Solder mask: everything you need to know

A solder mask is a protective coating on printed circuit boards that prevents oxidation. The traditional green coating you see on PCBs is a solder mask. Some circuit boards also use different colored solderless masks. The material of the solder mask can be, for example, epoxy resin. The solder mask must also be resistant to the fluxes and cleaning agents used. Resin is a good choice for a solder mask because it is durable, effective against moisture and insulates, maintains a good appearance over time, and can withstand high temperatures. In addition, it does not conduct electricity.

Thermal management techniques for printed circuit boards

We will focus on design techniques that enable better thermal management. In this article, we will discuss design techniques that improve thermal management, including some common methods for removing excess heat from a printed circuit board.

What is behind the abbreviations OEM, EMS, PCB and PCBA

Are you in innovation or start-ups? Do you have your own vision of selling a brand new product that includes electronic components? Perhaps terms like OEM, EMS, PCB and PCBA are confusing to you at the moment. Alternatively, you don't know who to contact to place your order. Today's article will help you navigate the terminology. Electrical engineering has technical terms just like other industries, and it's a good idea to understand the specifics to avoid misunderstandings between customers and suppliers. At the same time, we'll tell you who to approach to ensure that your expectations are met.

What is HDI PCB?

Beyond the technological marvels of the 21st century, HDI DPS is certainly one of the biggest contributing factors to our increasingly digital world. The HDI printed circuit board is used in everything from smart devices to spacecraft.

What are FLEX PCBs?

What is a FLEX PCB and how does it improve product design today? A flexible printed circuit board, also called a flexible printed circuit board (FPC), has different properties than a rigid printed circuit board due to the different type of base material, which expands the number of applications where it can be used.
