The article analyzes the effectiveness of contract cleaning for printed wiring assembly (PWA). Over the long run, outsourcing may reduce our total operating and maintenance costs as well as our technical support and equipment investment requirements. For most printed circuit assembly and soldering operations outsourcing the post-solder defluxing operation is definitely a mistake. Outsourcing can lead to product quality problems and overall cost issues. In the case of the double-sided, dense assemblies, cleaning after each of the soldering operations is mandatory for most applications and highly recommended in all cases. If the outsourced cleaning/defluxing operation is located onsite, the management, quality control and cleanliness testing of the cleaning operation could become complicated.
