1. Small size of electronic products. The size of patch components is only about 1/10 of that of traditional plug-in components. Generally, after SMT patch processing, the size of electronic products is reduced by 40%~60%.2. Effective and low cost. SMT patch processing is easy to automate, improve p

There are many factors that affect the impedance of PCB boards, such as dielectric thickness, line width/line spacing, copper thickness, and dielectric constant. Let's take a look at the relationship between these factors and the impedance value of PCB boards.1. Dielectric thickness---is the mos

In general, if BGA packaging can be avoided in design, it should be avoided as much as possible, because BGA packaging is difficult to solder and the soldering inside the packaging cannot be checked.Circuit board short circuit: When the circuit board is soldered and aging, some circuit boards will b

Types of PCB materials.PCB materials are many, such as fiberglass, paper, metal, and plastic, and there are many, as well as high-frequency PTFE, etc.PCB typesA. Divided by materiala. Organic materialsPhenolic resin, fiberglass/epoxy resin, Polyimide, BT/Epoxy, etc. are all included.b. Inorganic mat

PCB (Printed Circuit Board), Chinese name is printed circuit board, also known as printed circuit board, printed circuit board, is an important electronic component, the support of electronic components, and the provider of electrical connections for electronic components. Because it is made by elec
