汽车芯片 S9S12XS128J1MAA 拆箱

今天我们要开箱汽车芯片

在这个长方形的纸箱前面，是熟悉的芯片包装盒

芯片的盒子表面有品牌标志，这个盒子上印有 NXP 的标志

在芯片标签信息旁边，具体信息我们后面再说

Let's look at the small box icon. next to the triangle with a hand pattern is the circuit board anti-static label

next to the triangle with a hand pattern is the circuit board anti-static label

The side one also has three small icons

The pattern of the cup represents fragile items, take it lightly

Umbrella-shaped pattern, refers to can not be caught by water, afraid of moisture

The arrow refers to the side to swing up

Cut the tape at the seal with the knife and open the carton

The foam board above is used to protect the chip and is a bodyguard

The vacuum electrostatic bag is also one of the bodyguards of the chip, and the chip is hidden inside

The chip is more protective in the tights, so the vacuum is very important

Next, let's talk about the tag information mentioned earlier

First, the brand: NXP

Below it is the lot encoding

date of manufacture

quantity

product model

product code

The msl, abbreviated for Moisture Sensitivity Level, means moisture sensitivity grade

3 is to show that this material is less than or equal to 30°C / 60% RH 168 hours workshop life

The small circle of PB is illustrated as a lead-free device，Compliance with the EU RoHS specification，Comply with the ROHS3 specification

Cut open the vacuum bag and remove the chip

The chip holds a black anti-static tray, with desiccant and 3 points outside the humidity indicator card

The humidity card is blue, indicating that there is no damp, and the humidity card will become pink. 

If the chip is opened, it can be put in the drying cabinet together with the humidity card, and then stored in vacuum.

Cut off the black braid band and open the tray cover

The chip is new without scratches, bright feet, looks very complete，The chip is particularly fragile, and the pin is easy to be damaged, especially the QFP pin is too much, so we should pay special attention to it

We use the suction pen to take the chip, remember to suck it firmly and then pick it up

The size of the chip is 14 mm x 14 mm, and the thickness of the chip is 2. 3 mm

Each chip weighs at 935. 5 (mg)Can you call it the actual shoot?

There is a spacing of 0.65 mm between each pin

The screen print on the chip is Freescale's logo

Here, although Freescale was acquired by nxp, because the chip is 9S12 series, its predecessor is FREESCALE, so the brand logo on the carton and the label are NXP, while the LOGO screen of the chip is still in FREESCALE

In addition, the model

Many friends are curious to say that they bought S9S12 but the chip screen is MC9S12, whether they buy fake goods, it is not so, this is a normal situation

 What is the difference between S9S12 and MC9S12, we will expand to tell you later.

The origin of the chip is printed on the back of the circle, which is made in Malaysia

At the same time, from the seagull wing (L) type pin can be seen, is QFP packaging, this knowledge point in the previous QFP chip packaging physical explanation of the video mentioned ~ chip packaging confused friends, you can go to the home page to view oh ~
