What is a burner? What are the types of burners?

What is a burner? The burner is a tool that can become a programmer and write data for programmable integrated circuits. The programmer is mainly used for the programming (or brush writing) of chips such as MCU (including embedded) and memory (including BIOS). The programmer mainly modifies the program in the read-only memory. The programmer is usually connected with the computer and used with the programming software. Generally speaking, when it comes to the burner, most people think of CD-RW. Only electronic engineers know that the IC special burner used in factories and R & D units is another electronic product with earlier and more professional development.

In terms of function, the burner can be divided into universal burner, mass production burner and special burner. The special-purpose burner has the lowest price and less applicable chip types. It is suitable for programming with one or a kind of special chip, for example, it only needs to program pic series. The full-function universal type can generally cover almost (not all) all the chips that need to be programmed at present. Due to the troublesome design and high cost, the sales volume is limited, and the final price is very high. It is suitable for the situation that many kinds of chips need to be programmed.

Manual burner

The manual burner is connected in series with PC through USB and connected to LAN through network cable to realize local or remote PC communication. This process can run independently offline, easy to operate and easy to expand, so it is suitable for small batch operation.

Generally speaking, this kind of burner supports many models, but due to the limitations of the matched fixture test seat, it can not be used in other packages after it is only used in one kind of packaging, so the cost is high; However, this kind of burning method, offline burning, can avoid the loss of chip disassembly after burning and debugging, and off board burning is stable and efficient, which is suitable for small batch production.

In addition, this kind of burner has relatively complete functions, allowing users to organize common command sequences such as erasure, empty check, programming, verification and encryption into a single command completed in one step at will. It is worth noting that generally, the burner with more chip models is better, which can maximize the output ratio.

Automatic burning machine

Generally, the price of this kind of equipment is high. The equipment is controlled by microcomputer and takes materials with batch suction nozzle. The discharge structure can complete various operations alone.

The device can burn 30-80 chips at the same time. The fully automatic intelligent IC programming device designed by the device is suitable for the production of a large number of electronic products without human intervention. The machine will automatically alarm in case of abnormal conditions. The price of such equipment is high, and the list price ranges from 110000 yuan to 500000 yuan. Therefore, most of the purchased equipment are special burning plants or SMT lines.

UFS burner

UFS burner is a manual mass-produced IC burner, which can expand up to 96 burning seats, and the burning speed can reach 180 Mbytes per second; Of course, the actual burning speed varies from chip to chip.

At the same time, it can support multiple burners to operate together on the same PC, which can fully meet the needs of small batch copy operations. It is reported that the price of the UFS burner ranges from several hundred to 15000 yuan.

Online burning

Online burning is to paste the chip on the PCB before burning it. However, due to the flexibility of online writing (after the product is produced, you can temporarily burn different firmware according to the user's order).

When it comes to the advantages of online burning, it is suitable for mass operation, with high capacity and guaranteed security. It can realize FRB file encryption and effectively avoid hacker intrusion. Its disadvantage is that it is not easy to rework, which is easy to cause batch loss, faulty welding or component quality. Improper operation may cause unsuccessful burning, so its stability is low. However, due to the low cost of equipment, it has become the burning method selected by many manufacturers.

In summary, the burner is classified according to different chips and customer needs. There are special-purpose burners, such as single-chip microcomputer. Many manufacturers have their own single-chip microcomputer special-purpose burners, which are called single-chip microcomputer special-purpose burners. Most large companies engaged in IC burning generally use universal burners. In terms of function, the burner can be divided into universal burner, mass production burner and special burner. The special-purpose burner has the lowest price and less applicable types of chips. It is suitable for programming with a certain or a certain type of special chips.
