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。

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 .

The good input capacitor will limit theinfluence of input trace inductances and source resistanceduring sudden load current changes.Higher capacitance and lower ESR capacitors willimprove the overall line transient response.Output Decoupling (C OUT )The NCP718 does not require a minimum Equivalent Series Resistance (ESR) for the output capacitor. The device is designed to be stable with standard ceramics capacitors with values of 1 m F or greater. The X5R and X7R types havethe lowest capacitance variations over temperature thus theyare recommended.The maximum power dissipation the NCP718 can handle is given by:P D(MAX)+ƪT J(MAX)*T A ƫR q JA (eq. 1)The power dissipated by the NCP718 for given application conditions can be calculated from the following equations:P D [V IN ǒI GND (I OUT )Ǔ)I OUT ǒV IN *V OUT Ǔ(eq. 2)orV IN(MAX)[P D(MAX))ǒV OUT I OUT ǓI OUT )I GND (eq. 3)Hints V IN and GND printed circuit board traces should be aswide as possible. When the impedance of these traces ishigh, there is a chance to pick up noise or cause the regulatorto malfunction. Place external components, especially theoutput capacitor, as close as possible to the NCP718, andmake traces as short as possible .ORDERING INFORMATION Device Part No.Voltage Option Marking Option Package Shipping †NCP718AMTADJTBGAdj.GA With Active Output Discharge WDFN6(Pb−Free)3000 / Tape & ReelNCP718BMTADJTBGAdj.GC Without Active Output Discharge NCP718ASNADJT1GAdj.GAA With Active Output Discharge TSOT−23−5(Pb−Free)3000 / Tape & Reel NCP718ASN120T1G1.2 V GAE NCP718ASN150T1G1.5 V GAF NCP718ASN180T1G1.8 V GAD NCP718ASN250T1G2.5 V GAG NCP718ASN300T1G3.0 V GAH NCP718ASN330T1G3.3 V GAJ NCP718ASN500T1G5.0 V GAK NCP718BSNADJT1GAdj.GAC Without Active Output Discharge NCP718BSN180T1G1.8 V GCD NCP718BSN500T1G 5.0 V GCE †For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specifications Brochure, BRD8011/D.TOP VIEW SIDE VIEWEND VIEWNotes:(1) All dimensions are in millimeters.

