Chii zvachoPCBmaitiro ekuongorora chitarisiko?
1. Packaging: isina ruvara air bag vacuum packaging, ine desiccant mukati, yakanyatsorongedzwa
2. Silk screen printing: Sirika screen kudhindwa kwemavara nezviratidzo zviri pamusoro pePCB kunofanirwa kuve kwakajeka uye kuri pachena, uye ruvara runofanirwa kuenderana nemirairo, pasina kudhindwa kudzokororwa, kushaikwa kudhindwa, kudhindwa kwakawanda, kutsauka kwenzvimbo, uye. kusadhinda zvisirizvo.
3. Bhodhi kumucheto kwebhodhi repamusoro: Tarisa kana pane mavara, sundries, makomba, tin slag residues pamusoro pePCB;ingave iyo bhodhi yepamusoro yakakweshwa uye yakaratidzwa kune substrate;Kune ma layers, etc.
4. Makondakita: Hapana dunhu ripfupi, dunhu rakavhurika, mhangura yakafumurwa mukondakita, foil yemhangura inoyangarara, wiring yekuwedzera, etc. Mapedhi: Mapedhi anofanirwa kuvharwa zvakaenzana, uye mhangura haifanirwe kufumurwa, kukuvadzwa, kupepetwa, kuremara, zvichingodaro. . Chigunwe chegoridhe: kupenya, mabumps/bubbles, mavara, foil yemhangura inoyangarara, kupfekedzwa pamusoro, maburrs, plating adhesion, nezvimwe.
5. Makomba: Tarisa pane yapfuura batch yemaPCB akanaka kuti utarise kana pasina maburi ekuchera, maburi akawanda, maburi akavharika, uye kutsauka kwegomba.Solder mask: Unogona kushandisa bhodhi yekushambidza mvura kuti uipukute panguva yekuongorora kuti utarise kunamatira kwayo, kutarisa kuti ichawa, kana pane mabhubhu, kana pane chiitiko chekugadzirisa, etc. Muvara we solder mask inofanira kusangana nemitemo. .
6. Kuisa chiratidzo: hunhu, chirevo chekutsvaga, shanduro yemuenzaniso, moto wemoto / UL.chiyero, chitsauko chekuyedza magetsi, zita remugadziri, zuva rekugadzira, nezvimwe.
7. Saizi kuyerwa: kuyera kana saizi chaiyo yePCB iri kuuya yakatsanangurwa muhurongwa.
Warpage kana curvature kuongorora:
8. Solderability bvunzo: Tora chikamu chePCB chekutengesa chaiko, uye tarisa kana zvikamu zvinogona kutengeswa nyore.
