Get to Know the ENEPIG — A type of the PCB surface finish

The Electroless Nickel Electroless Palladium Immersion Gold(ENEPIG) process is the earliest surface treatment process developed by Intel. By adding a palladium plating layer between nickel plating and pure gold plating, the nickel plating is separated from the gold plating layer to isolate the migration of nickel to the surface gold layer, and the thickness of the gold plating layer can be reduced to less than 0.1um. Because metal palladium is wear-resistant and has a higher hardness than hard g...

High Power Standalone Digital AC Dimmer Using STM32

By Hesam Moshiri, Anson BaoThis project is only free for personal and non-commercial useAC loads live with us! Because they are everywhere around us and at least home appliances are supplied with the mains power. Many types of industrial equipment are also powered with the single-phase 220V-AC. Therefore, we frequently face situations that we need to have full control (dimming) over an AC load, such as a lamp, an AC motor, a vacuum cleaner, a drill, … etc. We should know that controlling an AC l...

How to avoid the negative effects of vias in high-speed PCB design

The basic concept of viasVia is an important part of multilayer PCB. The cost of drilling usually accounts for 30% to 40% of the cost of PCB. Simply put, each hole on the PCB can be called via. From a functional point of view, vias can be divided into two categories: one is used as an electrical connection between layers, the other is used for fixing or positioning devices. In terms of technology process, these vias are generally divided into three categories, namely blind vias, buried vias, and...

What is PCB Tombstone?

IntroductionThe tombstone phenomenon is that during welding process of the MLCC and PCB, one end of the MLCC leaves the welding area and is inclined or standing upright. The main reason is the unbalanced wetting force at both ends of the MLCC during the welding process. The main factors that produce unbalanced wetting force are:(1) Both ends of MLCC cannot be melted at the same time;(2) The pad design is unreasonable. According to the mechanical mechanism, it is proposed to keep the surface of t...

Corrosion Protection With Parylene

A natural process, corrosion enacts chemical/electrochemical reactions that degrade and gradually destroy materials or components within a functional environment. The outcome can be dangerous and costly to repair. For printed circuit boards (PCBs) and similar assemblies, corroded electrical contacts can cause potentially life-threatening mechanical malfunction of aerospace/automotive/industrial systems during operation; corroded medical implants may disrupt pacemaker function or lead to blood p...

Inrush Current Limiter (Soft Starter) for AC/DC Loads

By Hesam Moshiri, Anson BaoInrush current/Switch-ON surge is the maximal instantaneous input current drawn by an electrical device when first turned on. Inrush current is much higher than the load’s steady-state current and that’s the source of many problems such as fuse blowing up, load failure, load’s lifetime reduction, sparks at the switch contacts … etc. The figure below shows the inrush current phenomenon captured on the Siglent SDS1104X-E oscilloscope. The long spike is clear. In this art...
