Chii chinonzi PCB?
PCB inoreva Printed Circuit Board, inova inotakura magetsi ekubatanidza zvinhu zvemagetsi uye chikamu chepakati chezvese zvigadzirwa zvemagetsi. PCB inozivikanwa zvakare sePWB (Printed Wire Board).
Ndeapi marudzi ePCB zvinhu zvinogona kutemwa nema laser cutters?
Mhando dzePCB zvinhu zvinogona kuchekwa nechaizvo laser cutter dzinosanganisira simbi-yakavakirwa yakadhindwa edunhu mabhodhi, mapepa-based akadhindwa edunhu mabhodhi, epoxy girazi faibha yakadhindwa edunhu mabhodhi, composite substrate yakadhindwa edunhu mabhodhi, yakakosha substrate yakadhindwa edunhu mabhodhi uye mamwe substrate. zvinhu.
Pepa PCBs
Rudzi urwu rwebhodhi redunhu rakadhindwa rakagadzirwa nefiber bepa sechinhu chinosimbisa, chakanyikwa mune resin solution (phenolic resin, epoxy resin) uye yakaomeswa, yobva yaputirwa neglue-yakavharidzirwa electrolytic foil yemhangura, uye yakatsikirirwa pasi pekupisa kwakanyanya uye kudzvanywa kwakanyanya. . Zvinoenderana nezviyero zveAmerican ASTM/NEMA, mhando huru dzinoti FR-1, FR-2, FR-3 (iri pamusoro inodzora murazvo weXPC, XXXPC (iri pamusoro haidzoreri murazvo). Inonyanya kushandiswa uye yakakura- kugadzirwa kwechiyero ndeye FR-1 uye XPC yakadhindwa mabhodhi edunhu.
Fiberglass PCBs
Iri rudzi rweakadhindwa redunhu bhodhi rinoshandisa epoxy kana yakagadziridzwa epoxy resin seyakadzika zvinhu zvekunamira, uye girazi fiber jira sechinhu chinosimbisa. Parizvino ndiro hombe rakadhindwa redunhu bhodhi munyika uye ndiyo inonyanya kushandiswa mhando yeakadhindwa redunhu bhodhi. Muchiyero cheASTM/NEMA, pane mamodheru mana eepoxy fiberglass jira: G10 (isina-flame retardant), FR-4 (flame retardant). G11 (chengetedza simba rekupisa, kwete murazvo wemoto), FR-5 (chengetedza simba rekupisa, murazvo wemoto). Muchokwadi, zvigadzirwa zvisiri-murazvo zvinodzikira gore negore, uye FR-4 inoverengera ruzhinji.
Composite PCBs
Rudzi urwu rwekudhindwa redunhu bhodhi rinobva pakushandiswa kwezvinhu zvakasiyana-siyana zvekusimbisa kugadzira hwaro zvinhu uye core material. Iwo emhangura akapfeka laminate substrates anoshandiswa anonyanya CEM akatevedzana, pakati pawo CEM-1 uye CEM-3 ndiwo anomiririra zvakanyanya. CEM-1 base jira igirazi fiber jira, core material ipepa, resin is epoxy, flame retardant. CEM-3 base jira igirazi faibha jira, musimboti zvinhu igirazi faibha bepa, resin is epoxy, murazvo retardant. Hunhu hwakakosha hweiyo composite base yakadhindwa redunhu bhodhi yakaenzana neFR-4, asi mutengo wakaderera, uye machining kuita kuri nani pane FR-4.
Metal PCBs
Metal substrates (aluminium base, chigadziko chemhangura, iron base kana Invar simbi) inogona kugadzirwa kuita imwechete, kaviri, yakawanda-layer simbi yakadhindwa edunhu mabhodhi kana simbi yepakati yakadhindwa mapuranga edunhu zvinoenderana nemaitiro avo uye mashandisiro.
PCB inoshandiswa nei?
PCB (yakadhindwa yedunhu bhodhi) inoshandiswa mumagetsi evatengi, midziyo yeindasitiri, midziyo yekurapa, midziyo yemoto, chengetedzo & chengetedzo midziyo, nharembozha, maLED, zvinhu zvemotokari, maritime application, aerospace components, defense & mauto application, pamwe nezvimwe zvakawanda. applications. Mukushandisa zvine kuchengetedzwa kwepamusoro zvinodiwa, maPCB anofanirwa kusangana nemhando yepamusoro, saka isu tinofanirwa kutora zvese zvese zvePCB kugadzira maitiro.
