Yuav ua li cas xaiv polyimide daim kab xev kom yog?
Xaiv txoj cai polyimide daim kab xev yog qhov tseem ceeb rau kev ua tiav ntawm daim ntawv thov thiab yuav tsum muaj kev xav:
Qib kub tsis kam:
Clearly define the maximum continuous operating temperature and peak temperature in the application. Silicone series usually have higher temperature resistance (>260 Degree).
Hom nplaum:
Silicone Series: Ultra- qhov chaw nyob kub, cov tshuaj viscire zoo, yooj yim los kua muag (zoo ua haujlwm hnyav). Haum rau kev tiv thaiv vuam thiab huv ib puag ncig.
Acrylic: High Bonding lub zog, zoo hnyav tiv thaiv, kuj yog tus nqi qis. Haum rau cov ntawv thov uas xav tau kev sib raug zoo thiab qhov ntsuas kub me me tiv thaiv (xws li coil kho).
Substrate Thickness: cov tuab tuab xws li 25μm (13mil), 50μm (2μm (2mil), thiab 75μm (3mil). Thicker tuab ua txhais tau tias zoo dua cov tshuab ua kom muaj zog thiab rwb thaiv tsev; thinner thickness txhais tau tias zoo dua yooj, haum rau nkhaus lossis cov haujlwm tsis zoo.
Adhesion (tev quab yuam): Xaiv raws li saum npoo ntawm adherend thiab qhov xav tau kev txhim kho lub zog. Muaj los ntawm ultra -} Tsis yooj yim tshem tawm yam tsis muaj seem) rau ultra- siab viscosity (ruaj khov kho).
Cov Hluav Taws Xob Hluav Taws Xob: Rau Kev Siab Hluav Taws Xob: Ua Siab Zoo}}}}}}}} Lub zog delicage) thiab voltistivity qhia.
Tshuaj lom neeg thaj chaw: dab tsi ntawm cov kuab tshuaj, roj, lossis tshuaj lom neeg koj kis tau? Xaiv cov nplaum nrog kev ua haujlwm zoo.
Xim: tus qauv yog amber (xim av). Kuj tseem muaj cov xim tshwj xeeb xws li dub (lub teeb - shielding, UV {{ove} tiv taus) thiab dawb (siab dua).
Qhov dav thiab ntev: Txheem yob lossis kev cai tuag {{luas} txiav cov duab.
Daim Ntawv Pov Thawj Yuav Tsum: xws li UL ntawv pov thawj (Rougation System), ROHS, ncav cuag, thiab lwm yam.
Tshwj xeeb yuav tsum tau ua: xws li hluav taws xob tsis kam, ultra- Cov qauv muaj), thermal conductivity (tshwj xeeb sau qauv), thiab lwm yam.
