What is the Purpose of Plating Nickel on PCB?

The chemical element symbol of nickel is Ni. Because of its excellent physical, mechanical, and chemical properties, nickel has many applications in engineering and industry, such as anti-corrosion, increased hardness, wear-resistance, and magnetism. It is mainly used in alloy formulations, such as nickel steel, nickel-chromium steel, nickel-copper, etc. to increase its corrosion resistance and oxidation resistance. Because of its good oxidation resistance, it was often used to make coins in the...

OpenOCD on Raspberry Pi: Better with SWD on SPI

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 ...

The Formation and Prevention of Black Pad and Phosphorus-Rich Layers

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...

Reducing Time to Market for New Hardware Products with PCBway

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...

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...

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...
