How Peelable Soldermask Works Peelable soldermask is applied to a PCB in the same way as traditional permanent soldermask, typically through screen printing or spray coating. However, the composition of peelable soldermask is different, allowing it to be removed cleanly from the PCB surface when required. Composition of Peelable Soldermask […]

What is LPI Solder Mask? LPI solder mask is a photosensitive polymer coating that is applied to the surface of a PCB. It is designed to selectively expose and cure when subjected to ultraviolet (UV) light, creating a permanent protective layer on the PCB. The LPI solder mask is typically […]

How Peelable Soldermasks Work Peelable soldermasks are typically made from a polymer-based material that is applied to the PCB surface using screen printing, spray coating, or dip coating methods. The mask is then cured using heat or ultraviolet (UV) light, depending on the specific material used. Once the soldering process […]

How Does Powder Spray Coating Work? The powder spray coating process works by using electrostatic attraction to adhere powdered polymers to a substrate, which are then melted and cured in an oven to form a protective or decorative coating. The main steps in the process are: Powder preparation: The powdered […]

What is solder mask? Solder mask, also known as solder resist or solder stop, is a thin, protective layer applied to the copper traces and pads on a PCB. Its primary purpose is to prevent solder from adhering to areas where it is not intended to be, thus preventing short […]

Introduction to Electrostatic Powder Spray Electrostatic powder spray is a coating technique that has gained significant popularity in various industries due to its numerous advantages. This method involves applying a dry powder coating material to a substrate using an electrostatic charge. The electrostatic charge causes the powder particles to adhere […]

What is Solder Resist? Solder resist, or solder mask, is a protective coating applied to the copper traces of a PCB. Its primary functions are: Preventing solder bridges from forming between closely spaced solder pads Protecting the copper traces from oxidation and corrosion Providing electrical insulation Improving the aesthetics of […]

Understanding Solder Mask Breakoff and Its Implications Solder mask, also known as solder resist or solder stop, is a thin layer of polymer applied to the copper traces of a printed circuit board (PCB). Its primary function is to protect the copper traces from oxidation, prevent solder bridges from forming […]

Introduction to Colorful Soldermask In the world of printed circuit boards (PCBs), soldermask plays a crucial role in protecting the copper traces and preventing short circuits. Traditionally, green has been the most common color for soldermasks. However, with the advent of ColorfulSoldermask, PCB designers now have the opportunity to bring […]

How Solder Mask Dam Works The solder mask dam technique is implemented during the PCB manufacturing process. Here’s a step-by-step explanation of how it works: PCB Design: During the PCB design phase, the copper pads for components are defined with a specific size and shape. The solder mask layer is […]
