Multilayer circuit boards ine marudzi akawanda ekushanda layers, akadai se: protective layer, silk screen layer, sign layer, internal layer, etc. Unoziva zvakawanda sei pamusoro pezvikamu izvi? Mabasa emutsetse wega wega akasiyana, ngatitarisei kuti mabasa edanho rega rega anofanirwa kuitei!

Dziviriro layer: inoshandiswa kuve nechokwadi chekuti nzvimbo dziri pabhodhi redunhu dzisingade tin plating hadzina kuvharwa, uye PCB redunhu bhodhi rinoitwa kuve nechokwadi chekuvimbika kwekushanda kwebhodhi redunhu. Pakati pavo, Paste Yepamusoro uye Pazasi Paste ndiyo yepamusoro solder mask layer uye yepasi solder mask layer, zvichiteerana. Yepamusoro Solder uye Yepasi Solder ndiyo solder paste yekudzivirira layer uye yepasi solder paste yekudzivirira layer, zvichiteerana.

Silk screen layer - inoshandiswa kudhinda nhamba ye serial, nhamba yekugadzira, zita rekambani, logo pattern, nezvimwe zvezvikamu pabhodhi redunhu.

Chiratidzo chechiratidzo - chinoshandiswa kuisa zvikamu kana wiring. Protel DXP inowanzo ine makumi matatu epakati akaturikidzana, anoti Mid Layer1~Mid Layer30, iyo yepakati layer inoshandiswa kuronga mitsetse yechiratidzo, uye kumusoro nepasi pasi kunoshandiswa kuisa zvikamu kana mhangura.

Yemukati dhizaini - inoshandiswa sechiratidzo chekufambisa dhizaini, Protel DXP ine gumi nematanhatu mukati.
