自從人們從機(jī)械式鍵盤轉(zhuǎn)到現(xiàn)在的硅膠按鍵式鍵盤后,導(dǎo)電膜行業(yè)飛速發(fā)展,從原先的0.125MM,0.1,0.075MM厚的材料到現(xiàn)在的0.075,0.075,0.075MM厚的材料,可謂是價(jià)格每年都在走過(guò)山車式的下滑:近兩年一改傳統(tǒng)的導(dǎo)電銀漿材料,用導(dǎo)電碳漿印制鍵盤導(dǎo)電膜,更是大家想盡一切辦法降低成本,價(jià)格已經(jīng)降到了成本了,基本上已經(jīng)沒(méi)有什么可以再向前發(fā)展的方向了,期待新的材料能更低吧!

鍵盤導(dǎo)電膜開關(guān)層:
開關(guān)層一般在低于0.25MM的PET、PC等無(wú)色透光片材絲印上精美圖案和文字制作而成,因開關(guān)層最主要的作用在于起標(biāo)識(shí)和按鍵作用,所以選用材料必須具有高透明度、高油墨附著力、高彈性、防折性等特點(diǎn)。
