Pájení ponořením a pájená zařízení SMD

Dip Soldering and SMD Solered Devices Dip soldering and smd soldered devices are two different processing methods that are used to assemble electronic devices. Both methods use a reflow process that involves a gradual heating of the solder paste. When the reflow process is successful, the melted solder paste effectively bonds the mounted components to […]

Metody a procesy pájení čipů na deskách plošných spojů

Soldering Methods of PCB Chip Package and Processes Soldering is a critical part of a PCB chip package. Soldering processes involve a combination of techniques, including focused IR, convection, and non-focused IR. Each method involves a gradual heating of the package, followed by cooling the entire assembly. Soldering process Soldering is the process of joining […]

Úvodní informace o jednostranné a oboustranné montáži SMT

Introduction About Single-Sided and Double-Sided SMT Assembly Single-sided and double-sided SMT assemblies differ in terms of component density. Single-sided SMT assembly has a higher density than double-sided SMT assembly and requires a higher amount of heat to process. Most assemblers process the higher-density side first. This minimizes the risk of components falling out during the […]

Jak provést model výpočtu impedance PCB

How to Do a PCB Impedance Calculation Model Using a Smith chart The Smith chart is a useful tool when you want to determine the impedance of a circuit. It is a visual representation of the complex resistance versus frequency of an electrical circuit. It also shows the locus of impedance versus frequency, which is […]
