Selelekela

Tlhahiso ea aluminium PCB ea Prototype e sebetsa e le sebaka sa bohlokoa sa ho hlahloba nts'etsopele ea lisebelisoa tsa elektroniki, haholo bakeng sa lits'ebetso tse hlokang taolo e phahameng ea mocheso. Ha matla a matla a eketseha 'me mocheso oa motsoako o phahama, liboto tsa potoloho tse hatisitsoeng tse thehiloeng ka aluminium li ba bohlokoa bakeng sa ho qhala mocheso hantle. Karolo ea prototyping e lumella baenjiniere ho netefatsa ts'ebetso ea mocheso, ho netefatsa kopanyo ea mochini, le ho netefatsa ts'epo ea kopano pele ba itlama ho hlahisa molumo.

Tataiso ena e hlahloba ts'ebetso e felletseng ho tloha ho aluminium PCB ea prototyping e potlakileng ho isa ho maqheka a manyane, ho thusa lihlopha tsa meralo ho ntlafatsa ts'ebetso ea tekheniki le moruo oa tlhahiso.

Karolo ea Prototype Aluminium PCB ho Ntlafatso ea Sehlahisoa

Likopo tse Hlokang Tsamaiso ea Thermal

Lisebelisoa tsa elektroniki tse matla haholo ho kenyeletsoa le litsamaiso tsa mabone a LED, li-module tsa motlakase tsa likoloi, le balaoli ba li-engine tsa indasteri ba itšetlehile ka li-PCB tsa aluminium substrate ho laola meroalo ea mocheso eo thepa e tloaelehileng ea FR-4 e ke keng ea e sebetsana. Karolo ea tšepe e fana ka litsela tse tobileng tsa ho tsamaisa mocheso ho tloha likarolong ho ea li-heat sinks, e fokotsa mocheso oa li-junction le ho atolosa nako ea ts'ebetso.

Maikemisetso a Bohlokoa a Tiisetso

Prototype aluminium PCB netefatso e araba lipotso tsa bohlokoa tsa moralo: hore na botenya ba lera la dielectric le fana ka karohano e lekaneng ea motlakase ha o ntse o boloka conductivity ea mocheso, mokhoa oa ho futhumatsa mocheso o tsamaisang mocheso ka har'a boto, le hore na ts'ebetso ea kopano e fihlela manonyeletso a ka tšeptjoang a solder holim'a likaroloana tsa tšepe. Ho sibolla mefokolo ea moralo nakong ea tlhahiso ea sampole ea PCB ea aluminium e tlase haholo ho feta ho hloleha nakong ea tlhahiso e ngata, ho sireletsa lichelete tsa nts'etsopele le ho potlakisa nako ea ho ea 'marakeng.

Aluminium PCB Prototype Manufacturing process

Tlhahiso ea Moralo le Tlhahlobo ea DFM

Ts'ebetso ea PCB ea aluminium ea mohlala e qala ha lifaele tsa moralo li hlahlojoa ke Design for Manufacturability . Baenjiniere ba hlahloba mekhoa ea lera la koporo, ka libaka, le boholo ba likarolo tse fokolang khahlanong le bokhoni ba tlhahiso. DFM bakeng sa li-prototype tsa PCB tsa aluminium e kenyelletsa tlhahlobo ea mocheso ka sebaka, liteko tsa ho lumellana ha lera la dielectric, le khetho ea ho qeta bokaholimo ho latela litlhoko tsa kopano.

Lisebelisoa le Khetho ea Stack-up

Khetho ea aluminium substrate e ama ka kotloloho ts'ebetso ea mocheso le litšenyehelo. Botenya ba motheo ba aluminium hangata bo fapana ho tloha ho 1.0mm ho isa ho 3.0mm, ha likarolo tsa dielectric li fapana pakeng tsa 50μm le 200μm ho latela litlhoko tsa ho itšehla thajana. Li-dielectrics tse phahameng tsa mocheso oa mocheso li thusa ho fetisa mocheso hantle empa li eketsa litšenyehelo tsa thepa. Netefatso ea prototype le liteko li netefatsa hore na sephutheloana se khethiloeng se fihlella lipehelo tsa mocheso tlas'a maemo a sebele a ts'ebetso.

