Steps to repair pet panel5

The steps for repairing the pet panel are as follows: 1. First remove the membrane switch panel. Open the top layer and press the film. Use a multimeter to find the connection position of each switch point and PCB to ensure that the modified switch connection point corresponds to the original T. 2. At each switch point of the substrate, the positioning cone is used to conify the holes on the metal plate. According to the actual scale of the tower, the size of the perforation scale is slightly larger than the size of the Mark switch. In order to ensure that the switch of the switch is not hindered by the movement of the inner and outer columns of the hole, if the hole is too small, it will play an elastic role of the switch and make the switch fail. 3. Compare the distance between each hole in the Golden Moon board. Fix the logo switch on the printing board and connect the connection points according to the corresponding connection points of each switch. According to the actual spatial position between the metal plate and the display Plate 2, the corresponding plate edge is omitted to fix the switch plate. Since the switch of the new plate is placed between the metal plate and the indicator plate. It is necessary to appear on the printed board and display 2 corresponding holes of the board lamp. In order to ensure that the display panel sees the signal display from the panel through the printed circuit board. In the case of a short circuit plate, the line is combined with the distance between the two. 4. Printed switch plates embedded in each ship. According to the switch and metal plate corresponding to the hole at the top of the column. According to health and gold surface. If the parallel fart surface is too high, the outer plate membrane cannot be used after the switch is pressed. If it is too low. Who can't work when pressing the switch by hand. The switch plate 'breaks the rubber pad after the block, then leaves, and the dry glue is pasted on the metal plate and the outer plate. After the protective film is restored. After the modified process completes the transformation of the J switch board, the operating handle is very good. When the key has a clear effect on the sound of the shrapnel. A very intuitive switch. Long service life, high reliability and convenient protection. If the switch is captured in use, it can be directly judged by the sound of the movie switch button. The materials used in pet panel film switch flexible circuits are insulating films, adhesives and conductors. The insulating film forms the bottom layer of the circuit, and the adhesive connects the copper foil to the insulating layer. In a multi-layer design, it is combined with the inner layer. They are also used as protective covers to separate the circuit from dust and humidity and reduce stress during bending. The copper foil forms a conductive layer. Film switch (Flexible circuit) The data of is composed of some rigid components made of aluminum or stainless steel. They can provide dimensional fluctuations and provide physical support and stress relief for the installation of components and conductors. The rigid element and the flexible circuit are bonded together. Another kind of data is sometimes used in flexible circuits. It is an adhesive layer. It is made of adhesive on the first two layers of insulating film. The connection layer provides protection and electronic insulation functions, and can eliminate a thin film and the ability to have a layer with fewer layers. There are many kinds of data for pet panel insulation film, but the most commonly used data are polyimide and polyester.
