Umehluko Obalulekile Phakathi kwama-Aluminium nama-FR4 PCB

Amabhodi Esifunda Aphrintiwe akha izimpande zamadivayisi kagesi anamuhla, kanye nama-PCB e-Aluminium kanye nama-PCB e-FR4 abonakala njengezinhlobo ezimbili ezisetshenziswa kakhulu. Womabili anezici ezihlukile futhi asetshenziswa ezinhlelweni ezahlukene. Lesi sihloko sihlose ukukusiza ukuthi ucacise umehluko phakathi kwama-PCB e-Aluminium kanye nama-FR4 , sikusize ekwenzeni izinqumo zakho lapho uqala iphrojekthi entsha ye-elekthronikhi.

Ukwakhiwa kwezinto

Ama-PCB e-Aluminium: Afaka umgogodla wensimbi, ngokuvamile owenziwe nge-aluminium noma ingxubevange ye-aluminium. Lo mgogodla unikeza ukuchithwa kokushisa okuhle kakhulu, okuwenza alungele ukuphathwa kwe-thermal ezinhlelweni zokushisa okuphezulu.
Ama-FR4 PCB: Enziwe ngengilazi i-fiber-reinforced epoxy resin, ehlinzeka ngokufaka ugesi okuhle namandla okusebenza. I-“FR” ku-FR4 imele i-Flame Retardant, ehlangabezana nezimfuneko ze-UL 94V-0.

Ukuqhuba Ukushisa

Ama-PCB e-Aluminium: Ziqhayise nge-thermal conductivity ephezulu, idlulisa kahle futhi ikhiphe ukushisa. Le khwalithi ibalulekile ezinhlelweni ezifana ukukhanyisa LED kanye ne-power electronics.
Ama-FR4 PCBs: Anokungabi namandla kwe-thermal conductivity uma kuqhathaniswa nama-Aluminium PCBs, okuwenza angalungeli kakhulu izinhlelo ezisezingeni lokushisa eliphezulu.

Amandla Mechanical kanye Nokuqina

Ama-PCB e-Aluminium: Bonisa amandla amakhulu emishini nokuqina ngenxa yesisekelo sensimbi. Abajwayele ukungqubuzana, okubenza bafanelekele izinhlelo zokusebenza eziqinile.
FR4 PCBs: Nikeza amandla ahloniphekile emishini kodwa angaba brittle uma kuqhathaniswa nama-Aluminium PCBs.

Izindleko

Aluminium PCBs: Ngokuvamile kubiza kakhulu ngenxa yezindleko eziphezulu zempahla kanye nezinqubo zokwenziwa eziyinkimbinkimbi.
Ama-FR4 PCB: Angabizi kakhulu, atholakala kabanzi, futhi aguquguqukayo, okuwenza abe yinketho edumile yezinhlelo zokusebenza ezahlukahlukene.

Ukucaciswa Kohlelo

Ama-PCB e-Aluminium: Asetshenziswa kakhulu ezinhlelweni zamandla aphezulu njengokukhanya kwe-LED, ugesi wezimoto, namamojula wamandla ngenxa yamandla okuphatha okushisayo aphakeme.
Ama-FR4 PCBs: Aguquguquka futhi afanele uhla olubanzi lwezinto zikagesi, ikakhulukazi lapho ukuhanjiswa kwe-thermal ephezulu kungeyona into ekhathaza kakhulu.

Ukwendlaleka nokuqina

Ama-PCB e-Aluminium: Ngokuvamile ahlanganisa izendlalelo ezintathu, okuhlanganisa i-aluminium substrate, isendlalelo se-copper conductive, nesendlalelo se-dielectric. Ngokuvamile zikhawulelwe ngokuya ngokubala kwesendlalelo nokuqina ngenxa yosayizi we-dielectric noma isendlalelo sensimbi esisekelayo.

Ama-FR4 PCB: Angahluka ukusuka kungqimba olulodwa ukuya ekucushweni kwezendlalelo eziningi, anikeze ukuguquguquka okukhulu ekwakhiweni nasekujimeni. Lokhu kwenza ama-FR4 PCB afanele uhla olubanzi lwezinhlelo zokusebenza ze-elekthronikhi, ikakhulukazi lapho ukujiya kwebhodi kuyadingeka khona.

Ukunwetshwa Okushisayo

Ama-PCB e-Aluminium: Iba ne-coefficient ephansi yokwanda kwe-thermal (CTR) uma kuqhathaniswa ne-FR4, eseduze ne-CTR yethusi. Lesi sakhiwo sinciphisa ubungozi bezinkinga ezihlobene nokwanda okushisayo ku-PCB, njengokuphuka kwemigqa yethusi nezimbobo ezenziwe ngensimbi.
Ama-FR4 PCBs: Iba ne-CTR ephakeme, engaholela ezinkingeni ngokunwetshwa okushisayo, okuthinta ukwethembeka kwebhodi kwezinye izinhlelo zokusebenza

Ukukhetha phakathi kwama-Aluminium PCBs nama-FR4 PCB kuncike ezimfuneko ezithile zohlelo lwakho lokusebenza. Ama-PCB e-Aluminium ahamba phambili ezimeni ezidinga ukulahlwa kokushisa okusebenzayo namandla, njengasezinhlelweni ze-LED ezinamandla amakhulu kanye nogesi wezimoto. Ngakolunye uhlangothi, ama-FR4 PCB ayinketho eguquguqukayo futhi eyongayo yohlu olubanzi lwemishini kagesi, ikakhulukazi lapho ukuphathwa kwe-thermal kungeyona into ekhathaza kakhulu. Ukuqonda lo mehluko kubalulekile ekuthuthukiseni ukusebenza nokuthembeka kwamaphrojekthi akho e-elekthronikhi.
