Contamination of circuit boards can bring about severe degradation of insulation resistance and dielectric strength. Cleanliness of completed circuit boards is, therefore, of vital interest. For those companies who have established circuit board cleaning procedures, the MIL Spec P-28809 has been used as a guideline for control. Now a simple `on line` test for the relative measurement of ionic contamination has been developed. This fast and economical method for testing circuit board cleanliness uses a Myron L Company Ultrameter II™ 4P or 6P, a suitable container, and a mixture of Dl (deionized) water and alcohol.
