应该注意的是，由于通过空气对流散热，外部 PCB 层比内部层实现更好的热传递。反过来说，内部电介质不能很好地导热，这就解释了为什么内部走线比外部走线宽。

Printed circuit boards (PCBs) have come a long way over the years. Electronics design engineers must stay aware of the latest ...

Secondly, interposer PCB technology addresses signal integrity and power consumption issues. By utilising interposer technology, signal pins can be directly connected to the interposer layer, reducing ...

That left very little room for traces on the 2-mm-wide arms, so the PCBs had to have four layers, which raised eyebrows at the PCB house when [Sasa] submitted the design. Such an airy and open ...

to help you on your way to that cool looking PCB build. Silkscreen layers in yellow, solder mask opening in red The first step is to get your bitmap, whether you create it yourself, or download it ...

“Interposer routing is much easier, as the number of components is drastically reduced compared to the PCB,” says Andy Heinig, head of department for efficient electronics at Fraunhofer IIS/EAS. “On ...

The images were collected exclusively from actual PCB defects found on the inner and outer layers of boards after etching, using the equipment at Guangzhou FastPrint Technology Co., Ltd.
