In the midst of your holiday shopping, you probably came across the new Amazon Kindle Fire that’s selling for $50.
$50!
这是亚马逊在市场上的任何其他平板电脑的便宜两倍。对于50美元，您可以获得7英寸显示屏，1.3 GHz四核处理器，Wi-Fi，8 GB的存储空间以及后方和前面的摄像头。这不是最奇特的平板电脑，但用亚马逊自己的话来说，它是“a most sensible tablet。”
Let’s take a look inside to see just how明智这款新平板电脑确实是。
包装肯定会在敏感性的规模上获得A+。这是非常简约和高效的空间，因为它占用很少的零售空间。它在零售环境中也非常灵活，因为它可以悬挂或站立。
通常，消费电子产品将用某种模制纸浆托盘包装，但这只是一块纸板 - 一种更环保的解决方案，绝对比您的普通包装便宜。
This is what comes out of the package — tidy and simple! It是slightly disconcerting that the tablet was rattling around inside without a ton of structure, but it does look nice. Is Amazon making a statement about the durability of the Fire tablet?
The kindle is super easy to open, kept together by a ton ofsnap fits。
The button mechanisms on the outside are really awesome. This is a co-molded piece, made of rigid PC-ABS plastic on the outside, with little arms made of an elastomer material on the inside, designed to keep the feature from falling out of place after installation. I love this mechanism and use it all the time.
看着内部，套管是一个非常简单的塑料注塑零件，用PC-ABS作为材料，略带纹理和彩色（Vs.绘制）。
The middle of the mold is actually carved out by CNC (computer numerical control) milling. This is the big mystery of today’s teardown. We’re not entirely sure why Amazon would CNC this middle part, but our theory is that there was some sort of modification done towards the end. Maybe the battery was replaced for a thicker battery, which messed up the product assembly. All we know is that a rework had to be done; this happens all the time.
On the right you can also see the gigantic battery, manufactured by Amperex Technology in Hong Kong.
Below the battery is a真的便宜的小扬声器，直接焊接到主板上。当您建造50美元的平板电脑时，即使是单个连接器也会改变BOM的成本。亚马逊不会打扰多余的。
On the screen, we find a wide FPC (flexible printed circuit) ribbon that goes into a connector to the main board. There are so many pins on this thing!
在套管的另一侧，我们看到了大量的喷射销痕迹。许多弹出销都均匀地确保该零件在从模具中弹出时不会翘曲。还有很多肋骨可以为非常薄的后板增添刚度。
Under the shield we find the chips:
- Samsung KLM8G1GEND-B031- 数据存储芯片
- Mediatek ARM Mt8127A – SoC (system on chip)
- Mediatek MT6323LGA- 集成电路
这里的主要要点是，这件事的目的是便宜的。It only has 5 screws, really low-cost chips, a super cheap speaker, and minimalist packaging. We’re estimating the BOM cost to be just a bit below its retail price of $50. Amazon is not making much profit here, in the hopes you’ll also purchase their digital content once you have the device.
So if you’re looking for something really basic and shall we say, sensible, this Kindle Fire has your name on it.
