Today's advances in PCB manufacturing technology include addressing certain design and manufacturing processes and their impact on the environment. Environmental and public health concerns are driving tougher legislation to restrict the use of lead in electronic devices. KCE, like other responsible members of our industry is working hard with our customers and raw material suppliers to move to viable alternatives to lead based HASL such as lead free solder, immersion Tin, and the use of organic coatings such as Entek. In others areas we are either exploring or have introduced items such as halogen free resin material, polymer thick film carbon(Carbon Card Contacts replacing conventional nickel/gold contacts and thus removing the hazardous nickel/gold plating solution) and the replacement of feed & bleed systems for oxidizing cupric chloride etching with an electrolytic regeneration system.
