Txheeb xyuas daim kab xev kub
Polyimide siab kub daim kab xev
(1) Cov tsos thiab saj;
(2) Cov seem tom qab qhov hluav taws kub thiab hlawv;
(3) Qhov ntsuas kub tiag tiag, tom qab qhov kub siab ntawm 260 °, xyuas seb puas muaj cov kua nplaum seem, ntsws me me, thiab lwm yam.
Polyimide daim kab xev kub tuaj yeem hloov kho raws li cov neeg siv khoom' tiv thaiv qhov xav tau hluav taws xob. Cov yeeb yaj kiab polyimide, uas yog tshwj xeeb kho cov khoom siv hluav taws xob kub, yog cov khoom siv hauv paus, uas muaj rwb thaiv tsev zoo, hnav tsis kam, kua qaub thiab alkali tsis kam, thiab tuaj yeem tiv taus qhov kub siab ntawm 300 degrees/10 feeb, thiab tuaj yeem siv rau ntev heev ntawm 180 degrees. Qhov ntev ntawm cov khoom yog 33M, thiab qhov dav tuaj yeem txiav txim siab faib ua ntau qhov sib txawv ntawm cov xim daj. Daim kab xev kub cov khoom no muaj cov khoom siv hluav taws xob zoo heev, rwb thaiv tsev siab, tiv taus kub, tiv taus kub tsis txias, kua qaub thiab alkali tsis kam, tsis muaj hluav taws xob zoo, cov cuab yeej siv zoo, puas txhuam, tiv taus kua muag, kho tshwj xeeb nplaum, muaj zog nplaum, thiab nws yuav Daim npog qhov ncauj tsis tso cov kua nplaum uas seem.
Polyimide siab kub daim kab xev yog dav siv rau kev tiv thaiv kab laug sab, kev tiv thaiv kub thiab kev sib txuas ntawm cov hloov pauv; cov khoom siv hluav taws xob tiv thaiv hluav taws xob, tiv thaiv kub kub tiv thaiv cov ntiv tes kub ntawm PCB pawg thawj coj, thiab xov tooj txawb lithium roj teeb tsim thiab ntim khoom. Lub Hom Phiaj: Tiv thaiv polyimide high temperature daim kab xev rwb thaiv tsev ua los ntawm Golden Finger Company. Nws yog ua los ntawm cov yeeb yaj kiab polyimide ua cov khoom siv hauv paus thiab txheej nrog kub kub tiv taus silica gel. Nws muaj qhov kub tsis kam tiv taus thiab siv rau kub reflow soldering. Kev tiv thaiv ntiv tes.
