玻璃板上芯片封装关键装备研制与工艺开发
技术分类: |
2009-02-18 通过计算机控制系统、伺服驱动系统、图像处理系统、温度控制系统和压力控制系统等实现高稳定性和准确度工艺要求下的ACF、IC芯片和玻璃基板的粘贴动作的形成和协调等问题。
关键装备的研制开发
ACF贴附机的作用是提供一个平台,使各向异性导电膜ACF贴附到玻璃显示屏基板上。ACF是以最大直径为150 mm的卷状***在贴附机上,卷宽为1~6 mm。玻璃基板的尺寸为20 mm×15 mm~80 mm×80 mm,厚度0.3~1.1 mm。
ACF 在驱动装置的作用下,完成供给、剪切和剥离等动作。供给由电机提供动力,剪切剥离由气缸提供动力。在支持平台上,热压头由气缸驱动垂直运动,实现ACF和玻璃基板的贴附。在上述贴附过程中,热压头的温度通过PID等方式精密恒温控制。温度约为200℃,可以1℃为单位精确设定。同时热压头的压力也可精确控制和调整。特别重要的是热压头和支持平台的压合位置精度,例如平面度必须保持在±6μm以内。ACF贴附机的原型机如图2所示。
ACF贴附机开发的关键技术在于:精密机械动作的协调与控制、高精度的温度和压力控制。预压机(见图3)的作用是使IC芯片与贴附了ACF的玻璃显示屏基板预贴附成一体。IC芯片的尺寸为:3 mm×1 mm~30 mm×5 mm,厚度为0.3~0.7 mm。
IC芯片装在磁盘平台上,在x和y方向通过步进电机驱动。支持平台支承着玻璃基板。对位平台在x,y和θ方向可精密微调,以便调节IC芯片和玻璃基板之间的位置。采用CCD、LED光源、镜头等硬件和软件组成的图像识别和控制系统确保定位精度小于±3μm。
在完成芯片的精密定位后,热压头垂直移动,完成芯片的预压合动作。压力范围为9.8~98.0 N可调。特别重要的是要确保压合过程芯片所保持的定位精度,即压合过程无任何滑移。
通过预压将IC芯片邦定在LCD
上,使IC与LCD玻璃板之间的线路连通。IC芯片面积小,但I/O端数量多。要使IC与LCD玻璃板之间的线路很好的连通,就需要对IC和LCD进行非常精确的定位,保证足够的定位精度。
预压机开发的关键在于:微米级的高定位精度、图像处理的速度与精度、微量运动的调节和补偿。
本压机是最后完成芯片与玻璃基板贴合生产出合格的液晶显示屏模块的设备。本压机和液晶显示屏模块分别如图4、5所示。
本压机的压合温度高于预压机为400℃,可以1℃为单位精密调节,PID恒温控制。压力范围为17.2~294.0 N,可精确调整。热压头可在垂直方向精确控制并移动,驱动方式为气缸提供动力。热压头与支持平面的平面度要求高,应保持在±2μm内。支持平台支承玻璃基板,度高也可精密调节。
本压机开发的关键在于:运动精度、温度的稳定性和压力的精确性控制。
自动COG封装机是.ACF贴附、预压、本压一体化高效COG封装设备,同时装备有图像检测定位系统和三坐标程控调节功能,有两个压头,适用于多
。可广泛应用于177.8 mm以下STN、CSTN、TFT液晶模组批量生产。 综上所述,COG工艺过程所用的ACF贴附机、预压机和本压机可以使芯片贴焊到玻璃板上,线距10~30μm,最小连接面积1 600μm2,粘着力强度可靠。因此研究内容包括:
(1)开展ACF贴附、预压和本压原型机的实验分析;
(2)开展多工艺过程模型、多参数耦合模型、键合机理和模型、电气互联性能模型、机械互联强度模型等关键技术的分析与仿真;
(3)各部分机械结构的设计、性能分析与优化;
(4)计算机图像识别的定位系统开发、定位精度控制技术、定位准确性和稳定性问题;
(5)研究与温度控制相关的参数变化规律及其优化方法,开发PID恒温控制系统;
(6)研究与压力控制相关的工艺影响因素及其控制方法;
(7)开展运动、温度、压力等多参数与COG质量变化规律及协同控制方法的实验;
(8)分析和研究精密驱动电机与气动元件在COG工艺中应用的性能匹配和优化问题;
(9)研究关键零件制造工艺、热处理和表面处理工艺;
(10)其他相关工艺的研究,如热压头、支持平台采用特殊的工艺和材料的相关研究,以确保尺寸稳定。

ATmega8515、ATmega8515L单片机概述:
***R 内核具有丰富的指令集和32 个通用工作寄存器。所有的寄存器都直接与算逻单元(ALU) 相连接,使得一条指令可以在一个时钟周期内同时访问两个独立的寄存器。这种结构大大提高了代码效率,并且具有比普通的CISC 微控制器最高至10 倍的数据吞吐率。
ATmega8515 有如下特点:8K 字节的系统内可编程Flash( 具有同时读写的能力,即RWW),512 字节EEPROM,512 字节SRAM,一个外部存储器接口,35 个通用I/O 口线,
