Understanding the Basics of PCB Manufacturing Before we dive into the manufacturing process, let’s establish a foundational understanding of PCBs. A PCB is a flat board made of insulating materials, such as fiberglass or composite epoxy, with conductive copper traces etched onto its surface. These traces form the electrical connections between components, allowing for the…

Types of PCB drilling defects There are several types of drilling defects that can occur during the PCB Manufacturing process. These include: Misaligned Holes Misaligned holes occur when the drill bit does not enter the PCB Substrate at the correct location. This can be caused by a variety of factors, including: Incorrect drill file data…

Introduction to Flip chip Technology Flip chip technology, also known as controlled collapse chip connection (C4), is a method for interconnecting semiconductor devices, such as integrated circuit (IC) chips and microelectromechanical systems (MEMS), to external circuitry with solder bumps that have been deposited onto the chip pads. The solder bumps are used to connect the…
