As Karen says, kits are a great way to test out some possible solutions to the wide variety of issues facing Design Engineers today without having to commit to a minimum order quantity.
At Indium we have long subscribed to this process and have several kits available. We identified the most popular alloys in our wire, ribbon and preform product lines and offer them in 3 foot quantities in kits. Because preforms are highly customized parts, the ribbon kit fills in nicely and allows users to cut the ribbon to the size they need.
