Electronic Components

Through-hole Technology

The first PCBs used through-hole technology, mounting electronic components by leads  inserted through holes on one side of the board and soldered onto copper traces on the other side. Boards may be single-sided, with an unplated component side, or more compact double-sided boards, with components soldered on both sides.

Multiple lead devices

Components like integrated circuits can have upwards of dozens of leads, or pins. For electronic components with two or more leads, for example, diodes, transistors, ICs, or resistor packs, a range of standard-sized semiconductor packages are used, either directly onto the PCB or via a socket

Surface-mount technology (SMD)

Surface-mount technology emerged in the 1960s, gained momentum in the early 1980s, and became widely used by the mid-1990s. Components were mechanically redesigned to have small metal tabs or end caps that could be soldered directly onto the PCB surface, instead of wire leads to pass through holes. Components became much smaller and component placement on both sides of the board became more common than with through-hole mounting, allowing much smaller PCB assemblies with much higher circuit densities.

Types of SMD Components

According to the function of SMD components, they can be classified as follows, the letters in brackets represent their identification on the PCB. • Chip Resistor (R), Network Resistor (RA/RN), Capacitor (C), Diode (D), LED (LED), Transistor (Q) (SOT-23 and SOT-223 (larger)), Inductor (L), Crystal Oscillator (X), IC (U),

Electromechanical Components

An electromechanical component is one that uses an electrical signal to cause some kind of mechanical change, such as motor turning. These normally use an electrical current to create a magnetic field which causes a physical movement. All types of relays and switches are available in this category.

We have wide range of products, starting with trimmer potentiometers variable resisters which play a role in many fields of industry these products cover from small signal switches for settings and control and measurement devices, to high power switches for operations, such as push buttons and toggle switches.
