SMT Advantages over Thourgh Hole in Chart format| 24 May, 2001
Does anyone have any sort of Chart comparisons for the advantages of SMT over Through Hole? I realize this is old material and for that reason I believe it's now hard to come by (in presentation format). I know someone trying to convince a mature entrenched Through Hole company to make the conversion, but their having a hard time convincing them of the benefits.

No chart for you, but I will comment that a prudent product manager would require a substantial reason to accept the risk of product failure and loss of profit to redesign his / her product.
We merrily assemble many boards each month that were designed in the 1960s using pre-computer tape methods. These methods used black adhesive tape of various widths and donut shapes to create the photoartwork for the boards. [Stop and think about that for a while.]
Our product manager on this line stated that "I will use the last PTH part on the planet before I redesign this product!!!" Not to say there isn't reasons to convert PTH designs to SMT, but I can't think of many that would be compelling.
