Donner Company started its operations in 1985 and developed specialized capability in manufacturing circuit boards for experimental devices and for pilot production runs. The company uses “Solder mask over Bare Copper” (SMOBC) technology which is a popular technology for denser circuit patterns and more reliable final product. Automated processes as well as manual processes are used to perform medium-duty‚ short-cycle‚ repetitive tasks. They promise a delivery within three weeks for orders less than

Donner Company Case Overview Donner Company manufactures printed circuit boards for both large and small companies‚ specializing in experimental devices and for pilot production runs in the late 1980s. The circuit boards that it produces are made from thin sheets of narrow metal strips and insulating material. The process to produce each circuit board is very meticulous and involves many intricate steps. Their process‚ otherwise known as the “soldermask over bare copper” (SMOBC) process includes

The Donner Party The Donner Party was a group settlers during the 1800’s that planned on moving West to settle for new life. In hopes of reaching California quickly‚ as they had left late in the season and they decided took a new route. One man that considered himself an expert guide had only traveled this new route. He led them through the Sierra Nevada Mountains by notes he left on the trail for them. This route turned out to be extremely dangerous and cost many people their lives and families

Most of us have all heard of the Donner Party. They were the group of traveling families‚ trying to reach the new land. Along the way‚ they were said to have partaken in cannibalism to survive harsh winters. Recent studies are trying to prove if in fact all of the survivors had joined in the cannibalism. If in fact they were all cannibals or not‚ only time and more extensive research can tell. In April of 1846‚ the Donner Party set off from Springfield‚ Illinois in search of a new life and land

Order Size for drilling: * The Manual press needs 15 min for set up‚ in addition to 0.08 min for every hole. Knowing that the typical circuit board has 500 drilled holes‚ then run time will be 0.08*500 = 40 min / board. Therefore‚ time taken to drill N boards manually will be equal to : 15 + 40(N) * On the other hand the CNC drill needs 240 min for set up‚ in addition to 0.004 min for every hole. So run time will be 0.004*500 = 2 min / board. Then the time taken to drill N boards by CNC drill
