Abstract
One embodiment of a robust process for the repair of a solder bridge defect in a Surface Mount Technology micro-electronic circuit assembly with fine pitch components. The defective solder joint is heated by various means and a cold gas jet blast is applied to the defective solder joint. An effect is created whereby the solder inducing the defect is conveyed away by the impact of the cold gas jet blast. The advantages of this embodiment include scalability for pin spacing and elimination of heat induced latent defects. The process is applicable to any pin spacing, but is of particular usefulness with pin spacing of 0.025 inch or finer. Other embodiments are described and shown.
