Introduction to some electronic assembly tools.
Screwdriver
Screwdriver has "one" shape and "ten" shape, specially for fastening and disassembling screws. Screwdriver of different specifications can be selected according to the size of the screw when used. But when twisting, do not force too hard, so as not to screw slippage.
In addition, in the electrician training, there is also a non-inductive screwdriver, which is made from insulating materials such as plexiglass, Bakelite bars, stainless steel, wooden tribute or copper materials. Usually it can be used to adjust the intermediate frequency transformer and the middle cycle core in the oscillating coil, which can avoid the interference caused by human induction. White sensorless screwdriver should be based on the size of the core to determine the size of its size.
Tweezers
Tweezers are one of the most commonly used tools, including pointed tweezers and circular tweezers. Electronic components are usually small, assembly space is also relatively small, tweezers is the extension of the finger.The main function of tweezers is to hold wires and components to move during welding. In addition, using tweezers to hold components welding also plays the role of heat dissipation, such as in welding diodes and Triode, in order to protect the device from high temperature damage, welding can be used to clamp tweezers on the top of the pin to help heat dissipation.Mingda water choice 110-130mm 's stainless steel tip tweezers, such tweezers good elasticity and tip fit is good.
Cone
Silver in the main fee to paperboard Pu glue plank E Za and Chuan to penetrate the circuit board on the back of the final without the device,The shank cone is replaceable.
Brush and leather blowing
The brush is a tool for removing dirt fields from electrical equipment, deep dirt and welding residue on printed circuit boards. One way to say, can be equipped with a 10mm about the width of a brush, or with a brush or cultural brush can be replaced.
Skin blowing, also known as a leather tiger, is a tool that uses gas to remove dirt. Where brush can not be used, can be blown to clean up the dirt. Skin blowing is more effective for cleaning dust and other suspended dirt.
Steel file
There are many types of steel files that can be used to file flat holes in the housing burr on the cutting edge of the printed circuit board and to file the oxide on the electric iron head. The steel file is hard and brittle and easy to break, so the steel file is not allowed to be used as other tools such as crowbar taper. Use only one side of the first, use the full length of the steel file as far as possible, the surface after blunt and then use the other side, so as to prolong the service life of the steel file.
Hot melt glue gun
It is a special tool for heating and melting hot melt glue rods.In electronic training, the role of hot melt adhesive is to cement the housing, the printed circuit board in the shell, or the electronic components to the insulation board, using it to cement the object is more flexible and quick, and easy to disassemble. However, it should be noted that hot melt adhesive can not be used to bond heating components and strong vibration components.
Hot air guns
It is specially used for surface mounting electronic components (especially multi-pin SMD integrated circuit) welding and welding.
The heating element inside the hot melt glue gun is a PTC ceramic with a Curie point of not less than 280 degrees, with a fastening heat conduction structure. The hot melt glue rod is heated in the fertilizer and melted into the glue paste. The glue is extruded from the nozzle with the trigger of the hand plate. To facilitate the bonding of objects.
