What is the primary purpose of using layout tape in the assembly process?

The primary purpose of using layout tape in the assembly process is to mark hole locations without damaging the surface. Layout tape is designed to be easily applied and removed, allowing for precise marking on various materials without leaving adhesive residues or causing damage. This is particularly important in aerospace applications where surface integrity is critical, and any markings that could cause corrosion or other issues must be avoided.

While layout tape can be used for various functions during assembly, marking hole locations is a key aspect because it ensures that the drilling or fastener placement is accurate, contributing to the overall quality and integrity of the assembly. This function is essential to facilitate a precise and efficient workflow in the assembly process.
