Surface Mount Technology Question & Answers

August 25, 2022 By WatElectronics

This article lists 75 Surface Mount Technology MCQs for engineering students. All the Surface Mount TechnologyQuestions & Answers given below include a hint and a link wherever possible to the relevant topic. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up on the fundamentals of Surface Mount Technology.

Most electronics nowadays are manufactured using SMT (Surface Mount Technology). It is advantageous because the production is automated as well as soldering. The devices made from SMT are efficient & economical.

Electrical components are mounted on PCB (Printed Circuit Board) directly in Surface Mount Technology. The mounted component through this technology is known as a Surface Mounted Device. This method is a replacement for Through Hole Technology.

Initially in industries, components are fitted using the method of construction known as Through Hole Technology. The demand for SMT is increased because SMTs increase automation manufacturing and leads to reduced cost with improved quality.

More components are accommodated in the lesser area by using SMTs. Based on the requirement and suitability both of these technologies are used. Large transformers and Power semiconductors i.e., heat sinks are not suitable for Surface mounting.
