What is Microprocessor
Processors usually refer to microprocessors, microcontrollers and digital signal processors. Microprocessors (MPUs) usually represent a powerful CPU, but they are not chips designed for any specific computational purposes that already exist. Such chips are often the core CPUs of personal computers and high-end workstations. The most common microprocessors are Motorola’s 68K series and Intel’s X86 series.

In the electronic component industry, crystal triode and field effect transistor are two kinds of highly respected electronic components. Especially in switching power supply, they are favored by electronic engineers. But how to choose crystal triode and field effect transistor, crystal triode for short, and field effect for the newly introduced purchasing? Like transistors, transistors, which have the characteristics of amplification and switching, are one of the core devices in electronic devices and are widely used. Triode and field effect transistor have the same characteristics and shape, but their working principles are different. Common triode is a current control device, and two-field effect transistor is a voltage control device.

Many companies’ purchasing will find that when they get the parts in the BOM provided by engineers to purchase materials, suppliers will often ask more carefully, otherwise they will not know what kind of materials to supply you. In serious cases, the purchased materials will not be used. Why is this the case? The problem is that many engineers who are not experienced enough have not completed the model of the device. The following is an example to illustrate what the complete device model is like.

Basic Knowledge of Electronic Components Procurement
In electronic manufacturing enterprises, the standard procurement process can be divided into two parts: strategic procurement and order coordination. Strategic procurement includes supplier development and management, while order coordination is mainly responsible for material procurement planning, duplicate orders and delivery payment. This organizational structure is very similar to the sales system. Many sales companies have also established professional sales support departments to handle a large number of repetitive orders. The development and management of suppliers is the core of the whole procurement system, and its performance is also related to the performance of the whole procurement department.
