When assembling a printed circuit board (PCB), components are mounted onto the board through one of two primary methods: Surface Mount Technology (SMT) or Through-Hole Technology (THT). Each method has distinct advantages and is suited to different applications depending on the project requirements.
SMT is a process of constructing electronic circuits by placing components directly onto the surface of a PCB. Unlike the earlier through-hole technology, which required drilling holes for component leads, SMT simplifies the manufacturing process while enabling smaller, more intricate designs.
When it comes to assembling Printed Circuit Boards (PCBs), there are two primary technologies: Surface Mount Technology (SMT) assembly and Through-Hole Technology (PTH) assembly
Printed circuit board (PCB) assembly is at the heart of electronic components and gadgets. Designers typically choose between two primary techniques for mounting components on PCBs: SMT (Surface Mount Technology) and PTH (Plated Through Hole).
A PCB is a substrate or laminate that supports and connects electronic components to enable various device functionalities. Common substrates include FR4 (flame retardant material), but there are alternatives such as polyimide for flexible designs. PCBs are categorized by layers—single-sided, double-sided, and multi-layer—and by substrate type (rigid, flexible, or rigid-flex combinations)
Flexible PCBs (printed circuit boards) provide the ability to bend and conform to various shapes, making them an essential technology for space-constrained and dynamic applications. A 2-layer flex PCB contains a flexible dielectric layer sandwiched between two conductive copper layers. Designing these PCBs requires unique considerations, including material selection, layout techniques, manufacturability, and reliability.
SMT, the short form of Surface Mount Technology, a type of PCB (Printed Circuit Board) assembly technology, refers to the technology of getting components directly soldered onto the surface of PCB to replace THT (Through-Hole Technology) that has to make use of drilling holes