Mehato ea Boqapi

Ho cheka ha CNC ho etsa masoba a likarolo le li-vias tse futhumetseng tse nang le boemo bo nepahetseng ba bohlokoa bakeng sa litsela tsa ho qhala mocheso. Ho fetisoa ha setšoantšo ho sebetsa mokhoa oa potoloho ka photolithography, e lateloa ke etching ho hlalosa litsela tsa koporo. Ts'ebeliso ea mask ea solder e sireletsa koporo ha e ntse e pepesa liphaephe bakeng sa sehokelo sa karolo. Likhetho tsa ho qeta bokaholimo ho kenyelletsa HASL le ENIG li tsebahatsa hore na li ka rekisoa joang le bophelo ba sethala, ka mohato o mong le o mong o hlokang taolo ea ts'ebetso e ikamahanyang le likaroloana tsa tšepe.

Transitioning Prototype Aluminium PCB to Small-Batch Production

Ntlafatso ea Moqapi le Ts'ebetso e tsitsitseng

Phetoho ho tloha ho di-prototype tse netefaditsweng ho ya ho tlhahiso ya PCB e nyane e emela mohato wa bohlokwa moo ditshebetso tsa tlhahiso di holang le ho tsitsisa. Baenjiniere ba ntlafatsa dintlha tsa moralo ho latela diphihlello tsa di-prototype: ho fetola mocheso ka bongata, ho fetola boima ba koporo, kapa ho fetola di-geometri tsa karolo ya pad ho ntlafatsa chai ya kopano. Diparamitha tsa tshebetso tse thehilweng nakong ya tlhahiso ya sampole ya aluminium PCB di notlella botsitso ho pholletsa le dipehelo tse ngata tsa tlhahiso.

Netefatso ea Tlhahiso ea Batch e Nyane

Ho sebetsa ha kopano ea PCB ka bongata bo tlase hangata ho tloha ho li-unit tse 50 ho isa ho tse 500, ho fana ka lintlha tse nang le moelelo oa lipalo-palo mabapi le bokhoni ba ts'ebetso ha ka nako e ts'oanang ho fokotsa ho pepesehela lichelete. Mokhahlelo ona o netefatsa hore lisebelisoa tsa tlhahiso, lisebelisoa le mekhoa li fana ka liphetho tse ka phetoang. Teko e tiisa hore na bafepedi ba boloka botsitso ba thepa, hore na lits'ebetso tsa kopano li fihlela boleng ba kopanelo ea solder bo reriloeng ka ho etsa profiling ea phallo e ncha, le hore na mekhoa ea tlhahlobo e tšoara liphoso ka mokhoa o tšepahalang.

Ho Itokisetsoa ha Ketane ea Phepelo

Phetoho ea tlhahiso ho ea ho bongata e lekola botsitso ba phepelo. Linako tsa ho etella pele tsa aluminium substrate, ho fumaneha ha thepa ea dielectric, le lisebelisoa tsa lik'hemik'hale tse ka holimo li hloka tlhahlobo ho thibela tšitiso ea tlhahiso. Baetsi ba theha manane a barekisi ba tšoanelehang le likhetho tsa ho fumana backup nakong ea mekhahlelo e menyenyane, ho sireletsa khahlano le khaello ea thepa.

