福禄克187万用表维修手册（副本）主板关键测试点一、电源电路驱动波形：测试LT1307芯片第5脚（SW）上的波形。
如图所示：电源电路使用的是LT1307（DC/DC芯片）产生600KHz驱动波形，如果测不到这个波形，整个电源电路是不会工作的，LT1307此芯片损坏会导致无法产生600KHz波形。
二、主时钟驱动波形。
测试7.37MHz晶振两端波形，为7.3M正弦波，如果这个晶振损坏或者没有波形，则整机无法正常工作（此晶振是给FLUKE2000单片机芯片提供时钟信号）。
93C56（EEPROM芯片）供电电压来自钽电容的3V供电。
提示：以上所有测试点都是以电源负极为参考点测量的电压和波形。
三、显示驱动芯片时钟波形。
FLUKE1998是LCD液晶屏驱动芯片，此芯片旁边有一颗32.768KHz的实时时钟晶振，此晶振波形为32K正弦波。
此32.768KHz实时时钟晶振如果损坏，会导致显示不正常，（FLUKE1998）液晶屏驱动芯片本身损坏也会导致显示不正常。
四、（主控芯片）/液晶屏驱动芯片供电电压。
FLUKE1998是液晶屏驱动芯片。
FLUKE2000是主控芯片（MCU）。
FLUKE1998（液晶屏驱动芯片）的供电是（TPS77030）LDO芯片输出的3.3V经过管子转换为3.09V左右的供电提供给液晶屏驱动芯片供电。
FLUKE2000（主控芯片）的供电来自电源电路中的钽电容产生的3.11V提供给主控芯片供电。
测试点如果图所示：↓五、模拟芯片（FLUKE669918）供电和基准电压。
FLUKE669918（模拟芯片），此芯片内部集成了：A/D转换，真有效值（RMS）模块，功能测量都是这个芯片完成的。
FLUKE669918芯片的供电电压来自TPS77001（LDO）芯片输出的5V供电。
LMC6042双运算放大器的供电电压也来自TPS77001输出的5V 供电。
REF43G是电压基准芯片，该芯片的6脚输出2.5V基准电压提供给FLUKE669918芯片内部的A/D转换电路基准电压。

Assembly of SMD PackagesFor SHTxx and STSxx Sensirion Humidity and Temperature SensorsPrefaceThe open cavity SMD Packages of Sensirion humidity and temperature sensors are designed for high volume applications and therefore they are compatible with standard assembly and soldering processes.Nevertheless, a humidity sensor is not a normal electronic component and some care has to be taken in to ensure proper and reliable operation of the sensor. This document contains information on soldering process and handling of SHTxx and STSxx sensors in a production environment.1 Soldering InstructionsFor soldering, standard reflow soldering ovens may be used. The sensors are designed to withstand soldering profile according to IPC/JEDEC J-STD-020 with peak temperatures at 260°C during up to30sec for Pb-free assembly in IR/Convection reflow ovens (see Figure 1).Figure 1 Soldering profile according to JEDEC standard. T P ≤ 260°C and t P ≤ 30sec above 255°C for Pb-free assembly. T L < 220°C and t L < 150sec. Ramp-up rate <3°C and ramp-down rate < 6°C/sec for temperatures > T L. The use of “no clean” type 3 solder paste2 is recommended. An appropriate amount of solder paste shall be used, to result in a stand-off height (clearance between the package body and an y part of the substrate) of 50μm to 75μm. Please consult the appropriate sensor data sheet for device specific information on the metal land pattern and recommendations on solder paste printing stencils. Sandard pick & place equipment and vacuum nozzles for standard QFN packages may be used for assembly of SHTxx and STSxx sensors. No board wash shall be applied to SHTxx humidity sensors. Therefore, and as mentioned above, it is strongly recommended to use “no-clean” solder paste. For manual soldering conta ct time must be limited to 5 seconds at up to 350°C.Immediately after the exposure to high temperatures SHTxx humidity sensors may temporarily read a negative humidity offset (typ. -1 to -2 %RH after reflow soldering). This offset slowly disappears again by itself when the sensor is exposed to ambient conditions (typ. within 1-3 days). If RH testing is performed immediately after reflow soldering, this offset should be considered when definingthe test limits. It is important to note that the diced edge or side faces of the I/O pads may oxidise over time, therefore a solder fillet may or may not form. Hence there is no guarantee for solder joint fillet heights of any kind.2 Storage Conditions and HandlingInstructionsIt is of great importance to understand that a SHTxx humidity sensor is not a standard electronic component and needs to be handled with care. Chemical vapors at high concentration in combination with long exposure times may offset the sensor reading. In manufacturing, transport and operation the sensors shall be prevented of high concentration of chemical solvents and long exposure times. Out-gassing of glues, adhesive tapes and stickers or out-gassing packaging material such as bubble foils, foams, etc. shall be avoided. Manufacturing area shall be well ventilated. For more detailed information please consult the document “Handling Instructions” or contact Sensirion.2 Solder types are related to the solder particle size in the paste: Type3 covers the size range of 25 – 45 µm as specified in IPC J-STD-005A .

