What is a Small Outline Integrated Circuit (SOIC)? A Small Outline Integrated Circuit (SOIC) is a surface-mounted integrated circuit (IC) package that has a smaller footprint than a dual in-line package (DIP). SOICs are rectangular in shape and have gull-wing leads on two sides. They are widely used in various electronic applications due to their compact size, low profile, and good electrical performance. SOICs come in different sizes and lead counts, making them suitable for Read more…

Introduction to QFP Packages and Solder Paste Quad Flat Package (QFP) is a surface-mounted integrated circuit package with leads extending from each of the four sides. QFP packages are widely used in various electronic applications due to their compact size, high lead count, and good thermal and electrical performance. To ensure reliable solder joints between the QFP leads and the printed circuit board (PCB) pads, it is crucial to apply the correct volume of solder Read more…

Introduction to PCB Recreation Printed Circuit Boards (PCBs) are essential components in modern electronics. They provide a reliable and efficient way to connect electronic components and create complex circuits. However, there may be situations where you need to recreate a PCB, either because the original design files are unavailable or you want to modify an existing board. In this article, we will explore a method to recreate a PCB using a scanner and Inkscape, a Read more…

Introduction to PCB Stencils PCB stencils are an essential tool in the electronics manufacturing industry. They are used to apply solder paste onto printed circuit boards (PCBs) before components are placed and soldered. This process ensures precise and consistent solder paste application, which is crucial for the proper functioning of the electronic device. What is a PCB Stencil? A PCB stencil is a thin metal sheet, typically made of stainless steel or nickel, with laser-cut Read more…

Composition-Based Solder Types The most common types of solder, based on their composition, include: Lead-Based Solder Lead-based solders contain lead (Pb) as the primary component, along with tin (Sn) and sometimes other elements. The most common lead-based solder is 63/37 (63% tin, 37% lead), known for its low melting point and excellent wetting properties. However, due to health and environmental concerns, lead-based solders are being phased out in many applications. Advantages of Lead-Based Solder Low Read more…

What to Look for in a PCB Manufacturer When evaluating PCB Manufacturers, there are several key factors to consider: Capabilities – What types of PCBs can they manufacture? This includes things like max number of layers, material options, min trace/space widths, hole sizes, surface finishes, etc. Pricing – How competitive are their prices, especially for the quantities and turn times you need? Are there any setup/tooling fees? Turn Times – How fast can they manufacture Read more…

What are Castellated Pads? Castellated pads, also known as castellated holes or castellations, are a type of surface mount technology (SMT) used in printed circuit board (PCB) design. These pads are essentially plated through-holes (PTHs) that are cut in half along the edge of the PCB, creating a series of semi-circular pads that resemble the battlements of a castle, hence the name “castellated.” Castellated pads offer several advantages over traditional SMT pads: They allow for Read more…
