PCB 2 layer

2-layer circuits (also known as Double-sided, Dual-Side or DSPT circuits) are the entry port for higher technology applications. They allow you to make PCBs with higher density with closer slopes, alternating between the top and bottom layers using Vias holes.
Today, double-sided circuit boards are perhaps the most popular type of PCB produced in the industry.

Advantages of double-sided PCBs:
• More flexibility for designers
• Increase of the density of the circuit
• Relatively lower costs
• Intermediate level of circuit complexity
• Reduced circuit size (which can reduce costs)

There are unlimited applications for this type of projects. Surface mount with fine pitches, high copper thickness, high and low temperature, silver and gold finishes are just a few examples of 2 layer PCB applications.

Here are  some areas where double-sided PCBs can be used:

• Industrial controls
• Converters
• Monitoring relay
• Instrumentation
• regulators
• UPS systems
• HVAC
• Led illumination
• Fixed discs (HD)
• Printers
• Telephone systems
• Power monitoring
• Automotive dashboards
• Test equipment
• Amplifiers
• Traffic systems
• Vending machines
