What is a chip capacitor?
capacitors are electronic devices for storing charges and signal filtering that block direct current, but allow the alternating current to pass within the design parameters. Each capacitor includes two wires with an insulating, polarizable dielectric layer inserted between them. The chip capacitor is a generally rectangular device that is a capacitor of the selection for high -frequency electronic circuits. Its size is usually less than a quarter of the inch (6.35 mm) and works on a fraction of one watt. The chip capacitor is often not sold individually, but in the views, often thousands and can cost less than $ 1 US dollar per 100 capacitors. The ceramic powder must be created in leaves with a specific thickness. This means that the powder must be combined with a carefully controlled amount of binding substances and solvents. After the man is mixed, the porridge is poured and then baked on the transport strips. Ceramic leaves are not yet shortened to size; The application and layering of the conductor must be the first.
Theconductive metal ink is made of powder metal, ceramics and solvents using overwhelming, mixing and finishing equipment called three cylinders. Ink or paste is then projected with specially patterned "silk screens" and dried hot air. At this point, the structure can be compared to green ceramics. The leaves are then layered in the correct way and number. After the pressure is applied to the unification of these layers into one structure, it is sliced into individual pieces.
further the pieces must be burned. The heart of this process is a furnace with a very slowly moving transport belt that carries pieces of tunnel with a very carefully profiled heating cycle, and if necessary controlled by the atmosphere. This step plays Larrole GE in the characteristics of finished devices. At this point, the terminals must be applied at both ends of the devices by means of powder metal and glass, with a solvent. They aresufficiently released.
Electropping is the final process that continues to test. Kloting takes place in layers, the first of which is a barrier layer of nickel, which protects the underlying equipment. Then, a can of the can prevent nickel corroding and improves the soldering compatibility during end use if the device is to be soldered. After all these steps, the device is tested. The values and tolerance of quality control are determined and carefully recorded, then the capacitors are packed and sold.
