How Does Peelable Soldermask Work? Peelable soldermask is typically made of a latex-based or synthetic rubber material that is applied in liquid form and then cured to create a solid, yet flexible coating over the PCB surface. The key characteristics of PSM are: Thermal stability: Withstands high temperatures during soldering Read more…
What is a PCB Inductor? A PCB inductor, also known as a printed circuit board inductor, is a passive electronic component that stores energy in a magnetic field when an electric current flows through it. It consists of a coil of conductive material, usually copper, wound around a core or Read more…
Introduction to Rogers and Teflon PCB Materials Printed Circuit Boards (PCBs) are essential components in modern electronics, providing a platform for mounting and interconnecting electronic components. The choice of PCB material plays a crucial role in determining the performance, reliability, and cost of the final product. Two popular high-performance PCB Read more…
What is a Presensitized PCB? Presensitized Printed Circuit Boards (PCBs) are copper clad boards that have been pre-coated with a light-sensitive resist material, also known as photoresist. This coating allows for the creation of intricate circuit patterns on the PCB through a process called photolithography. Presensitized PCBs offer several advantages Read more…
1. Cold Solder Joints Cold solder joints occur when the solder fails to melt completely or when there is insufficient heat transfer between the solder and the components. This results in a dull, grainy appearance and a weak mechanical and electrical connection. To avoid cold solder joints: – Ensure the Read more…
Why Are PCB Test Coupons Important? PCB test coupons play a crucial role in ensuring the quality and reliability of the final PCB product. By including test coupons in the manufacturing process, PCB fabricators can: Monitor Process Consistency: Test coupons help manufacturers ensure that their production processes remain consistent and Read more…
Introduction to Solder Mask and Its Importance Solder mask, also known as solder resist or solder stop mask, is a thin protective layer applied to the copper traces of a printed circuit board (PCB). Its primary purpose is to prevent solder from adhering to areas where it is not intended, Read more…
What is Electrostatic Powder Coating? Electrostatic powder coating is a popular method used for applying a protective and decorative finish to various metal surfaces. This process involves the use of a dry powder that is electrically charged and sprayed onto the surface of the metal object. The charged powder particles Read more…
Understanding the Powder Spray Process The powder spray process is a type of coating method that uses a dry powder made from finely ground particles of pigment and resin. The powder is electrostatically charged and sprayed onto the surface of a substrate, which is typically made from metal, plastic, or Read more…
The Allure of Eye-catching Red in PCB Design When it comes to printed circuit board (PCB) design, the choice of solder mask color can have a significant impact on the overall aesthetic appeal and functionality of the board. While green is the most common color for solder masks, other colors, Read more…