Laser cutter inoshanda sei paPCBs?
Chekutanga, kucheka PCB nelaser kwakasiyana nekucheka nemichina yakadai sekugaya kana kutsika. Kucheka kweLaser hakuzosiyi guruva paPCB, saka hazvizokanganisa kushandiswa kwekupedzisira, uye kushushikana kwemagetsi uye kushushikana kwekupisa kunounzwa nelaser kune zvikamu hazvina basa, uye maitiro ekucheka akapfava.
Uye zvakare, laser tekinoroji inogona kusangana nehutsanana zvinodiwa. Vanhu vanogona kugadzira PCB nehutsanana hwepamusoro uye hwemhando yepamusoro kuburikidza neSTYLECNC's laser yekucheka tekinoroji yekurapa hwaro zvinhu pasina carbonization uye discoloration. Pamusoro pezvo, kuitira kudzivirira kutadza mukucheka, STYLECNC yakaitawo madhizaini ane hukama muzvigadzirwa zvayo kudzivirira. Naizvozvo, vashandisi vanogona kuwana yakanyanya kukwira goho mwero mukugadzira.
Muchokwadi, nekungogadzirisa maparamendi, munhu anogona kushandisa imwechete laser yekucheka chishandiso kugadzira akasiyana zvinhu, senge zvakajairwa zvikumbiro (senge FR4 kana ceramics), insulated simbi substrates (IMS) uye system-mu-mapakeji (SIP). Uku kuchinjika kunoita kuti maPCB ashandiswe munzvimbo dzakasiyana siyana, senge kutonhora kana kudziyisa masisitimu einjini, chassis sensors.
Mukugadzirwa kwePCB, hapana zvirambidzo pane ratidziro, radius, label kana zvimwe zvinhu. Kuburikidza nekucheka kwakazara-denderedzwa, PCB inogona kuiswa zvakananga patafura, iyo inovandudza zvakanyanya kushanda kwekushandisa nzvimbo. Kucheka maPCB nelaser kunochengetedza zvinopfuura 30% zvinhu zvichienzaniswa nemakanika ekucheka matekiniki. Izvi hazvingobatsiri kudzikisira mutengo wekugadzira chaiwo-chinangwa maPCB, asiwo zvinobatsira kuvaka nharaunda ine hushamwari yezvakatipoteredza.
STYLECNC's laser yekucheka masisitimu anogona kubatanidzwa nyore nyore nearipo Manufacturing Execution Systems (MES). Iyo yepamusoro laser system inovimbisa kugadzikana kwemaitiro ekushanda, nepo otomatiki chimiro cheiyo system zvakare inorerutsa maitiro ekushanda. Nekuda kwesimba repamusoro reiyo yakasanganiswa laser sosi, yanhasi laser michina inofananidzwa zvizere nemakanika masisitimu maererano nekumhanya kwekucheka.
Uyezve, mutengo wekushandisa welaser system wakadzikira sezvo pasina kupfeka zvikamu zvakaita semisoro yekugaya. Mutengo wekutsiviwa kwezvikamu uye nguva inokonzeresa yekudzikira inogona kudziviswa.
Ndeapi marudzi emalaser cutters anoshandiswa kugadzira PCB?
Kune matatu akajairika marudzi ePCB laser cutters munyika. Iwe unogona kuita sarudzo yakanaka zvinoenderana nePCB yekugadzira bhizinesi zvido.
CO2 Laser Cutters for for Custom PCB Prototype
A CO2 laser yekucheka muchina unoshandiswa kucheka maPCB akagadzirwa nezvinhu zvisiri zvesimbi, senge bepa, fiberglass, uye zvimwe zvinoumbwa zvinhu. CO2 laser PCB cutters vari mutengo kubva $3,000 kusvika $12,000 zvichienderana akasiyana maficha.
Fiber Laser Yekucheka Muchina weCustom PCB Prototype
Fiber laser cutter inoshandiswa kucheka maPCB akagadzirwa nesimbi zvinhu, zvakaita sealuminium, mhangura, simbi, uye Invar simbi.
