselwa ukusika ama-PCB enziwe ngezinto zensimbi, njenge-aluminium, ithusi, insimbi, nensimbi ye-Invar. I-fiber laser PCB cutting system ibiza noma yikuphi ukusuka $1I-4,200 kuya $29,800 ngokuya ngokucushwa kwemithombo ye-laser, amandla e-laser nosayizi betafula.
IHybrid Laser Cutting System ye-Custom PCB Prototype
I-hybrid laser cutting system isetshenziselwa ukusika ama-PCB enziwe ngazo zombili izinsimbi nezingezona ezensimbi. Umshini wokusika we-laser PCB oyi-hybrid uqala kusukela $6,800, kuyilapho ezinye izinhlobo zokugcina eziphezulu zingabiza njengezindleko $12,800.
Ngaphezu kwekhono layo lokusika ama-substrates, ama-laser angaphinda asetshenziselwe ukwenza i-PCB prototyping yangokwezifiso, ukumaka, ukuqopha, ukubhoboza, noma ukunamathisela izendlalelo zento ngayinye.
Ungawukhetha Kanjani Umshini Wokumaka we-Laser we-PCB & Wokuqopha & Wokufaka?
