Menene PCB mai girman Tg?

Babban PCB mai girman Tg wani allo ne da aka buga da'ira mai zafin canzawar gilashi (Tg) na 170°C ko sama da haka, wanda ya bambanta shi da daidaitattun PCBs na FR-4 (Tg 130–140°C) da kuma PCBs na matsakaicin Tg (150–160°C). Tg yana wakiltar zafin da substrate ke canzawa daga yanayin "gilashi" mai tauri zuwa yanayin laushi, mai roba. PCBs masu girman Tg suna kiyaye ƙarfin injina, kwanciyar hankali na girma, da aikin lantarki a yanayin zafi mai tsayi, wanda hakan ke sa su zama mahimmanci ga aikace-aikace masu tsananin buƙatun zafi.

Mahimman Bayanan Fasaha

-Juriyar Zafin Jiki: Yana aiki da aminci har zuwa 130–150°C (20–25°C ƙasa da Tg), wanda ya dace da soldering ba tare da gubar ba (zafin sake kwarara har zuwa 260°C).
-Abubuwan da Aka Haɗa: Yana amfani da resin epoxy da aka gyara ko kuma abubuwan da aka cika da yumbu don ƙara juriya ga zafi.
-Matsakaicin Tg:
+ Madaidaicin FR-4: Tg 130-140°C
+Matsakaici-Tg: 150–160°C
+Babban Tg: ≥170°C (misali, 170°C, 180°C, 200°C)

Bin Dokoki Ba Tare da Guba Ba: Yana jure wa sake yin solder a zafin jiki na 240-260°C, wanda yake da mahimmanci ga masana'antar da ta dace da RoHS.

Ingantaccen Aikin Inji da Wutar Lantarki

Daidaito na Girma: Ƙarancin faɗuwar zafi (CTE) yana rage warping a cikin zane-zane masu launuka da yawa.
Amincin PTH: Ƙarfi ta hanyar mannewa a kan rufi yana rage haɗarin fashewa a cikin zagayowar zafi.

Juriyar Sinadarai da Danshi

Kwanciyar hankali mai yawa: Rage shan ruwa (≤0.15%) idan aka kwatanta da FR-4 na yau da kullun, yana hana lalata ruwa a yanayin danshi.
Juriyar Sinadarai: Yana jure wa lalacewa daga kwararar ruwa, masu tsaftacewa, da sinadarai na masana'antu.

Daidaituwa da Multilayer da HDI: Yana tallafawa ƙananan tsare-tsare masu ƙarfi da ƙarfi ba tare da wuraren zafi ba.
Tallafin Kayan Haɗin Kai: Yana haɗuwa da aluminum ko cores na yumbu don ingantaccen sarrafa zafi.
