闪亮的芯片是假的吗？小指和闪亮的有什么区别？为什么现在大多数芯片都是小指的？ 芯片的引脚还含有金吗？
没有引脚的芯片就像一个人失去了口耳，无法交流或接收来自外界的信息。这表明 pin 的重要性
是。有些人的听力和视力更好，而另一些人可能是近视或难以清晰地听到。正如芯片上引脚的材料会影响其
性能，好芯片上的引脚质量也非常出色。之前的筹码含金量很高，引脚和内部都有金线。目前的芯片有很多
针脚中的金子较少，甚至一些塑料针都是由材料制成的。当然，收集芯片并提炼它们的生意仍然存在，这意味着有一些
包含金筹码的零件，但或多或少。
碎屑粉脚和油光脚
几年前，有一种方法可以通过查看芯片的脚是粉红色还是有光泽来识别原始芯片。
主要原因是当今大多数芯片都使用镀锡工艺，我们通常将其称为粉末脚。所以，很多人都认出了这个粉脚。
有些朋友可能会说，脚亮的薯片算不算过时了？他们会是假的吗？不一定是这样;这两种类型的潜在客户都有自己的存在理由。
闪亮的脚芯片并不意味着它已经完全淘汰，因为它具有更好的导电性，并用于许多消费电子产品。然而，它的耐腐蚀性
稍逊一筹，使其更容易被氧化。因此，后来人们采用了一种叫做镀锡的工艺，也就是我们所说的粉脚。镀锡支脚
更适合于环境要求更高的电子设备中的应用，如汽车和工业自动化。
为什么闪亮的脚会失去人气？
Then why does the lead of our chip look so powdery? Mainly due to a mysterious potion. This additive is called tin chloride plating solution. This mysterious potion causes the
leads to produce very fine and uniform tin grains during plating, which is the source of this frosted effect,
In the past, when we sold chips, we said the shinier the better; the shinier it was, the more authentic it seemed. Nowadays, people are actually afraid of buying such shiny shins;
they have a greater belief in these powder-shiny shins. In fact, there might be a misunderstanding that it is a less advanced process, but in reality, its manufacturing process is
actually more complex and challenging. These powder-shiny shins are actually easier to make.
Then why do these shiny pins, which look more attractive, gradually lose their appeal? The main reason is that while these pins have a more beautiful and smoother surface,
the solder tends to spread easily when welding. High temperatures can affect the quality of the weld, whereas the rough surface of these powder pins helps form a mechanical
bond with the solder. In other words, they have better adhesion and are less likely to spread, making them easier to weld.
It's precisely because the chip pin is so beautiful and smooth that it has become its own drawback. Will this process be phased out? Not necessarily; with the emergence of
new soldering techniques, people may improve the welding performance of tin-plated components, making it very likely that these shiny pins will return to the market.
