M251296 創作說明(1) 【新型所屬之技術領域】 本創作係一種無引腳晶片承載座,尤指一種射出成型 之無引腳晶片承載座。 【先前技術】 隨著多媒體市場的蓬勃發展’影像感測晶片的應用範 圍亦愈來愈廣,諸如數位相機、電腦、手機、影像辨識裝 置等都應用到影像感測晶片’然而由於影像感測晶片需接 收外界光源以進行影像感測,故其封裝方式與一般晶片有 所不同,而目前業界常用的的影像感測晶片&裝技:包括 陶瓷無引腳晶片承載座(Ceramic Leadless ChipM251296 Creation Instructions (1) [Technical Field of New Type] This creation is a leadless wafer carrier, especially an injection-molded leadless wafer carrier. [Previous technology] With the rapid development of the multimedia market, the scope of application of image sensing chips is becoming wider and wider, such as digital cameras, computers, mobile phones, image recognition devices, etc. are applied to image sensing chips. However, due to image sensing The chip needs to receive an external light source for image sensing, so its packaging method is different from ordinary chips. At present, the image sensing chip commonly used in the industry & mounting technology: including ceramic leadless chip carrier (Ceramic Leadless Chip
Carrier,CLCC )技術及塑膠無引腳晶片承載座(piastic Leadless Chip Carrier,PLCC)技術,其中CLCC 技術如 美國專利公告號第589821號所示,其雖然氣密閉性良好, 能夠延長感測晶片之使用壽命,但由於製程繁瑣、且成本 較高,因而不符合一般市場需求。 而PLCC技術為目前多數業者所採用之封裝方式,其成本雖 較CLCC技術為低,但由於利用PCB板作為基底,故總體尺 寸難以縮小’日後將成為電子產品微型化的關鍵問題。另 外,PLCC之製造多採邊框與基底分別製造,然後再組設在 一起之方式,故在備料及生產的連貫性上有所影響,且 PLCC之製,係採單顆製程,亦即需先將邊框與基底所構成 之基座切單,接著再個別進行晶片黏著等動作,因此製造 速度較慢’製程不穩定因素亦較多。 有鑑於此’本創作針對上述習知技術之困擾,提出一Carrier (CLCC) technology and plastic leadless chip carrier (PLCC) technology. Among them, the CLCC technology is shown in US Patent Publication No. 589821. Although its air tightness is good, it can extend the length of the sensing chip. Service life, but because of the complicated process and high cost, it does not meet the general market requirements. And PLCC technology is the packaging method adopted by most of the industry. Although its cost is lower than CLCC technology, it is difficult to reduce the overall size due to the use of PCBs as a substrate. It will become a key issue for miniaturization of electronic products in the future. In addition, PLCC manufactures multiple frames and substrates separately, and then sets them together, so it affects the continuity of material preparation and production. Moreover, the PLCC system is a single process, which means that it needs to be manufactured first. The pedestal formed by the frame and the substrate is singulated, and then actions such as wafer adhesion are performed individually, so the manufacturing speed is slower, and there are also more process instability factors. In view of this, this creation addresses the problems of the above-mentioned conventional technologies, and proposes a
