4. Kabowo kakang'ono: 0.1mm
4-wosanjikiza PCB ili ndi kabowo kakang'ono kakang'ono ka 0.1 mm, kuwonetsetsa kuyika bwino kwa zigawo, potero kumawonjezera magwiridwe antchito ndi kudalirika kwa magalasi anzeru a VR.

5. Makulidwe amkuwa: 12um
Kuyendetsa bwino kwamagetsi ndikofunikira pakutumiza kwa data pazida za VR.PCB yosinthika ya 4-wosanjikiza ili ndi makulidwe amkuwa a 12um, omwe amapereka kufalikira kwazizindikiro koyenera ndikuwonetsetsa kuyanjana kosasinthika pakati pa wogwiritsa ntchito ndi dziko lenileni.

6. Chowotcha moto: 94V0
Popanga zida zamagetsi, chitetezo ndichofunika kwambiri.PCB yosinthika ya 4-wosanjikiza ili ndi mulingo wapamwamba wa retardancy ndipo imakwaniritsa mulingo wokhazikika wa 94V0, kuwonetsetsa chitetezo ndi kudalirika kwa magalasi anzeru a VR.

7. Chithandizo chapamwamba: kumizidwa golide
Chithandizo chapamwamba cha PCB chimagwira ntchito yofunika kwambiri pakuwonetsetsa kulumikizana kodalirika.4-wosanjikiza flex PCB imakhala ndi golide womiza, chithandizo chapamwamba kwambiri chomwe chimawonjezera kusungunuka ndikulepheretsa okosijeni, kupititsa patsogolo magwiridwe antchito komanso moyo wautali.

8. Kukana kuwotcherera mtundu: wakuda
Ndi mtundu wake wakuda wakuda, 4-layer Flex PCB imasakanikirana bwino ndi kukongola kwa magalasi anzeru a VR, kumapangitsa chidwi chake.

9. Kuuma: chipolopolo chachitsulo, FR4
4-wosanjikiza kusinthasintha PCB amapereka bwino bwino pakati kusinthasintha ndi kuuma.Imagwiritsa ntchito chipolopolo chachitsulo ndi zinthu za FR4 kuti ipereke kulimba kofunikira kuti ithandizire zigawo zambiri ndikusunga kusinthasintha komwe kumafunikira magalasi anzeru a VR.
10. Ntchito: VR anzeru magalasi
Kugwiritsa ntchito kwa 4-layer flexible PCB mu VR magalasi anzeru ndikusintha.Ma PCB awa amathandizira kuphatikiza kosasinthika kwa magawo osiyanasiyana kuti apereke zochitika za VR zozama komanso zochititsa chidwi kwa ogwiritsa ntchito padziko lonse lapansi.
