Understanding 10 Layer PCBs Before diving into the selection process, let’s first understand what a 10 layer PCB is and its advantages. What is a 10 Layer PCB? A 10 layer PCB, as the name suggests, consists of ten conductive layers laminated together with insulating material. These layers include: Top […]

Introduction to LPI Soldermask Application Liquid Photo Imageable (LPI) soldermask is a crucial component in the manufacturing of printed circuit boards (PCBs). It serves as a protective layer that covers the copper traces on the PCB, leaving only the desired areas exposed for soldering components. The application of LPI soldermask […]

What is Curtain Coating? Curtain coating is a high-speed, non-contact coating method used to apply a thin, uniform layer of liquid onto a moving substrate. In this process, a continuous curtain of coating liquid freely falls onto the substrate which is moving underneath the curtain. As the substrate passes through […]

How Peelable Soldermask Works Peelable soldermask is typically applied to PCBs using screen printing or spray coating techniques. The mask is composed of a polymer material that is formulated to withstand the high temperatures associated with soldering while remaining easy to remove once the process is complete. The main functions […]

Understanding the Powder Spray Process The powder spray process consists of several key steps that ensure the proper application and adhesion of the coating material to the surface. These steps include: Surface Preparation Powder Application Curing Surface Preparation Before the powder coating can be applied, the surface of the object […]

Introduction to Electrostatic Powder Spray Electrostatic powder spray is a coating process that uses electrically charged particles to create a uniform and durable finish on various surfaces. This technology has gained popularity in recent years due to its numerous benefits, including improved efficiency, reduced waste, and enhanced coating quality. In […]

Introduction to Eye-catching Red Solder Resist Solder resist, also known as solder mask, is a protective coating applied to printed circuit boards (PCBs) to prevent solder bridges and short circuits during the soldering process. While green is the most common color for solder resist, red has become increasingly popular due […]

Introduction to Solder Paste Mask Solder paste mask, also known as solder mask or solder resist, is a protective layer applied to printed circuit boards (PCBs) during the manufacturing process. Its primary purpose is to prevent solder from adhering to unwanted areas of the PCB, ensuring that the solder only […]

How PCB Stencils Work PCB stencils work by providing a uniform layer of solder paste on the PCB pads. The stencil is placed on top of the PCB, and solder paste is spread across the stencil using a squeegee. The solder paste passes through the openings in the stencil and […]
