Can PCB Assemblers Be Used in Military Applications?

PCB Assemblers

Military PCBs must be able to perform under the harshest conditions, which is why they are designed with special considerations. These considerations include the material, components, and manufacturing process. Using the right contract manufacturer is critical to ensuring that the finished product meets or exceeds military standards. Levison Enterprises has the experience, quality standards, and certifications to meet military PCB requirements.

Printed circuit boards (PCBs) for military applications must be able to withstand extreme heat, humidity, and vibration. They also require special surface finishes and coatings. Acrylic based sprays and immersion silver are common coatings, but high strength epoxies can be used as well. These coatings help to insulate components, protect them from excessive heat, and reduce vibration that can crack solder. In addition, the metal substrates used in military pcb assembler must be strong enough to resist oxidation and dissipate heat efficiently. Anodized aluminum is a popular choice because of its ability to resist oxidation and offer weight advantages.

The assembly process for military applications can be quite complex, and there are several different steps involved. The first step is prepping the board, which involves applying solder paste and then placing the electronic components on the board. Next, the assembler will solder each component to the board. This can be done either manually or with a pick-and-place machine.

Once the components are soldered, the assembler will test the board for any issues. If everything is in order, the assembler will then apply a conformal coating to the surface of the board. This helps to insulate the circuit board from moisture and humidity, as well as reduce vibration.

Another important aspect of military PCB assembly is ensuring that the bare board has the appropriate copper weight. This is important because a board with the incorrect weight can cause problems when it is soldered. The ideal copper weight for a bare board is four ounces per square foot.

Moreover, PCB assemblers play a crucial role in fostering innovation by collaborating with engineers and designers to optimize the manufacturability of electronic products. Their insights into assembly techniques, component availability, and production constraints can influence the design process and ultimately impact the performance and cost of the final product.

Finally, it is critical to ensure that the assembler follows all the necessary quality control procedures. This includes establishing a system for tracking the materials, components, and assemblies throughout the production process. This will help to prevent unauthorized individuals from gaining access to the data that is contained in the military application. It is also essential to establish a system for identifying and correcting any malfunctions, errors, or defects. This can be accomplished through a series of inspections and tests that are carried out throughout the assembly process.
