Lead Forming⏹ During lead formation, the leads should be bent at a point at least 3mm from the base of the epoxy bulb.⏹ Lead forming should be done before soldering.⏹ Avoid stressing the LED package during leads forming. The stress to the base may damage the LED’s characteristics or it may break the LEDs.⏹ Cut the LED lead frames at room temperature. Cutting the lead frames at high temperatures may cause failure of the LEDs. ⏹When mounting the LEDs onto a PCB, the PCB holes must be aligned exactly with the lead position of the LED. If the LEDs are mounted with stress at the leads, it causes deterioration of the epoxy resin and this will degrade the LEDs.2. Storage ⏹ The LEDs should be stored at 30°C or less and 70%RH or less after being shipped from Everlight and the storage life limitsare 3 months. If the LEDs are stored for 3 months or more, they can be stored for a year in a sealed container with a nitrogen atmosphere and moisture absorbent material. ⏹Please avoid rapid transitions in ambient temperature, especially, in high humidity environments where condensation can occur.3. Soldering ⏹ Careful attention should be paid during soldering. When soldering, leave more then 3mm from solder joint to epoxy bulb,and soldering beyond the base of the tie bar is recommended. ⏹Recommended soldering conditions:Hand SolderingDIP SolderingTemp. at tip of iron300℃ Max. (30W Max.) Preheat temp.100℃ Max. (60 sec Max.) Soldering time 3 sec Max. Bath temp. & time 260 Max., 5 sec Max Distance 3mm Min.(From solderjoint to epoxy bulb)Distance 3mm Min. (From solderjoint to epoxy bulb)⏹ Recommended soldering profile⏹ Avoiding applying any stress to the lead frame while the LEDs are at high temperature particularly when soldering. ⏹ Dip and hand soldering should not be done more than one time⏹ After soldering the LEDs, the epoxy bulb should be protected from mechanical shock or vibration until the LEDs return to room temperature.⏹A rapid-rate process is not recommended for cooling the LEDs down from the peak temperature.⏹Although the recommended soldering conditions are specified in the above table, dip or hand soldering at the lowestpossible temperature is desirable for the LEDs.⏹Wave soldering parameter must be set and maintain according to recommended temperature and dwell time in the solderwave.4. Cleaning⏹When necessary, cleaning should occur only with isopropyl alcohol at room temperature for a duration of no more thanone minute. Dry at room temperature before use.⏹Do not clean the LEDs by the ultrasonic. When it is absolutely necessary, the influence of ultrasonic cleaning on the LEDsdepends on factors such as ultrasonic power and the assembled condition. Ultrasonic cleaning shall be pre-qualified to ensure this will not cause damage to the LED5. Heat Management⏹Heat management of LEDs must be taken into consideration during the design stage of LED application. The currentshould be de-rated appropriately by referring to the de-rating curve found in each product specification.⏹The temperature surrounding the LED in the application should be controlled. Please refer to the data sheet de-ratingcurve.6. ESD (Electrostatic Discharge)⏹The products are sensitive to static electricity or surge voltage. ESD can damage a die and its reliability.When handling the products, the following measures against electrostatic discharge are stronglyrecommended:Eliminating the chargeGrounded wrist strap, ESD footwear, clothes, and floorsGrounded workstation equipment and toolsESD table/shelf mat made of conductive materials⏹Proper grounding is required for all devices, equipment, and machinery used in product assembly.Surge protection should be considered when designing of commercial products.⏹If tools or equipment contain insulating materials such as glass or plastic,the following measures against electrostatic discharge are strongly recommended:Dissipating static charge with conductive materialsPreventing charge generation with moistureNeutralizing the charge with ionizers7.

