Clariant's new Humitector Type 2 Non-Reversible Humidity Indicator Cards contain a patent-pending non-reversible 60% humidity spot indicator which enables them to indicate whether dry packed surface mount devices (SMDs) have been exposed to high levels of moisture at any point during shipment or storage.
This unique innovation offers a major step forward in preventing moisture-compromised surface mounts from entering production. Until now, users of moisture sensitive, reflowable surface mount devices have had little choice in the humidity indicator cards required for use in protective packages governed by the J-STD-033 standard. Typical Type 1 cards offer only reversible indicators that reflect current (dry or humid) conditions at the precise time of checking. The new Humitector Type 2 Non-Reversible Humidity Indicator cards provide verifiable color change accuracy and meet or exceed applicable European Chemical Bureau regulations. They have been approved for use by the Joint Electron Device Engineering Council (JEDEC) in the latest revisions to IPC/JEDEC J-STD-033 (J-STD-033D). "As originators of the color change humidity indicator card, we are very proud to lead the way with this advanced option for surface mount devices," said Menghwee Toh, Head of Clariant Cargo & Device Protection, Asia.
