Leading the Movement Toward Miniaturization Because we lead the miniaturization movement, we offer the widest line of pitches available. As these pitches continue to shrink, the mechanical challenges become extreme. Tolerances Become Even More Critical Because the option of aligning off the device leads is not an option on leadless devices, large perimeter and positional tolerances are often of greater concern with the QFN devices of today. With these devices we have seen the greatest effect of decreasing device sizes and unchanging manufacturing tolerances. When you take into consideration the outside package tolerance, pad size tolerance, and pad positional tolerances, guaranteeing contact is a tall order. To address this we work closely with you to best understand your specific application needs. For example, even though the device print reads +/- 0.2 mm, often times the customer receives product within a range of 0.05mm. For those customers who do not have this luxury, we have had to be a little more creative. Lot size nest inserts and reduced crown tips are a few of the options available for these concerns.
