8 Layer ENIG FR4 Via-In-Pad PCB
Chovuta kwambiri kuwongolera dzenje la pulagi mu via-mu-pad ndi mpira wa solder kapena pad pa inki mu dzenje.Chifukwa cha kufunikira kogwiritsa ntchito kachulukidwe kakang'ono ka BGA (gulu lamagulu a mpira) komanso kachipangizo kakang'ono ka SMD chip, kugwiritsa ntchito ukadaulo wa thireyi kumachulukirachulukira.Kupyolera mu njira yodalirika yodzaza mabowo, ukadaulo wa ma plate hole utha kugwiritsidwa ntchito pakupanga ndi kupanga ma board a multilayer apamwamba kwambiri, ndikupewa kuwotcherera kwachilendo.Ma Circuits a HUIHE akhala akugwiritsa ntchito ukadaulo wa pa-pad kwa zaka zambiri, ndipo ali ndi njira yabwino komanso yodalirika yopanga.

Ntchito Ya Plug Hole
1.Letsani malata kuti asadutse pabowo la conduction kudzera pagawo lapamwamba panthawi ya soldering yoweyula
2.Pewani zotsalira zotuluka mu dzenje
3.Letsani mipira ya malata kuti isatuluke panthawi ya soldering yoweyula, zomwe zimapangitsa kuti pakhale nthawi yochepa
4.Letsani phala la solder kuti lisalowe mu dzenje, zomwe zimapangitsa kuwotcherera komanso kukhudza koyenera.
Ubwino Wa Via-In-Pad PCB
1.Kupititsa patsogolo kutentha kwa kutentha
2.The voteji kupirira mphamvu ya vias ndi bwino
3.Kupereka malo ophwanyika komanso osasinthasintha
4.Lower parasitic inductance
Ubwino Wathu
1. Fakitale yake, malo a fakitale 12000 square metres, fakitale yogulitsa mwachindunji
2. Gulu lazamalonda limapereka ntchito zogulitsiratu komanso zotsatsa pambuyo pake
3.Process-based processing of PCB data design data kuonetsetsa kuti makasitomala angathe kubwereza ndi kutsimikizira nthawi yoyamba
