PCB 7x9cm


SKU: 000363 Category: Tags: , ,


A PCB (Printed Circuit Board) measuring 7x9cm is a foundational component in electronics manufacturing and prototyping. It serves as a substrate for mounting and interconnecting electronic components to create functional circuits. The dimensions 7x9cm refer to the width and length of the PCB, providing a suitable working area for designing and building various electronic devices and systems.

Key Features:

Size: The dimensions of 7x9cm indicate that the PCB has a width of 7 centimeters and a length of 9 centimeters. This size offers a moderate amount of space for mounting electronic components and creating custom circuits.

Single or Double-Sided: PCBs can be single-sided or double-sided. Single-sided PCBs have a conductive layer on one side, while double-sided PCBs have conductive traces on both sides, allowing for more complex circuit designs.

Materials: PCBs are typically made from various materials, with FR-4 (a flame-retardant glass epoxy material) being a common choice. The material used affects the PCB’s electrical properties and durability.

Conductive Traces: PCBs feature conductive traces (also known as traces or tracks) that connect different components and parts of the circuit. These traces are usually made of copper and are etched onto the board.

Mounting Holes: PCBs often include mounting holes for securing the board to an enclosure or other surfaces. These holes facilitate mechanical stability and assembly.

Silkscreen: PCBs can have a silkscreen layer that includes labels, component outlines, and other helpful information to assist with component placement and identification.

Copper Pads: Copper pads are areas on the PCB where electronic components are soldered. The size and arrangement of these pads vary based on the specific application.


Prototyping: PCBs of this size are commonly used for prototyping electronic circuits and systems. They provide a platform for designers and engineers to test and iterate on their designs.

Custom Electronics: PCBs are used to create custom electronic devices, such as hobbyist projects, embedded systems, and specialized control circuits.

Educational Projects: Educational institutions use PCBs to teach students about electronics, circuit design, and soldering techniques.

Small-Scale Electronics: PCBs of this size are suitable for small-scale electronics projects, such as DIY gadgets, sensors, and simple automation systems.

Product Development: PCBs are a key component in the development of electronic products and gadgets, allowing engineers to transform concepts into working prototypes.

Control Systems: They are used in control systems and embedded applications for various industries, from automotive to consumer electronics.

IoT Devices: PCBs play a crucial role in the development of Internet of Things (IoT) devices, enabling connectivity and data processing.

A PCB measuring 7x9cm provides a versatile platform for a wide range of electronic projects, from basic prototypes to small-scale custom electronics. Its size allows for flexibility in design and component placement, making it a valuable tool for engineers, hobbyists, and product developers in the electronics industry.
