IPC-CC-830 lating Compound for Printed Board Assemblies 5.1.1 Place the 0.3 cm [0.12 in] mandrel, in a stationary FED-STD-141 Method 2012 position, in the center of the test panel. 3 Test Specimens 5.1.2 Select one end of the test panel and within one sec- ond bend the panel 180°over the mandrel. 3.1 Four tin panels in accordance with FED-STD-141, Method 2012. Electroplated tin is also acceptable 5.2 Evaluation 4 Apparatus 5.2.1 Following the folding procedure, the test panel shall then be examined with 10x magnification for cracking and 4.1 Tin panels coated with conformal coating according to crazing. the coating supplier's recommendations. 4.2 2 Mandrel, 0.3 cm [0.12 in] diameter Material in this Test Methods Manual was voluntarily established by Technical Committees of IPC.
