I don't want to discourage you , but here are a few words of caution if you are 
also looking at reliability evaluations:

The die is critical, as is the lead material. Both are key factors in the long 
term reliability. Alloy 42 is know to have field failures. The die and moisture 
can result in some delamination if you are not cautious.

When you are looking, ask if they are daisy chained metal or actual die. To meet 
this, sometimes, your actual component supplier can produce daisy chained parts 
for you. We have had some success with suppliers in that respect.

Best of Luck,
Allen

Having high quality dummy components with various internal connection =
patterns is very valuable for qualifying equipment, process, and =
products. I believe that we as an industry should facilitate the =
availability of such components.

I have a need for dummy 26 pin TSOP, 1.27 mm pitch. It is my =
understanding that Topline has a very long lead time, several months, =
for such components because there is such a worldwide demand for TSOP =
molding capacity. Is this true?

Is there someone out there who might be able to help Topline get access =
to molding capacity if this true?

Do Techneters know of any other supplier of dummy components which can =
supply fully shorted or daisy chained 26 pin TSOPs quickly?
