A yau, za mu ci gaba da koyo game da abubuwan da ke ƙayyade yawan yadudduka da aka ƙera PCB don samun.

A yau za mu gaya muku menene ma'anar kuma menene mahimmancin "Layer" a masana'antar PCB.

A yau, bari mu dubi kayan gwaji a masana'antar mu waɗanda ke ba da tabbacin ingancin samfuran PCB da muke samarwa.

A kan 15th Oct. Abokin ciniki form NZ zo ziyarci mu factory a cikin ShenZhen.

Bari mu ci gaba da koyon tsari game da sanya guntu. 1. Karɓar Chips tare da Bump 2. Chip Orientation 3. Chip Daidaita 4. Chip bonding 5. Maimaitawa 6. Wanka 7. Rashin cikawa 8. Yin gyare-gyare

Bari mu ci gaba da koyon tsari game da ƙirƙirar kumbura. 1. Wafer mai shigowa da tsafta 2. PI-1 Litho: (Hoto na Farko na Farko: Hoton Rufin Polyimide) 3. Ti / Cu Sputtering (UBM) 4. PR-1 Litho (Hoto na Biyu na Biyu: Hoton Hoton hoto) 5. Sn-Ag Plating 6. Tashar PR 7. UBM Etching 8. Maimaitawa 9. Chip Sanya

A cikin labarin da ya gabata, mun gabatar da abin da ake kira flip chip. Don haka, menene tsarin tafiyar da fasahar juzu'i? A cikin wannan labarin labarai, bari mu yi nazari daki-daki, ƙayyadaddun tsarin tafiyar da fasahar juye guntu.

Lokaci na ƙarshe da muka ambata “chip guntu” a cikin tebur ɗin fasaha na marufi, to menene fasahar juzu'i? Don haka bari mu koyi hakan a cikin sabon yau.

Anan akwai tebur na marufi na Chip daidai nau'ikan nau'ikan madauri

Kamar yadda aka nuna a cikin adadi da ke sama, sarƙoƙi Substrater sun kasu kashi uku: Organic Substrates, da substrates, da substrater.

A yau, zan gaya muku menene ma'anar TG, kuma menene fa'idodin amfani da babban TG PCB.

Yau Bari muyi magana game da raka'a guda biyar na PCB da menene ma'anar su. 1.Dielectric Constant (darajar DK) 2.TG (Glass Transition Temperature) 3.CTI (Kwantancin Bibiya) 4.TD (Thermal Decomposition Temperature) 5.CTE (Z-axis) - (Coefficient of thermal Expansion a cikin Z-direction)
