Comparison of the IC substrate and PCB

Comparison of the IC substrate and PCB

IC substrate and PCBs (printed circuit boards) are two common hardware elements in electronic product design. While they are similar in some ways, they differ greatly in design, functionality, and application. Understanding the difference between the two is important for electronics engineers.

How to avoid the PCB tombstone in PCBA process?

How to avoid the PCB tombstone in PCBA process

The PCB tombstone , also known as the Manhattan or drawbridge effect, is a chip (passive) component assembly defect situation. The cause of the PCB tombstone is that the melting time of the solder paste at both ends of the part is inconsistent, resulting in uneven force at both ends of the chip component, which is relatively light in mass and will cause one side to roll up under the action of stress.

Multilayer PCB design: an introduction to the basics

Multilayer PCB design

The circuit board can be divided into single-side, double-layer and multi-layer PCB according to the number of layers, and the multi-layer board refers to the circuit board with more than 4 layers. For many miniaturized products and high-speed products, multilayer boards are used, such as mobile phones, routing, switches, etc. So, what are the advantages of multilayer PCB? What is multilayer PCB design? How to design multi-class PCB? What do I need to pay attention to? This article will explain them all below.
