I-METAL CORE PCB
I-Highleap Electronics inikezela ngama-Metal Core PCBs (MCPCBs) wokuphatha okushisayo okusebenzayo ezinhlelweni zamandla aphezulu njengokukhanya kwe-LED, izimoto, nokuningi.
Iyini i-Metal Core PCB
I-Metal Core PCB (MCPCB) isebenzisa ingqikithi yensimbi, efana ne-aluminium noma ithusi, ukuze ithuthukise ukunqanyulwa kokushisa. Ngokungafani namabhodi endabuko e-FR4, ama-MCPCB aphatha ukuminyana kwamandla aphezulu ngenxa yokuguquguquka okuphezulu kwensimbi. Ama-PCB angu-Copper Core anikeza ukuphathwa kokushisa okuphakeme, kuyilapho ama-Aluminium Core PCB ebiza futhi evame ukusetshenziswa ezinhlelweni ezifana nezibani namandla kagesi. Umnyombo uvalwe ngezingqimba ze-ceramic dielectric ukuvimbela izikhindi zikagesi ngenkathi uqinisekisa ukudluliswa kokushisa okuphumelelayo.
Ukuze uthole okwengeziwe ngezinto ze-MCPCB, vakashela Izinto ze-Metal Core PCB . Ukuze ufunde kabanzi mayelana nomklamo we-MCPCB, hlola i-Metal Core Circuit Board.
Isakhiwo se-MCPCB
Ama-Metal Core PCB ahlanganisa izingqimba ezintathu ezibalulekile: umgogodla wensimbi, ungqimba lwe-dielectric, nongqimba lwethusi. Lesi sakhiwo esiyingqayizivele sithuthukisa ukuchithwa kokushisa, sithuthukise ukusebenza okuphelele nokuthembeka kwamasistimu kagesi.
I-metal core, ngokuvamile i-aluminium noma ithusi, iyaziqhayisa nge-thermal conductivity ephezulu namandla okusebenza. Isebenza njengomshini wokushisa, iqhuba kahle futhi isakaze ukushisa kude nezingxenye, igcine izinga lokushisa elilungile lokusebenza futhi ivimbele ukulimala kokushisa.
Isendlalelo se-dielectric, esiboshelwe kumgogodla wensimbi, sinikeza ukufakwa kukagesi kanye nezakhiwo zokulawula ukushisa. Yakhelwe kusuka ezintweni ezinokuguquguquka kwe-thermal okuthuthukisiwe, isiza ukudluliswa kokushisa okusebenzayo kusuka ezingxenyeni kuya kunkambo yensimbi. Isendlalelo se-dielectric siqinisekisa ngisho nokusabalalisa ukushisa, ukunciphisa izindawo ezishisayo nokucindezeleka okushisayo.
Izinzuzo ze-MCPCB
Izici ze-Metal Core PCBs (MCPCB) ezizenza zilungele izinhlelo zokusebenza zamandla aphezulu nezinga lokushisa eliphezulu:
Ama-Metal Core PCB anikeza ukupholisa okuphakeme, ukwethembeka okuthuthukisiwe kanye nomklamo oshisayo owenziwe lula - okuwenza abe yinketho efanelekile yokukhanyisa kwe-LED kwamandla aphezulu, ugesi wezimoto, amamojula okuguqula amandla, njll.

Ukukhipha Ukushisa Okungenazinkathazo, I-Highleap Ikukhavezile! Ama-PCB ethu ayisisekelo ensimbi, ukukhetha okuphelele kokuphathwa okushisayo.
Metal Core PCB Design Guidelines
Ukuphathwa Okushisayo
Ingqikithi yensimbi kuma-MCPCB ihlinzeka ngendlela eqhuba kakhulu yokukhipha ukushisa. Ukuqinisekisa ukudluliswa kokushisa okuphumelelayo, kubalulekile ukuklama ibhodi ngama-vias ashisayo afanele, amaphedi ashisayo, nama-heatsink. Izinga le-thermal kufanele libe seduze nezingxenye ezikhiqiza ukushisa futhi kufanele libe nosayizi owanele ukunikeza ukumelana nokushisa okuphansi.
Ukukhetha Izinto
Khetha ngokucophelela okubalulekile kwensimbi ukuze uthuthukise ukusebenza kwe-MCPCB. I-Aluminium ijwayele ukusetshenziselwa ukuguquguquka kwayo okushisayo okuphezulu, ukusebenza kahle kwezindleko, kanye nezakhiwo ezingasindi. Nokho, ithusi, ithusi, noma insimbi engagqwali ingacatshangelwa ngokusekelwe ezidingweni ezithile zohlelo lokusebenza. Ukwengeza, impahla ye-dielectric kanye nokuqina kwethusi kunomthelela ekusebenzeni kwebhodi jikelele.
Landelela Ububanzi kanye Nezikhala
Dizayina ububanzi bokulandelela obufanele nesikhala ukuze ubambe umthamo wamanje wokuthwala nokugcina ubuqotho besignali. Qinisekisa ukuthi ububanzi bokulandelela banele ukuthwala isimanje esidingekayo ngaphandle kokukhiqiza ukushisa okukhulu. Isikhala esanele phakathi kokulandela umkhondo kunciphisa ukuphazamiseka kwesignali kanye ne-crosstalk. Setha ububanzi obuncane bokulandelela kanye nesikhala ngokusekelwe kuzinqubo zokukhiqiza kanye nezidingo zohlelo lokusebenza.
Ukubekwa Kwengxenye
Ukubekwa kwezingxenye kuma-MCPCB kubalulekile kukho kokubili ukuphatha okushisayo nobuqotho besignali. Izingxenye zamandla aphezulu kufanele zibekwe eduze kwengqikithi yensimbi ukuze kwandiswe ukunqanyulwa kokushisa, kuyilapho izingxenye ezizwelayo njengamasekhethi e-RF kufanele zibekwe kude nomthombo wokushisa. Ukuminyana kwengxenye kufanele kuthuthukiswe ukuze kuqinisekiswe ukusetshenziswa kahle kwendawo yebhodi futhi kugwenywe ukuphazamiseka kwesignali.
I-Solder Mask
Imaski ye-solder kuma-MCPCB kufanele yakhelwe ukwenza lula ukudluliswa kwe-thermal ngenkathi ihlinzeka nge-insulation phakathi kwamathrekhi. Khetha imaski ye-solder ene-matte finish, njengoba inikeza ukuqhutshwa kwe-thermal okuthuthukisiwe. Qinisekisa ukucaciswa okufanele kanye nokumbozwa ukuvimbela ukuvala amabhuloho e-solder namasekethe amafushane. Imaski eklanywe kahle ye-solder ithuthukisa ukusebenza nokuthembeka.
Ukucatshangelwa Kokugcina
Ngokungeziwe kule mihlahlandlela engenhla, naka izinto ezifana nokucatshangelwa kwe-EMC, izidingo zemvelo, namandla okwenza. Ukuqinisekisa ukuthotshelwa kwamazinga emboni afanelekile. Hlanganyela eduze nomkhiqizi wakho we-PCB ukuze uthuthukise idizayini nezinqubo zokukhiqiza zama-MCPCB, uqinisekise ukusebenza okuphakeme, ukwethembeka, nokwaneliseka kwamakhasimende.
