PPLICATIONS 四端點量測技術可以用來準確地測量點2與點3之間的電阻。
Test and measuring equipment 測量電阻
電阻計是測量電阻的儀器。由於探針電阻和接觸電阻會造成電壓降,簡單電阻器不能準確地測量低電阻。高準確度測量工作必須使用四端點測量技術(
four-terminal measurement technology)。
Industrial and medical electronics
The MPM- Metal film Resistor are made by depositing special treated
metal film onto ceramic core in ultra high vacuum. Both ends
of the core are plated with precious metal to ensure low noise
and small temperature coefficient. MPM Resistor are widely applied in
high fidelity stereo, electronic calculators, computers, testing instruments,
meters, auto controlled equipment, military devices and aerospace equipment.

LED燈絲泡是怎樣鍊成的
產品應用 LED燈絲泡是怎樣鍊成的 SINLOON®
傳統LED燈珠光源及成品(圖一) LED燈絲及制成品 (圖二)
LED燈絲光源其制程工藝有別於LED燈珠光源,它採取一種全新的封裝技術,選用LED燈絲光源可以制作出
與昔日最傳統鎢絲燈泡的模樣,可以 發出360度光角度
LED燈絲封裝是一種最新的技術,普通的LED燈珠單顆電壓為3.0V的光源固定在塑料支架上的,再進行點膠
封裝,即PLCC封裝。而LED燈絲是將多個單顆光源串聯固定在雙面玻璃片上的,鋁基板或藍寶石基板上(圖二),
再進行模壓封裝完成。它有小電流高電壓的特性,可以有效的降低LED發熱溫度,大大降低了成本。而LED
燈絲它所採用的基板材質會直接影響到燈絲發出的光效。
