A start up team for a company building the world's first high-density Chip Scale Package, or CSP, was working to deliver a working part to a large computer company. The chip carriers were all made by hand using bench top chemistry and old equipment. 

The team was down to only one chip carrier and one work station computer chip.  With only 4 hours before the order was due to ship. Each of the 302 connections had to be made one-at-a-time under a microscope using an old bonding machine.

The next step was to add the liquid encapsulate and harden the material in an oven. The resin wasn't completely cured in time for shipment so it was pulled from the oven and wrapped in plastic foam to keep it hot enough so the resin would complete the cure while it shipped.

The box was physically hot when the Fed Ex driver came to pick up the shipment and rejected it. How did the team explain the heat and convince the driver to accept it so they could meet their deadline?

Here's the rest of the story.

Thinking quick, one of the team members explained to the Fed Ex driver that the package contained fresh cookies just out of the oven for Grandma. The box made it to the coast, the part worked, and today this company is a highly successful chip manufacturer.
