Thus, treatments that solve only \n one problem don't necessarily offer a reliable long term solution. For example, \n cleaners · do not prevent the re-entry of contaminants or the reformation of con- \n taminant films; nor do they offer any lubrication. They must be used each time a \n connector gets dirty. Lubricants in themselves are rarely cleaners. Corrosion inhibitors \n are neither cleaners nor lubricants and are often specific to one type of metal or \n plating. Unsaturated oils used as contact treatments can cross-link under the in- \n fluence of elastomer or thermoset plastic curing agents and accelerants.","bbox":{"left":0.193529,"top":0.208625,"width":0.7058850000000001,"height":0.14198899999999998}},{"text":"While resident in the connector, Stabilant 22 performs several concurrent functions. \n Its very presence in the contact gap will prevent the entry of outside contaminants. It \n has sufficient surfactant action to lift surface contaminants and hold them in suspen- \n sion. In cases where corrosion products are present Stabilant 22 will penetrate them \n and prevent rectification effects. Due to its high dielectric constant it will act to form \n a capacitative layer which is in parallel with whatever residual resistance exists in the \n contact increasing the passage of AC signals. Given sufficient DC bias within the gaps \n of the contact the thin film of Stabilant will \"switch\", conducting by quantum tunnel- \n ing and thus limit the resistance of the contact to a serviceable level.","bbox":{"left":0.314742,"top":0.363101,"width":0.5831089999999999,"height":0.137861}},{"text":"•","bbox":{"left":0.170343,"top":0.520464,"width":0.005546999999999996,"height":0.016832999999999987}},{"text":"In what forms is Stabilant available? \n The Stabilants are available in two forms; as a concentrate (Stabilant 22) and as an \n isopropyl alcohol-diluted form (Stabilant 22A). Because of the 4: 1 dilution, a given \n size container of Stabilant 22A will cost about one-fifth the amount of a container \n of Stabilant 22 as it contains only one-fifth the amount of the concentrate. A third \n packaging is available. Stabilant 22S packages the concentrate such that it occupies \n one-fifth the volume of an otherwise empty container. This allows the end-user to \n add his own diluant and saves the added costs of shipping isopropyl alcohol, as well \n as allowing the end-user to use an alternate diluant such as one of the Freon™ \n solvents. In addition a 1/2 ml vial of Stabilant 22A is available for manufacturers to \n include with plug-in circuit boards.","bbox":{"left":0.19033,"top":0.51927,"width":0.705251,"height":0.17417899999999997}},{"text":"•","bbox":{"left":0.16799,"top":0.71234,"width":0.005546999999999996,"height":0.016832999999999987}},{"text":"What is the difference in use of these materials? \n Stabilant 22 is most useful where the connections are out in the open - such as \n card-edge connectors or where the lubricating properties of the material are useful - \n such as an aid to installing microprocessor IC's or on switches. Where the connec- \n tions are not too easy to get at or where the user wishes to apply the material to \n something such as a socketed IC (without removing the IC from its socket) it is easier \n to use the alcohol diluted form (Stabilant 22A).
