IC Programming

What is IC Programming?

IC programming refers to the process of programming integrated circuits (ICs) such as microcontrollers and FPGAs. Key aspects of IC programming include:

Programming Languages

IC programming typically involves using hardware description languages such as VHDL or Verilog, or low-level languages like assembly or C. High-level languages like C++ or Python can also be used in conjunction with the appropriate compiler/tools.

Programming Tools

Programming ICs requires the use of tools such as compilers, simulators, and debuggers to write, validate, and troubleshoot IC program code. Popular vendor tools include Xilinx ISE/Vivado, Altera Quartus, Keil MDK, IAR EWARM, and others.

Programming interfaces

ICs need to be programmed via standard interfaces like JTAG, SPI, I2C, etc. using programmers/debuggers. For microcontrollers, on-chip bootloaders may be leveraged as well.

Programming cycle

An iterative cycle of coding, compiling, simulating/emulating, and debugging is followed. The code is ultimately flashed into the IC’s memory to configure its functionality.

Testing & verification

The programmed IC must be rigorously tested for correct functionality, timing, power, etc. Simulation, emulation, and formal verification techniques help.

Debugging

Debugging may be needed to identify and fix bugs in the program code. In-system debugging capability is often provided via JTAG interface.

So in summary, IC programming refers to the process of writing, testing and optimizing code for an integrated circuit using appropriate languages, tools and techniques. It enables configuring the IC to perform desired functions.

The main method of IC programming

IC programming, also known as “programming” or “burning,” is the process of transferring the program or firmware into the internal storage space of an Integrated Circuit (IC) or microchip. This critical step is essential to enable the chip to perform its designated functions and tasks within electronic devices. There are two main methods for IC programming: offline programming and online programming.

Offline Programming

Offline programming involves using specialized IC programmers with adapters to support chips in different packages. Adapters are precision fixtures designed to accommodate various chip types and packages, such as small and flat BGA, QFN, and the widely used eMMC chips. Each chip package requires a specific adapter, and the price of these adapters can be significant.

While offline programming offers versatility in supporting different chip types, it has some drawbacks. In case of errors during production PCBA testing, the chip needs to be removed from the adapter and re-programmed, leading to time and energy waste as well as additional costs. Moreover, removing chips from adapters can pose risks of damaging the chip due to insufficient temperature resistance, potentially resulting in scrapped PCBAs.

Online Programming

Advantages
Online programming utilizes the chip’s standard communication bus, such as USB, SWD, JTAG, UART, etc. The interface for online programming is typically fixed, requiring fewer pins to be connected during the programming process. Due to the lower interface communication rate, general cables can be used for programming without significant power consumption.

Benefits
Online programming offers substantial advantages in PCBA manufacturing. It enables reprogramming of faulty PCBAs without chip disassembly, resulting in cost savings and improved programming efficiency. With the increasing trend towards automation in production lines, online programming becomes particularly advantageous. Integration of functional test machines like ICT and FCT allows for a fully automated production process, significantly enhancing efficiency.

Importance
Online programming is a critical factor for PCBA manufacturers in terms of precision, production efficiency, cost-effectiveness, and quality control. It plays a vital role in evaluating process precision, production efficiency, costs, quality control measures, scalability, and capital investment. Embracing online programming enables manufacturers to streamline production, reduce expenses, and uphold high-quality standards, positioning them competitively in the industry. Adoption of online programming maximizes the potential for automated production, elevating overall performance in delivering reliable and cost-effective PCBA solutions.

Third: eMMC Programming Solution Highleap Company offers an advanced eMMC programming solution to address the specific needs of mobile phone products. The eMMC specification, established by the Multimedia Card Association, simplifies memory design by integrating NAND Flash chips and control chips into a single chip through multi-chip packaging (MCP).

The eMMC solution provided by Highleap Company offers several advantages for mobile phone manufacturers. By utilizing eMMC chips, manufacturers can avoid the need to redesign specifications due to different NAND Flash vendors or process generations. This significantly reduces time-to-market and R&D costs for new products, accelerating the product launch.

NAND Programming Solution

NAND programming addresses the unique programming requirements of various NAND flash memory devices. NAND flash memory is used in a wide variety of applications from consumer electronics to industrial systems due to its high density and cost-effectiveness.

Highleap Company’s NAND programming solution is designed to handle a wide array of NAND Flash devices, such as SAMSUNG (K9F1G08), TOSHIBA (TC58NVG0S3), HYNIX (HY27), and more, with different footprints, packages, and configurations.

NAND Flash memory stores data by charging storage cells, and bit flipping may occur due to threshold voltage drift, often caused by “program disturb.” The memory is organized into blocks, each consisting of multiple pages with Main and Spare Areas. The Spare Area contains ECC data, bad block information, and other essential data for error correction and management.

Highleap Company’s expertise in NAND programming includes support for large-volume and multi-variety projects, ensuring programmed NAND Flash devices meet strict industry standards and client specifications.

MCU Programming Solution

MCU (Microcontroller Unit) programming encompasses burning ICs for single-chip controllers. OTP MCU (One-Time Programmable MCU) can be programmed only once and is typically burned by the manufacturer before product assembly, with the data remaining unalterable. In contrast, MTP MCU (Multi-Time Programmable MCU) allows for multiple programming and erasing cycles, often using built-in FLASH memory that can be programmed tens of thousands of times.

The programming room environment must adhere to strict anti-static measures due to the electrostatic-sensitive nature of chips. Employees in the chip room must wear static wristbands and anti-static clothing, and anti-static table mats are used on work surfaces. The room’s humidity should be maintained within a proper range (50%-60%) to minimize static electricity effects.

Co-Planarity Check

In IC programming, Co-planarity Check refers to the inspection of whether the pins of an IC chip are on the same plane, ensuring that the pins have the same height. This is a crucial inspection step because if the pins of the chip are not on the same plane, it may lead to connection issues or poor soldering during the Printed Circuit Board Assembly (PCBA) process.

Why is Co-planarity Check necessary?

Soldering Reliability: Co-planarity Check ensures that the pins of the IC chip have the correct contact area when soldered to the PCB, avoiding situations where some pins cannot be properly soldered due to varying pin heights, thus enhancing soldering reliability.

Electrical Connectivity: The co-planarity of the pins directly affects the electrical connection between the IC chip and the PCB. If the pins are not on the same plane, it may lead to unstable signal transmission or even electrical disconnection, affecting the overall functionality of the circuit.

Chip Protection: Co-planarity Check also helps to ensure that the chip’s pins are not subjected to excessive force during the soldering process, preventing pin damage or breakage due to significant height differences.

Mechanical Stability: Co-planarity is essential for the secure mounting of the IC chip on the PCB. If the pins are not on the same plane, it may lead to inadequate fixation of the chip on the PCB, causing shifting during transportation or usage.

In conclusion, Co-planarity Check is a critical step in guaranteeing the soldering quality, electrical connectivity, and overall stability of IC chips. Through this inspection, the correct and reliable operation of IC chips on the PCB can be assured, thereby improving the quality and performance of PCBA.