一、启动1、x-loader是一级引导程序,系统上电后由CPU内部firmware自动拷贝到内部RAM并执行。
主要作用为初始化CPU,拷贝u-boot到内存中,然后把控制权交给u-boot;2、u-boot是二级引导程序,主要用于和用户进行交互,提供映像更新、引导内核等功能;3、kernel使用最新2.6.32 内核,根据SOC8200进行定制;4、rootfs采用开源文件系统,体积小,功能强大。
温馨提示:J24 接上跳线帽后,上电启动的时候,系统将会优先从SD 卡启动。
更新NANDFLASH:更新NAND Flash 需要在u-boot 的命令行上对NAND操作,系统从SD卡启动后通过U-boot烧写NANDFLASH。
第1章Introduction1.1 疑问:1)OMAP35x OneDRAM技术具体是指?POP封装顾名思义, 是两个芯片叠在一起对于OMAP3的POP封装, OMAP3表面提供焊盘, mDDR贴在OMAP3的表面, Beagle 板子就是这样的, 这样的好处是省去了PCB面积和DDR的走线, 坏处是生产比较困难2)OMAP35x仅有6个GPIO,而AM3517有186个GPIO?解决:A maximum of 170 GPIO pins are supported. The following GPIO pins are not available: gpio_52, gpio_53, gpio_63 gpio_64, gpio_144, gpio_145, gpio_146, gpio_147, gpio_152, gpio_153, gpio_154, gpio_155, gpio_175, and gpio_176. Pin muxing restricts the total number of GPIO pins available at one time. See your device-specific data manual for more information on pin multiplexing.3)IV A2.2 subsystem (DSP) can’t access SoC peripherals。

Streamline your flow measurement operation with the FP-5300 Series flow sensor. Using this compact flow sensor, a matched sensor installation fitting, an OMEGA TM flow meter or controller, and ordinary handtools, you canassemble a complete flow monitoring or controlling system in minutes. Accurate to ±0.2 fps, with repeatability at ±0.1 fps, this insertion sensor operates on a simple electromechanical principle, proven in thousands of liquid flow applications worldwide. It all adds up to precision, dependability, and convenience– basic advantages that are quickly surpassing its in-line competition.A TIMESAVER YOU CAN BANK ONConvert your maintenance hours into minutes with the FP-5300. Should a sensor, rotor, or O-ring need to be replaced, it takes only seconds. Reduce your system downtime substantially with a stand-alone FP-5300 sensor, or simply add a Wet Tap Assembly and eliminate downtime completely. Combined with the FP-5300 during initial installation, the Wet Tap allows sensor removal without system shut-down. Optional local or remote capability lets you place your meter up to 200 feet away without signal amplification, and you can install the FP-5300 in pipe sizes ranging from 1⁄2 inch to 36 inches without a lot of additional cost, because the price of the FP-5300 increases only slightly for larger pipe sizes.RUGGED CONSTRUCTION FOR LONG WEAR Available in a choice of chemically resistant, non-contaminating housing materials, the FP-5300 stands up to the harshest environments. The glass-filled polypropylene housing version is lightweight but strong, which makes it ideal for handling a wide range of liquids, including corrosive fluids in chemical processing. For processes involving acids and solvents, the PVDF (polyvinylidene fluoride) housing version is a tough fluorocarbon that is highly resistant to more severe fluids.

Four permanent magnets, imbedded in the rotor blades, spin past a coil in the sensor body. As the fluid flow causes the rotor to move, a sine wave signal is produced, directly proportional to the flowrate. The patented “open cell” feature of the rotor ensures a linear, repeatable output, up to 23 fps, with accuracy of ±0.2 fps. The result is minimal head loss and no cavitation.3PRESSURE/TEMPERATURE CHARTSFor FP-5100, FP-5200, FP-5300 and FP-8500 Series Sensors and Associated FittingsNOTE: All pressure/temperature ratings listed are for water under non-shock conditions with no pressure cycling. Various chemicals and cycling pressures up and down can weaken plastics. Fittings must be installed so that the fitting does not carry the weight of the piping and does not suffer from thermal expansion stresses. Water hammer, fluid surges, and cavitation must always be avoided. If the end user elects to thread the plastic fittings with socket ends, the pressure rating will be substantially decreased.FP-5100, FP-5300 and FP-8500 Series SensorsPVC and CPVC Tees and SaddlesThese ratings are for PVC and PVDF fittings. For all metal fittings 10" and larger, a PVC insert is used; for 8" and below, a PVDF insert is used. Use the appropriate curve to determine the maximum pressure rating of these fittings.。
