What is IC programming in PCB assembly?
What is IC Programming in PCB assembly? IC Programming is Programming to transfer programs to the procedure space for storing within the chip. Typically speaking for the first IC, there’s no burned record. However, there ought to be even a definite code (such as some chips have a novel serial variety, boot part, etc.).
What Is the Best Time to Do IC Programming?
You may wonder what is the best time to do IC programming. IC programming can be completed before or after PCB assembly. It depends on the following conditions. For prototype or low-volume production, it is best to program the IC after PCB assembly. However, for mass production, it is best to program the IC before PCB assembly with a proper IC Programmer.

Why Does IC Need To Burn?
Why not take a glimpse at the understanding of the intended operation of the board? Code and program matching support is needed except for hardware. Then the matter arises: Can you figure out the way to “transfer” the Program to THE TIME of C? I am certain you already understand that the solution is “programming,” or some folk’s decision is “burning.” Programming to transfer programs to the procedure space for storing within the chip.
Types of IC Programming: Offline Programming and Online Programming
Two kinds of programming will be unfolded including offline programming and online programming.
For offline programming, if it’s compatible with chips completely different|in several|in numerous} packages via exploitation of different adapters, then the chip will be used beside the adapter to end the complete IC program burning.
Because the adapter could be a correct fixture, thus different adapters ought to be chosen if the IC or package is different.
Today, a lot of and a lot of BGA and QFN are widely used, which could be a trend of the chip package, as an example the chip of EMMC, the price of that isn’t low. If there’s one thing that goes wrong within the production take a look at the method, you ought to take the chip out of the adapter and reprogram it per the desired method, which can waste tons of your time and energy, and the price is extremely high.
All of those area unit pressing cases within the production of PCBA. If the board isn’t temperature-resistant enough, then the chip can simply deform once removed, which will increase the danger of scrap.
What are the most common problems of chip burning? In the process of chip burning, there are always various problems. So, the following is the core of the collection of some of the most common problems, engineers have to see if they have been in the move.
The following are the problems that usually happen in the IC program process:
The Tips for Programming IC Chip: Flip Over and Find A Solution
From the above enumerated common problem, it can be seen that the chip included a wide range of problems, the process of re-disk to find out the cause of many engineers feeling bald. So, engineers want to “appropriate medicine”, and find out the cause of burning failure, which can be divided into the following aspects to analyze and find.
First of all, engineers want to identify the cause of the burning failure, starting with the tools used and the way of burning. The different burning ways will appear burning obstacles are different, and the solution is also a certain different.
For example, if it is online burning, first check if the chip has virtual welding, bad reading, and so on; In the process of chip collection, check whether there is incomplete burning, interruption, and so on.
The so-called off-line burning is through a variety of special adapter seats, the chip off-line burning, and then installed on the board of production. Due to the low versatility of the adapter and fixture, this burning method is more stable, but the cost is higher.
Still, some engineers choose to burn. And this kind of burning once there is a burning problem should start from two aspects of the investigation.
(1) If the contact is not sensitive and the speed of reading is too slow, please check if the burning tool is too old to use or used frequency is too high;
(2) Please check whether there is a burning option support this model in the burning library of the burning tool, if so, please confirm whether the IC part No and the software model are accordant;
(3) Check whether the USB cable and the burning tool are unreadable or incompatible;
(4) The burner selected is a domestic or homemade simulator, engineers need to consider whether the burn tool is compatible with the chip model regarding the burning tool is a domestic or homemade simulator
(5) Pay attention to the service life of the chip recording fixture, generally speaking, there are limited usage times for the chip burning so the life span of the fixture is time limited. So if there is poor contact and other glitches, all because of the burning tool seat. So we should pay attention to the lifespan of the IC burning fixture.
(1) Please check whether there were some programs installed before which affect the program file, which will cause the instability of the IC chip burning.
(2) Please check the format of the chip program is not matching with the format which the IC chip requires.
(3) Please check whether the burning tool driver is compatible with the driver.
(4) please check whether the certificate of the burning driver is expired.
(5) Please check whether the brand of the program which is installed is different from the burning tool, if the brand is different, check whether it is compatible or not.
After eliminating the above hardware and software problems, what remains is the problem of human operation. For the chip that burns error, the ID detection function can be removed manually, and read or erase, programmed, and verify to see whether it can succeed.
The online collection is a large volume operation, efficient and high cost of burning, burning directly after the board and then sending PCBA to the test machine test. The entire production process is fully automated, which makes it easy for the product program to do online simulations at a less mature stage and make appropriate adjustments to the program.
