Colleagues: IPC will hold the first meeting of a new Task Group which will be looking to expand on the MIL-D-275 current carrying capacity charts. The following is a list of questions for the task group to tackle: How to do the following effect the thermal properties of a conductor/board area? 1) orientation of board -verticle (conductors on top vs. bottom) vs. horizontal 2) length of conductors (shorter) 3) pads & leads (adding components; heat generator or heat sink) 4) width vs. thickness (form factor) 5) dielectric material -negligible 6) conductor material effect (electrodeposition, foil, plating) 7) adjacent conductors 8) internal vs. surface conductors The new task group will be meeting on Tuesday, October 27 - 5:15pm - 6:30pm during IPC/SMTA Electronics Assembly Expo in Providence, RI. Interested parties are invited to attend and/or send their comments to the IPC. For more information visit our website...click on the component labeled IPC/SMTA Electronics Assembly Expo.
