0805 A Common Semiconductor Packaging

0805 is a common form of semiconductor packaging that consists of three parts: a metal pin frame, a plastic top cover, and a plastic bottom cover. This packaging form has the advantages of small size, low power consumption, and good electrical performance, and is therefore widely used in various electronic devices. So, what is the mystery of 0805 packaging size? Let's unravel this mystery together

We need to understand the basic parameters of the 0805 package. According to the standards of the International Electrotechnical Commission (IEC), the length of the 0805 package is 1.27mm x 0.625mm, the height is 0.56mm, and the width is 0.765mm. Among them, length and height refer to the total length and height of the plastic sealed lower cover and pin frame; Width refers to the width of the pin box. These parameters are all obtained through precise measurements, ensuring the accuracy and consistency of the 0805 package

We need to know how to calculate the number of pins. Due to the fact that the 0805 package is a four sided pin package, its number of pins can be calculated using the following formula: number of pins=4+4+3+3=16. Among them, the first four pins are digital polarity pins, and the last three pins are analog signal pins. These pins are connected to the corresponding circuits on the chip through gold wires

We need to understand how to choose appropriate resistors and capacitors to achieve matching. Due to the different voltage and current requirements of different types of components, it is necessary to choose appropriate resistors and capacitors for matching based on specific situations. Generally speaking, a multimeter can be used to test the parameters of components and adjust them based on the test results

We need to know how to weld and assemble. Due to the compact and lightweight packaging of 0805, professional welding equipment and techniques are required for welding and assembly. During the welding process, attention should be paid to avoiding issues such as short circuits and virtual soldering to ensure the normal operation of the circuit

After understanding the above knowledge, we can better understand the mystery of 0805 packaging size. Of course, this is just the tip of the iceberg, and to truly master this skill, continuous learning and practice are necessary
