Double-Sided PCB (1/1) in FR4

Double-Sided Printed Circuits (1/1) in FR4

Industrial Manufacturing – Microcircuitos S.A.S.

AtMicrocircuitos S.A.S.we manufacturedouble-sided PCBs (1/1) in FR4, designed for applications that requirehigher component density, efficient interconnection, and high reliability.

Our boards meetindustrial quality standards, ensuring stable performance both in assembly processes and during the operation of the final product.

1. Thermal performance and reliability in assembly

The double-sided FR4 PCBs are developed to withstand the thermal and mechanical requirements of the modern electronics industry:

• High thermal and mechanical stability

  The excellent adhesion between copper layers and FR4 substrate reduces the risk of delamination, even in repetitive soldering or rework processes.

• Compatibility with industrial soldering processes

  Designed to operate reliably up to320 °C, compatible with:

  • Manual assembly with soldering iron

  • Wave Soldering

  • Selective soldering processes

2. Base material: industrial standard FR4

We useepoxy resin FR4 reinforced with fiberglass, ideal for applications that demand stability and precision:

• High structural rigidityand impact resistance.

• Excellent dielectric properties, with low moisture absorption.

• Dimensional stability, essential for the correct alignment of holes and pads on both sides of the circuit.

3. Copper thickness

• We offer different copper thickness options to meet the electrical requirements of the design:

• 1 oz / 1 oz (35 µm per side)

  Standard configuration for signals, control, logic, and general applications.

• 2 oz / 2 oz (70 µm per side)

  Ideal forhigher current capacity, improves thermal dissipation and reduces electrical losses in

• power traces.

4. Plated Through Holes

Double-sided PCBs includeplated through holes (PTH)that allow for a reliable electrical connection between both sides:

• Optimizes the use of circuit area

• Enables more compact and functional designs

5. Industrial applications

Microcircuit's double-sided FR4 PCBs are widely used in:

• Electronic and industrial controllers

• Power supplies and converters

• Automation equipment

• Advanced LED lighting

• More complex electronic modules
