The IPC temperature charts are published as Figure 6-4 in IPC –2221, “General Standard on Printed Board Design.” The Figure is reprinted on page 2.
The first observation to be made is that the curves and axes do not line up exactly. This is not a problem in scanning the charts or in reproducing them here! It is a result of the now recognized fact that the originals have been long lost and these copies have been recopied, rescanned, and redrawn countless times during the last 40+ years! It is remarkable (and a testimony to the care that has always been taken) that they are still as faithful to the originals as they are! There is a renewed effort underway by the IPC and interested parties in updating the charts. UltraCAD is proud to be making a small contribution in this effort.
