Seboka sa Metal Core PCB | Litharollo tsa Boenjiniere bakeng sa Likopo tse Matla a Phahameng

Selelekela

Di-elektronike tse matla a hodimo di hloka taolo e sebetsang hantle ya mocheso ho boloka tshebetso le botshepehi. Le hoja di-substrate tsa Metal Core PCB (MCPCB) di fana ka thepa e ntle ya ho qhala mocheso , ditsamaiso tsa kopano le tsa ho paka di qetella di etsa qeto ya hore na melemo ena ya mocheso e fetolela tshebetsong ya lefatshe la nnete.

Litloaelo tse fosahetseng tsa kopano li ka senya litsela tsa mocheso, tsa etsa lintlha tsa khatello ea mochine, 'me tsa lebisa ho hloleheng ha tšimo pele ho nako. Seboka sa Metal Core PCB se hloka tsebo e khethehileng ho feta boto e tloaelehileng ea FR-4.

Karolo ea tšepe ea tšepe e hlahisa mathata a ikhethang ho solder, fixturing, le taolo ea khatello ea maikutlo eo mekhoa e tloaelehileng ea kopano ea PCB e ke keng ea khona ho e rarolla ka ho lekana. Sengoliloeng sena se hlahloba litharollo tse sebetsang tse shebaneng le ho ts'epahala ha solder, ho ntlafatsa tsela ea mocheso, le taolo ea khatello ea maikutlo.

Mathata a Kopano ea Metal Core PCB

1. Thermal Management ka Metal Core PCB Kopano

Seboka se Atlehang sa Metal Core PCB se hloka ho boloka tsela e tsoelang pele ea mocheso ho tloha ho likarolo ka manonyeletso a solder ho ea substrate ea tšepe. Likarolo tsa matla a phahameng li hlahisa mocheso o moholo, kahoo lisebelisoa tse nepahetseng tsa mocheso oa mocheso (TIM) le botšepehi ba solder li bohlokoa.

Lera la motheo la koporo kapa la aluminium le atoloha ka tsela e fapaneng le likarolo tsa dielectric le tsa koporo, li baka khatello ea maikutlo nakong ea ho palama baesekele. Ntho leha e le efe ea khanyetso e phahameng ea mocheso e ka phahamisa mocheso oa motsoako oa likarolo le ho fokotsa ho tšepahala.

2. Ho tšepahala ho Soldering ho Tlhahiso ea MCPCB

Theknoloji ea ho kenya holim'a metsi (SMT) le ho kenya ka har'a lesoba (THP) ka bobeli li hlahisa liphephetso tse ikhethang. Lisebelisoa tsa tšepe li hloka liprofaele tse fetotsoeng tsa ho phalla hape tse nang le libaka tse atolositsoeng tsa pele ho mocheso le mocheso o laoloang ka hloko ho qoba liphoso tsa manonyeletso a solder kapa ho arohana ha dielectric. Ho kopanya maqhubu le ho kopanya ka ho khetha ho tlameha ho ikarabella bakeng sa phello ea ho teba ha mocheso oa substrate ho netefatsa hore ho kolobisoa ha solder hantle likarolong tse kenang ka har'a lesoba.

3. Khatello ea Mechane Kopanong ea MCPCB

Phapang ho coefficient of thermal expansion (CTE) pakeng tsa substrate ea tšepe le likarolo tsa koporo/dielectric li baka khatello ea tlhaho ea mechini nakong ea kopano le ts'ebetso. Li-MCPCB tse nang le sebopeho se seholo kapa meralo e thata e feto-fetohang li sekametse haholo ho sotha nakong ea phallo e ncha, e leng se ka lebisang ho se lumellaneng ha likarolo, ho betla mabitla, kapa ho hokahanya ha solder. Mekhoa e nepahetseng ea ho lokisa le ho sebetsana le eona ea bohlokoa ho aba matla ka ho lekana le ho thibela ho sotha ha substrate.

Mekhoa e Molemo ka ho Fetisisa ea Kopano ea Metal Core PCB

1. Thermal Pathway Optimization

Ho boloka mocheso o tswela pele ho tloha dikarolong ho ya ho substrate ya tshepe ho bohlokwa. Kenya thepa ya sebopeho sa mocheso (TIMs) ho 50–100 µm ho leka-lekanya ho hanyetsa mocheso le ho dumellana le bokahodimo. Sebedisa dikarolo tsa koporo tsa 2–3 oz. hodima meedi ya motlakase o phahameng ho ntlafatsa ho ata ha mocheso.

Lintlha tsa bohlokoa:

• Tsela e khuts'oane ea mocheso - phallo e tobileng ea mocheso ho setsi sa tšepe.
• Ho beha tšepe e tiileng - beha likarolo tsa matla a phahameng holim'a libaka tsa tšepe tse tsoelang pele.
• Botenya ba TIM bo laoloang - 50–100 µm bakeng sa phetiso e nepahetseng ea mocheso.
• Mesaletsa ea koporo e boima - ntlafatsa ho hasana ha mocheso le bokhoni ba hona joale.

2. Soldering Process Control

Ntlafatso ea profil ea Reflow e bohlokoa haholo. Butle-butle futhumatsa MCPCB (li-s tse 90-120) ho fokotsa ho tšoha ha mocheso. Boloka mocheso o phahameng ka har'a meeli ea dielectric (hangata 260-280 °C) 'me nako e be kaholimo ho liquidus 60-90 s bakeng sa solder e se nang loto.

Bakeng sa wave soldering, preheat likopano ho etsa bonnete ba hore mocheso o fetisa. Solder e khethiloeng e lumella ho futhumatsa hantle ha liboto tsa theknoloji e tsoakiloeng ha ho ntse ho fokotsa ho pepeseha ha substrate ho mocheso o phahameng. Preheat hangata 100-120 °C.

3. Ho Fokotsa Khatello ea Mechini

Ho lokisoa hantle ho fokotsa kotsi ea mathata. Sebelisa likhoele tsa tšehetso kapa marang-rang a marang-rang, ho qoba ho koala feela. Bakeng sa lisebelisoa tsa vacuum, boloka khatello ea 0.3-0.5 bar ho sireletsa dielectric.

Taba ea leano la ho beha likarolo: aba likarolo tse boima ka ho lekana ho thibela ho kobeha ha libaka. Ho li-MCPCB tse thata, tlohela libaka tse feto-fetohang li sa hatelloe nakong ea ho phalla hape ka tumello ea ≥3 limilimithara nakong ea liphetoho tse thata.

4. Teko le Netefatso

Tlhahlobo ea motlakase le pono ke ea bohlokoa. Liteko tse tsamaeang ka sefofane li netefatsa ho tsoela pele ha motlakase, 'me AOI e lemoha mefokolo ea solder le ho se tsamaisane hantle ha likaroloana. Sebelisa liparamente tsa tlhahlobo tse ikhethileng tsa MCPCB.

Ho netefatsa ts'ebetso ea mocheso ho kenyelletsa ho palama libaesekele tse futhumetseng (-40 ° C ho ea + 125 ° C, 500-1000 cycles) ho netefatsa ho tšepahala. Litšoantšo tsa mocheso li khetholla libaka tse chesang haholo 'me li netefatsa hore phapang ea mocheso e lula ka har'a 10 °C.
