What is a Gerber File? Gerber files, also known as Gerber image or Gerber format files, contain the essential information needed to manufacture a printed circuit board (PCB). They are generated from PCB design software like Altium Designer and sent to PCB fabricators. A complete Gerber file package includes: Copper […]

Introduction to Solder Mask Bridges A solder mask bridge is a thin layer of solder mask material that spans across two or more adjacent pads or traces on a printed circuit board (PCB). The purpose of the solder mask bridge is to prevent solder from flowing between the pads during […]

Introduction to Solder Mask Dam Solder mask dam is an important feature in printed circuit board (PCB) design and manufacturing. It involves creating a barrier or “dam” around specific areas of the PCB using solder mask material. The purpose of solder mask dam is to contain the flow of liquid […]

What is Solder Mask? 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 purpose is to protect the copper traces from oxidation, prevent solder bridges from forming between closely spaced […]

Introduction to Solder Mask Solder mask, also known as solder resist or solder stop, is a crucial component in the manufacturing of printed circuit boards (PCBs). It is a thin, protective layer applied to the copper traces and pads on a PCB, leaving only the areas that need to be […]

What is Soldermask? Soldermask, also known as solder resist or solder mask, is a thin layer of polymer applied to the copper traces on a PCB. Its primary purpose is to protect the copper from oxidation, prevent solder bridges, and provide electrical insulation. Soldermask also helps to define the exposed […]

What is Black Pad and Why is Preventing it Important? Black pad, also known as “black pad syndrome” or “weak solder joint”, is a defect that can occur during the PCB Assembly process which results in poor solder joints and unreliable connections between components and the printed circuit board. It […]

What is Solder Mask and Why is it Important? Solder mask, also known as solder resist or solder stop mask, is a thin lacquer-like layer of polymer usually applied to the copper traces of a printed circuit board (PCB) for protection against oxidation and to prevent solder bridges from forming […]

Introduction to PCBA Quality Criteria Printed Circuit Board Assembly (PCBA) is a crucial process in the manufacturing of electronic devices. The quality of the PCBA directly affects the performance, reliability, and longevity of the final product. To ensure that the PCBA meets the required standards, it is essential to establish […]

What is Soldermask Expansion? Soldermask expansion, also known as solder resist expansion or solder mask pullback, refers to the amount by which the solder mask opening on a printed circuit board (PCB) is enlarged beyond the copper pad dimensions. In other words, it is the value applied to surface mount […]
