The Manufacturing Process for Electronic Assemblies

Motor vehicles, particularly commercial trucks and buses are using an increasing number of electronic sub-assemblies. These modules contain circuit boards with 6 - 8 layers of interconnected circuitry and require the assembly of 400 parts. The manufacturing process can involve 22 separate processes including automatic assembly high volume soldering, robotics, coatings and automatic test. These processes can cause costs to rise dramatically if functional or vehicle interface requirements are changed late in the design process.
