What is reflow soldering?
Reflow soldering is a widely used method for soldering surface mount components onto printed circuit boards (PCBs). It involves the use of solder paste, which is a mixture of tiny solder particles suspended in a flux medium. The solder paste is applied to the PCB pads, and then the components are placed on top of…
What is wave soldering?
Wave soldering is a common method used for soldering electronic components onto printed circuit boards (PCBs) during the manufacturing process. It is primarily used for through-hole components, which have leads that pass through holes in the PCB. The process of wave soldering involves the following steps: Preparation: Before wave soldering, the PCB is prepared by…
What Is Gerber File
The term “Gerber file” is commonly used in the field of electronic circuit board design and fabrication. It refers to a standard file format that contains the information necessary for manufacturing printed circuit boards (PCBs). Gerber files are generated by electronic design automation (EDA) software, such as PCB layout tools, and they provide a detailed…
Glass Transition Temperature
(Printed Circuit Board) fabrication, “TG” stands for “Glass Transition Temperature.” The glass transition temperature is the temperature at which a material transitions from a rigid, glassy state to a softer, more flexible state. In PCB fabrication, TG refers to the glass transition temperature of the base material used for the PCB. The TG value is…
What are the specific requirements for Class 3 electronic assemblies in IPC-610?
Class 3 electronic assemblies in IPC-610 have the most stringent requirements due to their application in areas where high reliability and performance are critical, such as aerospace, medical devices, and military equipment. The specific requirements for Class 3 electronic assemblies include: 1. Component Placement Components must be accurately placed and aligned according to the design…
Understanding IPC-610 Standards for PCB Manufacturing
IPC-610 is a widely recognized standard in the printed circuit board (PCB) industry. It provides guidelines and requirements for the acceptability of electronic assemblies, including PCBs, during manufacturing and assembly processes. The standard covers various aspects of PCB production, such as component placement, soldering, cleanliness, and overall workmanship. Here’s an example of content related to…
