Improper Solder Paste Application One of the most frequent problems in LED PCB Assembly is applying the solder paste improperly. If too much or too little solder paste is used, or if it is not applied evenly, it can lead to issues like bridging, tombstoning, or insufficient solder joints. Some common causes of improper solder paste application include: Cause Description Stencil misalignment The solder paste stencil is not aligned correctly with the PCB pads Incorrect Read more…

Introduction to PCB Coils A PCB (Printed Circuit Board) coil is an essential component in many electronic devices, particularly in applications involving wireless power transfer, RFID systems, and electromagnetic sensing. These coils are designed to create a magnetic field when an electric current passes through them, enabling the transfer of energy or the detection of changes in the surrounding electromagnetic environment. PCB coils offer several advantages over traditional wire-wound coils, including: 1. Compact size and Read more…

Introduction When it comes to assembling printed circuit boards (PCBs), there are two primary methods used in the industry: wave soldering and reflow soldering.

What are Gerber Files? Gerber files are the standard file format used to describe the printed circuit board (PCB) layers and drilling information needed for PCB fabrication. They are named after the Gerber Scientific Instrument Company which originally developed the file format. Gerber files provide a clear, unambiguous, and standardized way to communicate PCB design information between PCB design and manufacturing. A complete set of Gerber files will include individual files for each copper layer, Read more…

Introduction to Mouse Bites PCB Mouse bites PCB is a fabrication technique used in the production of printed circuit boards (PCBs). This method involves creating small, evenly spaced perforations along the edges of a PCB panel, allowing for easy separation of individual PCBs after the manufacturing process. The term “mouse bites” refers to the appearance of these perforations, which resemble the bite marks of a mouse. Advantages of Using Mouse Bites PCB Technique Cost-effective: Mouse Read more…

Introduction to IC Packaging Integrated Circuit (IC) packaging is a crucial aspect of electronic device manufacturing. It involves encasing a semiconductor chip in a protective material, such as plastic or ceramic, to provide mechanical support, electrical connectivity, and protection from the environment. The package also serves as an interface between the chip and the printed circuit board (PCB) on which it is mounted. IC packaging has evolved significantly over the years to keep pace with Read more…

Types of PCBA Equipment Solder Paste Printer A solder paste printer is used to apply solder paste onto the PCB pads where components will be placed. The machine uses a stencil with apertures that match the PCB pad layout. The solder paste is then squeezed through the stencil onto the board, ensuring precise and consistent application. Specification Description Print Speed 50-200 mm/s Print Accuracy ±0.025 mm Stencil Size Up to 29″ x 29″ Vision System Read more…

Introduction to PCB Soldering PCB soldering is a crucial process in the manufacturing of electronic devices. It involves the joining of electronic components to a printed circuit board (PCB) using a molten metal alloy called solder. The quality of the solder joint determines the reliability and performance of the electronic device. One of the most important aspects of PCB soldering is the formation of solder balls. What are Solder Balls? Solder balls are small spheres Read more…
