Design for Medical Electronics Assembly
New technologies demand well organized design-for-assembly procedures. In addition, there are different considerations for prototype assembly and production assembly, with each requiring a specific design skill set and equipment.
The assembly of medical devices continues to increase in complexity due to newer, more advanced electronics technologies. The current trend toward portable wireless and handheld devices, in particular, is playing an important role in this area. Compact medical devices like these generally rely on such sophisticated electronics as digital signal processors, field-programmable gate arrays, and radio frequency and mixed-signal chips. Making printed circuit board (PCB) assembly even more challenging is the fact that these chips are often packaged in fine-pitch ball-grid arrays (BGAs) or chip-scale packages (CSPs) with pin counts ranging from 256 to 1,052 and more, and with pitches of as little as 1 millimeter or even 0.5 millimeter in newer products.
