What is a Solder Mask Made Of? Solder masks are typically made of a polymer-based material, such as epoxy or acrylic. These materials are chosen for their excellent electrical insulation properties, durability, and resistance to heat and chemicals. The most common solder mask materials include: Liquid Photoimageable Solder Mask (LPSM): A photosensitive liquid polymer that is applied to the PCB and then exposed to UV light to cure and harden. Dry Film Photoimageable Solder Mask Read more…

What is Solder Wicking? Solder wicking is a process that utilizes a specialized braided copper wire to absorb and remove excess or unwanted solder from a soldered joint or component. The braided wire, which is typically coated with a flux, is heated using a soldering iron. When the heated braid comes into contact with the molten solder, it wicks away the solder through capillary action, leaving a clean surface behind. How Solder Wicking Works The Read more…

What is PCB Recycling? PCB (Printed Circuit Board) recycling is the process of recovering valuable materials from discarded or end-of-life PCBs. PCBs are an essential component of electronic devices, including computers, smartphones, televisions, and various other consumer and industrial electronics. As technology advances and electronic devices become obsolete at a faster rate, the amount of e-waste generated globally has been increasing at an alarming pace. PCB recycling plays a crucial role in minimizing the environmental Read more…

An Inside Look at the PCB Manufacturing Process Printed circuit boards, or PCBs, are the backbone of modern electronics. These thin, flat boards are used to mechanically support and electrically connect electronic components using conductive pathways, tracks, or signal traces etched from copper sheets laminated onto a non-conductive substrate. PCBs are used in virtually all electronic products, from simple devices like digital clocks and calculators to complex computer systems and sophisticated medical equipment. While PCBs Read more…

Understanding Solder Paste Slump Definition of Solder Paste Slump Solder paste slump is defined as the undesired flow or spreading of solder paste after it has been deposited onto the PCB pads through a stencil printing process. In other words, it is the tendency of the solder paste to lose its original printed shape and geometry over time, especially when exposed to elevated temperatures or prolonged storage periods. Slump can occur in both the horizontal Read more…

Understanding PCB Thickness PCB thickness refers to the distance between the top and bottom surfaces of the board. It is typically measured in either millimeters (mm) or mils (thousandths of an inch). The thickness of a PCB plays a significant role in its mechanical strength, electrical properties, and overall functionality. Common PCB Thickness Measurements PCB thickness is commonly expressed in either metric or imperial units. Here are some standard measurements: Metric (mm) Imperial (mils) 0.4 Read more…

Introduction to Solder Paste Testing Solder paste printing is a crucial step in the surface mount technology (SMT) assembly process. It involves depositing solder paste onto printed circuit boards (PCBs) using a stencil and a printing machine. The quality of the solder paste printing process directly impacts the reliability and functionality of the final electronic product. Therefore, it is essential to test the solder paste printing process to ensure that it meets the required standards Read more…

Introduction to Flex-Rigid PCBs Flex-rigid PCBs are a unique type of printed circuit board that combines the best features of both flexible and rigid PCBs. These hybrid boards consist of multiple layers of flexible and rigid substrates that are laminated together to form a single board. The flexible layers allow for bending and folding of the PCB, while the rigid layers provide structural support and stability. Flex-rigid PCBs offer several advantages over traditional rigid PCBs, Read more…

History of Surface Mount Technology The origins of SMT can be traced back to the 1960s when IBM introduced the first surface mount components for their mainframe computers. However, it wasn’t until the 1980s that SMT gained widespread adoption in the electronics industry. The introduction of smaller, more reliable components and the increasing demand for portable electronic devices drove the transition from through-hole technology (THT) to SMT.
