What is the IC programming in the PCB assembly?

IC programming in the PCB assembly refers to the process of downloading the program code into an integrated circuit board chip. This printed circuit board assembly process is usually done by a programmer or programming software to ensure that the IC performs specific functions according to the PCB design requirements. Known as the core of the most important electronic component circuit today.

What is the IC burning record?

Burning is the process of writing data or programs into a programmable device. Programmable devices can be various types of chips or memory, such as microcontrollers, FPGA (field programmable gate array), EEPROM (electric configurable programmable read-only memory), etc. Burning allows these devices to perform specific functions.

Burn is the process of writing the target data into a programmable device through specific software and hardware means. Programming devices can be a variety of electronic chips, memory, etc., and the data in the burning process can be firmware, software programs, media files, etc. By burning it, we can write data to the target device, enabling it to perform the corresponding functions according to our needs.

What is PCBA IC programming?

off-line programming

By being compatible with a variety of adapters of different packaging chips, the chips and adapters can be used together to realize the IC programming. The adapter itself is a kind of precision treatment, different chips, and different packaging need to choose different treatments. At present, the widely used EMMC and other chips tend to be BGA, QFN, and other small packages, and the price of packaging adapters is very high.

If the PCBA test mistakes, the maintenance production back, also wants to remove the chip from the adapter, by the provisions of the process to write, there may be some other problems in the process of PCBA processing, such as PCB circuit board material TG low, dismantling chip can’t withstand high temperature, fragile, the chip time-consuming, at the same time increase the risk of scrap.

Online programming

Online programming is the standard communication bus of the chip, such as USB, SWD, JTAG, UART, etc. The interface is fixed, and fewer connection pins are needed when programming. Because the interface communication rate is not high, the programming can be completed by using ordinary lines. If an error occurs during production testing, production backtracking can be immediately modified and programming restarted without removing the chip. Because the online programming is through the wired connection, it not only saves the production cost but also improves the programming efficiency. Now most PCBA factories will choose to burn online to burn the IC.

Conclusion

IC programming is about programming the code and loading it into an integrated circuit, which can be done in two ways, namely, offline and online programming. It is done following the given procedure and using the special tools discussed in this article.
