Bala ts'ebetso ea mocheso ea moralo o thata oa PCB

Ho blog ena, re tla hlahloba mekhoa le lipalo tse hlokahalang ho fumana ts'ebetso e futhumetseng ea meralo ea PCB e thata-flex.

Ha ho etsoa boto ea potoloho e hatisitsoeng (PCB), e 'ngoe ea lintlha tsa bohlokoa tseo baenjiniere ba lokelang ho li nahana ke ts'ebetso ea eona ea mocheso.Ka tsoelo-pele e potlakileng ea thekenoloji le tlhokahalo e tsoelang pele ea lisebelisoa tsa elektroniki tse sebetsang hantle le tse matla, ho qhala mocheso ho tsoa ho li-PCB e se e le phephetso e kholo. Sena ke 'nete haholo-holo bakeng sa meralo ea PCB e thata-fetohang e kopanyang melemo ea liboto tsa potoloho tse thata le tse tenyetsehang.

Ts'ebetso ea mocheso e bapala karolo ea bohlokoa ho netefatsa ho ts'epahala le ho phela nako e telele ha lisebelisoa tsa elektroniki.Mocheso o feteletseng o ka baka mathata a fapaneng, joalo ka ho hloleha ha likarolo, ho senyeha ha ts'ebetso, esita le likotsi tsa polokeho. Ka hona, ho bohlokoa ho lekola le ho ntlafatsa ts'ebetso ea mocheso oa li-PCB nakong ea moralo.

Mehato e meng ea bohlokoa ke ena ea ho bala ts'ebetso e futhumatsang ea meralo ea PCB e thata-flex:

1. Etsa qeto ea thepa ea mocheso: Ntlha ea pele, ke habohlokoa ho bokella tlhahisoleseding e hlokahalang mabapi le conductivity ea mocheso le mocheso o itseng oa mocheso oa thepa e sebelisoang ho meralo ea PCB e thata-flex.Sena se kenyelletsa likarolo tsa conductive, li-insulating layers, le lithako life kapa life tse eketsehileng tsa mocheso kapa li-vias. Litšobotsi tsena li etsa qeto ea bokhoni ba PCB ba ho felisa mocheso.

2. Thermal Resistance Calculation: Mohato o latelang o kenyelletsa ho bala ho hanyetsa mocheso oa lihlopha tse fapaneng le li-interfaces ka moralo o thata-flexible PCB.Ho hanyetsa mocheso ke tekanyo ea hore na thepa kapa sebopeho se tsamaisa mocheso hantle hakae. E hlahiswa ka diyuniti tsa ºC/W (Celsius per Watt). Ha mocheso o tlase o hanyetsa, ho molemo ho fetisa mocheso.

3. Etsa qeto ea litsela tsa mocheso: Fumana litsela tsa bohlokoa tsa mocheso ka meralo ea PCB e thata-flex.Tsena ke litsela tseo mocheso o hlahisoang ke mocheso o tsamaeang ka tsona. Ho bohlokoa ho nahana ka likarolo tsohle tse fehlang mocheso joalo ka li-IC, lisebelisoa tsa motlakase, le likarolo tse ling tse fehlang mocheso. Sekaseka tsela ea ho phalla ha mocheso ho tloha mohloling oa mocheso ho ea ho tikoloho e potolohileng 'me u hlahlobe phello ea lisebelisoa tse fapaneng le lihlopha tse fapaneng tseleng ena.

4. Ketsiso le tlhahlobo ea mocheso: Sebelisa software ea ho hlahloba mocheso ho etsisa mocheso oa mocheso ka moralo oa boto e thata-flex.Lisebelisoa tse 'maloa tsa software, tse kang ANSYS Icepak, SOLIDWORKS Flow Simulation kapa Mentor Graphics FloTHERM, li fana ka bokhoni bo tsoetseng pele ba ho etsa mohlala o nepahetseng le ho bolela esale pele boitšoaro ba mocheso. Lipapiso tsena li ka thusa ho tseba libaka tse chesang tse ka bang teng, ho lekola likhetho tse fapaneng tsa moralo le ho ntlafatsa ts'ebetso ea mocheso.

5. Ho ntlafatsa mocheso oa mocheso: Haeba ho hlokahala, mocheso oa mocheso o ka kenyelletsoa ho ntlafatsa ts'ebetso ea mocheso oa moqapi oa PCB o thata-flex.Licheso tsa mocheso li eketsa sebaka se ka holimo se fumanehang bakeng sa ho senya mocheso le ho ntlafatsa ho fetisa mocheso ka kakaretso. Ho ipapisitsoe le liphetho tsa patsiso, khetha moralo o nepahetseng oa sekoaelo sa mocheso, u ela hloko lintlha tse joalo ka boholo, thepa le sebopeho.

6. Lekola lisebelisoa tse ling: Lekola tšusumetso ea likhetho tse fapaneng tsa lisebelisoa mabapi le ts'ebetso ea mocheso oa meralo ea PCB e thata-flex.Lisebelisoa tse ling li tsamaisa mocheso hantle ho feta tse ling 'me li ka ntlafatsa haholo bokhoni ba ho qhala mocheso. Nahana ka likhetho tse kang li-ceramic substrates kapa thepa ea PCB e tsamaisang mocheso, e ka fanang ka ts'ebetso e ntle ea mocheso.

7. Teko le netefatso ea mocheso: Kamora hore moralo le papiso li phetheloe, ho bohlokoa ho lekola le ho netefatsa ts'ebetso ea mocheso oa 'nete.Setšoantšo sa PCB se thata-flex.Sebelisa khamera kapa li-thermocouples ho lekanya mocheso libakeng tsa bohlokoa. Bapisa litekanyo le likhakanyo tsa papiso 'me u phete moralo ha ho hlokahala.

Ka kakaretso, ho bala ts'ebetso ea mocheso oa liqapi tsa PCB tse thata-flex ke mosebetsi o rarahaneng o hlokang ho hlahlojoa ka hloko ka thepa ea thepa, ho hanyetsa mocheso le litsela tsa mocheso.Ka ho latela mehato e kaholimo le ho sebelisa software e tsoetseng pele ea ketsiso, baenjiniere ba ka ntlafatsa meralo ho fihlela phallo e nepahetseng ea mocheso le ho ntlafatsa ts'epo le ts'ebetso ea lisebelisoa tsa elektroniki ka kakaretso.

Hopola, tsamaiso ea mocheso ke karolo ea bohlokoa ea moralo oa PCB, 'me ho e hlokomoloha ho ka ba le liphello tse tebileng.Ka ho etelletsa pele lipalo tsa ts'ebetso ea mocheso le ho sebelisa mekhoa e nepahetseng, baenjiniere ba ka netefatsa bophelo bo bolelele le ts'ebetso ea lisebelisoa tsa elektroniki, esita le lits'ebetsong tse boima.
