Hobaneng u sebelisa FR4 ho etsa li-PCB tse phahameng tsa Tg?

Lisebelisoa tse ling li hloka hore PCB e mamelle mocheso o lekanyelitsoeng oa 200 ℃ kapa ho feta.Bakeng sa ts'ebetso e tšepahalang lits'ebetsong tse phahameng tsa mocheso, re hloka li-PCB tse inehetseng tse entsoeng ka lisebelisoa tse tsamaisoang ke ts'ebetso.Blog ena e etselitsoe ho u tseba ka PCB e le 'ngoe e inehetseng joalo, e bitsoang HIGH-TG.Tsenali-PCB tse phahamenge ka mamella mocheso o phahameng haholo oa phetoho ea likhalase tsa li-PCB ha e ntse e fana ka lintlha tse latelang:

1. Taolo e ntlafalitsoeng ea impedance

2. Tsamaiso e ntle ea mocheso

3. Ho monya mongobo o tlase

4. Ts'ebetso e tsitsitseng

FR4 - Lintho tse ratoang bakeng sa li-PCB tse phahameng tsa Tg

Bakeng sa lits'ebetso tse fapaneng tsa mocheso o feteletseng, li-PCB tse phahameng tsa Tg li etsoa ho sebelisoa li-substrates tsa FR-4.Fr-4 ke khalase e thibelang mollo fiber e matlafalitsoeng ea epoxy e lulang e le lipotoloho tse ngata tsa lamination, ho sebetsana le PCB e rarahaneng le ho lumella tjheseletsa e se nang lead.Li-substrates tse tloaelehileng tsa FR-4 li kenyelletsa PTFE e hloekileng, PTFE e tletseng ceramic, le thermosetting hydrocarbon substrates.Tse latelang ke thepa e khethehileng ea FR-4 substrate e etsang hore e be e loketseng bakeng sa li-PCB bakeng sa likopo tse hlokang.

1. Ts'ebetso e ntle ea motlakase.

2. E ka mamella ho cheka ho khethehileng le ho rala ka lesoba (PTH) ho lokisoa.

3. Excellent plating ka ho tšepahala lesoba.

4. Litšenyehelo li batla li le tlaase.

5. Ntho e tsitsitseng ea ho senya (Df) ha e bapisoa le lisebelisoa tse ling tse tloaelehileng tsa PCB.

6. Ho hanyetsa lik'hemik'hale tse babatsehang

7. E loketse bakeng sa moralo oa PCB o hlokang taolo e tiileng ea impedance

8. E thibelang ho thothomela, e thibelang ho thothomela le e thibelang malakabe.

Ha ho nahanoa ka ts'ebetso ea eona e ikhethang tsamaisong ea mocheso, li-PCB tsa FR-4 High Tg li khethiloe ka bongata bakeng sa lits'ebetso tsa likhomphutha, polokelo le lisebelisoa, lisebelisoa tsa elektronike tsa bareki, litsamaiso tsa marang-rang le tsa puisano, sebaka sa sefofane le Ts'ireletso, bongaka, indasteri le lisebelisoa, le liindasteri tsa likoloi le tsa elektronike.Indasteri ea lipalangoang.

Khetha lisebelisoa tse nepahetseng ho fihlela liphetho tse lakatsehang