Ntlafatso ea Litšenyehelo le Nako ea Pele bakeng sa Prototype Aluminium PCB

Lintlha tse ka sehloohong tsa litšenyehelo

Litšenyehelo tsa Prototype aluminium PCB li bonts'a litšenyehelo tsa ho seta tse ajoang ka bongata bo fokolang, e leng se bakang litheko tse phahameng tsa yuniti ho feta tlhahiso ea molumo. Bakhanni ba bohlokoa ba litšenyehelo ba kenyelletsa:

• Boitsebiso bo lintho tse bonahalang - Li-alloys tse tloaelehileng tsa aluminium li bitsa chelete e ka tlaase ho libopeho tse khethehileng; high-thermal-conductivity dielectrics laela ditefello
• Khetho ea ho qetela ea sefahleho - ENIG e fana ka bophelo bo holimo, empa e eketsa litšenyehelo ha e bapisoa le HASL
• Feature tolerances - Bophahamo bo fokolang ba ho latella le sebaka sa sebaka se hloka lisebelisoa tse nepahetseng le taolo e hlokolosi ea ts'ebetso
• Laela bongata - Li-batch tse kholo tsa mohlala li fokotsa litšenyehelo tsa yuniti ka 'ngoe ha li ntse li fana ka likarolo tse ling bakeng sa tlhahlobo

Tsamaiso ea Nako ea Ketapele

Litšebeletso tse potlakileng tsa aluminium PCB tsa prototyping li fana ka matsatsi a 3-5 leha litheko tsa pele li sebetsa. Linako tse tloaelehileng tsa ho etella pele tsa matsatsi a 7-10 hangata li na le chelete e ngata bakeng sa mananeo a ntlafatso a lumellang nako ea ho leta e itekanetseng. Moralo oa liphanele nakong ea mohato oa prototype o itokisetsa sekhahla sa tlhahiso e sebetsang ka ho holisa tšebeliso ea thepa ho pholletsa le boholo bo tloaelehileng ba phanele.

Tlhahlobo ea Boleng le Bopaki

Teko ea Ts'ebetso ea Motlakase

Mekhoa e felletseng ea liteko e netefatsa hore li-PCB tsa aluminium tsa mohlala li fihlela litlhaloso tsa ts'ebetso. Teko ea motlakase e netefatsa ho tsoela pele ha potoloho ho pholletsa le matlooa 'ohle 'me e tiisa khanyetso ea ho futhumatsa lipakeng tsa lipotoloho le motheo oa aluminium e fetang meeli ea polokeho, hangata e hlokang boleng bo kaholimo ho 100MΩ. Litekanyo tsena li lemoha liphoso tsa tlhahiso ho kenyeletsoa le ho se lekane ho fata, likarolo tse senyehileng tsa dielectric, kapa ho se lekane ka ho plating.

Netefatso ea Tsamaiso ea Mocheso

Tekolo ea ts'ebetso ea mocheso e emela netefatso ea bohlokoahali bakeng sa li-PCB tsa tšepe tsa mantlha. Baenjiniere ba kenya lisebelisoa tse nang le matla a ho felloa ke matla le ho lekanya mocheso libakeng tse itseng ba sebelisa li-thermocouples kapa lik'hamera tsa litšoantšo tse futhumatsang. Ho bapisa litekanyetso tse lekantsoeng khahlano le likhakanyo tsa papiso ea mocheso ho netefatsa likhakanyo tsa moralo:

• Bokhoni ba ho jala mocheso - Ho lumellana ha mocheso ho pholletsa le boto ho bontša kabo e sebetsang ea mocheso
• Ho lumellana ha mocheso oa Junction - Lithempereichara tsa likarolo li lula li le ka har'a meeli ea database tlas'a mojaro o moholo
• Litekanyetso tsa ho hanyetsa mocheso - Khanyetso e lekantsoeng ho tloha mateanong ho ea ho ambient e bapisa lipalo tsa moralo

Teko ea Khatello ea Mechini

Teko ea khatello ea mochini e hlahloba botsitso ba sekhahla ka ho palama baesekele ho tloha -40 ° C ho ea +125 ° C 'me e lekola botšepehi ba manonyeletso a solder ka mor'a maeto a mocheso. Li-PCB tsa aluminium li atoloha ka litefiso tse fapaneng ho feta liboto tse tloaelehileng ka lebaka la motheo oa tšepe, tse ka bakang khatello ea maikutlo likhokahanong tsa likarolo tse tlamehang ho netefatsoa.
