Printed Circuit Board Assembly for Aerospace Industry

The operational efficiency of electronic devices is one of the critical requirements in the aerospace industry. These devices are operated in extreme conditions where high temperatures, chemicals, and vibrations may be involved. The printed circuit board assemblies used in these systems are designed keeping these challenges in mind. Therefore, these circuit board assemblies need special consideration in terms of material, sizes, designs, and so on. This is where Suntronic can help. We can provide low volume and high volume aerospace PCB assemblies and quick-turn prototypes. We are aware of the stringent quality demands for printed circuit boards in the aerospace industry. The electronic systems operated within the aircraft and on-ground contribute to the safety of human lives. Thus, all printed circuit board assemblies are subjected to rigorous testing for accuracy, performance efficiency, and quality before shipping to the customer.

Our Aerospace PCB Assembly Service Capabilities

The following PCB assembly capabilities that we have developed over the years have helped us meet stringent demands and customer requirements effectively.

  • Types of PCBs: Rigid, rigid-flex, and flexible circuit boards in single-sided, double-sided, and multi-layer configurations with or without high density interconnects
  • Mounting Technologies: Surface mount (SMT), plated through-hole (PTH), and mixed technology PCBs (SMT and PTH)
  • Materials: FR4, polyimide, and Arlon and others.
  • Copper Weight: UL up to 6 ounces, extreme copper capabilities, multiple weights on internal and external layers
  • Lead times: 24 hours to 5 days for prototypes and small production runs from the time a kit is complete, and up to 20 days for medium to high volume production
  • Manufacturing capabilities: Mechanical and industrial designs, design for manufacturability (DFM), new product introduction (NPI)

In addition to the above, we utilize the following processing capabilities:

  • Microwave and RF PCBs
  • Buried and blind vias
  • Non-conductive and conductive filled vias
  • Heatsinks
  • Metal clad PCBs
  • Controlled routing through Z-axis

Beneficial Features of Aerospace PCB Assembly Solutions Offered by Suntronic

Our aerospace PCB assembly services have gained immense popularity in recent years. We believe the following factors of our PCB assemblies are well-appreciated by our clients.

  1. Use of Industry-grade Components: We understand that the use of PCBs in commercial-grade electronic equipment and aerospace electronic equipment is quite different. In the aerospace industry, electronic devices often have to withstand challenging environmental conditions including high temperatures. To address this, our experts use high-temperature laminates (as recommended by clients), aluminum substrates, and copper compounds that can efficiently perform in challenging environments without deformation.
  2. High Current Loads: We understand that PCB assemblies used in aircraft applications are subjected to high current loads. Thus, they are tested for the required current loads in simulated environments before shipping to the client.
  3. Use of Thermal Compounds: We use thermal compounds in applications involving high heat dissipation. The use of thermal compounds and press-fit components also helps us assure security from shocks and vibrations when the electronic device is being operated inside the aircraft.
  4. Differentiation of Radio Frequency Components: Most aerospace electronics applications utilize high and low-frequency components. These components need to be differentiated clearly, and their contacts must be minimized. Our experts address this factor during the design phase to avoid signal quality degradation. In addition to this, they include shielding in important places and also try to keep short transmission lines to assure high signal quality.
  5. Weight Reduction: The printed circuit boards in aerospace applications are lighter than regular commercial application boards. To meet this requirement, our experts always use aluminum substrates that are lightweight and can withstand high temperatures. For improving their efficiency, thermally conductive prepregs are used with these substrates.
