Which IC chips need burning programming? Cost factors affecting burning

IC is an integrated circuit, referred to as chip for short. All enterprises engaged in the production of electronic products will use IC, but IC is divided into active chips that need to be burned and passive chips that do not need to be burned. In all cases where active chips are needed, IC burning is required. However, if the general chip is not a single chip microcomputer or programming chip, it does not need to be burned. Such chips as single chip microcomputer or arm need to be burned. Let's take a look at the specific introduction.

Generally, the IC that can be burned includes MCU class and storage class. The storage class is relatively single, mainly storing some system programs and other things. MCU class not only has storage action, but also has data processing ability, so the function of MCU class is relatively complex.

MCU class will involve many parameter settings and other proprietary functions. MCU class IC setting error will lead to failure to start after loading. Storage IC also has some parameter settings, such as encryption, protection, etc. MCU is mostly PIC MCU, which can be divided into single burning OTP and multiple burning MTP.

Single burning OTP means one-time programming. After the program is burned into the IC, it cannot be changed, reset or burned again. If you burn the wrong data, some can cover the burning, and some can be recovered, but the probability of recovery is very low, so we should be very careful.

Most memory chips can be rewritten and burned repeatedly. As for the parameter setting inside, it needs to be set according to the needs of customers. For example, software engineers will require the performance of products on their boards to meet the standards. Generally, when helping customers burn, they will first ask about the customer's relevant parameter settings. During the burning process, they will also determine whether the customer's relevant parameter settings are burned correctly.

Precautions for IC chip burning:

1. Be careful when placing the IC to avoid damaging the IC and burning base.

2. The IC must not be installed reversely. The IC with the board removed must first check whether there is a tin short circuit on the pin, otherwise it is easy to damage the burning base.

3. The burning personnel must be trained before taking the post. Other computer programs must not be used during burning.

4. In case of adverse phenomena, immediately feed back to the management personnel for solution.

What factors are related to the burning cost?Next, let me tell you about the factors that determine the burning cost. Generally, if the customer burns on behalf of the customer, the burning cost will first be determined according to the model of the IC, whether the IC is conventional or unconventional, and whether the IC is BGA, QFN or SOP.

For ICs with many pins, dense pins and difficult packaging contact points, the burning cost will be relatively expensive. IC pins such as SOP are less, which is relatively cheaper.

The type of IC is a big determinant. For example, SPI flash is more conventional, so its burning cost is cheaper, but if it is a single chip microcomputer or CPLD, it may be more expensive.

The next factor that determines the cost is the capacity. At present, many ICs achieve 64g. ICs such as navigation system contain map and other information. Sometimes they need 4G and 8g storage space. The burning time of such ICs will be relatively long. A long time will increase the cost of burning equipment, so the price will be relatively expensive. If the burning time is short, the cost of IC burning will be relatively cheaper.

If an IC is conventional or unconventional, the cost of burning will also be determined. For example, some ICs rarely burned by customers such as MCU. Its burner has few resources, and its consumables are relatively expensive, and the price will be relatively high.

Another factor that determines the cost is the amount of burning. If the customer only has a few proofs, it will certainly be more expensive. If the number of customers is large and stable, we can also sign an agreement with customers or long-term cooperation. We can make the price very favorable.

The last factor that determines the cost is whether to mark it? In general, the marking part of the current automatic burning may have to be marked in different colors sometimes, which may be more troublesome to handle, so sometimes the price in this aspect will be relatively high. For example, EMMC is relatively expensive because of its large capacity. TSOP or SOP are relatively conventional. It is easier to burn and cheaper.