The board contains connectors for easy development with a PC using the main host connections, USB and UART through a USB converter. Also present are headers for all the GPIO pads connected around a prototyping area for easy connection of pin headers with custom pinouts, sensors etc.The WF121 is a self-contained Wi-Fi module providing a fully integrated 2.4GHz 802.11 b/g/n radio and a 32-bit microcontroller (MCU) platform, making it an ideal product for embedded applications requiring simple, low-cost and low-power wireless TCP/IP connectivity. WF121 also provides flexible interfaces for connecting to various peripherals. WF121 allows end user applications to be embedded onto the on-board 32-bit microcontroller using a simple Bluegiga BGScript TM scripting language. This cuts out the need of an external MCU and allows the development of smaller and lower-cost products. However WF121 can also be used in modem-like mode in applications where the external MCU is needed.With an integrated 802.11 radio, antenna, single power supply, and regulatory certifications, WF121 provides a low-risk and fast time-to-market for applications requiring Wi-Fi connectivity. This co mbined with Bluegiga’s excellent customer service will turn your Internet-of-Things applications into reality. KEY FEATURES:-USB or UART host connection-USB converter for the UART-Can be powered through USB-Current measurement voltage output -Prototyping areaPHYSICAL OUTLOOK:2 Ordering InformationConfidentialConfidential 3Board Description3.1 WiFi ModuleDKWF121 contains a WF121-A module variant, with an internal chip antenna.3.2 CrystalsThere are two crystals assembled on DKWF121, an 8MHz crystal for the WF121 CPU clocking and a32.768kHz crystal for the CPU real time clock. The 8MHz crystal is needed when the WF121 USB connection is used, otherwise it is not essential. The 32kHz crystal is also optional, and if extra GPIO are needed, the 0ohm resistors connecting the crystals to the module can be removed and moved to connect the pin headers and prototyping area pads to the module pads. The pads are not connected to the pin headers by default as crystal connections are always sensitive to noise.3.3Configurable I/O PortsAll the GPIO pads available on the WF121 are routed to pin headers for easy connection to other boards or a logic analyzer. All the signals are also available on through-hole pads on the edges of the board prototyping area for easy development prototyping.The GPIO signals associated with the crystals are routed but not connected due to the presence of the crystals, but if required the crystals can be removed and the associated 0ohm resistors moved to connect the signals to the headers.The signals shared for other functions like the ICSP programming interfac e, JTAG, UART’s and Ethernet should not be driven by externally connected outputs when the mentioned functions are used to avoid damage. The UART and Ethernet signals are disconnected when the associated on-board chips are disabled with the on-board switches.The USB pins are by default disconnected from the pin headers, but can be connected by adding two jumpers to the specific header.3.4 Bluetooth CoexistenceIndustry standard 2-wire and 3-wire, as well as Unity-3, Unity-4, Unity-3e coexistence schemes are supported as well as the Unity+ -extension, and the associated signals are available. The PIO pads can be configured for these functions among others. A U.FL connector is also present for antenna sharing using the module internal RF switch. As only 4 GPIO signals can be used for coexistence, antenna sharing in practice requires the use of the CSR proprietary Unity-3e or 3e+ scheme.3.5 LEDs and ButtonsThere are five LEDs and five pushbuttons on the DKWF121. One button is for module reset and one LED indicates that the module has a power supply present, while the other four LEDs and buttons are available for development purposes. The LEDs are buffered with MOSFETs and the buttons are open when unpressed, allowing the connected GPIO lines to be used for other purposes without disconnecting the LEDs or buttons.Confidential3.6USB Connectionsoperating systems with either inbuilt or automatically installed drivers.ConfidentialConfidential No separate connectors for SPI host connections are provided as there is no standard connector or pinout, but the signals are available on the pin headers and pads on the prototyping area edge for easy soldering of a connector with a custom pinout.3.7Board PowerDKWF121 can be powered by several sources.∙ Both USB connectors can be used as the power supply input ∙ A two-pin header∙The signal pin headers and prototyping area connections have power connectionsNote: if the on-board WF121 module does not contain firmware that operates the native USB connection, the module cannot request an increase to the USB default current limit of 100mA. Although not all USB host systems implement it, the USB specification states that the host should limit the current output to 100mA unless an increase is requested, and using the module with high transmit duty cycles may cause the USB host to go into current limit, possibly causing the module to crash. It is preferred to power the board through the USB/UART-converter connector, the converter chip will automatically request for an increased current limit. The board contains a switch mode converter that converts the 5V input to the 3.3V supply required by the module. The converter is specified for output currents up to 600mA, allowing up to 200mA to be drawn for powering customer applications.The module operates down to 2.7V, but the current measure output and USB host functionality require a regulated 5V input. The header and the USB connectors also have series schottky diodes, increasing the minimum input voltage slightly. The 5V power connections in the prototyping area and the associated pin headers do not have series diodes. The diodes allow connection of a USB host together with a separate power supply without risk of damage.3.8 Current Measurement Point J13Header J13 contains a jumper that connects the switch mode regulator to the module 3.3V supply pads. The jumper can be removed and the average current consumption of the module can be measured with a multimeter or a series resistor can be inserted for measuring the momentary current consumption of the module with an oscilloscope. Note that for average consumption measurement of anything else besides sleep current a fast RMS multimeter is needed due to the pulsed nature of the consumption.Removing the jumper also allows separation of the module supply lines from the regulator output, for example when using an external regulator to supply the 3.3V voltage to the module is desired.3.9 VDD_PA Selection Header J7WF121 has two power supply inputs, VDD_3.3V (VDD_3.3V_MOD line on the schematic) and VDD_PA. The VDD_3.3V pad supplies the internal processor and has a voltage range of 2.3V to 3.6V. The VDD_PA pad supplies the internal WiFi-circuitry through a switch mode converter and the WiFi power amplifier directly. TheVDD_PA line can operate with input voltages between 2.7V and 5.5V, though the power consumption of the power amplifier will grow in direct proportion to the input voltage. The separate supply however allows direct connection to a lithium-ion battery, with just a small linear regulator limiting the supply voltage for the processor side.A jumper at header J7 usually connects VDD_PA to the board 3.3V switch mode converter output. The jumper can be moved to the alternate position to supply the VDD_PA line directly from the 5V supply rail, for example for connecting directly to a lithium battery either through the power input header or through the prototyping area connections.3.10EthernetThe board contains a 10/100Mbps Ethernet PHY with all the associated components, connected to the module internal Ethernet MAC with an RMII interface. The PHY can be fully powered off and disconnected from the GPIO lines using switch SW1, allowing the GPIO lines to be used for other functions. The Ethernet interface is not yet supported by the Bluegiga software.3.11Programming ConnectionsDKWF121 contains two connectors that allow direct programming of the WF121 internal processor. The Microchip proprietary ICSP bus allows programming the full firmware image using a Microchip or third party programming adapter. The pin header installed on the DKWF121 has a pinout suitable for use with the low-Confidentialcost PicKit3 programming tool from Microchip. A JTAG connection is also available for basic boundary scans and device programming. The JTAG does not support full device testing and debugging.The primary means of uploading application data is through a host connection through the Bluegiga boot loader. The programming connections should not be needed unless the internal boot loader is overwritten by the application.3.12 Debug SPI InterfaceA header is provided for the module debug bus for certification RF testing. Access to internal settings and test modes is available using a CSR compatible SPI adapter and UniTest-software.For more information contact Bluegiga technical support.3.13 Prototyping AreaDKWF121 contains an array of through plated holes with wide pads with a 2.54mm raster for easy addition of carrier boards, through-hole components and pin headers with a custom pinout. Also present is a smaller array of pads with no holes using 1.27m raster for connecting SMD components like sensors, regulators etc during system development.All GPIO signals are routed to the prototyping area edges, though some of them are not by default connected due to function multiplexing. See other chapters for detailed descriptions of these signals.Also present on the pin headers and pads around the prototyping area are several supply voltage rails present on the board. These can be used for powering external circuitry, or for powering the module with external power sources. The uppermost and lowest rows of pads are connected to ground.Confidential4 Board layoutConfidential5 Contact InformationSales:******************Technical support:********************Orders: *******************WWW: www.bluegiga.hkHead Office / Finland:Phone: +358-9-4355 060Fax: +358-9-4355 0660Sinikalliontie 5A02630 ESPOOFINLANDPostal address / Finland:P.O.
