PNC Inc. is currently manufacturing RoHS compliant PCBs. We are currently using ISOLA (for multilayer and double-sided PCB’s) and NANYA (for double-sided PCB’s) brand products to manufacture our RoHS compliant PCBs. Although not limited to these brands, we are always looking for more product options to better serve you.
We can provide you with UL approved PCB's boards with a variety of final finishes that meet the requirements of RoHS, REACH and Conflict Metals regulations
Since the adoption of the RoHS directive two additional regulations have been enacted that have had a significant effect on the PCB manufacturing industry; REACH by the EU and the Conflict Metals initiative in the USA. RoHS has matured through the last few years and the majority of the concerns voiced early on have not materialized. Similar legislative action has taken place in the Asian Pacific region including China and Japan among others. In the US, California has restricted the sale of electronic devices that do not meet the RoHS directive.
RoHS or the restriction of hazardous substances focuses on the use of six specific substances; Lead, Mercury, Cadmium, Hexavalent Chromium, Polybrominated biphenyls and Polybrominated diphenylether. The last two are fire retardants used in several types of plastic. The amount of each substance used in a product is limited to a maximum concentration based on the weight of homogeneous material used in a product.
Our High Tg materials (ISOLA 370HR and IS410) are specially formulated for superior performance though multiple thermal excursions, passing 6x solder tests at 288 degrees C. These materials are also optimized for enhanced drilling performance allowing high aspect ratio holes down to 8 mils. in diameter. Their unique resin chemistry provides CAF resistance with the benefit of long-term reliability of boards built with small feature designs. Along with these attributes, they bring improved productivity with their standard cure system while using current fabrication techniques.
