Kungani usebenzise i-FR4 ukwenza ama-Tg PCB aphezulu?

Ezinye izinhlelo zokusebenza zidinga i-PCB ukuthi imelane nezinga lokushisa eliphakeme elingu-200℃ noma ngaphezulu.Ukuze usebenze okuthembekile ezinhlelweni zokushisa okuphezulu, sidinga ama-PCB azinikele akhiwe kusetshenziswa izinto eziqhutshwa ukusebenza.Le bhulogi iklanyelwe ukukujwayeza nge-PCB eyodwa ezinikezele, ebizwa nge-HIGH-TG.LeziInani eliphakeme kakhulu lama-PCBingamelana nezinga lokushisa eliphezulu kakhulu lengilazi lama-PCB ngenkathi inikeza izici ezilandelayo:

1. Ukulawulwa kwe-impedance okuthuthukisiwe

2. Ukuphathwa okungcono kwe-thermal

3. Ukumuncwa komswakama okuphansi

4. Ukusebenza okungaguquki

FR4 - Izinto ezikhethwayo zama-Tg PCB aphezulu

Kuzinhlelo zokusebenza zebanga lokushisa okwedlulele, ama-Tg PCB aphezulu akhiqizwa kusetshenziswa ama-substrates e-FR-4.I-Fr-4 iyi-fiber yengilazi ebambezela ilangabi eqiniswe yi-epoxy ehlala imijikelezo eminingi ye-lamination, ukuphatha okuyinkimbinkimbi kwe-PCB futhi ivumela ukushisela okungenamthofu.Ama-substrates e-FR-4 avamile afaka i-PTFE emsulwa, i-PTFE egcwele i-ceramic, kanye nama-thermosetting hydrocarbon substrates.Okulandelayo yizici ezikhethekile ze-FR-4 substrate ezenza ilungele ama-PCB kwizicelo ezifunayo.

1. Ukusebenza kahle kagesi.

2. Ingakwazi ukumelana nokubhoboza okukhethekile nokucwecwa ngembobo (PTH) ukulungiswa.

3. Excellent Plating ngokusebenzisa imbobo ukwethembeka.

4. Izindleko ziphansi.

5. I-stable dissipation factor (Df) uma iqhathaniswa nezinye izinto ezijwayelekile ze-PCB.

6. Ukumelana kwamakhemikhali okuhle kakhulu

7. Ifanele idizayini ye-PCB edinga ukulawula okuqinile kwe-impedance

8. I-Shockproof, i-shockproof kanye ne-flame retardant.

Uma kucatshangelwa ukusebenza kwayo okuyingqayizivele ekuphathweni kwe-thermal, ama-FR-4 High Tg PCB akhethelwe kabanzi izinhlelo zokusebenza zekhompuyutha, ukugcinwa kanye nama-peripherals, ama-electronics abathengi, amasistimu enethiwekhi nezokuxhumana, i-aerospace & Defense, yezokwelapha, i-Industrial & Instrumentation, kanye nezimboni zezimoto neze-electronics.Imboni yezokuthutha.

Khetha izinto ezifanele ukuze uthole imiphumela oyifunayo

Phakathi kwezinhlobo zezinto ezitholakalayo ze-FR-4, kubalulekile ukukhetha into efanele yezidingo zohlelo lokusebenza, njengoba inquma ukuzinza nokusebenza kahle kwengxenye yokugcina.Izinto ezifana nemvume ye-dielectric, i-coefficient yokulahlekelwa, i-thermal conductivity, izinga lokushisa lokushintsha, i-coefficient of thermal expansion (CTE), izakhiwo zikagesi, njll., kufanele zicatshangelwe ngaphambi kokukhetha ama-substrates e-FR-4 ohlelo lwakho lokusebenza.Uma udidekile mayelana nohlobo lwezinto ze-FR-4 ongakhetha kuzo, cabanga ukusebenza nomkhiqizi we-PCB onesipiliyoni sokuhlinzeka ngama-Tg PCB aphezulu ezimbonini ezihlukahlukene.I-RigiFlex Technologies ingenye eyaziwa kakhuluAbakhiqizi be-PCBemakethe futhi banokuhlangenwe nakho okusebenzayo ekuletheni ama-Tg PCB aphezulu ngezindlela ezihlukahlukene zokucushwa.Cela isilinganiso esiphezulu se-tg PCB manje!
