One of the most critical factors in preventing corrosion from occurring in electronics is maintaining the state of cleanliness. This is not an easy feat to achieve. Corrosion is defined as the deterioration of a material or its properties due to a reaction of that material with its chemical environment. [1] So, to prevent corrosion from occurring, either the material or the chemical environment must be adjusted. Adjusting the material usually means application of a protective coating or replacing a more reactive material with a less reactive material. Adjusting the chemical environment usually means removing ionic species through cleaning, and removing moisture, usually with a conformal coating or hermetic package. Ionic species and moisture are problematic because they form an electrolyte which is able to conduct ions and electricity. Any metal that comes into contact with the electrolyte can begin to corrode.

Customers must be able to rely on accurate humidity indication as an assurance of SMD quality and fitness for processing and use. Without it, they might accept SMDs from suppliers that have already been irreparably damaged by moisture during storage or transit. Or, they might approve for processing SMDs that have been improperly or insufficiently heat-dried. Beyond the processing questions, there are financial questions: Where did the dry pack problems originate and who--supplier, customer, shipper--is financially responsible for the damaged SMDs? In response, Clariant, the originator of the color change humidity indicator card, and a member of the JEDEC's Subcommittee 14.1, "Reliability and Test Methods for Packaged Devices," created a new "non-reversible" halogen and cobalt dichloride free humidity indicator card. This HIC combines two reversible indicators (5% and 10%) with a new non-reversible (60% RH) indicator spot. (Figure 1) The 5% and 10% reversible spots work the way similar indicators do: they change color from blue (dry), to lavender, to pink (wet) to indicate humidity exposure at the indicated levels. If humidity levels drop, they will gradually revert back to blue.

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.

As electronics brands demand more sustainable materials and product reliability across their supply chains, Clariant brings two elements together to uniquely boost moisture-exposure assurance for dry-packed Level 2+ components. It is the only option for semiconductor manufacturers, integrated circuit companies and OEM suppliers to meet latest J-STD-033D preferences and increasing low-halogen & cobalt-dichloride-free specifications.
