What is a Castellated-Hole-PCB? A Castellated-Hole-PCB, also known as a castellated printed circuit board, is a type of PCB that features small, half-moon shaped holes along the edges of the board. These castellations allow for easy and secure connections between multiple PCBs or modules, creating a more compact and efficient design. Castellated-Hole-PCBs are commonly used in applications such as wearable devices, IoT modules, and small form factor electronics. Advantages of Castellated-Hole-PCBs Space-saving design Easy and Read more…

Introduction to PCB Design with Altium and Eagle Printed Circuit Board (PCB) design is a crucial aspect of electronic product development. Two popular software tools used for PCB design are Altium Designer and Autodesk Eagle. While both tools have their strengths, there may be situations where you need to use a pcbDoc file created in Altium with Eagle. In this article, we will explore the process of using Altium pcbDoc files with Eagle and provide Read more…

What is PDF-to-Gerber Conversion? PDF-to-Gerber conversion is the process of transforming a PDF file containing a printed circuit board (PCB) design into a Gerber format, which is the industry standard for PCB manufacturing. Gerber files are used by PCB fabricators to create the physical boards, as they contain all the necessary information about the layers, apertures, and coordinates of the PCB design. Why Convert PDF to Gerber? There are several reasons why you might need Read more…

Introduction to Thermal Relief BGA Pads Ball Grid Array (BGA) packages are a popular choice for high pin count integrated circuits due to their compact size and ability to accommodate a large number of connections in a small footprint. However, the high density of connections in a BGA package presents challenges when it comes to soldering the package to a printed circuit board (PCB). One key challenge is managing the thermal stress that occurs during Read more…

Understanding PCB Types and Materials PCB Types PCBs come in various types, each designed to suit specific applications and requirements. The most common PCB types include: Single-sided PCBs Double-sided PCBs Multi-layer PCBs Flexible PCBs Rigid-Flex PCBs PCB Type Description Applications Single-sided PCBs Conductive traces on one side of the board Simple, low-cost devices Double-sided PCBs Conductive traces on both sides of the board More complex devices, improved component density Multi-layer PCBs Multiple layers of conductive Read more…

What is a Blank PCB Board? A blank PCB (Printed Circuit Board) is a bare board without any components soldered onto it. It consists of a substrate material, typically FR4 (a composite material made of fiberglass and epoxy resin), with copper traces etched on one or both sides. These copper traces form the electrical connections between the various components that will be mounted on the board later in the manufacturing process. Blank PCBs come in Read more…

What is a PCB and Why are Blank PCBs Useful? A Printed Circuit Board, or PCB, is the foundation that allows electronic components to be connected together to create a functional electronic device or system. PCBs provide the conductive pathways, through copper traces, to electrically connect the various components. Blank PCBs are circuit boards that have the copper traces and pads already etched on but do not have any components soldered to them yet. They Read more…
