Time to Delamination (TMA Method)
ScopeThis method describes the method for deter-mining the time to Delamination of laminates and printedboards through the use of a thermomechanical analyzer(TMA). Applicable DocumentsIPC-TM-650 Method , Glass Transition Temperatureand Z-Axis Thermal Expansion by Test SizeSpecimens shall be approximately mm mm [ in x in] by the thickness of the Quantity and SamplingUnless otherwise specified,two specimens shall be tested, to be taken from random loca-tions of the material in Apparatus or Drying ChamberAir circulating oven capable of main-taining 105 2 C [221 F]. Cutting EquipmentDiamond blade or wheel, sandingequipment, or equivalent, to provide a specimen of the sizeand edge quality DesiccatorDessication chamber capable of maintain-ing an atmosphere less than 30% RH at 23 C [ F]. TesterThermal Mechanical Analyzer (TMA) capable ofdetermination of dimensional change to within mm[ in] over the specified temperature Specimen clad laminates shall be tested as is.
