Kuti uderedze kusanzwisisika uye kudzivirira kudzokorora mashoko asina kufanira, sanganisira ruzivo runotevera muRFQ package:

• Mafaira eGerber kana ODB++ uye NC Drill Data: Isawo gwaro rakakodzera rekugadzirisa zvinhu kuitira kuti mutengesi agone kuongorora zvidimbu zvemhangura, maburi nedata rekugadzira zvinhu.
• Kudhirowa Kwekugadzira uye Kuunganidza Zvinhu Zvakafanana: Magiredhi ezvinhu, ukobvu hwakapedzwa, huremu hwemhangura, kuvakwa kwe dielectric uye chero nzvimbo dzakasiyana dzakasimba uye dzinochinjika.
• Zvinodiwa pakuvaka nekukombamisa: Tsvaga kuvakwa kwakasimba, kunochinjika kana kunochinjika, huwandu hwezvikamu zvichienderana nenzvimbo, kukotama kusingachinjiki kana kunochinjika, nharaunda shoma yekukombama, chifukidziro uye zvinodiwa zvekusimba.
• Zvimiro Zvishoma uye Zvinodiwa Nekushandisa: Tsanangura nzvimbo, nzvimbo yekuboorera uye saizi yegomba rakapedzwa, mavhairasi asina kuvharwa/akavigwa, mavhairasi ari mupad uye kuvharwa kana kuzadza kunodiwa.
• Maitiro Akakosha uye Kupedzisa Kwepamusoro: Nyora goridhe rakasimba rakasarudzwa, ENEPIG, resin filling, backdrilling, edge plating, maburi, coverlay openings, special glues nezvimwe zvinhanho zvisiri zvemhando yepamusoro.
• Zvinodiwa zveMagetsi neHunhu: Taura kirasi yekugamuchira inoshanda, kudzorwa kweimpedance, kuyedzwa kwemagetsi, makuponi, mishumo uye kurondwa kwedata kana zvichidikanwa.
• Huwandu uye Kutumirwa: Kumbira mhando dzakafanana dzezvigadzirwa uye huwandu hwezvigadzirwa, uye taura zuva raunoda kusvika uye kwaunoda kuenda.
• Dzimwe Nzira Dzakatenderwa: Tsvaga shanduko dzezvinhu kana magadzirirwo ayo mainjiniya angafunga nezvawo kana vachigona kuderedza mutengo pasina kukanganisa zvinodiwa.

Usati waisa odha, simbisa nekunyora kuti quotation yacho inosanganisira chii, kuti ndeapi magadzirirwo asina kuongororwa, kana maitiro ese akakosha akafukidzwa uye kuti nguva yakatarwa yekutanga inotanga rini. Kana shanduko inokurudzirwa ichikanganisa mashandiro emagetsi, kukodzera kwemuchina, kuunganidza kana kuvimbika, tsvaga mvumo yemuridzi wedhizaini pane kugamuchira kutsiva kwakanyarara.

Kana purojekiti ichidawo kubatanidzwa, ipai BOM, data rekuisa, mifananidzo yekubatanidza uye zvinodiwa zvekuyedza zvekotesheni yePCBA yakasiyana kana yakabatanidzwa. Mutengo wePCB usina bhodhi 8 hausanganisire otomatiki zvikamu kana kubatanidzwa kweSMT. Kana purojekiti ichida kugadzirwa uye kuiswa kwezvikamu, chiyero chinodiwa chinogona kuongororwa kuburikidza nemasevhisi ePCB ekugadzira zvigadzirwa zvemagetsi , kungave kwakasiyana kana pamwe chete nezvinodiwa zvekugadzira bhodhi.

Mutengo wePCB wakavimbika hausi nhamba yakaderera chete. Mutengo wekuvaka kwakakodzera—kwakasimba, kunochinjika kana kuchinjika—wakaongororwa zvichienderana nezvinodiwa uye unogona kugadzirwa nekuendeswa nenguva chaiyo.
