RoHS PCB Assembly Multilayer HDI Board Custom PCBA for Consumer Device
Description of PCBA Assembly Printed Circuit Board
THT stands for Through-Hole Technology, which is a method of electronic component placement and soldering on a printed circuit board (PCB). In THT, electronic components are inserted into pre-drilled holes on the PCB and then soldered in place.
THT technology was widely used in the electronics industry before the advent of SMT technology. Through-hole components are typically larger and require more space on a PCB than SMT components. However, through-hole technology has several advantages over SMT, including:
1. Higher mechanical strength: The components are held in place more securely than SMT components, making them more resistant to mechanical stress and vibration.
2. Easier to prototype: THT components are easier to work with during the prototyping stage because they can be inserted and removed from the PCB more easily than SMT components.
3. Better heat dissipation: Through-hole components have a larger surface area, which allows for better heat dissipation than SMT components.
4. Better electrical properties: THT components have a lower inductance and better signal integrity compared to SMT components.
The THT process involves several steps, including drilling holes in the PCB, inserting components into the holes, and then soldering the components to the PCB. While through-hole technology is less common in modern PCB manufacturing, it is still used in some applications where its advantages are critical, such as in high-voltage or high-current applications, or where the components are subject to mechanical stress or vibration.