关于芯片的复位
海尔 MCU 芯片具有内部上电复位。对于不同的快速上/下电或慢速上/下电系统，内部上电复位电路可能失效，建议 用户使用外部复位、下电复位、看门狗复位等，确保复位电路正常工作。在系统设计时，若使用外部复位电路，建 议采用三极管复位电路、RC 复位电路。若不使用外部复位电路，建议采用复位管脚接电阻到电源，或采取必要的 电源抖动处理电路或其它保护电路。具体可参照芯片的数据手册说明。
关于芯片的 ESD 防护措施
海尔 MCU 芯片具有满足工业级 ESD 标准保护电路。建议用户根据芯片存储/应用的环境采取适当静电防护措施。应 注意应用环境的湿度；建议避免使用容易产生静电的绝缘体；存放和运输应在抗静电容器、抗静电屏蔽袋或导电材 料容器中；包括工作台在内的所有测试和测量工具必须保证接地；操作者应该佩戴静电消除手腕环手套，不能用手 直接接触芯片等。
关于芯片的初始化
海尔 MCU 芯片具有各种内部和外部复位。对于不同的应用系统，有必要对芯片寄存器、内存、功能模块等进行初 始化，尤其是 I/O 管脚复用功能进行初始化，避免由于芯片上电以后，I/O 管脚状态的不确定情况发生。
关于芯片的管脚
海尔 MCU 芯片具有宽范围的输入管脚电平，建议用户输入高电平应在 VIHMIN 之上，低电平应在 VILMAX 之下。避免 输入电压介于 VIHMIN 和 VILMAX 之间，以免波动噪声进入芯片。对于未使用的输入管脚，应通过电阻上拉至电源电平 或下拉至地。对于未使用的管脚，建议用户设为输出状态，并通过电阻接至电源或地。对未使用的管脚处理因应用 系统而异，具体遵循应用系统的相关规定和说明。

海尔 MCU 芯片使用注意事项
关于芯片的上/下电 海尔 MCU 芯片具有独立电源管脚。当 MCU 芯片应用在多电源供电系统时，应先对 MCU 芯片上电，再对系统其 它部件上电；反之，下电时，先对系统其它部件下电，再对 MCU 芯片下电。若操作顺序相反则可能导致芯片内部
元件过压或过流，从而导致芯片故障或元件退化。具体可参照芯片的数据手册说明。
关于芯片的时钟
海尔 MCU 芯片具有内部和外部时钟源。内部时钟源会随着温度、电压变化而偏移，可能会影响时钟源精度；外部 时钟源采用陶瓷、晶体振荡器电路时，建议使能起振延时；使用 RC 振荡电路时，需考虑电容、电阻匹配；采用外 部有源晶振或时钟输入时，需考虑输入高/低电平电压。具体可参照芯片的数据手册说明。
