In PCBA processing, how does the Program “burn” into the Chip

In PCBA processing, in order to make the circuit board achieve the expected specific function, in addition to hardware, but also software support. There is software, it is necessary to add the “burning” program in the PCBA processing process— to “transport” the program to the IC.

PCBA IC Programming

1.Definition

The process of “moving” the program to the internal storage space of the chip is called burning.

2. Classification

Burning methods are generally divided into offline burning and online burning.

1. Offline burning:

IC offline burning is the process of “transporting” the program to the internal storage space of the chip, ‌ this process is usually divided into offline burning and online burning in two ways

1. ‌ Off-line burning means that the chip is burned with an external device (‌ such as a computer) ‌ disconnected. ‌ This burning method is suitable for chips that need to be programmed without a live communication connection. ‌ Off-line burning usually involves writing pre-programmed data directly to the chip, ‌ rather than transferring it over a real-time interface. ‌ This is useful in specific applications, ‌ where there is a need to ensure that the chip will work reliably under certain conditions (‌ e.g. high temperature, ‌ low temperature or harsh electromagnetic environment) ‌, ‌ or for large-scale batch programming on the chip production line. ‌

In addition, ‌ offline burning may also involve setting encryption parameters on the chip or burning some parameters, such as ‌ the IP address and port data of the WiFi module, ‌ to ensure the normal operation and security of electronic products.

2 ‌ This technology is essential to protect intellectual property and ‌ to prevent unauthorized access to or modification of the chip’s internal programs. ‌

In general, ‌IC off-line burning is a method to write programs or data directly to the internal storage space of the chip, ‌ without real-time connection to external devices, ‌ is suitable for applications requiring high security and reliability. ‌

2. Online burning:

Online burning refers to the process of correcting or upgrading the IC chip by automatic or manual means during the operation of the system ‌. ‌ This burning method does not need to remove the chip from the circuit board, ‌ directly on the circuit board operation, ‌ makes the function or performance of the chip can be updated or optimized in real time. ‌IC online burning is suitable for those who need to frequently update software or firmware of electronic products, such as ‌, such as digital electronic dictionaries, ‌ users after a period of time, ‌ can manually operate or automatically upgrade the product through the computer, ‌ to update the learning content or upgrade the system .This technology is very common in modern electronic products, ‌ especially in the field of frequent software or firmware update, ‌ such as smart wearable device, ‌ Bluetooth module, ‌ car electronic key, ‌ tire pressure monitoring system and so on.
