IC programming is the process of transferring a computer program into an integrated computer circuit. Older types of IC include PROMs and EPROMs
PCBA processing technology has become increasingly mature and has a wide range of applications. It plays a key role in today’s various intelligent devices. To make the board understand the function of the expected design and the hardware, it needs the matching support of software and program.
Offline programming is compatible with chips in different packages by the different adapters. The chip can be used with the adapter to achieve program burning.
The adapter is a precision fixture. The different chips and packages need different adapters.
Nowadays, the package is developing in small and flat BGA, QFN, etc., such as the widely used Emmc chips. At the same time, the price of those adapters is not low.
If there is an error in the production pcba test, you need to remove the chip from the adapter and re-program according to the prescribed process, which will waste time, energy and add additional costs.
There are some emergencies in PCBA production. If the temperature resistance of the circuit board is not sufficient, the chip will be deformed when you remove the chips, which will increase the risk of scrapping.
The online programming uses the chip’s standard communication bus, such as USB, SWD, JTAG, UART, etc. The interface is generally fixed, and there are fewer pins to be connected during programming.
Since the interface communication rate is not high, general cables can be used for burning without high consumption.
Because the online burning is programmed by wire connection, if an error is found during the production test, the faulty PCBA can be traced back and re-burned without disassembling the chip. This not only saves production costs but also increases the efficiency of programming.
More importantly, the production line is 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.
In the manual operation, the board is attached after it’s directly burned, and then the PCBA is sent to the test machine for testing. The entire production process is fully automated, which can significantly improve production efficiency.
Therefore, in PCBA processing, the advantages of online burning are significant. It is becoming one of the industry’s important indicators to measure PCBA manufacturers’ process precision, production efficiency, cost, quality control, scale, and capital.

Third eMMC programming solution
eMMC is a standard specification for embedded memory established by the Multimedia Card Association. It is mainly for mobile phone products and simplifies the design of memory. It uses multi-chip packaging (MCP) to package NAND Flash chips and control chips into one chip. eMMC has multi-function, including storage and boot function that replaces NOR Flash.
The biggest advantage is that mobile phone manufacturers do not need to redesign specifications due to NAND Flash vendors or different process generations, and need to deal with NAND Flash compatibility and management issues. Mobile phone customers only need to purchase eMMC chips and put them in mobile phones, which not only shortens the time-to-market and R&D costs of new products, but also accelerates the product launch.
PRO-808 eMMC/SD duplicator has high performance, PC-free independent operation. It also has a single female port and 8 target slots, supports MMC version 4.3/4.4/4.41 protocol, and compatible with eMMC/MMC/RS-MMC cards. eMMC is currently on the market.
