Menene ainihin aikin haɗin allo-da-board?

1. Mechanical Properties

Dangane da aikin haɗin gwiwa, shigar da ƙarfin janyewa shine muhimmin kayan inji. Shigarwa da ja da ƙarfi sun kasu zuwa shigar da ƙarfi da ja da ƙarfi (ƙarfin ja kuma ana kiransa da ƙarfi), kuma buƙatun biyun sun bambanta. A cikin ma'auni masu dacewa, akwai mafi girman shigar da karfi da kuma mafi ƙarancin tanadin ƙarfi na rabuwa, wanda ke nuna cewa daga ra'ayi na amfani, ƙarfin shigarwa ya kamata ya zama ƙananan (don haka akwai ƙananan ƙarfin shigar da LIF kuma babu tsarin shigar da ƙarfin ZIF). , kuma idan ƙarfin rabuwa ya yi ƙanƙara, zai shafi amincin haɗin gwiwa.

Wani muhimmin kayan aikin injiniya shine rayuwar inji na mai haɗin jirgi-da-board. Rayuwar injina haƙiƙa ƙaƙƙarfan jigo ce, wacce ake kira aikin injiniya a ma'aunin GB5095 na ƙasa. Yana dogara ne akan shigarwa ɗaya da cirewa ɗaya azaman sake zagayowar, kuma ko mai haɗin haɗin zai iya kammala aikin haɗin gwiwa kullum (kamar ƙimar juriyar lamba) bayan an yi amfani da ƙayyadaddun shigarwa da sake zagayowar cirewa azaman tushe don kimantawa.

Ƙarfin shigarwa da rayuwar inji na mai haɗin jirgi-zuwa-board yana da alaƙa da tsarin lamba (matsi mai kyau) da ingancin shafi (madaidaicin juzu'i) na ɓangaren lamba da daidaiton girman (digiri na daidaitawa) na ɓangaren lamba.

2. Ayyukan lantarki

Ya ƙunshi juriya na lamba, juriya na rufi, ƙarfin halin yanzu da wutar lantarki

Juriya na tuntuɓa: Babban mai haɗa wutar lantarki ya kamata ya kasance yana da ƙanƙara kuma tsayayyiyar juriyar lamba. Masu haɗin haɗin suna da juriyar lamba daga ƴan milliohm zuwa dubun milliohm.

Juriya na insulation: Ma'auni na aikin insulation tsakanin lambobin haɗin lantarki da tsakanin lambobi da gidaje, a cikin tsari na ɗaruruwa zuwa dubban megohm.

Ƙarfin wutar lantarki ko juriya na ƙarfin lantarki: Ikon jure wa ƙimar gwajin gwajin tsakanin masu haɗa lambobin sadarwa ko tsakanin lambobin sadarwa da mahalli ya dogara da rata tsakanin da'irori (wato, nisa tsakanin lambobin sadarwa da nisan creepage) da kayan rufin. ana amfani da shi a cikin mahaɗin
