Yadda za a inganta aikin mannewa saman na fim din polyimide

Fim ɗin Polyimide shine samfurin fim ɗin da ya shahara sosai a yanzu, tare da aikace-aikace da yawa da kyakkyawan aiki. Koyaya, yayin amfani, wasu abokan ciniki da abokai za su gamu da matsaloli tare da aikin mannewa. Don haka, yadda za a inganta aikin adhesion na fim ɗin polyimide? Ƙwararrun masana’antun za su ba da amsar a ƙasa, ku zo ku gani.

Polyimide fim (PI) wani abu ne na musamman na polymer roba tare da kyawawan kayan aikin jiki da na inji da kuma kyakkyawan kwanciyar hankali na lantarki da sinadarai. Ana amfani dashi ko’ina a cikin sararin samaniya, rufin lantarki, microelectronics da sauran masana’antu (a matsayin dielectric spacer, Layer na kariya, da tushe na bangon ƙarfe). Saboda fim ɗin PI yana da ƙasa mai santsi, ƙarancin aiki na sinadarai, da ƙarancin mannewa ga foil ɗin ƙarfe (bayan aluminum, foil jan ƙarfe, da sauransu). ), fuskar fim ɗin PI yana buƙatar kulawa ko gyara don inganta mannewa na PI.

A halin yanzu, a cikin dukkanin jiyya da hanyoyin gyare-gyare na fim din polyimide, saboda tsari da abubuwan farashi, an yi nazarin maganin acid-base. Wasu takardun sun ba da rahoton cewa irin wannan cigaba na wettability da Hanyar mannewa, amma babban aikin samfurori na masana’antu bayan jiyya ba shi da rahotanni da hankali.

Ta hanyar zalunta fuskar fim din polyimide tare da maganin oxalic acid, sodium hydroxide da ruwa mai tsafta, ba tare da tasiri mai kyau da kuma kayan aikin injiniya na ciki na fim din polyimide ba, an yi nazarin tasirin nau’o’in acid-base daban-daban da kuma daidai lokacin jiyya. Bayan gyaran fuska, aikin mannewa na fim din polyimide yana shafar, kuma sakamakon aikace-aikacen gyaran fuska na fim din polyimide shine kamar haka:

1. A cikin saurin samarwa na yanzu, canza canjin acid-base maida hankali ba shi da wani tasiri a kan kayan aikin injiniya na fim din polyimide bayan jiyya.

2. Ana iya gani daga halayen ƙwayar ƙwayar cuta ta atomatik cewa ƙarancin fim ɗin polyimide yana ƙaruwa sosai bayan lalata tushen acid.

3. Bayan maganin acid-base, a ƙarƙashin wannan ƙwayar acid-tushe, ƙarfin kwasfa na PI yana ƙaruwa tare da tsawo na lokacin jiyya; a irin wannan saurin abin hawa, ƙarfin peeling yana ƙaruwa daga 0.9Kgf / cm tare da haɓaka ƙwayar acid-tushe zuwa 1.5Kgf / cm.

4. Ana inganta tsaftacewar PI membrane surface sosai, wanda ke warware ingancin da samar da abubuwan da suka haifar da datti na abokan ciniki.
