Kutheni usebenzisa iFR4 ukwenza iiTg PCB eziphezulu?

Ezinye izicelo zifuna iPCB imelane nobushushu obuphezulu obuyi 200℃ okanye ngaphezulu.Ukusebenza okuthembekileyo kwizicelo zobushushu obuphezulu, sifuna iiPCB ezizinikeleyo ezenziwe kusetyenziswa izinto eziqhutywa yintsebenzo.Le bhlog yenzelwe ukukuqhelanisa nePCB enye ezinikeleyo, ebizwa ngokuba yi-HIGH-TG.EziiiPCBs eziphezulu zetginokumelana nobushushu obuphezulu beglasi yokutshintsha kweePCB ngelixa ibonelela ngezi zinto zilandelayo:

1. Ukuphuculwa kolawulo lwe-impedance

2. Ulawulo olungcono lwe-thermal

3. Ukufunxa ukufuma okuphantsi

4. Ukusebenza okufanayo

I-FR4 - Izinto ezikhethwayo kwii-PCB ze-Tg eziphezulu

Ukusetyenziswa koluhlu lobushushu obugqithisileyo, ii-PCB eziphezulu ze-Tg zenziwe kusetyenziswa i-FR-4 substrates.I-Fr-4 yifayibha yeglasi ebuyisela idangatye eyomeleziweyo ye-epoxy ehlala kwimijikelo emininzi ye-lamination, ukuphatha i-PCB entsonkothileyo kwaye ivumela ukuwelda ngaphandle kwelothe.Iisubstrates ze-FR-4 eziqhelekileyo ziquka i-PTFE esulungekileyo, i-PTFE ezaliswe nge-ceramic, kunye ne-thermosetting hydrocarbon substrates.Oku kulandelayo ziipropati ezikhethekileyo ze-FR-4 substrate ezenza ukuba zilungele ii-PCBs ezifuna izicelo.

1. Ukusebenza kombane okugqwesileyo.

2. Inokumelana nokugrumba okukhethekileyo kunye nokucwenga ngomngxuma (PTH) ukulungiswa.

3. Ukucwenga okugqwesileyo ngokuthembeka komngxuma.

4. Iindleko ziphantsi.

5. I-stable dissipation factor (Df) xa kuthelekiswa nezinye izinto eziqhelekileyo ze-PCB.

6. Ukumelana neekhemikhali ezigqwesileyo

7. Ifanelekile kuyilo lwePCB olufuna ulawulo olungqongqo lwe-impedance

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

Ukuqwalasela ukusebenza kwayo okuyingqayizivele kulawulo lwe-thermal, i-FR-4 High Tg PCBs zikhethwa ngokubanzi kwizicelo kwi-computing, ukugcinwa kunye neeperipherals, i-electronics yabathengi, i-networking kunye neenkqubo zonxibelelwano, i-aerospace & Defense, unyango, i-Industrial & Instrumentation, kunye ne-automotive & electronics industries.Ishishini lezothutho.

Khetha izixhobo ezifanelekileyo ukufezekisa iziphumo ezifunwayo

Phakathi kweentlobo zezinto ezikhoyo ze-FR-4, kubalulekile ukukhetha izinto ezifanelekileyo kwiimfuno zesicelo, njengoko kugqiba ukuzinza kunye nokusebenza ngokufanelekileyo kwecandelo lokugqibela.Izinto ezifana nemvume ye-dielectric, i-coefficient yokulahlekelwa, i-thermal conductivity, ukushisa kwenguqu, i-coefficient of thermal expansion (CTE), izakhiwo zombane, njl., Kufuneka ziqwalaselwe ngaphambi kokukhetha i-FR-4 substrates kwisicelo sakho.Ukuba ubhidekile malunga nohlobo lwe-FR-4 imathiriyeli onokuthi uyikhethe, cinga ukusebenza nomvelisi we-PCB onamava ekuboneleleni ngee-Tg eziphezulu ze-PCB kumashishini ahlukeneyo.I-RigiFlex Technologies yenye yezona zidumileyoAbavelisi bePCBkwimarike kwaye banamava ezandla ekuhambiseni ii-PCB zeTg eziphezulu kwiindidi ezahlukeneyo zoqwalaselo.Cela ikhowuti ephezulu ye-tg yePCB ngoku!
