NXP Electronics components unboxing，humidity card changed color chip can used？

-Original content, please do not reprint.
Today we specially found the original MCU to unbox and show it to you.you can have deeper understanding of the chip's factory packaging， NXP's MCU has a relatively high market share and is widely used. If you have purchased this brand MCU, I hope this video provides you with some valuable information.

NXP unpacking


• First of all, we first understand the basic situation of this NXP through the label sticker on the outer box. When we open the box, red foam paper is wrapped on both sides to provide shock-proof protection and prevent the vacuum bag from being bumped and leaking. Some of the original and authentic NXP products use this type of foam paper.







• In addition to the original label on the vacuum bag, there is also a lot of information about the preservation of the components on the vacuum bag, which is very detailed. Let's cut open the vacuum bag and take a look at the packaging inside. After opening, remember to seal the vacuum bag back and store it as soon as possible to prevent the components from getting damp. In addition, if the humidity card is not blue, it means it is damp. When the circle is The color changes from blue to pink, indicating that the humidity in the package reaches or exceeds the relative humidity value corresponding to the circle. It needs to be baked and dehumidified before it can be used on the machine. When the vacuum is good, it usually does not get damp. The desiccant in the package may be because the MCU is a highly humidity-sensitive device, and the dryer is also relatively packaged. There is also a humidity card.detaile.

• When cutting the tape, remember to hold it down with your hands to prevent the tape from springing out too hard and knocking over the chip. There are also tray specifications next to the tray.Even though the chip we are unboxing today is 21 years old, due to proper storage, the pins are still bright in color without any oxidation, and the surface of the chip is smooth and clean, which looks very healing.

• Let's take a look at the silk screen，This material was produced in 21 years，The logo is Freescale，Even the new year is NXP's，These are the original MCUs of Freescale，The silk screen is still Freescale's logo，This is what you need to pay attention to when buying these materials，The second row is the version of the component, and the third row is the batch information，Here is 21 years and 43 weeks.







Can the chip still be used after the NXP chip humidity card changes color?

• After receiving components from suppliers, many people find that the humidity card inside the package has changed color. They will feel very worried. Can the chip still be used after the chip humidity card changes color?

• First of all, the discoloration of the humidity card will not affect the function of the product as long as the components are not oxidized. However, it may be that the vacuum packaging of the components leaked during the logistics process, causing moisture to enter the packaging bags of the components. At this time, you There will be some minor application problems during the welding process of the components. Of course, this can be solved. You only need to bake the components before using the product. Baking the components removes internal and external moisture from the components. When in use, it can reduce the number of component soldering, or the bulges inside the chip due to moisture, etc.