32 个通用工作寄存器,两个具有比较模式的灵活的定时器/ 计数器(T/C), 片内/ 外中断,可编程串行USART,具有片内振荡器的可编程看门狗定时器,一个SPI 串行端口,以及三个可以通过软件进行选择的省电模式。工作于空闲模式时CPU 停止工作,而SRAM、T/C、SPI 端口以及中断系统继续工作;掉电模式时晶体振荡器停止振荡,所有功能除了中断和硬件复位之外都停止工作; Standby 模式下只有晶体或谐振振荡器运行,其余功能模块处于休眠状态,使得器件只消耗极少的电流,同时具有快速启动能力。
本芯片是以Atmel 高密度非易失性存储器技术生产的。片内ISP Flash 允许程序存储器通过ISP 串行接口,或者通用编程器进行编程,也可以通过运行于***R 内核之中的引导序进行编程。引导程序可以使用任意接口将应用程序下载到应用Flash存储区(A licationFlash Memory)。在更新应用Flash存储区时引导Flash区(Boot Flash Memory)的程序继续运行,实现了RWW 操作。 通过将8 位RISC CPU 与系统内可编程的Flash 集成在一个芯片内, ATmega8515 成为一个功能强大的单片机,为许多嵌入式控制应用提供了灵活而低成本的解决方案。
ATmega8515 具有一整套的编程与系统开发工具,包括:C 语言编译器、宏汇编、 程序调试器/ 软件仿真器、仿真器及评估板。

LPC2148FBD64单片机解密是近期成功突破的疑难解密单片机型号之一,LPC系列单片机由于其本身较为复杂,加密性能较好,业界对该系列单片机解密的技术研究还不成熟,因此,该系列单片机解密难度较大,解密费用相对较高。对LPC2148FBD64单片机解密的成功突破将为更多客户在学习、研究等过程中提供更可靠的技术支持。
这里,我们将对LPC2148FBD64单片机做一个详细的说明,供客户及专业技术工程师参考:
关于LPC2148FBD64系列单片机:
The LPC2148 microcontrollers are based on a 16-bit/32-bit ARM7TDMI-S CPU with real-time emulation and embedded trace su ort, that combine microcontroller with embedded high- eed flash memory ranging from 32 kB to 512 kB. A 128-bit wide memory interface and a unique accelerator architecture enable 32-bit code execution at the maximum clock rate. For critical code size a licatio , the alternative 16-bit Thumb mode reduces code by more than 30 % with minimal performance penalty.
Due to their tiny size and low power co umption, LPC2148 are ideal for a licatio where miniaturization is a key requirement, such as acce control and point-of-sale. Serial communicatio interfaces ranging from a USB 2.0 Full- eed device, multiple UARTs, SPI, SSP to I2C-bus and on-chip SRAM of 8 kB up to 40 kB, make these devices very well suited for communication gateways and protocol converters, soft modems, voice recognition and low end imaging, providing both large buffer size and high proce ing power. Various 32-bit timers, single or dual 10-bit ADC(s), 10-bit DAC, PWM cha els and 45 fast GPIO lines with up to nine edge or level se itive external interrupt pi make these microcontroller suitable for industrial control and medical systems.

