PACKAGE INSPECTION AND COMPONENT IDENTIFICATION  \nThe project kit comes in one package as shown in Fig.1. Unpack the bag and identify its content using parts list enclosed. Verify that parts are correct and free of damage, and that they correspond to parts list. Always keep unused parts in the very same bag with your name on it. Report immediately if you find that some parts are missing or that part numbers are wrong. Handle parts and boards with extreme care to minimize damage due to electrostatic discharge, mechanical abuse or dirt and sweat which causes oxidation of soldering surfaces.  \nFigure 1-1: Oscilloscope project 06204KP package bag  \nFigure 1-2: Oscilloscope project 06204KP package bag content  \nFigure 1-3: Identification of components layout and soldering points  \nVERIFY CORRECT PN NUMBER  \n\n| \u003Cbr>2. TOOLS\u003Cbr>In figures below you can recognize some but not necessarily all of the tools required for assembly of this oscilloscope kit. For the purpose of successfully soldering I recommend very sharp iron tip with at\u003Cbr>least two-three different diameters of soldering wires. All soldering illustrated in this instructions has been performed using a 40-watt soldering iron shown in figure (compared to a LED, size-wise) . Do not forget de-soldering wick, cleaning sponge and screwdrivers. Be careful when using de-soldering pump especially if it is as powerful as the one shown; multiple suction operations usually end up lifting the whole pad from the board. In many cases this means only one thing good bye project! When handling the PCB or components , use edges or non-soldering parts. Clean the components’ leads if you notice traces of corrosion on them: almost all components from a sample kit used for the purpose of this instructions, have required some cleaning to be done; I have used a long-nose\u003Cbr>pliers (see diode bending figure further down in text) to strip away dirt along the leads around soldering or cutting points.\u003Cbr>|  |\n| --- | --- |\n| Make sure your hand is not shaking while soldering by providing at least one fixing point of the arm. The tip approaching angle should be convenient for easy lead touch and safe solder flow. Do not apply soldering iron to thin soldering pads for longer than 5 sec! If you fail to finish soldering in first attempt, repeat again after cooling down the padsand solder for 5-10 sec.\u003Cbr>A solid board stand (holder) is crucial in having a steady and safe soldiering conditions. Magnifying glass is optional but very useful when checking the quality of your work and inspecting for solder bridges or metallic debris on PCB. | |\n| DO NOT ATTEMPT TO COMPLETE THE TASK WITHOUT PROPER SOLDERING IRON OR TOOLS-IT IS VERY LIKELY THAT YOU WILL DAMAGE THE DEVICE!\u003Cbr>There should be no improvisation of any kind! This is an example of an electronic device of a high PCB complexity with heavy trace density; it has some very thin and therefore brittle traces which are sensitive to mechanical or heat damage. As with any other kit assembly, there is no guarantee that device will work fine at the end, unless you follow the instructions thoroughly and apply yourself as a dedicated professional! If you don’t do that - you will fail, no question!\u003Cbr>|  |\n\n\n| \u003Cbr>3. THROUGH-HOLE COMPONENT SOLDERING\u003Cbr>It is recommended to start soldering TH component in the following order:\u003Cbr>3.1 Diode D3\u003Cbr>A diode is a polarized device with clear distinction between the positive terminal (anode) made of ptype material, and the negative terminal (cathode) made of n-type doped material. By now, you should be able to determine diode polarity easily, using a DMM with diode-checking feature. However, most of the diodes have a white (or black, or silver) strip imprinted on diode body to simplify cathode identification. The anode terminal must be mounted into the hole (pad) marked as white square. Simply follow the silkscreen graphics of the diode on the PCB. This diode has protective function in case the applied voltage from an AC a","cbCaioVCxzKldWKg","https://ap.wps.com/l/cbCaioVCxzKldWKg","pdf",3230409,23,"English","# Package Inspection and Component Identification\n## Tools\n# Through-Hole Component Soldering\n## Diode D3\n## Electrolytic Capacitors\n## Inductor L2","[{\"question\":\"What should be checked when unpacking the oscilloscope kit package?\",\"answer\":\"Verify that all parts match the enclosed parts list, are not damaged, and include no missing items or incorrect part numbers.
