Taolo ea boholo le phetoho ea boholo ba 6-layer PCB: tikoloho ea mocheso o phahameng le khatello ea mochine

Mokhoa oa ho rarolla bothata ba taolo ea boholo le phetoho ea sebopeho sa 6-layer PCB: ho ithuta ka hloko ka tikoloho e phahameng ea mocheso le khatello ea maikutlo.

Selelekela

Moralo le tlhahiso ea boto e hatisitsoeng (PCB) e tobane le liphephetso tse ngata, haholoholo mabapi le ho boloka taolo ea maemo le ho fokotsa ho fapana ha maemo. Sena ke 'nete haholo bakeng sa li-PCB tsa 6-layer tse tlas'a maemo a mocheso o phahameng le khatello ea mochine. Ka poso ena ea blog, re tla hlahloba maano le mekhoa e sebetsang ea ho hlola litaba tsena le ho netefatsa botsitso le ts'epahalo ea li-PCB tse joalo.

Utloisisa bothata

E le ho rarolla bothata leha e le bofe ka katleho, ke habohlokoa ho qala ho utloisisa sesosa sa eona. Tabeng ea taolo ea boholo le liphetoho tsa dimensional tsa 6-layer PCBs, lintlha tse peli tse ka sehloohong li phetha karolo ea bohlokoa: tikoloho ea mocheso o phahameng le khatello ea mochine.

Boemo bo phahameng ba mocheso

Libaka tse phahameng tsa mocheso, nakong ea ts'ebetso le tlhahiso, li ka baka katoloso ea mocheso le ho fokotseha ka har'a thepa ea PCB. Sena se ka baka liphetoho ka boholo le boholo ba boto, ho senya ts'ebetso ea eona ka kakaretso. Ho feta moo, mocheso o mongata haholo o ka etsa hore lenonyeletso la solder le fokotsehe kapa le robehe, ho baka liphetoho tse ling tsa sebopeho.

Khatello ea mechine

Khatello ea kelello ea mochini (joalo ka ho kobeha, ho kheloha kapa ho sisinyeha) le eona e ka ama taolo ea sebopeho le botsitso ba sebopeho sa 6-layer PCBs. Ha ba tlas'a matla a ka ntle, lisebelisoa tsa PCB le likarolo li ka 'na tsa senyeha' meleng, tse ka fetolang boholo ba tsona. Sena se bohlokoa haholo lits'ebetsong moo PCB e atisang ho ba tlas'a khatello ea maikutlo kapa khatello ea maikutlo.

Litharollo le Theknoloji

1. Khetho ea lintho tse bonahalang

Ho khetha thepa e nepahetseng ho bohlokoa ho fokotsa taolo ea litekanyo le ho fapana ha li-dimensional bakeng sa li-PCB tsa 6-layer. Khetha lisebelisoa tse nang le coefficient e tlase ea keketseho ea mocheso (CTE) kaha li ke ke tsa hlaseloa habonolo ke ho fetoha ha mocheso. Li-laminate tsa mocheso o phahameng, tse kang polyimide, li ka boela tsa sebelisoa ho matlafatsa botsitso ba boemo bo phahameng ba mocheso.

2. Tsamaiso ea mocheso

Ho kenya ts'ebetsong mekhoa e sebetsang ea tsamaiso ea mocheso ho bohlokoa ho sebetsana le maemo a phahameng a mocheso. Ho etsa bonnete ba hore e loketseng mocheso dissipation ka tshebediso ya lisinki mocheso, vias mogote, 'me pads mogote thusa ho boloka kabo e tsitsitseng mocheso pholletsa PCB eohle. Sena se fokotsa monyetla oa ho hola le ho honyela ha mocheso, ho fokotsa litaba tsa taolo ea boholo.

3. Ho imolla khatello ea kelello ka mechine

Ho nka mehato ea ho fokotsa le ho qhalakanya khatello ea kelello ea mochini ho ka ntlafatsa haholo botsitso ba li-PCB tsa 6-layer. Ho matlafatsa boto ka meaho ea ts'ehetso kapa ho kenya ts'ebetsong li-stiffeners ho ka thusa ho fokotsa ho kobeha le ho kheloha, ho thibela mathata a taolo ea boholo. Ho feta moo, ts'ebeliso ea thekenoloji ea phokotso ea vibrate e ka fokotsa tšusumetso ea ho thothomela kantle ho PCB.

4. Ho tšepahala moralo

Ho rala li-PCB ka ho ts'epaha kelellong ho phetha karolo ea bohlokoa ho fokotsa ho fapana ha li-dimensional. Sena se kenyelletsa ho nahana ka lintlha tse kang trace routing, ho beha likarolo, le layer stacking. Mesaletsa e reriloeng ka hloko le lifofane tse sebetsang hantle tsa fatše li fokotsa monyetla oa ho senyeha ha matšoao ka lebaka la liphetoho tsa boholo. Ho beha likarolo tse nepahetseng ho ka thibela libaka tse chesang hore li se ke tsa hlahisa mocheso o feteletseng, ho thibela mathata a ho laola boholo.

5. Ts'ebetso e matla ea tlhahiso

Tšebeliso ea mekhoa e tsoetseng pele ea tlhahiso e behang leihlo ka hloko le ho laola maemo a mocheso e ka thusa haholo ho boloka taolo ea boholo le ho fokotsa liphetoho tsa boholo. Mekhoa e nepahetseng ea welding le kabo e nepahetseng ea mocheso nakong ea kopano e thusa ho netefatsa manonyeletso a matla le a tšepahalang a solder. Ho feta moo, ho kenya ts'ebetsong mekhoa e nepahetseng ea ho sebetsana le ho boloka nakong ea ho etsa le ho romela thepa ho ka fokotsa liphetoho tse bakoang ke khatello ea kelello.

Ha re phethela

Ho fihlella taolo e nepahetseng ea litekanyo le botsitso ba likarolo ho PCB ea 6-layer, haholo-holo libakeng tse phahameng tsa mocheso le maemo a khatello ea mochini, ho hlahisa liphephetso tse ikhethang. Liphephetso tsena li ka hlōloa ka khetho e hlokolosi ea lisebelisoa, ts'ebetsong ea tsamaiso e sebetsang ea mocheso le mekhoa ea ho imolla khatello ea kelello, moralo oa ho tšepahala, le tšebeliso ea mekhoa e matla ea tlhahiso. Hopola hore mokhoa o entsoeng hantle oa ho sebetsana le lintlha tsena o ka netefatsa botsitso le botšepehi ba PCB ea 6-layer, ka tsela eo ho netefatsa hore e sebetsa ka katleho lits'ebetsong tse fapaneng tsa bohlokoa.