Although the cost of online collection is relatively low, the operator’s technical requirements for the operator is very high, even though the cost of online collection is not high. Because it requires a very professional engineer to finish the burning process because ordinary persons cannot finish such complete and professional work.
So, if such kind of IC chip burning problem happens, we should try to find out the reason from the following aspects.
The Core Seed Summary
Although the online burning method is more efficient and lower cost, suitable for batch operation, most engineers generally choose this method; however, the core son here to remind you, engineers, in online burning, should be a small number of machines to do burning verification, to ensure that there is no problem before mass operation, to avoid irreversible large-scale losses. Because, if the original quality problems after the machine, it will be easy to appear after-sales suppliers will not return the situation.

Frequently Asked Questions
IC programming is a chip as a processor that requires a program to work to miniaturize all components into one or several integrated circuits; an integrated circuit that can receive coded instructions at one or more of its ends, execute this instruction, and output a signal describing its state, and this process of storing the program into the chip is known as IC programming.
As mentioned earlier in the article, IC programming can be completed before or after PCB assembly. It depends on the following conditions. For prototype or low-volume production, it is best to program the IC after PCB assembly. However, for mass production, it is best to program the IC before PCB assembly.
First connect the burner data cable, and put the corresponding IC holder into the burner holder; then turn on the computer and burner power.
Run the burn-in software: Double-click the icon “GANG-08” with the mouse, (different burn-in holders correspond to different burn-in software).
Select the IC brand: After the program startup screen appears, click on the “Device” menu to bring up the IC brand selection table, and then select the corresponding brand of the IC to be burned, and then click “OK”.
Select the IC model: At this time, the IC models produced by the company where the IC is to be programmed appear, select the IC model and click “Run”. At this time, if the burner holder shows that we need to select jumper, then follow the computer prompts to jump the wire, jump the wire and click “OK”. If the burner holder does not show the need for jumpering, then go directly to the burn-in interface.
Transfer the software to be burned: Click the menu “File”, select “Load File To Programmer Buffer”, then select the software to be burned, click “Open “, then select “00”, and finally click OK.
Check the software check code (Buffer Checksum): after the transfer of software, the Buffer Checksum will appear after the four-bit check code.
Programme the software: Click the “Program” button, put the IC to be programmed into the IC holder, install the IC and press the burn-in button on the burner holder. When the burning is completed, if the programming is successful, “OK” will be displayed, and if the programming fails, a red “Error” character will be displayed. If each indicator of the burner holder connected to the IC lights up, it indicates that the IC programming is successful.
Mark the IC: Put a sticker on the IC that is programmed OK, and put the IC that failed to be programmed into another burn-in socket and reprogram it again. If the IC is damaged, put it into the defective box and make a mark.
First, the electronic product has a microcontroller or ARM controller. In the production process, there is no program in the control chip at the beginning, to execute the operation of the microcontroller or ARM chip according to our designed function, it is necessary to burn the program execution file written by the project into the controller chip of our electronic products.
Secondly, the corresponding parameters need to be burned.
Third, we need to burn files, such as font, pictures, ringtones, animation, and other files.
In general, IC programming is intended to ensure the normal operation of the microcontroller system or ARM chip, as well as the safe operation of the essential files and parameters.
The time taken to perform IC programming is affected by various aspects such as the chip itself, the size of the burn-in program, and the speed of the burner.
Yes. There are three types of programming for IC programming in Viasion.
The cost of performing IC programming is related to the following factors.
First, the cost will be determined by the type of IC, distinguishing whether the IC is conventional or unconventional and whether the IC is BGA, QFN, or SOP.
The next factor is capacity. Nowadays, there are many ICs with 64G of storage space, such as navigation systems, which contain maps and other information, and sometimes use 4G or 8G of storage space. The burn-in time for such ICs is longer. A longer time will increase the cost of burning equipment, so the price will be relatively more expensive. If the burning time is short, the IC programming cost will be relatively cheaper.
Another factor is the amount of IC programming. If the customer just needs a few prototypes, then of course it will be a little more expensive. If the customer needs a large quantity of IC programming and the volume is stable, we can also sign an agreement with the customer or carry out long-term cooperation and we can make the price very favorable.
The final factor that determines the cost is whether to make marks. If different color marks are made, the operation will be more troublesome, so the price will be relatively high.
The performance of PCB products can be well improved and high efficiency of operations can be ensured.
There is no dedicated certification for IC programming, but we follow ISO 9001:2015 and other industrial standards in our IC programming process.
There are the normally steps to finish a IC chip programming:
- Find a suitable a IC programmer;
- Connect the IC programmer to a computer and install relative IC programmer software;
- Copy the custom software into the integrated circuits.
