How to efficiently and quickly produce automotive components in the face of high heat recording and strict performance requirements

A glamorous car has an array of electronic components, each of which has its own chip, and each chip has its own separate program to burn. In the face of such a large amount of programming and strict performance requirements of the automotive class, what kind of solution does the smart engineers use to deal with it?

When it comes to the various parts of the car, friends who don’t know beforehand tend to be a bit worried. As a matter of fact, with the advancement of the industrial level, the structure of automobiles has become more and more complicated. A fast-moving car on the street is no longer a simple cargo that was run on the engine a hundred years ago. Various intelligent electronic devices are covered with the body of a modern car. The complexity of the car directly poses a problem. How can so many parts be produced efficiently and quickly? How to burn a large number of chips is a worrying question.

Listen to me saying this, you may have doubts, each part of the car electronics has its own manufacturer, it is good to produce their own products, what are the difficulties? This is to start with the development of automotive electronics. When a product is still in the process of development, the original 2-link emulator is often used. When entering the production process, the original 2-link emulator will be used for burning. But as a professional device for simulation, the simulator is not good at burning, it is difficult to achieve the 100% yield of automotive electronics, which is very embarrassing.

then what should we do? If the simulator is more capable of emulation, then programming using a programmer is a very appropriate choice. However, the choice of programmers is both offline and online. Different programming methods will affect the design of the factory production process, tooling and fixtures:

1, offline burning

The so-called off-line burning is a production method in which the chips are burned offline by various dedicated adapters and then mounted on the board. This approach greatly improves reliability and stability compared to previous emulator burn-in ratios. But the adapter itself is also a kind of precision fixture that is difficult to generalize between different chips, which adds cost. Moreover, once the unqualified product wants to be re-programmed, it is difficult to remove the chip that has been burned on the board and re-burn it. After burning it, it is necessary to go to the patch again, which in turn adds another cost. Therefore, although offline burning has advantages, the short board is also very obvious. Take a look at the various adapters in the picture below, which is prohibitive.

2, online burning

At present, the advantage of online burning is unique. In order to ensure the stability of burning, there is no need to customize the adapter, and the wire can be used. If you find any errors, you can correct them in time. You don't have to take the complicated steps of removing the patches again, which reduces the cost and improves the efficiency.

More importantly, the production line is now developing towards automation. More and more manufacturers are adding functional test machines such as ICT and FCT to the production line. The production method using automatic fixtures and online burning can be omitted in the burning stage. Manual operation, directly burned after the board is attached, and then the PCBA is sent to the test machine for testing, and the entire production process is fully automated, which can greatly improve the production efficiency.

Based on the deep technical accumulation of the programmer industry in the past 20 years, ZLG Zhiyuan Electronics has broken through the shortcomings of traditional online programming, such as low efficiency, single chip type, and inability to go offline. It has launched a new mass-produced online programmer P800isp, which is the first to achieve full offline. Multi-channel online programming. With a complete automatic control protocol, it can provide interface functions and DLLs for users to carry out secondary development, and quickly realize automatic control, becoming the leader in many online burning programs.
