If you’re an electronics hobbyist and you hold a new PCB with your bare hands, usually you will spend several minuets staring at it. You want to capture all the art behind it and to see if there is any new technique should be adapted in your next PCB design, but sometimes you can find some marks, and can’t figure out their functionality. In this micro blog I will introduce 8 common PCB marks like these.Eight Common PCB Marks:From Right to Left: Stamp Holes – Types of Holes- Solder Thief pad – Fi...

Sneaky tricks to align stray bits into proper bytesThe setup that we see above… Debugging nRF52 with a Raspberry Pi running VSCode and OpenOCD… Was impossible just a week ago!OpenOCD connects to nRF52 for flashing and debugging by running Arm’s SWD protocol over GPIO Bit Banging. OpenOCD was sending data to nRF52 one bit at a time… Works fine when OpenOCD is the only task running, not when it’s sharing the CPU with VSCode and other interactive tasks!That’s because multitasking skews the precise ...

In our daily SMT soldering operations, we often find that ENIG surface-treated boards are prone to two fatal problems: nickel corrosion and phosphorus-rich layers. Once such problems occur, they often cause a lot of batch solder joint reliability problems. Because these two types of problems are very concealed, the current reproduction is generally not easy to detect. Once found, most of them are too late. The damage and losses have already been caused and may not be able to make up.There are ba...

The path to bring a new hardware product to market is filled with a lot of challenges that large corporates are usually able to march past using qualities like experience, relationship, money, and people's expertise, which are usually non-existent in the arsenal of startups and individuals. More often than once, we've seen these challenges bury several good ideas/products in the valley of development, and for those who manage to get them over the production finish line, they are usually behind s...

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...

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...

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...

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...

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...
