Automatic Test Equipment
ATE is the abbreviation of Automatic Test Equipment.In the semiconductor industry,it means an integrated circuit(IC) automatic test machine, which is used to test the integrity of integrated circuit functions. It is the final process of integrated circuit manufacturing to ensure the quality of integrated circuit manufacturing.

Edit the location of ATE in this section
In the manufacturing process of all electronic components (Device), there is a real need for counterfeit storage.This need is actually a process of experimentation.In order to realize this kind of process, a variety of test equipment is needed, and this type of equipment is the so-called ATE (Automatic Test Equipment).The electronic components DUT (Device Under Test) mentioned here, of course,includes the IC category,in addition,it also includes discrete components and devices. ATE exists in each link of the Front End and Back End,depending on the requirements of the process design.

Edit the role of ATE in this paragraph
In the process flow of components, there are various links that need to be tested according to the needs of the process.The purpose is to screen out defective products, prevent entering the next process, and reduce redundant manufacturing costs in the next process. These links need to be grasped by various physical parameters. These parameters can be light, electricity, waves, mechanics and other parameters in the real physical world.However,the most common ones are mostly electronic signals. ATE design engineers have to consider the most basic physical parameters of the electronic part, such as time, phase, voltage and current.It is what electronics say, signal processing. In addition, for example, LCD, PDP (plasma display) need to test the function of the light-emitting part, then it is necessary to measure the optical parameters.

Edit the core function structure of this paragraph
Generally speaking, there are two major categories:

1.The core test structure: inherited from the traditional test technology,detection technology,automatic implementation of signal processing (electronic signal measurement). For different DUT test proposals, the core test structure will also be different. 

 2.Computer control structure:The processing speed and ability depend on the computer power at that time.In fact,computer technology has become a general technology. For a set of ATE, a high-index computer is not necessarily the best computer.To meet the needs of the system,coordination is the best standard.In fact,the price of complex ATE equipment is equivalent to that of the baby of a giant root dwarf,compared to the price of an advanced high-index server.Generally speaking,the role of computer technology,the coordination of control systems, the injection path of control signals,the collection and processing of control data,and so on.In other words,the computer's management of the system's hardware and software is a two-pronged approach---being a father and a mother,and both eating and drinking Lhasa.Therefore,general-purpose computers are no longer suitable,so FA computer technology has been produced in history. 

However, this still cannot meet the high-speed and large-scale requirements.Therefore, the experts simply broke the traditional structure of the computer, and even produced a dedicated CPU and a dedicated ChipSet.All this is just to prove a simple truth repeatedly,it is the need of production that drives the progress of technology.

The above is the introduction of ate (Automatic Test Equipment) automatic test machine. Ipcb is also provided to PCB manufacturers and PCB manufacturing technology.
