7. Highleap Electronics: Reverse Engineering + PCB Production + Assembly

Highleap Electronics ifekitari yekugadzira nekugadzira maPCB. Kune electronic reverse engineering, izvi zvinokosha nekuti mafaira akagadzirwazve haangodhirowerwi kuti ataridzike zvakanaka chete - anosimbiswa pamidziyo yekugadzira nekugadzira iyo inovaka mabhodhi ekugadzira. Mupi wezvinhu asingakwanise kugadzira zvaanogadzira reverse engineering haakwanise kukupa vimbiso ine musoro yekuti mafaira ake achashanda.

Zvinosanganisirwa neKubatana Kusingaperi

• Unyanzvi hwemagetsi hwakakwana hwekudzosera kumashure: Kuongorora bhodhi → kuzivikanwa kwezvikamu → kuburitsa zvinhu nenzira yekufungidzira → Kugadziriswazve kweGerber layout → Kugadzirwa kweBOM → Kubviswa kwenetlist uye kusimbiswa kweLVS → Kusimbiswa kweprototype inoshanda
• Kugadzirwa kwePCB kwakabatanidzwa: Mabhodhi ekugadzira uye ekugadzira akavakwa mukati medu multilayer PCB kugadzira mutsetse — kusvika ku60 layers, HDI, rigid-flex, high-frequency substrate materials. Hapana kunonoka kwekukodzera kwefekitori — chinhu chimwe chete chakavaka patsva dhizaini ndicho chinovaka bhodhi.
• Kuungana kwePCB kwakabatanidzwa: SMT uye kuunganidza maburi mukati meimba uchishandisa BOM yakagadzirwazve uye data rekusarudza-ne-nzvimbo. Masevhisi egungano akazara kusanganisira AOI, X-ray test, uye functional examination bvunzo pane yega yega prototype proofing build.
• Kuonekwa kuri pachena uye mitengo: Mari yakazara yepurojekiti yakataurwa pakutanga, inotsanangurwa nekunyora. Hapana kuwedzerwa kwepakati pepurojekiti. Mafaira anounzwa mumafomu akajairwa anoshandiswa zvizere — achashanda kune chero fekitori inokodzera, kwete yedu chete. Haumbofi wakavharirwa mukati.
• Dziviriro yeNDA: Chibvumirano Chekusazivisa Nyaya Chakajairika chakaitwa bhodhi renyu risati rasvika — kwete mushure mekusvika.
