Introduction to 4×4 Keypads A 4×4 keypad is a matrix-style input device commonly used in electronic projects, such as microcontroller-based systems, to provide a user-friendly interface for data entry. The keypad consists of 16 buttons arranged in a 4×4 grid, allowing users to input numbers, letters, and symbols. This comprehensive […]

Introduction to HDI PCBs High Density Interconnect (HDI) Printed Circuit Boards (PCBs) are a type of circuit board that offers higher wiring density than traditional PCBs. HDI PCBs have finer lines and spaces (<100 μm), smaller vias (<150 μm), and capture pads (<400 μm), and higher connection pad density (>20 […]

How AXI Works X-ray Imaging Principles AXI systems work by generating X-rays and directing them through the PCBA being inspected. As X-rays pass through the board, they are attenuated differently depending on the density and thickness of the materials they encounter. Denser materials like metals absorb more X-rays compared to […]
