One of the two most common methods of attaching electronic components to PCBs is the through-hole or through-hole process. This technology is older than SMT, and for many years, it was the standard technology for PCB assembly. When surface mount technology became popular in the 1980s, many people thought it would make through-hole PCB assembly obsolete. However, through-hole technology has several advantages that make it still a preferred choice for certain applications.
Basic soldering guide on how to solder electronic components to a printed circuit board (PCB). This is a detailed and complete soldering guide for both automated soldering in mass production and manual soldering in PCB rework and repair.
SMT vs. Through-Hole – Disadvantages of SMT vs. Through-Hole
Since not all basic electronic components are available for surface mounting, the actual area savings on the board will depend on the percentage of through-hole components replaced by surface mount components. The three types of surface mount offer varying degrees of benefit depending on the component combination.
SMD soldering or surface mount technology assembly requires different SMT equipment and more experience and expertise. SMT PCBs have flat tin-lead or gold-plated copper pads without any holes. These traces are called “pads
The lower thermal resistance between the BGA package and the PCB components is another advantage of this type of package. This allows heat to flow more freely, resulting in better heat dissipation and preventing the device from overheating.
Surface Mount Technology (SMT) is widely used in the PCB assembly process, but like any complex manufacturing technology, it is not immune to defects. Whether you’re dealing with solder balls, bridging, tombstoning, or unmelted solder paste, troubleshooting is a key part of ensuring high-quality SMT production.
A Double-Sided PCB (also known as a Double-Layer PCB) is a type of printed circuit board where both sides of the substrate are used for placing electronic components and conductive copper traces. Unlike single-sided PCBs, which have a copper layer on only one side, double-sided PCBs feature conductive layers on both sides of the board, connected via plated-through holes (PTH), allowing circuits to connect between the top and bottom layers.
Surface Mount Technology (SMT) is a widely used method for manufacturing PCBs, where Surface Mount Devices (SMD) are directly mounted onto the surface of the PCB. This technology allows for a more compact design and higher component density compared to traditional through-hole mounting.
PCB (Printed Circuit Board) substrate materials are the backbone of a PCB assembly, providing the necessary foundation for copper tracks and electronic components. The choice of PCB material plays a critical role in determining the performance, durability, and overall reliability of the PCB. These materials can be resin-based, fiberglass-based, epoxy-glass, metal-based, or flame-retardant, and they are selected based on the specific requirements of the PCB design and its application.