ATMEL89系列单片机是以8031核心构成的,所以,它和8051系列单片机是兼容的系列。这个系列对于以8051为基础的系统来说,是十分容易进行取代和构造的。故而对于熟悉8051的用户来说,用ATMEL公司的89系列单片机进行取代8051的系统设计是轻而易举的事。
咨询QQ:1730808445 Email:xi ian007@163.com
一、89系列单片机的优点
89系列单片机对一般用户来说,有以下明显的优点:
1.内部含Flash存储器
因此在系统的开发过程中可以十分容易进行程序的修改,这就大大缩短了系统的开发周期。同时,在系统工作过程中,能有效地保存一些数据信息,即使外界电源损坏也不影响到信息的保存。
2.和80C51插座兼容
89系列单片机的引脚是和80C51一样的,所以,当用89系列单片机取代80C51时,可以直接进行代换。这时,不管采用40引脚亦或44引脚的产品,只要用相同引脚的89系列单片机取代80C51的单片机即可。
3.静态时钟方式
89系列单片机采用静态时钟方式,所以可以节省电能,这对于降低便携式产品的功耗十分有用。
4.错误编程亦无废品产生
一般的OTP产品,一旦错误编程就成了废品。而89系列单片机内部采用了Flash存储器,所以,错误编程之后仍可以重新编程,直到正确为止,故不存在废品。
5.可进行反复系统试验
用89系列单片机设计的系统,可以反复进行系统试验;每次试验可以编入不同的程序,这样可以保证用户的系统设计达到最优。而且随用户的需要和发展,还可以进行修改,使系统不断能追随用户的最新要求。
二、89系列单片机内部结构
89系列单片机的内部结构和80C51相近,它主要含有如下一些部件。
1. 8031CPU
2. 振荡电路
3. 总线控制部件
4. 中断控制部件
5. 片内Flash存储器
6. 片内RAM
7. 并行I/O接口
8. 定时器
9. 串行I/O接口
在89系列单片机中,AT89C1051的Flash存储器容量最小,只有1K;而AT89C52,AT89LV52,AT89S8252的Flash存储器容量最大,有8K.这个系列中,结构最简单的是AT89C1051,它内部也不含串行接口;最复杂的是AT89S8252它内部不但含标准的串行接口,还含一个串行外围接口SPI,Watchdog定时器,双数据指针,电源下降的中断恢复等功能和部件。

Simple DMA
In a simple DMA case, a single TD tra fers data between a
source and sink (peripherals or memory location)。
4.4.4.2 Auto Repeat DMA
Auto repeat DMA is typically used when a static pattern is repetitively
read from system memory and written to a peripheral. This
is done with a single TD that chai to itself.
4.4.4.3 Ping Pong DMA
A ping pong DMA case uses double buffering to allow one buffer
to be filled by one client while another client is co uming the
data previously received in the other buffer. In its simplest form,
this is done by chaining two TDs together so that each TD calls
the o osite TD when complete.
4.4.4.4 Circular DMA
Circular DMA is similar to ping pong DMA except it contai more
than two buffers. In this case there are multiple TD after the last
TD is complete it chai back to the first TD.
4.4.4.5 Scatter Gather DMA
In the case of scatter gather DMA, there are multiple noncontiguous
sources or destinatio that are required to effectively
carry out an overall DMA tra action. For example, a packet may
need to be tra mitted off of the device and the packet elements,
including the header, payload, and trailer, exist in various
noncontiguous locatio in memory. Scatter gather DMA allows
the segments to be concatenated together by using multiple TDs
in a chain. The chain gathers the data from the multiple locatio .
A similar concept a lies for the reception of data onto the
device. Certain parts of the received data may need to be
scattered to various locatio in memory for software proce ing
convenience. Each TD in the chain ecifies the location for
each discrete element in the chain.
4.4.4.6 Packet Queuing DMA
Packet queuing DMA is similar to scatter gather DMA but ecifically
refers to packet protocols. With these protocols, there may
be separate configuration, data, and status phases a ociated
with sending or receiving a packet.
For i tance, to tra mit a packet, a memory ma ed configuration
register can be written i ide a peripheral, ecifying the
overall length of the e uing data phase. The CPU can set up
this configuration information anywhere in system memory and
copy it with a simple TD to the peripheral. After the configuration
phase, a data phase TD (or a series of data phase TDs) can
begin (potentially using scatter gather)。 When the data phase
TD(s) finish, a status phase TD can be invoked that reads some
memory ma ed status information from the peripheral and
copies it to a location in system memory ecified by the CPU
for later i ection. Multiple sets of configuration, data, and
status phase “subchai ” can be strung together to create larger
chai that tra mit multiple packets in this way. A similar
concept exists in the o osite direction to receive the packets.
