Sulfur-free paper is a special paper used in PCB silver process" for printed circuit board manufacturers. To avoid chemical reactions between silver and sulfur in the air.The function is to avoid the chemical reaction between the silver in the electroplated finished product and the sulfur in the air, as the chemical reaction can make the product turn into yellow and caused by the defect.The operator should pack the finished electroplating product as soon as possible with suffer free paper ,further more they should wear professional gloves and product electro surface can not be touched.
CAUTIONS:
Sulfur-free paper is a special paper for PCB surface treatment process. It is stored in a cool and ventilated warehouse. Should be stacked flatly, avoiding direct sunlight, away from fire and water sources, no close to high temperature, moisture environment, and avoid to contacting with liquids (especially acids and bases)!
