What is Solder Mask and Why is it Important? Solder mask, also known as solder resist or solder stop mask, 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 […]

What is Mixed Assembly? Mixed assembly is a manufacturing process that combines both automated assembly lines and manual assembly stations. This approach offers several advantages over traditional assembly methods, allowing for greater flexibility, efficiency, and cost-effectiveness in the production process. In a mixed assembly system, automated machines handle repetitive, high-volume […]

Introduction to SMT Line Surface Mount Technology (SMT) has revolutionized the printed circuit board (PCB) manufacturing industry since its introduction in the 1960s. SMT line, an essential component of PCB manufacturing, is a highly automated and efficient production process that involves placing surface mount devices (SMDs) onto a PCB. This […]

Introduction to PCB Shields PCB shields, also known as electromagnetic interference (EMI) shields or radio frequency (RF) shields, are essential components in electronic devices that protect sensitive circuits from unwanted electromagnetic interference. These shields are designed to enclose and protect specific areas of a printed circuit board (PCB), preventing external […]

What is a PCB Protective Coating? A PCB protective coating is a layer of material applied to the surface of a printed circuit board to shield it from environmental hazards such as moisture, dust, chemicals, and extreme temperatures. These coatings act as a barrier between the sensitive electronic components and […]

Introduction to PCB Manufacturing in Thailand PCB manufacturing is a critical component of the electronics industry, and Thailand has become a preferred destination for many international companies seeking high-quality PCBs. The country’s PCB industry has grown significantly over the past few decades, driven by the increasing demand for electronic devices […]

What is a Solder Bridge? A solder bridge, also known as a solder short, is an unintentional connection between two or more soldered points on a printed circuit board (PCB) that should not be connected. This unwanted connection is typically caused by excess solder during the soldering process, resulting in […]

What is a Purple PCB? A Purple PCB, or Printed Circuit Board, is a specialized type of circuit board that has a distinctive purple color. Unlike traditional green PCBs, Purple PCBs are designed to offer unique benefits and characteristics that make them suitable for specific applications. Characteristics of Purple PCBs […]

Introduction to PCB Assembly PCB (Printed Circuit Board) assembly is the process of soldering or mounting electronic components onto a printed circuit board. It is a crucial step in the manufacturing of electronic devices, as it transforms the bare PCB into a functional electronic assembly. PCB assembly involves several processes, […]
