I am not familiar with the "HALT" terminology. Do you mean HAST testing? As for thermal fatigue, the most severe conditions are typically those cited for military and/or satellite applications. There are several temperature ranges that are used to

Just so that you know, the 5DX does laminography. Like the word lamination, laminography takes a series of short focal length xrays, each a little deeper than the previous. Microlaminography allows layer by layer information to be measured in 'slic

Some of our boards have over 700 LED's, so looking for the long leads is the most accurate way to check polarity. Also, not all LED's have a flat side and tinted domes can make it difficult to see the internal structure. Auto insertion didn't work, f

I go with DaveF's advice. You are probably curing the glue too fast. Another phenomenon that I have experienced was during glue cure and solder paste reflow simultaeously. A good reason to run a glue cure profile seperately from solder paste reflow
