What is Low Volume PCB Fabrication? Low volume PCB fabrication refers to the production of printed circuit boards in small quantities, typically less than 1000 pieces. This is ideal for prototyping, small production runs, or custom projects where large quantities are not required. Request Alumina PCB Manufacturing Quote Now Why […]

What is PCB Etching? PCB etching is the process of chemically removing unwanted copper from a printed circuit board (PCB) to create the desired electrical connections. It involves applying a resist layer to protect the copper traces that should remain, then submerging the PCB in an etchant solution to dissolve […]

Introduction to PCB Stackups A printed circuit board (PCB) stackup refers to the arrangement of copper and insulating layers that make up a PCB. The stackup defines the number of layers, their order, thickness, and materials. Choosing the right PCB stackup is crucial for ensuring proper functionality, signal integrity, and […]

Why is PCB Incoming Inspection Important? PCB incoming inspection is a vital step in the electronics manufacturing process for several reasons: Identifying defects early: By inspecting PCBs upon arrival, manufacturers can identify any defects or issues before the boards are used in the assembly process. This early detection helps prevent […]

The Importance of PCB Inspection PCBs are the backbone of electronic devices, connecting and supporting various components to ensure proper functionality. However, during the manufacturing process, defects can occur due to a variety of factors, such as poor soldering, component misalignment, or contamination. These defects can lead to malfunctions, reduced […]

Why Choose Copper for PCBs? Copper is the most commonly used conductor material for PCBs due to its excellent electrical conductivity, thermal conductivity, and durability. Some key advantages of Copper PCBs include: High electrical conductivity enables efficient power transmission and signal integrity Good thermal conductivity helps dissipate heat for improved […]

Visual Inspection Visual inspection is the most basic and common method for PCB Quality Control. Trained inspectors visually examine the PCBs for any obvious defects or irregularities. This process can be performed manually or with the assistance of automated optical inspection (AOI) systems. Manual Visual Inspection In manual visual inspection, […]
