產(chǎn)品簡介 ?
我司長期生產(chǎn)銷售貼片式開關(guān)二極管CD4148系列,
片式二極管(厚膜封裝CD4148)
1>．拋料率低:革命性的封裝形式,適用于高速貼片,使用貼片式CD4148二極管不會(huì)有拋料問題,現(xiàn)各廠商普遍使用之產(chǎn)品為圓柱的Mini MELF,拋料率達(dá)到20%以上,貼片式CD4148二極管之拋料率都在0.2%以下,相差達(dá)到100倍,為各廠商節(jié)省大量的重工時(shí)間及費(fèi)用.
2>．信賴性高:由于芯片焊接方式的差異,產(chǎn)生不同的信賴性差異,MELF產(chǎn)品為點(diǎn)接觸(point contact),沒有焊接,當(dāng)二極管產(chǎn)生熱時(shí),將造成訊號斷續(xù)現(xiàn)象,貼片式CD4148二極管使用銀膏焊接,接觸點(diǎn)很完整,因此不會(huì)有此現(xiàn)象發(fā)生.
3>．厚度很薄:現(xiàn)在科技產(chǎn)品都追求輕薄短小,貼片式CD4148二極管是跨時(shí)代的產(chǎn)品,其厚度只有Mini MELF的一半,在手機(jī)、數(shù)碼像機(jī)、PDA、玩具、電子表等要求小型化的產(chǎn)品,提供一項(xiàng)極佳的選擇.貼片式CD4148二極管1206的尺寸和Mini MELF相差不多(厚度除外),在PC板Layout上完全兼容,不需更改圖面,0805和Micro MELF則有些不同,銅箔需加大一點(diǎn).而其尺寸大小和貼片電阻、貼片電容完全相同,PC板設(shè)計(jì)上更美觀,在自動(dòng)化插件機(jī)的使用上更可同時(shí)使用同一部機(jī)器操作,更為方便.
◆特點(diǎn)Features:
1>．符合ROHS指令要求;等同于1N4148電子特性;
2>．最先進(jìn)的大批量生產(chǎn)方式,可大幅度降低采購成本;
3>．FHD4148 1206 可直接代替LL-34;
4>．適應(yīng)再流焊與波峰焊;
5>．端頭強(qiáng)度可達(dá)到GB/T4937-1995 2mm標(biāo)準(zhǔn),徹底杜絕了之前同類產(chǎn)品抗彎強(qiáng)度差的問題;
優(yōu)勢:扁平塑料封裝貼片二極管CD4148,產(chǎn)品設(shè)計(jì)新穎超薄,焊接方便快捷,拋料率低,提高生產(chǎn)效率,降低成本,環(huán)保無鉛,具SGS報(bào)告,符合ROHS標(biāo)準(zhǔn),是追求高效益廠家的最好選擇.
貼片開關(guān)二極管 CD4148為什么客戶難接受呢?

為什么呢樓主
厚膜工藝源自數(shù)十年前日本羅姆公司所開發(fā)的平板片式電阻,工藝至今非常成熟,如今將碳晶棒改為各種二極管芯,例如較常見的有:(4148/zener /schottky/整流....)封裝而成, 以陶瓷片為基材散熱佳,塗覆上環(huán)氧樹脂可以通過SGS,與無鉛高溫回流焊錫 260度C 10秒,常見的平板式貼片二極管封裝方式有1206/0805/0603 可以直接替代LL-34 MELF SOD-123 SOD-323使用,不需更改電路板,採用日本羅姆公司專用4148芯片封裝,500MA 可以耐1-3小時(shí), 750MA 可以耐5-15分鐘 1500MA耐1.0秒 3000-4000MA耐8.3MS 性價(jià)比是已知各種封裝平板式貼片器件中最佳需要樣品聯(lián)繫MSN:gamachen2001@hotmail.com
